Abstract

The invention discloses a water-based composite exterior wall coating and a preparing method thereof. The coating includes the following components in mass percentage: 8-11% of water, 17-22% of silica sol emulsion, 18-21% of GHNK high temperature resistant emulsion, 10-15% of 930 rutile titanium dioxide, 5-8% of alcohol ester-12, 5-8% of calcite powder, 5-8% of wollastonite powder, 5-7% of silicon dioxide powder, 3-6% of mica powder, 5-8% of talcum powder, 0.3-0.9% of a GH5050 dispersing agent, 1.0-1.6% of a flatting agent 2, 0.1-0.5% of a 102 thickening agent, 0.1-0.2% of a 981 antiseptic agent and 0.1-0.2% of a 202 defoaming agent. The coating provided by the invention has the advantages of excellent high temperature resistance, weather resistance, water resistance, strong adhesive force, scrubbing resistance, artificial aging resistance and the like, meets the requirements of and is far superior to the national standards of GB/T9755-2001 and GB18583-2001, is a novel environment-friendly product for upgrading the building emulsion, and has excellent application prospect.

Description

technical field [0001] The invention relates to architectural paint technology, in particular to a novel water-based high-performance composite exterior wall paint and a preparation method thereof. Background technique [0002] Exterior wall coatings are mainly used to decorate and protect the exterior walls of buildings, so that the appearance of buildings is neat and beautiful, so as to achieve the purpose of beautifying the urban environment. decorative and protective effects. The exterior wall decoration is directly exposed to nature and is subjected to wind, rain, and sun exposure. Therefore, the coating is required to have water resistance, color retention, pollution resistance, aging resistance, and good adhesion. It also has good freeze-thaw resistance and film-forming properties. Features such as low temperature. In recent years, the research on exterior wall coatings has achieved certain results, but there are still many problems to be solved, such as high temper...
