Problems solved by technology

[0002] Water-based coatings use water-soluble resins as film-forming materials. Water-based coatings use water as a solvent, which saves a lot of resources. Water-based coatings eliminate the risk of fire during construction, reduce air pollution, and are environmentally friendly. However, water-based coatings are harmful to the construction process. And the surface cleanliness of the material is high, and the dirt is easy to cause shrinkage of the coating film, so that it is not firmly combined with the substrate. With the improvement of people's living standards and the enhancement of environmental protection awareness, water-based coatings for interior walls are more and more popular. Welcome, but the water-based paints currently sold in the market are of various brands and qualities, and have poor water resistance. They dry quickly after contact with water and are prone to cracks.
[0003] The existing patent document CN 108034343 A discloses an anti-fouling water-based paint, which has good anti-fouling performance, but when used for interior walls, the combination of the water-based paint and the interior wall substrate is not firm enough, and it is easy to fall off. Patent document CN108342154 A discloses an anti-cracking water-based paint, which can effectively prevent cracks in the water-based paint, but the water-based paint has poor antifouling performance when used for interior walls, and it is difficult to remove after staining

Abstract

The invention mainly relates to the technical field of waterborne paint processing and discloses anti-fouling and crack-resistant waterborne paint for an interior wall. The paint is prepared from thefollowing raw materials: 37-39 parts of acrylic resin, 31-33 parts of alkyd resin, 15-17 parts of natural latex, 14-16 parts of hydroxypropyl methyl cellulose, 4-6 parts of modified nano-zeolite, 1.3-1.5 parts of nano-silica, 0.6-0.8 part of 3-methacryloxypropyltrimethoxysilane, 0.2-0.4 part of nano-silver, 0.11-0.13 part of graphene and 60-65 parts of deionized water. The anti-fouling and crack-resistant waterborne paint for the interior wall can be tightly bound with the interior wall, prevents fouling effectively and is bacteria-resistant and bacteriostatic, cracking caused by rapid dryingof the waterborne paint is prevented, and practicability of the waterborne paint for the interior wall is improved; the acrylic resin and the alkyd resin are mixed and then heated and stirred slowly,raw material grafting can be promoted, strength and flexibility of the waterborne paint can be improved, the waterborne paint can be tightly bound with the interior wall, and falling off is prevented.
