Heat preservation and insulation plastic for building material and preparation method of heat preservation and insulation plastic

Abstract

The invention discloses a heat preservation and insulation plastic for a building material. The heat preservation and insulation plastic is prepared from, by weight, 1-2 parts of sodium diacetate, 2-4 parts of pine needle meal, 3-5 parts of hollow glass microspheres, 7-10 parts of polystyrene, 110-170 parts of high-intensity polyethylene, 10-13 parts of scolecite, 0.6-1 part of N-hydroxymethyl acrylamide, 2-4 parts of hydroxy stearic acid, 3-5 parts of dispersed emulsion, 2-3 parts of antimonous oxide, 4-6 parts of Teflon, 0.4-1 part of bagasse, 7-9 parts of polypropylene adipate and 0.1-0.13 part of stannous octoate. According to the heat preservation and insulation plastic, the hollow glass beads and the polystyrene serve as filler, the scolecite modified by the sodium diacetate and the pine needle meal is added, a uniform microporous network can be formed in the plastic, the heat preservation and insulation performance of a finished plastic is effectively improved, and the heat preservation and insulation plastic is particularly suitable for being used as the building material in a cold area.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a thermal insulation plastic for building materials and a preparation method thereof. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It is commonly known as plastic or resin. It can freely change its composition and shape. Composed of additives such as pigments and pigments, most plastics are light in weight, chemically stable, and will not rust; they have good impact resistance; they have good transparency and wear resistance; they have good insulation and low thermal conductivity; general formability, Good colorability and low processing cost; however, there are many common shortcomings in plastic products at present: most plastics have poor heat resistance, high thermal expansion rate, and are easy to burn; poor dimensional stability and easy deformation; Bri...
