Pressure sensitive adhesive flame retardant polymer mixed with acrylic polymer

Flame retardant polymer mixed with acrylic polymer imparts flame retardant to the acrylic polymer. Generally speaking, the flame-retardant polymer is mixed with an acrylic polymer to produce a uniform composition. They are not only transparent but also elastic, wear-resistant, and self – extinguishing.

Flame retardant polymer

The commonly used allyl chloride oligomer flame retardant pressure sensitive adhesive is to add a chloride of allyl chloride oligomer to the acrylic ester. Ionized by irradiation to induce polymerization. Another common polymer-based flame retardant is vinyl chloride -2- ethylhexyl acrylate copolymer. This flame retardant is actually a copolymer of vinyl chloride and 2-ethylhexyl acrylate, in which the latter content is generally 3% to 5% of the total. This copolymer is mixed with the copolymer of MMA homopolymer or alkyl acrylate mixture to obtain a transparent, self-extinguishing uniform thermoplastic component. In practical application, a small amount of organophosphate ester can be added to increase the flame retardant effect and plasticity.

Polyacetylene benzene polymer

Polyacetylene benzene polymer is a new type of polymer flame retardant explored in recent years. Because a benzene ring containing 3 or more acetylene compounds itself is easy to polymer, the thermosetting resin can also form a copolymer with other monomers. These polymers can be cracked into carbon at high temperatures in the air, and the carbon layer formed is resistant to high temperatures and oxidation. It is predicted that these polymeric-derived carbon-carbon complexes have the potential to withstand extremely high temperatures (1000℃,1500℃, or even 2000℃) in oxidizing environments, and have the potential to be used as ablative materials in re-entry equipment for rocket missile systems and spacecraft.

This polymer is mixed with acrylates to give the acrylates excellent flame retardancy.

Linear siloxane-acetylene polymer

Linear siloxane-acetylene polymer in the field of flame retardant materials is very important, this is because the siloxane group has good thermal and oxidative stability and hydrophobicity, and the diacetylene group can carry out thermal reaction or photochemical reaction and form a toughness of conjugate network crosslinked polymer, Therefore, the resin formed by mixing this polymer with acrylates has excellent thermal oxidation stability and flame retardant.
