The existing environmental protection wall coatings are divided into water-based latex coatings and oil-based environmental protection wall coatings. The construction of water-based latex paint is greatly affected by temperature, so it cannot be applied in colder areas, and it also has requirements on humidity. When the humidity is high, the drying period is too long. In addition, the existing water-based latex coatings have poor anti-fouling performance, do not have good water resistance and wear resistance, are easy to chalk, fade, have poor anti-aging properties, and have problems such as low gloss of the coating film. CN201511015561.X provides a durable new latex paint and a preparation method thereof, which have the advantages of less volatile organic compound content, less environmental pollution, energy saving, emission reduction, low carbon and environmental protection.
In order to solve the above-mentioned technical problems, the technical scheme adopted in the present invention is that a durable new latex paint is made from the following raw materials in parts by weight: 15-22 parts of white latex, 3- 7 parts, 2.5-6.8 parts of light calcium carbonate, 10-30 parts of deionized water, 2.5-3.7 parts of oxalic acid, 2.5-6.8 parts of Undecanal and 3.8-9.5 parts of ethyl 2-chloro-3-oxobutyrate. Optimized, the above-mentioned durable new latex paint is made from the following raw materials in parts by weight: 19 parts of white latex, 5 parts of 5-methyl-1-hexanol, 4.2 parts of light calcium carbonate, 18 parts of deionized water, 3.1 parts of oxalic acid, 4.2 parts of Undecanal and 6.9 parts of ethyl 2-chloro-3-oxobutyrate.
Compared with the existing product, the present invention improves the mildew resistance and scrub resistance of the latex paint after mixing oxalic acid, Undecanal and ethyl 2-chloro-3-oxobutyrate, improves the life of the finished latex paint, and can Widely used for wall painting.
