Grout coating and preparation method thereof

Abstract

The invention belongs to the technical field of coatings, and particularly relates to a grout coating. The grout coating comprises an emulsion and a surface-active agent, wherein the emulsion is a 65% vinyl acetate-acrylic emulsion, and the surface-active agent is sorbitol anhydride monolaurate. The grout coating can improve the scuff resistance obviously, can adopt a common cutter to polish, and has the advantages that the grout coating is high in gloss stability, and convenient to use, and is not required to be prepared on site when the grout coating is used.

Description

technical field

[0001] The invention belongs to the technical field of coatings, and in particular relates to a grout coating and a preparation method thereof. Background technique

[0002] The grout-type coatings on the domestic market are gradually being accepted by consumers due to their high ornamental value and special textures, especially the fancy texture coatings that can be polished into a mirror effect are widely used in the coating of home background walls, while the domestic market Such products sold are mainly imported from Italy and other countries, which are expensive and have extremely strict requirements on stainless steel tools for construction; while mainstream products in the domestic market mostly use kaolin as the main material that can be polished. The proportion is so large that the PVC value of the formula is >70%, so there are the following problems:

[0003] 1. Water resistance, poor scrub resistance;

[0004] 2. A high-chromium stainless stee...

Examples

Embodiment

[0065] Element percentage% water 20 Cellulose 2 2-Amino-2-methyl-1-propanol 0.5 Dispersant 1 Surfactant 0.6 Defoamer 1 talcum powder 15 light calcium 15 Washed Kaolin 5 Titanium dioxide 5 wax powder 11 Ethylene glycol 1 Antiseptics 0.6 lotion 15 lauryl alcohol ester 0.5 leveling agent 0.5 thickener 5.3

[0066] Method: Put the formula amount of water in the disperser, set the speed at 800 rpm, slowly add cellulose, pre-dissolve for 5 minutes, add pH regulator, dissolve until transparent and free of particles, then add dispersant and defoamer , Surfactant, stir for 3 minutes, then add talcum powder, kaolin, titanium dioxide, wax powder in turn, adjust the speed of the disperser to 4500 rpm, disperse at high speed for 15 minutes, check the fineness, after the fineness is ≤ 50μm Adjust the rotation speed to 1000 rpm, slowly add other ingredients in the formula one by ...
