Many flame-retardant pressure-sensitive adhesives made of halogenated flame retardants that are harmful to the environment

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.
