High-hardness impact-resisting heat-insulation foaling plastic

Abstract

The invention discloses high-hardness impact-resisting heat-insulation foaling plastic. The high-hardness impact-resisting heat-insulation foaling plastic is prepared from, by weight, 20-25 parts of polystyrene resin, 40-55 parts of polyurethane resin, 20-25 parts of phenolic resin, 10-15 parts of urea formaldehyde resin, 4-7 parts of diethylaminopropylamine DEAPA, 2-5 parts of azobisformamide AC, 0.9-1.2 parts of polydimethylsiloxane-polyoxyalkylene copolymer, 1-4 parts of talcum powder, 0.3-0.6 part of quartz powder, 1.4-1.7 parts of hollow microspheres, 1-4 parts of bentonite, 20-25 parts of diatomite, 10-13 parts of calcium carbonate, 5-8 parts of polyethylene-octene copolymer elastomer and 12-16 parts of glass fiber, wherein the polydimethylsiloxane-polyoxyalkylene copolymer is obtained by polydimethylsiloxane and polyoxyalkylene through blending modification, and the polyethylene-octene copolymer elastomer is obtained by polyethylene and octene through blending modification. Air bubbles in the high-hardness impact-resisting heat-insulation foaling plastic are even, the heat conductivity coefficient is reduced, the heat-insulation performance is improved, and the hardness and impact resistance are further greatly improved.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a high-hardness, impact-resistant, heat-insulating foamed plastic. Background technique [0002] As one of the most widely used materials, plastic is essential in daily life. Its plasticity, stability and economical practicability can bring convenience to people. Foam plastic is obtained by foam molding of plastic. Foam molding is The process of making plastics produce microporous structures. Almost all thermosetting and thermoplastic plastics can be made into foamed plastics. The products are convenient for storage and transportation, and have a wide range of applications. They can not only be used for agricultural mulch and packaging bags, but also widely used in the field of medicine. However, the existing foamed plastics have insufficient hardness, poor impact resistance, and poor heat insulation effect. Therefore, high-hardness, impact-resistant and heat-insulating foamed p...
