Abstract

The invention belongs to the field of thermal insulation coatings and in particular relates to a waterproof crack-resistant external wall thermal insulation coating and a preparation method thereof. The waterproof crack-resistant external wall thermal insulation coating is prepared from the following components: 30-60 parts of film-forming resin emulsion, 20-30 parts of hollow glass beads, 5-10 parts of expanded perlite, 5-8 parts of sepiolite powder, 6-8 parts of talcum powder, 5-10 parts of mica powder, 6-8 parts of kaolin, 15-20 parts of titanium dioxide, 5-10 parts of wood fibers, 4-6 parts of foamed fibers, 10-30 parts of sodium silicate, 3-5 parts of organosilicone, 1-2 parts of methylcellulose, 2-4 parts of coalescing agents, 1-2 parts of an antifoaming agent and a proper amount of water. The coating disclosed by the invention is good in thermal insulation effect and high in bonding strength and has water resistance and crack resistance, and a waterproof layer and a protective layer are not needed.

Description

technical field [0001] The invention belongs to the field of thermal insulation coatings, in particular to a waterproof and crack-resistant thermal insulation coating and a preparation method thereof. Background technique [0002] Thermal insulation coatings for exterior walls can achieve good thermal insulation effects only by simple brushing or spraying, and have both decorative and protective functions. Strong and many other advantages, the market demand is huge. At present, the most widely used is the barrier type heat insulation coating. The raw materials of the barrier type heat insulation coating are easy to obtain, the production equipment is simple, the investment is small, and the output is large; the construction is convenient, and it is suitable for the insulation of special-shaped bodies such as elbow valves and rotating spheres. Construction, heat pipes and equipment can be constructed without stopping. The disadvantages are that it has poor effect on reducing...
