2. Need to brush back and forth with a hard brush
[0005] The disadvantages of traditional anti-contamination products for interior and exterior walls are: 1. Use a large amount of detergent, which will pollute the water environment; 2. Using brushes and other cleaning tools to scrub the wall surface will scratch the high-grade wall surface and make the surface rough Unevenness; partial bright spots, inconsistent gloss on the surface of the paint film
This is mainly because the hardness of the paint film of general interior wall products is not high, the product formula PVC (pigment volume concentration) is too high and the paint film requires a matte effect.
[0007] In summary, this area lacks a water-based wall coating with dual effects of hydrophobic and oleophobic, and strong antifouling ability

Abstract

The invention provides a water-based paint composition. The water-based paint composition comprises the following components in parts by weight: 30-50 parts of film-forming substances, 26-40 parts of pigment filler, 0.3-0.5 part of HASE hydrophobic dispersing agent auxiliaries, 1.0-2.0 part of water-based fine oxidized polyethlene wax emulsion, 0.3-1.0 part of fluorine-containing surfactant, 1.0-2.0 parts of cosolvent, 1.0-2.0 parts of coalescing agents, 2.0-3.0 parts of other auxiliaries, and acceptable amount of water. Pigment volume concentration of the water-based paint composition is 30%-50%. A paint film formed by the paint composition is better in water-oil amphiphobic effect, beneficial to improving quality of an interior-wall paint product; meanwhile, a novel application field is developed, high environment-friendly requirements are combined with high-quality anti-staining characteristic, so that the product can serve for the interior decoration market better.

Description

technical field [0001] The invention relates to a water-based paint composition and a preparation method thereof, in particular to a water-based paint composition with double effects of hydrophobicity and oleophobicity and high antifouling performance and a preparation method thereof. Background technique [0002] Coating is a kind of chemical product with convenient construction, low price, obvious effect and high added value rate. It can not only decorate the surface of buildings, ships, machinery, etc., but also has the function of preventing the surface from rusting and prolonging the service life. A fine chemical product with strong specialization and strong functionality. [0003] With the passage of time, the interior and exterior wall coatings are prone to varying degrees of pollution, abrasion, peeling off, fading and aging of the walls, affecting the appearance of the city. Therefore, it is very important to prevent the penetration of stains on the wall and prolo...
