Problems solved by technology

[0002] There are various types of traditional latex paints on the market. Traditional latex paints have poor antifouling effect, poor abrasion resistance, poor aging resistance, and poor stability. After a long time of painting, they are easy to crack and fall off. It is generally not high. When it is polluted, if it is not cleaned in time, it will be difficult to clean it. If it is repeatedly wiped, dark marks will appear on the wall; the composition contains formaldehyde, which not only pollutes the environment, but also causes harm to human health.

Abstract

The invention relates to the field of chemical paints, particularly an antifouling acrylic latex paint. The latex paint comprises 55-75 parts of acrylic emulsion, 15-25 parts of film-forming assistant, 1.5-2.5 parts of sodium hydroxide, 20-45 parts of titanium white, 10-35 parts of ethylene glycol, 3-6 parts of methane-siliconic acid, 100-200 parts of wetting and dispersing agent, 6-10 parts of ground calcium carbonate, 15-35 parts of defoaming agent, 6-9 parts of sodium polyphosphate dispersing agent, 3-4 parts of nano silicon dioxide, 25-45 parts of preservative and 10-30 parts of deionized water. The antifouling acrylic latex paint can be coated on the external wall by scratch coating, spray coating or the like, and the drying time is short. The latex paint has the advantages of favorable water resistance, favorable fouling resistance, favorable mold and bacterium resistance, favorable rubbing resistance, favorable weather resistance, favorable ultraviolet resistance and excellent stain resistance, and can be widely used in offices, classrooms and families. The paint is simple in manufacturing process and convenient to operate, and has long service life.

Description

Technical field [0001] The invention relates to a latex paint, in particular to an antifouling acrylic latex paint, which belongs to the technical field of chemical coatings. Background technique [0002] There are many types of traditional latex paints on the market. Traditional latex paints have poor antifouling effect, poor resistance to rubbing, poor aging resistance, and poor stability. After a long time of painting, they are easy to crack, fall off, and have anti-fouling ability. It is generally not high. When it is polluted, it is difficult to clean again if it is not cleaned in time. If it is repeatedly wiped, dark marks will appear on the wall; the composition contains formaldehyde, which not only pollutes the environment, but also causes harm to human health . Therefore, it has become a market need to provide an anti-fouling emulsion paint that is harmless to the human body and the environment and is relatively inexpensive. Summary of the invention [0003] In view of ...
