On the market, there are many flame-retardant pressure-sensitive adhesives made of halogenated flame retardants that are harmful to the environment.

Pressure-sensitive adhesive is a kind of adhesive without the aid of a solvent, heat, or other means, just applies mild pressure, and can be firmly bonded with the adhesive. Its characteristics are easy to stick, uncovered is not difficult, and it a long time the adhesive layer will not dry solid, so the pressure-sensitive adhesive is also called self-adhesive. It is because of this property of pressure-sensitive adhesive, that its products are widely used in packaging, printing, medical, home appliances, and manufacturing industries.

There are many kinds of pressure-sensitive adhesives. According to different classification standards, pressure-sensitive adhesives can be divided into various types. The common classification is according to the composition of the main material of pressure sensitive adhesive is divided into rubber series and resin series two categories, further can be divided into rubber pressure sensitive adhesive, thermoplastic elastomer pressure sensitive adhesive, acrylic ester pressure sensitive adhesive, silicone pressure sensitive adhesive and polyurethane pressure sensitive adhesive. Among them, acrylate pressure-sensitive adhesive is the hot research and development at present.

Acrylate pressure-sensitive adhesives are formed by the copolymerization of acrylate monomers and other vinyl monomers. The acrylic pressure-sensitive adhesive formula is simple, wide bonding range, good weather resistance, light resistance, excellent oil resistance, good water resistance, and no phase separation, and migration phenomenon, so it is widely used in various fields.

But now many industries need to have the flame retardant performance of pressure-sensitive adhesive, especially now electronic products battery requires strong acid and alkali resistance and flame retardant performance, and ordinary acrylic acid pressure sensitive adhesive does not have strong acid and alkali resistance and flame retardant performance, in addition to the market there are many flame retardant pressure sensitive adhesive made with halogen flame retardant agent, combustion will release toxic hydrogen halide gas, harmful to the environment and human body. Therefore, we need to provide a pressure-sensitive adhesive with strong acid and alkali resistance and flame retardant, which not only can resist strong acid and alkali but also does not have flame retardant properties.

Acrylic pressure sensitive adhesive

Acrylic polymer-like compositions have long been used as adhesive compositions, particularly in pressure-sensitive adhesive (” PSA “) compositions. They exhibit adhesion to a wide variety of surfaces, display good low-temperature properties, often produce attractive transparent adhesives, and possess excellent thermal, aging, and UV stability. Acrylic binder polymers can be obtained as organic (solvent) solutions, aqueous emulsions, and 100% solid thermoplastic systems applied as melts. Initially, the most common PSA is solvent acrylic, but market demand leads to the rapid growth of water-based acrylic, also known as emulsion acrylic adhesives. Traditionally, acrylic PSA compositions are characterized by the selection of acrylic monomers and polymerization conditions. Examples of such properties are cohesion (such as shear strength) and adhesion (such as adhesion and peel strength).

For example, acrylate monomers that reduce the glass transition temperature of acrylic polymers (e.g., butyl acrylate and 2-ethylhexyl acrylate) improve adhesion properties, while acrylate monomers and vinyl monomers that raise the glass transition temperature of acrylic polymers improve cohesion properties (e.g., methyl methacrylate, styrene, and vinyl acetate). Unfortunately, more use of one monomer leads to less of the other, so cohesion and adhesion are often inversely correlated, so an improvement in one property causes a decline in the other.

Usually, we use pure monomer synthesis emulsion acrylic PSA. Acrylate monomers that give adhesion properties usually include straight carbon chains (e.g., butyl acrylate) or single-branched carbon chains (e.g., (methyl) acrylate monomers of 2-ethylhexyl acrylate and C12-C322-alkyl alkanols). However, it is also possible to use mixtures of (methyl) acrylate alkyl monomers with carbon chains (or carbon numbers) of varying lengths and different branched carbon chains including two or more branches. Unconstrained by theory, it is believed that the diversification of carbon chain length and increased branching improves the cohesive properties of acrylic Psas (including, for example, more than a five-fold improvement in shear strength) while maintaining the adhesive properties of acrylic Psas.

Body pressure sensitive adhesive film

Pressure sensitive adhesive coating of the body is attached to the surface of the car paint by polymeric materials, so as to protect the original paint and decorate the body. It can be easily removed at any time, which is in sharp contrast to the chemical changes of the traditional glaze, coating, spray painting, and other paint surfaces. The auto-body coating is a high-performance and low-viscosity PVC film designed for auto-body coating. It has the properties of fully fitting the paint and interior surfaces of various substrates and has many advantages such as more convenient construction, flexibility, durability, chemical corrosion resistance, light permeability, and so on.

It can effectively ensure accurate, seamless, and bubble-free coating when facing the tortuous body surface in the construction process. It will not cause damage to the car paint. On the contrary, it will fully protect the original paint of the vehicle. At present, the car coating substrate is used in the market as long as there are PVC and PU two materials. PVC material car clothing film because of its cheap price, ease to use, in the mainstream position in the market, but because there are a lot of plasticizers in PVC substrate, after aging, migration to the pressure sensitive adhesive film, resulting in a sharp reduction of adhesive cohesion-layer, in the stripping of residual glue.

Plasticizers added to PVC can reduce the intermolecular chain force so that the glass transition temperature of PVC plastic, flow temperature, and the melting point of the microcrystals are reduced, plasticizer can improve the plasticity of resin, soft products, low-temperature resistance performance.

As long as there are plasticizers currently used in PVC, fatty acid esters, such as dioctyl adipate (DOA): Diiso-decyl metal hydrate (DIDA), dioctyl azelaic acid (D0Z), dioctyl sebacate (DBS), dioctyl sebacate (DOS), disco-octyl sebacate (DIOS), di-(2-methyl butyric acid) trimethylene glycol ester (3GH); Phthalates, such as dioctyl phthalate (DOP), disco-octyl phthalate (DIOP), disco-decyl phthalate (DIDP), disco-nonyl phthalate (DINP), dibutyl phthalate (DBP), diisobutyl phthalate (DIBP), butyl benzyl phthalate (BBP), Dimethyl phthalate (DMP), diethyl phthalate (DEP), dicyclohexyl phthalate (DCHP), dioctyl terephthalate (DOTP) pressure sensitive adhesive is used in various fields of daily life, different fields have different requirements for pressure sensitive adhesive.

In the field of automotive automotive clothing, the pressure sensitive adhesive requirements have excellent aging resistance, and can not produce residual glue when stripping. With appropriate peeling force, when the construction of the film, if you find that the paste is not correct, you can timely, easy to tear off the heavy paste, paste, in the bending surface, and the corner is not easy to tilt the head.

Improve the antistatic property of pressure sensitive adhesive

With the rapid development of electronic science and technology, microelectronics are becoming more and more sophisticated, and the damage caused by static electricity to electronic equipment such as touch screens, chips, and large-scale integrated circuits is more and more serious. Silicone pressure sensitive adhesive has good chemical resistance, weather resistance, heat resistance, and a wide range of use, is a good silicone pressure sensitive adhesive material that can be prepared with an antistatic effect. Using the antistatic protective film prepared by it, it is easy to derive the static electricity generated in the process of electronic materials, so as to avoid the damage of electronic materials caused by electrostatic accumulation.

How to prepare a silicone pressure sensitive adhesive with a good antistatic effect is still an urgent problem to be solved at present. In order to solve the above technical problems, the following technical solutions are provided. A method of preparation of antistatic silicone pressure sensitive adhesive, including the following steps:

step 1: take the multi-walled carbon nanotubes, modified ionic liquid, grinding 50  60 min, to join the deionized water, ultrasonic dispersion 90  120 min, by adsorption of an ionic liquid suspension of carbon nanotubes, in 65  drying under 70 ℃, carbon nanotubes by adsorption of ionic liquid;

After the hydroxylation of talc powder, the hydroxyl group on talc powder will undergo an esterification reaction with the carboxyl group on the carboxyl ionic liquid, and then graft together, which can improve the dispersion of talc in the pressure sensitive adhesive.

Meanwhile, the hydroxyl group on talc can improve the molecular polarity of organosilicon resin, improve the adhesion force of organosilicon pressure sensitive adhesive, and improve the peeling force of pressure sensitive adhesive.

(2) Ionic liquid is a substance composed of anions and ions, which can improve the antistatic performance of pressure sensitive adhesive, but the stability is not good in pressure sensitive adhesive. Multi-walled carbon nanotubes and mechanical performance are good, good electrical conductivity, but easy to reunite, modified ionic liquid adsorbed on multi-walled carbon nanotubes, solved the multi-walled carbon nanotubes not easily dispersed in the psa, control of multi-walled carbon nanotubes, modified ionic liquid mass ratio of (0. 1  0. 2): At this time, to add a large amount of multi-walled carbon nanotubes, carbon nanotubes can lap together to form a conductive path, to reduce the resistivity, improve the antistatic property of pressure sensitive adhesive.
