Problems solved by technology

[0002] At present, in construction and painting engineering, intermediate paint is commonly used. Although it can meet the general requirements of use, it does not have the functions of anti-cracking and waterproofing.
For example, the wall of a building has just been painted, and not long after, the wall cracks and the wall leaks, which seriously affects the paint coating effect.
[0003] With the vigorous development of the construction and painting industry, the preparation method of the original intermediate paint is slow, the construction period is long, the anti-cracking and waterproof functions are poor, and the cost is high

Abstract

The invention discloses an anti-cracking water-resistant intermediate paint preparation method and a product prepared by the method. The elastic emulsion used in the product is Tianba 2000, which has excellent water resistance, flexibility, alkali resistance and percentage of elongation. Assistants are common assistants for construction paints; and fillers are barium sulfate, talcum powder and coarse whiting powder, and the coarse fillers can enhance the physical and chemical properties of the coated film and lower the cost. The method disclosed by the invention has the advantages of simple preparation technique and high production efficiency, and is easy to implement. The anti-cracking water-resistant intermediate paint product disclosed by the invention has the advantages of favorable flexibility, strong cracking resistance (can bridge a 0.5-3mm crack), favorable water resistance, high binding firmness, favorable comprehensive properties, high temperature tolerance and high weather resistance, effectively solves the phenomena of cracking and water leakage in the walling, and ensures the walling to have neat and elegant appearance; and besides, the construction process is simple, greatly shortens the construction period, enhances the construction efficiency, requires low cost, and is beneficial to wide popularization.
