Abstract

The invention discloses a waterproof heat-insulation exterior wall coating and a preparation method thereof. The waterproof heat-insulation exterior wall coating comprises the following components inparts by weight: 22-42 parts of a silicone-acrylic emulsion, 5-12 parts of alumina silicate fiber, 8-15 parts of hollow glass bead, 4-9 parts of pigments and fillers, 3-7 parts of expanded vermiculite, 1.3-2.8 parts of a dispersant, 0.6-1.4 parts of a levelling agent, 1.6-3.8 parts of a film-forming auxiliary agent, and 13-18 parts of deionized water. The waterproof heat-insulation exterior wall coating has excellent waterproof heat-insulation performance, the silicone-acrylic emulsion is used as a film-forming object, and fillers such as a nano SiO2 aerogel, hollow glass bead and expanded vermiculite are cooperated, and under cooperation of a plurality of auxiliary agents, the prepared coating has good heat insulation and water resisting performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a waterproof and heat-insulating exterior wall coating and a preparation method thereof. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Additives, viscous liquids prepared with organic solvents or water. A layer of paint is often required on the outside of the wall to play a certain protective role. The exterior wall has high requirements for the paint. The existing paint often has defects such as poor waterproof and moisture-proof performance and poor flame retardancy. [0003] In China's published patent application CN102875086A, for the preparation of putty powder with strong water resistance and cohesiveness, sepiolite powder, kaolin...
