Abstract

The invention relates to the technical field of a heat insulation material, in particular to a light-weight heat insulation plate prepared from waste and old glass. The heat insulation plate is prepared from the following raw materials of cement, high-intensity gypsum, polystyrene foam, perlite, glass micro beads, sodium silicate water glass, chopped fiber, water, retarding agents and foaming agents, wherein the glass micro beads are toughened hollow micro beads produced from waste and old glass; the used sodium silicate water glass has the modulus being 1.0 to 1.4 and the Baume degree being 45 to 50 degree Be; the chopped fiber is chopped polypropylene fiber; the length of the fiber is 13 to 15 mm; the retarding agents are one kind of protein type retarding agents special for sodium polyphosphate, sodium hexametaphosphate and gypsum; the foaming agents select oxydol. The heat insulation plate ensures the heat insulation and thermal isolation performance; meanwhile, the density of theheat insulation plate is greatly reduced, so that the heat insulation plate has lower transportation cost and construction difficulty. The glass waste materials are used; the advantage of better greeneffect and environment protection are realized.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a lightweight thermal insulation board prepared from waste glass. Background technique [0002] Thermal insulation board is a kind of building material used in building thermal insulation engineering construction. Compared with ordinary building structural materials, thermal insulation board has better thermal insulation performance, and can play a good role in thermal insulation in the building interior, thereby reducing the energy-saving characteristics of the building. , to reduce the energy consumption of temperature control equipment such as air conditioners and heating; when the insulation board is used for exterior wall construction, it can also improve the waterproof and moisture-proof performance of the building. [0003] Conventional insulation boards include XPS insulation boards, polyurethane insulation boards, cement foam insulation boards, expan...
