Water-thinned middle layer paint for outer wall

Abstract

The water-thinned mid layer silicide or fluoride modified polymer paint is compounded with polymer emulsion, stuffing, pigment, assistant and water in certain weight proportion. It has high alkali resistance and weather resistance, excellent permeability and filling property, and is suitable for various, including old or new concrete or cement, outer wall or outer wall old coating. Its use can make the coating plumpy and colorful and avoid pinhole and microcrack in the finish layer.

Description

Technical field: [0001] The invention relates to a middle-layer slurry for decorative walls, in particular to a silicon-fluorine modified polymer middle-layer slurry suitable for water-based exterior walls. Background technique: [0002] At present, during the use of various decorative wall coatings, the inevitable small pinholes in the cement base surface often cause a large number of pinholes in the surface coating, causing the coating to crack, fall off and separate from other coatings. The phenomenon of stripping occurs, which greatly affects the appearance, and at the same time, causes financial and material losses to people. Invention content: [0003] The purpose of the present invention is to provide a kind of middle layer slurry suitable for various new and old concrete, cement wall or old coating wall with good alkali resistance, good weather resistance, good air permeability and filling ability. . The slurry can effectively improve the fullness and coloring th...
