Problems solved by technology

[0005] For this reason, the technical problem to be solved by the present invention is that in the prior art, the thermal insulation effect of the exterior wall thermal insulation coating is not ideal, and the performances such as weather resistance, water resistance and alkali resistance, erosion resistance, elasticity, and stability are not good, which is harmful to buildings. Insulation and protection are poor, and the decoration cost is high, so a thermal insulation functional coating for exterior walls with high thermal insulation effect and excellent performance is proposed

Abstract

The invention discloses a thermal insulation functional coating for exterior walls. The coating comprises the following components, by weight, 100-360 parts of deionized water, 0.5-1 part of cellulose, 0.3-1.7 parts of a wetting agent, 0.4-1.6 parts of a multifunctional additive, 3-13 parts of a dispersant, 1-3 parts of an antifoaming agent, 8-32 parts of an antifreezing agent, 8-20 parts of a coalescing agent, 100-400 parts of a colouring agent, 20-80 parts of a filler, 40-260 parts of nano micro-beads, 100-460 parts of a styrene-acrylic emulsion, 0.7-3.3 parts of a preservative for coatings, 30-90 parts of a thickening agent and 0.5-1.5 parts of a pH regulator. The coating has excellent thermal insulation performance, can maintain more than 90% of heat not to be lost from objects such as buildings, and also has good properties such as low temperature resistance, temperature alternating resistance, water resistance, alkali resistance, scrub resistance and stain resistance, etc. The coating is a functional coating with functionality and decorativeness.

Description

technical field [0001] The invention belongs to the field of coatings, and relates to an exterior wall coating, in particular to a heat-insulating and heat-preserving functional coating for exterior walls. Background technique [0002] Coatings are generally viscous liquid or powdery substances, which can be applied to the surface of objects by different construction techniques. After drying, they can form a solid film with firm adhesion, certain strength, and continuity, and endow the coated object with protection, beautification and other functions. The expected effect, the exterior wall paint painted on the exterior of the building has excellent properties such as anti-ultraviolet radiation, water resistance, and self-cleaning, and is widely used in building exterior decoration to replace traditional decorative materials such as ceramic tiles, mosaics, and marble. [0003] As more and more attention is paid to the issue of building energy conservation, the building exteri...
