Abstract

The invention discloses a polymer emulsion interface agent for base layer coating treatment and a preparation method thereof. The polymer emulsion interface agent for base layer coating treatment comprises a component A and a component B. In use, the component A and the component B are mixed according to a weight ratio of 1: 1. The mixture of the component A and the component B is white paint. The component A comprises 0.1 to 0.5% of hydroxyethylcellulose, 0.2 to 0.9% of a dispersing wetting agent, 12 to 19% of quartz powder, 48 to 65% of styrene-acrylic acid ester polymer emulsion, 0.05 to 0.35% of an antiseptic, 0.01 to 0.2% of a mildew inhibitor, 0.05 to 0.25% of a multifunctional auxiliary agent, 0.05 to 0.55% of a thickening agent, 0.1 to 0.5% of an antifoaming agent, 0.2 to 0.7% of a film forming auxiliary agent and 18 to 35% of water. The component B comprises 20 to 38% of wollastonite powder, 15 to 35% of quartz powder and 38 to 55% of quartz sand. Through combining the component A and the component B according to a ratio, the polymer emulsion interface agent for base layer coating treatment has the characteristics of good cohesion and adhesion, high bonding intensity, good closeness, rough surface layer and good adhesiveness with putty.

Description

Technical field [0001] The invention relates to a polymer emulsion type interface agent for coating base layer treatment and a preparation method thereof. Background technique [0002] Product composition: single-component (powder); product composition: black cement, a small amount of redispersible latex powder, quartz sand; production process: pour the powder in the product composition into a dry powder mixer and mix it evenly. Product color: gray or black; construction method: add water to the product, disperse the product evenly with a hand-held disperser, and apply batch scraping to the substrate; main purpose: the surface of the external wall insulation brick is scraped together to form an interface Easy to bond external wall putty. Product weaknesses: 1) Poor adhesion, so it cannot be used on smooth surface substrates. 2) Poor sealing. Summary of the invention [0003] The purpose of the present invention is to provide a polymer emulsion type interface agent for coating b...
