High-strength waterproof thermal-insulation coating for thermal-insulation board

Abstract

The invention discloses a high-strength waterproof thermal- insulation coating for a thermal- insulation board. The coating is prepared from the following raw materials: pyrophyllite powder, basalt fibers, spodumene powder, a flame retardant, aluminum silicate, zirconium oxide, a penetrating agent, dolomite powder, glass beads, a regulator, a stabilizer, yttrium oxide, high-temperature-resistant resin, cellulose, a polyvinyl formal aqueous solution, ceramic hollow beads, konjac glucomannan and a thickener. The thermal- insulation coating disclosed by the invention is based on thermal insulation lightweight aggregates glass beads, ceramic beads and the like; the high-strength waterproof thermal-insulation coating for the thermal-insulation board is prepared by compounding resin emulsion, afunctional filler and the like; the thermal-insulation coating has the advantages of very low heat conductivity coefficient, higher emissivity, excellent heat insulation and heat preservation functions, no cracking and strong decorative feeling, so that the thermal-insulation coating effectively blocks the heat transfer, radiates back the heat attached to the surface of the thermal-insulation coating at higher emissivity, and lowers the heat loss.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation coatings, in particular to a high-strength waterproof and thermal insulation coating for thermal insulation boards. Background technique [0002] With the in-depth development of architectural coatings, the concept of building external thermal insulation coatings and coating technology quality has become increasingly popular. In order to improve the quality of coating coatings for external thermal insulation finishes, in addition to high-quality coating products, there must be high-quality coatings. The best quality supporting products and standardized construction technology are suitable for it, and one link is indispensable, otherwise there will be various quality problems of external thermal insulation projects. However, people are very concerned about the performance, quality and price of external thermal insulation coatings. The ideal decorative effect of the thermal insulation co...

AI Technical Summary

Problems solved by technology

At present, most civil thermal insulation coatings use organic or polymer materials as the matrix, which have good waterproof performance but poor durability. They are easy to age under sunlight and cause chalking, which causes the thermal insulation coating to peel off and lose its thermal insulation ability. Therefore, it is not suitable as a thermal insulation coating. Board surface insulation coating

However, the thermal insulation coating using inorganic materials as the matrix has strong resistance to ultraviolet light, but its waterproof performance is poor, and it cannot withstand the rain on the surface of the thermal insulation board.
