Solar phase change heat storage fireproof and waterproof building insulation material

Abstract

The invention relates to a fireproof and waterproof heat insulation construction material of solar energy phase transition heat accumulation, which has the following technical essentials: sequentiallyadding a certain amount of phase transition heat accumulation and heat insulation material, fly ash, light expanded vermiculite powder or light calcium powder, cement reinforcing agent and calcium oxide into a mixing trough; evenly mixing the materials by stirring at normal temperature; then, keeping stirring and sequentially adding common portland cement, an impervious waterproof agent, fatty acid zinc or fatty acid calcium as a hydrophobing agent, dihydrocalcite and ferrous sulfate or ammonia chloride as a thickening agent; fully mixing the materials evenly by cyclone separation; and packing the mixture to obtain a finished product. The heat insulation construction material of the invention has good effects of heat insulation, heat accumulation and energy saving, light volume weight (350-550 kilograms / cubic meter), large density, high strength and small heat transfer coefficient; and after freezing and thawing tests for 60 times and circulation from 20 DEG C to -40 DEG C, the heat insulation construction material has no abnormality and can meet the energy saving index of 65%. The fly ash which is a serious public nuisance is fully utilized as a renewable resource to produce theenvironment-friendly heat insulation construction material.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a solar phase change thermal storage fireproof and waterproof building thermal insulation material. Background technique [0002] As everyone knows, in the construction process of traditional buildings and one-story houses, an antifreeze layer (such as some light materials) will be set on the structural roof, and then the waterproof layer of so-called "three sticky and four oily" is laid. Because "three sticky and four oils" are most prone to aging and short life under the change of temperature difference in four seasons, frequent maintenance is required, and traditional lightweight materials are not only costly, but also have poor thermal insulation effect. With the continuous development of science and technology and the continuous progress of society, people pay more and more attention to the energy-saving, environmental protection and heat preser...

Although benzene panels will burn at a certain temperature, and will release a large amount of toxic and harmful gases during the combustion process, in order to save energy, because benzene panels do not burn at low temperatures, they are used in large quantities under the effect of fluke. So far, there are indeed some fires caused by benzene panels, which have brought huge economic losses to people's lives and production.
