Problems solved by technology

[0003] At present, more than 90% of the water-in-water colorful paints on the market are used for water-in-water products on the exterior walls of buildings, and 10% of the water-in-water colorful paints are used for interior walls. The water-in-water art paint brand occupies; if the water-in-water products for exterior walls are used indoors, because the water-in-water products for exterior walls contain volatile substances, they do not meet the relevant industry regulations for interior wall coatings, so there is a defect that the release of harmful substances exceeds the standard ; and foreign water-in-water multi-color paint products are expensive, and the shipping period is as long as 3-4 months. Domestic construction personnel are immature in controlling the construction techniques of foreign products, which affects the use effect of the entire product, completely loses the artistic effect, and makes the product more effective. discount

Abstract

The invention belongs to the technical field of coating materials, and discloses a high-shear-resistant brushing type thick slurry water-in-water coating material, a preparation method and an application thereof. The high-shear-resistant brushing thick slurry water-in-water coating material comprises a base paint, a crosslinking protective agent solution, a continuous phase and an associative thickener, wherein the mass ratio of the base paint, the crosslinking protective agent solution, the continuous phase and the associative thickener is 4: 2: 4: 0.2-0.3. The material has the advantages that the prepared high-shear-resistant brushing type thick slurry water-in-water coating material is resistant to high shear in the granulation process by utilizing the cross-linking reaction characteristics among nano materials, namely the process is carried out at any rotation speed of 200-1400 r / min; and the coating material has the advantages of simple process, good and full color point toughness, no color cross-linking after repeated brushing, no color mixing, mass production, good continuity and long storage stability period.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a high-shear-resistant brushing type thick build water-in-water coating, a preparation method and an application thereof. Background technique [0002] In 2010, the R&D of water-in-water multi-color coatings started in our country, and manufacturers have sprung up like mushrooms everywhere, emerging in endlessly. Water-in-water multi-color paint products have the advantages of light weight, energy saving, and low cost, and are rapidly replacing natural granite stones in the use of building exterior walls. Especially in Decree No. 143 of the Ministry of Construction on Civil Building Energy Conservation Management Regulations, the market for water-in-water multi-color coating products has become extremely hot after the strict mandatory regulations on civil building energy conservation in my country. However, there are many defects in the preparation process of the ex...
