Problems solved by technology

However, organic insulation panels, although superior in insulation performance and light in weight, have fire hazards, and their service life is short and cannot last the same life as buildings. Secondary insulation will cause a huge economic burden.
Existing inorganic insulation boards have long service life, no fire hazards, low strength, easy hollowing, cracking, weak anchoring, and potential safety hazards of falling off in one piece

Abstract

The invention discloses a cement foamed heat insulation core material, an inorganic compound heat insulation plate, a manufacturing method and a mold. The core material is manufactured by mixing the following components in percentage by weight: 31-35% of fly ash, 49.7-62.8% of silicate cement, 0.8-1.2% of water repellent, 0.6-8% of early strength agent, 4-5% of foaming agent, 0.4-0.6% of high molecular fibers and 0.4-0.5% of composite foaming agent. Renewable resources are sufficiently utilized, and the provided inorganic compound heat insulation plate has excellent heat insulation performance, high strength, excellent breaking resistance and good sound insulation performance, is inorganic, green, low in manufacturing cost and as long as a building in service life and achieves a non-combustible level A. The inorganic compound heat insulation plate can be solidified with a concrete structure into a whole as a secondary template when a structural body is poured, and can also be used for solving the problem about external wall heat insulation and floor heat insulation without influencing the structural body.

Description

technical field [0001] The invention relates to a cement foaming thermal insulation core material, an inorganic composite thermal insulation board, a manufacturing method and a mould. Background technique [0002] Energy conservation and emission reduction is a basic national policy for my country's investment-saving society and sustainable development. At present, my country's building energy-saving wall insulation is still dominated by external wall insulation systems. The use of insulation boards, bonding, anchoring, laying reinforced mesh, and external anti-cracking mortar are the mainstream technologies. However, organic thermal insulation boards, although superior in thermal insulation performance and light in weight, have fire hazards, and their service life is too short to last as long as the building. Secondary thermal insulation will cause a huge economic burden. The existing inorganic thermal insulation board has long service life, no fire hazard, low strength,...
