Methods for preparing flame retardant materials

Since material flame retardants do not require further flame retardant treatment, the following information is about additive flame retardants. Flammable materials can generally include thermoplastic resin, thermosetting resin, rubber, paint, fiber (natural fiber and artificial fiber), wood, etc. The above inflammable data can be modified into flame retardant data by the following methods.
(1) Thermoplastic resin Thermoplastic polyester resin contains many polyolefin, polyester, polyamide, such as polyethylene, polypropylene, polystyrene, ABS(acrylonitrile butadiene styrene copolymer), polyethylene terephthalate (PET), polybutyl terephthalate (PBT), polycarbonate (PC), nylon 6 and nylon 66. The above information and the corresponding flame retardant additives in the screw extruder through melting blending extrusion granulation, made of flame retardant granule, the end of flame retardant modification. But the general flame retardant additives have specific, that is, a specific flame retardant acting on a kind of resin. There are few types of flame retardants that can be widely used, so they generally need to be carefully selected, tested and combined.
(2) thermosetting resin Thermosetting resin includes epoxy resin, phenolic resin, polyurethane, unsaturated polyester resin, etc. This kind of resin needs to be used in multi-component blending, so. Flame retardants can be added simultaneously and mixed evenly by quick mixing. After the mixing is finished, the curing reaction is carried out at a certain temperature, and the thermosetting resin material with flame retardant function can be formed after the curing is finished.
(3) Rubber rubber can be used as wire and cable material, conveyor belt material, etc. Fire retardant request is very high. The preparation of flame retardant rubber is by blending raw rubber, flame retardant agent and various additives, and then plasticizing, blending, vulcanization after the preparation of flame retardant rubber data.
(4) Paint coating is also composed of a variety of components blend. Therefore, when used, the general flame retardant and its composite components and components of the coating are mixed to form the coating, and then coated on the surface of steel structure or wood structure and other materials to form the flame retardant coating.
