Description

technical field [0001] The invention relates to a building material, in particular to a thermal insulation material. Background technique [0002] Magnesium oxychloride cementitious material was invented by the Swedish Sorel in 1867. It has many properties superior to Portland cement, such as: no need for wet curing, high strength, fast hardening, elasticity, good surface gloss, fire prevention , heat insulation, sound insulation, low heat of reaction, adjustable condensation, easy molding, in addition, it also has the characteristics of corrosion resistance of solvents, salts and other substances. However, there are still defects and deficiencies such as poor water resistance, easy deformation, moisture absorption, and brine reversion in various products made of it as a gelling material for more than one hundred years. In addition, the solid-liquid phase multi-component packaging has disadvantages such as inconvenience in engineering application. Contents of the inventio...
