Abstract

A modified styrene functional material with a solar reflection spectrum and a preparation method thereof are disclosed. The material has a plurality of functions, such as environmental friendliness, excellent mechanical properties, flame retardation and stable ultraviolet radiation resistance, and especially has excellent solar reflection performance so that the material has a significant coolingfunction. If a flame retardant-synergist consisting of 1,2-bis(pentabromophenyl) ethane and antimonous oxide is added in a styrene resin system and titanium dioxide is added at the same time, flame retardation performance is ensured, and solar spectrum reflectance and cooling performance of the styrene resin can be further improved. A new use of 1,2-bis(pentabromophenyl) ethane or antimonous oxideor a combination thereof is unexpectedly discovered, and application of 1,2-bis(pentabromophenyl) ethane, antimonous oxide or a combination thereof in improvement of solar spectrum reflectance and cooling performance of styrene resin materials is provided.

Description

technical field [0001] The invention relates to a functional polymer material and a preparation method thereof, more specifically to a modified styrene functional material with reflective solar spectrum and a preparation method thereof. Background technique [0002] Styrene resins are polymers obtained by homopolymerization of styrene as a monomer or copolymerization of styrene with other unsaturated monomers, usually including styrene homopolymers and styrene A general term for a large class of resins including copolymers as the main component. The main commercialized styrenic resins in the industry include polystyrene resin (PS), high impact polystyrene resin (HIPS), styrene-acrylonitrile copolymer (SAN), methacrylate-styrene copolymer (MS), acrylonitrile-butadiene-styrene copolymer (ABS), methacrylate-butadiene-styrene copolymer (MBS), acrylonitrile-acrylate-styrene copolymer (ASA) resin Wait. Styrene resins have good mechanical properties (higher tensile strength, imp...
