Abstract

The invention discloses an improved external wall paint which is prepared from the following raw materials in parts by weight: 5-10 parts of attapulgite powder, 22-28 parts of white latex, 5-10 parts of titanium white, 7.5-8.5 parts of deionized water, 6-12 parts of hydroxyethyl cellulose, 3.5-7.2 parts of trans-2-hexenal, 4.5-8.5 parts of phenethyl phenol polyethenoxy ether, 1.2-3.5 parts of polyurethane modified nitrocellulose film former and 2.5-3.7 parts of dispersing agent. Compared with the existing latex paint, the external wall paint has the advantages of has the advantages of favorable weather resistance, favorable ultraviolet resistance and short drying time. After the hydroxyethyl cellulose and trans-2-hexenal are added, the coated film is flat and smooth, and has delicate tactile sensation. After the polyurethane modified nitrocellulose film former is added, the finished product has high fouling resistance and excellent adhesive force, can effectively prevent mildew and algae, has favorable leveling property, is safe and convenient for construction, and is an ideal external wall decorating material.

Description

Technical field [0001] The invention involves an improved exterior wall coatings and its preparation methods, which belongs to the field of architectural coatings. Background technique [0002] At present, there are many types of coatings used in exterior walls. Latex paint is one of the most widely used wall decorative materials, and latex paint is the most secure material among many coatings.The exterior wall latex paint not only requires good weather resistance, ultraviolet resistance, and the coating film should also be smooth and smooth, and the texture is delicate, while the existing existing lateral wall latex paint is difficult to meet the required requirements at the same time. Invention content [0003] In response to the lack of existing technology, the technical problem to be solved by the present invention is to provide an improved exterior wall coatings and their preparation methods, comprehensive performance, high weather resistance and ultraviolet resistance, and...
