Example Embodiment

[0013] A polystyrene-modified heat-resistant composite plastic is prepared from the following components in parts by weight: 80 parts of polystyrene, 16 parts of thermoplastic styrene-butadiene rubber, 15 parts of phenolic resin, 6 parts of oil shale slag, and modified carbonic acid. 4 parts of calcium, 3 parts of carbon fiber, 2 parts of sodium lauryl sulfate, 0.8 part of dispersant, 0.25 part of plasticizer, 0.2 part of heat stabilizer.

[0014] Further, the dispersant is sodium hexametaphosphate, the plasticizer is citrate ester, and the heat stabilizer is lead dibasic lead phosphite.

[0015] Further, the oil shale slag is pretreated, and the oil shale slag is soaked in a 3.5% concentration stearic acid solution at 75-80° C. for 1 hour, then dried and roasted at a temperature of 250° C. After 30min, pulverize to 150 mesh.

[0016] Further, the carbon fibers are subjected to process modification treatment: adding carbon fibers to a 3 mol / L nitric acid solution and heating t

Abstract

The invention discloses polystyrene modified heat resistant composite plastic which is prepared from polystyrene, thermoplastic Styrene-butadiene rubber, phenolic resin, oil shale waste, modified calcium carbonate, carbon fibers, lauryl sodium sulfate, dispersing agents, plasticizer and heat stabilizer. The polystyrene modified heat resistant composite plastic is stable in quality and good in mechanical property and physical chemical property and has good adaptability and economy. According to the polystyrene modified heat resistant composite plastic, the modified oil shale is added, the impact strength of a composite material is improved, and the problem that conventional polystyrene is prone to stress cracking is avoided; the processed carbon fibers are added in a matched mode, the tensile strength of the composite plastic is greatly improved, and the wear rate is lowered; the processed phenolic resin is used in a matched mode, the tissue distribution of the composite plastic is optimized, comprehensive mechanical properties of the composite plastic are improved, and the application range of the composite plastic is broadened.
