Abstract

The invention discloses a foam board for a cold-resistant and high-temperature-resistant movable board house, which is composed of the following components in parts by weight: 45-55 parts of low-density polyethylene, 20-30 parts of high-density polyethylene, and asbestos powder. 20-25 parts, talc 12-15 parts, calcium carbonate 10-12 parts, soap powder 2-4 parts, glass fiber 3-5 parts, AC foaming agent 3-5 parts, tribasic lead sulfate 2- 4 parts, 22-25 parts of lightweight inorganic fillers, 1-3 parts of dispersant, 4-6 parts of azodicarbonamide, 0.5-0.8 parts of heat stabilizer, 15-20 parts of white wall slag, 40 parts of water ‑45 parts; the invention has good cold resistance and high temperature resistance effect, is conducive to environmental protection, and can effectively solve the problems of uneven board surface, thin crust thickness, low production efficiency, and low yield.

Description

technical field [0001] The invention relates to the field of building boards, in particular to a foam board for cold-resistant and high-temperature-resistant movable board houses. Background technique [0002] Foamed sheet is a new type of plastic material developed in the 1970s abroad. Due to its unique production technology, it has excellent performance and is widely used in construction, vehicles, furniture, decoration, advertising production, exhibition signs , city appearance environmental protection, tourism and other industries. Hard-crust low-foaming PVC sheet is one of the materials with excellent performance. In recent years, the production of low-foaming extruded products in my country has made considerable progress, but the scale, product variety and quality are all in line with the development of my country's chemical building materials market. The situation is not suitable, and the relationship between extrusion rate and performance needs to be further studied ...
