Embodiment approach 1

[0048] To decorate the wall, after scraping the putty, apply the interface agent after polishing and smoothing, and then paint the topcoat (or diatom mud construction, wallpaper paving). Or apply the interface agent after scraping the primer and then apply the topcoat and other multi-layer brushing processes. The high-performance paste interface primer two-in-one coating proposed in this embodiment improves the performance of the high-performance paste interface primer two-in-one coating through the use of hydroxyethyl cellulose, modified silicone acrylic copolymer emulsion and inorganic components. Excellent adhesion can be used as interface agent and primer, and because it has the function of putty filling at the same time. Through the combination of the following components, the adhesion will not be damaged by the components of heavy calcium, bentonite, sand and black paste, which are mainly composed of hydroxyethyl cellulose, modified silicone acrylic copolymer emulsion an...

Embodiment approach 2

[0094] This embodiment also provides a method for preparing a high-performance paste interface primer two-in-one coating, which includes the following steps:

[0095] S1 Add water into the dispersion tank, add 0.3-0.5 parts of hydroxyethyl cellulose and AMP-95 in sequence at a speed of 200-800r / min, and stir for 5-10 minutes;

[0096] S2 Increase the rotation speed to 1000-1500r / min, add thixotropic lubricant and bentonite in turn, stir for 2-4 minutes, then add dispersant and defoamer in turn, and stir for 2-4 minutes;

[0097] S3 Increase the rotation speed to 1500-2500r / min, then add titanium dioxide, heavy calcium, and sand in sequence, and stir for 10-15 minutes;

[0098] S4 Reduce the speed to 800-1500r / min, add 40-50 parts of emulsion, stir for 1-3 minutes, then add film-forming aids, ethylene glycol, black paste, anti-corrosion and anti-fungal agents and thickeners and stir evenly to obtain wall paint.

[0099] In this embodiment, first mix AMP-95, water and hydroxye...

Abstract

The invention relates to high-performance paste interface primer two-in-one coating. The coating comprises the following components in parts by weight: 10 to 12 parts of water, 0.1 to 0.3 part of a thixotropic lubricant, 40 to 50 parts of a modified silicone acrylic emulsion, 0.3 to 0.5 part of bentonite, 0.3 to 0.5 part of a dispersing agent, 11 to 15 parts of coarse whiting, 25 to 27 parts of sand, 0.05 to 0.1 part of black paste, 0.3 to 0.5 part of titanium dioxide, 0.3 to 0.5 part of hydroxyethyl cellulose, 0.8 to 1.2 parts of a film forming aid, 0.3 to 0.5 part of ethylene glycol, 0.1 to0.3 part of AMP-95, 0.3 to 0.5 part of a defoaming agent, 0.2 to 0.3 part of a thickening agent, and 0.2 to 0.4 part of an antiseptic and anti-mildew agent. The high-performance pasty interface primertwo-in-one coating has excellent adhesion strength, the tensile bonding strength is 1.2 MPa, the coating can replace an interface agent and primer to be used, the filling efficiency is high, and thecoating can replace putty to be used as a leveling material.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a two-in-one paste interface primer with high performance and a preparation method thereof. Background technique [0002] As people's pursuit of a healthy and clean ecological living environment becomes stronger and stronger, they pay more and more attention to high-performance products, and they are more and more worried about the market where construction costs are rising. [0003] A primer is a paint that is applied directly to the surface of an object as a solid base for the topcoat. It is required to adhere firmly on the object surface to increase the adhesion of the upper coating and improve the decorativeness of the top coating. According to the coating requirements, it can be divided into primer primer, secondary primer and so on. [0004] Putty (filling mud) is a kind of decorative material for leveling the surface of the wall. It is a thick paste paint ...
