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
The present invention relates to polymer emulsion type interfacial agents that the application base treatment uses and preparation method thereof.
Background technology
Product is formed: single-component (powder class); Product composition: black cement adds, a spot of redispersible latex powder, silica sand; Production technique: pour the powder in the product composition into powder stirrer, and stir.Product colour: grey or black; Constructional method: this product is added water, be uniformly dispersed, criticize being coated on the base material with batch mode of scraping with the type dispersion machine of holding in hand; Main application: exterior wall thermal insulation brick surface batch is scraped and to be played the interface together and be easy to the effect of exterior wall putty agglutinating.The product weakness: 1) poor adhesive force, can not use at the smooth surface base material.2) closure is poor.
Summary of the invention
The purpose of this invention is to provide a kind of sticking power better, polymer emulsion type interfacial agents that can better use at the smooth surface base material and that closure application base treatment is preferably used and preparation method thereof.
The objective of the invention is to realize like this; The polymer emulsion type interfacial agents that described application base treatment is used; Be two component products, form that the operating weight proportioning is 1: 1 by A component and B component; Its two component is rice white coating shape after mixing, and its concrete component of described A component and weight percent content are following:
1, Natvosol 0.1%-0.5%;
2, dispersion moisture agent 0.2%-0.9%;
3, silica powder 12%-19%;
4, vinylbenzene and acrylic ester polymerization emulsion 48%-65%;
5, sanitas 0.05%-0.35%;
