Problems solved by technology

The most prominent problem is that it is easy to burn, and the flame retardants used will often fail after a few years, and a large amount of toxic black smoke will be generated when burning; secondly, the service life is short, and it needs to be repaired once every 25 years, which will generate a lot of difficult-to-dispose garbage; The third is that the production and construction will pollute the environment, especially the organic thermal insulation materials and glass fibers contained in the garbage, which are not easy to fully recycle, and may repeatedly pollute the air and soil

Abstract

The invention provides a lightweight concrete energy saving insulation board, which comprises 65-75 parts of ordinary Portland cement, 30-37 parts of an admixture, 8-10 parts anti-cracking fiber, 11-14 parts of a reinforcing composite powder, 55-65 parts of water, 7.5-9.5 parts of an additive, and 6-9 parts of a foaming agent. The admixture comprises 10-12 parts of desulfurized gypsum, 8-10 parts of vermiculite powder, and 12-15 parts of petroleum, tar and shale mixed combustion circulating fluidized bed ash. The anti-cracking fiber is made from 3-4 parts of chopped carbon fiber, and 5-6 parts of chopped basalt fiber. The reinforcing composite powder consists of 3-4 parts of titanium diboride, 5-6 parts of glutinous rice and 3-4 parts of boron nitride. The additive comprises 1-1.5 parts of pine tar oil, 1.5-2 parts of ethylene glycol distearate and 5-6 parts of a polycarboxylate high performance superplasticizer. The foaming agent comprises 2-3 pars of alkyl polyglucoside, 2-3 parts of cocamidopropyl betaine and 2-3 parts of hydrogen peroxide.
