Abstract

The invention discloses an organic composite material. The organic composite material is prepared from the following raw materials in parts by weight: 100-130 parts of polystyrene, 50-70 parts of polyethylene glycol, 25-40 parts of ethylene-acrylic acid copolymers, 8-12 parts of carbon fibers, 0.5-2 parts of a coupling agent, 5-10 parts of azodicarbonamide, 2-5 parts of graphite particles, and 2-3parts of octadecanamide. All the raw materials are evenly mixed under the heating condition, and then the organic composite material with the heat-insulating property is obtained.

Description

technical field [0001] The invention relates to the technical field of composite material production, and more specifically relates to an organic composite material and a synthesis method thereof. Background technique [0002] Polystyrene (Polystyrene, abbreviated as PS) refers to a polymer synthesized by free radical addition polymerization of styrene monomer. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100°C. It is easy to process and shape, and has the advantages of transparency, cheapness, rigidity, insulation, and good printability. It is widely used in the light industry market. In terms of decoration, lighting instructions and packaging, it is also a good insulating material and heat insulation material in terms of electricity. It can be used to make various instrument casings, lampshades, optical and chemical instrument parts, transparent films, capacitor dielectric layers, etc. [0003] In addition to being widely...
