Problems solved by technology

Although the composite material solves the problem of poor thermal conductivity of ordinary polystyrene resin, it still has cold resistance (the embrittlement temperature is high, and the performance drops more seriously in low temperature environment), high temperature oxidation resistance (although the heat The deformation temperature is high, but it is easy to be oxidized and cracked in a high temperature environment) poor, brittle and easy to crack, and poor toughness

Abstract

The invention provides a polystyrene resin-based composite material. The polystyrene resin-based composite material comprises, by weight, 45 to 65 parts of polystyrene resin, 10 to 14 parts of chlorine ether rubber, 5 to 9 parts of uvarovite powder, 5 to 8 parts of a fire retardant, 2 to 5 parts of a light stabilizing agent, 1 to 2 parts of an antistatic agent, 2 to 7 parts of a plasticizer, 2 to 3 parts of a lubricant, 1 to 3 parts of a heat stabilizer, 2 to 5 parts of a compatilizer and 0.4 to 0.5 part of a nucleating agent. The invention further discloses a preparation method for the polystyrene resin-based composite material. The polystyrene resin-based composite material provided by the invention has good cold resistance, high temperature resistance, oxidizability and toughness.

Description

Technical field: [0001] The invention relates to a composite material, in particular to a polystyrene resin-based composite material and a preparation method thereof. Background technique: [0002] Polystyrene resin (Polystyrene, abbreviated as PS) refers to a polymer synthesized by free radical addition polymerization of styrene monomer, and is a colorless and transparent thermoplastic. Polystyrene includes ordinary polystyrene, expanded polystyrene (EPS), high impact polystyrene (HIPS) and syndiotactic polystyrene (SPS). Ordinary polystyrene resin is non-toxic, odorless, colorless transparent particles, glass-like brittle material, its products have extremely high transparency, light transmittance can reach more than 90%, good electrical insulation performance, easy to color, easy to process Good fluidity, good rigidity and good chemical corrosion resistance. Polystyrene can be widely used in the light industry market, daily decoration, lighting instructions and packagin...
