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...
