AI Technical Summary

Technical Problem

The wall insulation coatings of existing buildings have poor thermal insulation effect, high water absorption, poor weather resistance, low strength in the later stage of the product, and cannot achieve both good thermal insulation performance and water resistance and weather resistance.

Method used

Use 40-50% film-forming agent, 10-20% titanium dioxide, 4-10% hollow glass beads, 5-7.5% filler, 3-6% dispersant, 1-3% wetting agent, 1.6-4.0% film forming Additives, 0.1-0.2% cellulose, 0.1-0.5% thickener, 0.2-0.5% defoaming agent and the balance water, combined with hollow glass beads and rutile nanometer titanium dioxide, form an efficient thermal insulation coating.

Benefits of technology

It achieves excellent thermal insulation effect and excellent weather resistance, reduces the amount of film-forming agent, improves the leveling and smoothness of the coating, and has environmentally friendly and healthy performance.

Abstract

The invention belongs to the technical field of architectural coating and particularly relates to an elastic thermal insulating coating. The elastic thermal insulating coating comprises the following components by weight percent: 40-50% of film forming agent, 10-20% of titanium dioxide, 4-10% of hollow glass bead, 5-7.5% of filler, 3-6% of dispersing agent, 1-3% of wetting agent, 1.6-4.0% of coalescing agent, 0.1-0.2% of cellulose, 0.1-0.5% of thickening agent, 0.2-0.5% of antifoaming agent and the balance of water. According to the technical scheme, all the materials are environment-friendly, and excellent thermal insulating effect and weather resistance are achieved due to the adoption of the hollow glass bead and rutile-type nanometer titanium dioxide. The hollow glass bead coating has a broad market space.
