Anti-cracking water resistant heat insulation material and preparation method thereof

Abstract

The invention discloses an anti-cracking water resistant heat insulation material and a preparation method thereof. The anti-cracking water resistant heat insulation material is prepared from the following major raw materials in parts by weight: 30 to 46 parts of glazed hollow beads, 12 to 18 parts of zeolite, 11 to 15 parts of coke, 6 to 12 parts of dog bone, 4 to 8 parts of saw dust, 4 to 9 parts of epoxy resin, 3 to 7 parts of magnesium powder, 4 to 9 parts of hydroxyethyl ether cellulose, 13 to 17 parts of portland cement and 1.1 to 1.8 parts of compound penetrating agents. The obtained anti-cracking water resistant heat insulation material has the advantages that the anti-cracking and water resistant performance is good; the plastering surface has no crack; no hollowing falling exists; the tensile degree is high; the construction is easy; freezing resistance is realized; safe, fireproof and environment-friendly effects are achieved; the excellent performance of heat insulation, heat isolation and the like is realized; the heat insulation performance is stable; the integral performance is good; the wear-resistant, corrosion-resistant and radiation protection performance is obvious; a good flame retardant effect is achieved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a crack-proof and water-resistant thermal insulation material and a preparation method thereof. Background technique [0002] Insulation materials are generally materials with a thermal coefficient less than or equal to 0.2. Using good thermal insulation technology and materials in construction and industry can often get twice the result with half the effort. Statistics show that for every ton of mineral wool insulation products used in construction, one ton of oil can be saved a year. External wall insulation is a newly emerging energy-saving technology for external walls. There are various methods for exterior wall insulation, such as interior insulation of exterior walls, sandwich insulation of exterior walls, and exterior insulation of exterior walls. At present, the main external wall insulation technologies in my country are: styrene board plus thin layer pl...

AI Technical Summary

Problems solved by technology

[0005] At present, conventional wall insulation materials are prone to cracking and cracking, resulting in water seepage, which greatly reduces the thermal insulation performance of the external wall insulation system
