Heat preservation waterproof coating

Abstract

The invention relates to the field of coatings, and in particular relates to a heat preservation waterproof coating which is applicable to heat preservation of buildings. The coating mainly comprises the heat preservation ingredients and waterproof ingredients. The coating is characterized in that the heat preservation ingredients comprise 20-30g of nano ceramic hollow cenosphere, 15-20g of silicon-aluminum fiber, 1-35g of polyacrylic acid, 0.1-0.2g of flatting agents, 0.1-0.2g of defoaming agents, and 5-10g of titanium dioxide; the waterproof ingredients comprise 10-20g of isocyanate, 2-5g of polyether, 0.5-1g of catalyst, 0.5-1g of catalyst and 0.2-0.5g of dispersing agents; and the balance of 100g of kaolin; and the ingredients are prepared in weight calculation. The coating is good in filming effect, strong in adaptive capacity to the substrate deformation, has good thermal insulating, heat preservation and waterproof performance, and is a novel multifunctional coating.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a thermal insulation and waterproof coating suitable for building thermal insulation. Background technique [0002] Energy saving has become an important direction of social development, and how to improve the thermal insulation performance of buildings has become an important solution to saving building energy consumption. At present, most of the coatings used for building thermal insulation have poor weather resistance. When the external temperature changes greatly, the coating film will crack and the thermal insulation effect is not good. At the same time, they do not have the functions of waterproofing and fire prevention. Contents of the invention [0003] In view of the defects in the prior art, the object of the present invention is to provide a thermal insulation coating which has excellent heat insulation effect and waterproof effect. [0004] For realizing the above object, t...
