Embodiment Construction

[0013] The following is an embodiment of the present invention.

[0014] The composition (percentage by weight) and production process of the elastic coating of the present invention are as follows: in the low-speed stirring stage, 11 parts of deionized water, 0.15 parts of multifunctional additive AMP-95, 0.1 part of wetting agent X405, 0.55 parts Polyacrylic acid amine salt dispersant PR03, 0.15 parts of defoamer NXZ, 2.5 parts of propylene glycol, 18 parts of titanium dioxide 595, 7 parts of precipitated barium sulfate with a fineness of 800 mesh, 8 parts of ground calcium carbonate with a fineness of 1250 mesh, etc. After adding, enter the high-speed stirring stage. After stirring evenly, grind at high speed until the fineness is ≤50um, and then add 42 parts of soap-free emulsion AP5085, 4 parts of opaque polymer Youchuang, 0.8 parts of Texanol, 0.8 parts of Anti-stain additive NM-1, 0.15 parts of defoamer NXZ, 0.15 parts of preservative MV, 0.4 parts of Newtonian nonionic...

Abstract

The invention relates to single layer fouling resistant water proof elastic coating, which comprises components with the weight proportion being as follows: 10-20 percent of water, 0.1-0.2 percent of multi-purpose accessory ingredient, 0.1-0.2 percent of wetting agent, 0.4-0.8 percent of dispersant, 0.3-0.8 percent of antibubbling agent, 1.5-3.0 percent of propylene glycol, 16-20 percent of rutile type titanium white powder, 6-8 percent of precipitated barium sulfate, 5-8 percent of large calcium carbonate, 3-5 percent of nontransparent polymer, 38-45 percent of latex, 0.8-1.5 percent of Texanol, 0.5-1 percent of fouling resistant accessory ingredient, 0.1-0.2 percent of anticorrosion agent, and 0.6-0.9 percent of thickening agent. The product overcomes the deficiencies of poor water tolerance, poor water resistance, poor fouling resistance, etc. of the traditional elastic coating, and has the outstanding waterproof performance, fouling resistant performance and good breaking strength, and can obviously improve the performances of waterproofing, fouling resistant and crack resistant. The invention can prevent and cover the crackles on the building and can ensure that the outer wall surface of the building can keep clean and magnificent for a long time.

Description

technical field [0001] The invention relates to a coating, in particular to an elastic coating which is used for protection and decoration of the exterior wall of buildings and has high stain resistance and crack-covering ability, and belongs to the technical field of chemical coatings. Background technique [0002] Looking at the entire domestic elastic coating market at present, most of the products are only limited to the characteristics of high elasticity, their water resistance and water resistance are poor, their tensile strength is low, and their adhesion is average. Because it is not water-resistant or waterproof, its paint film will peel off as a whole after being washed by rain, or crack or peel off due to the difference in moisture content, and rainwater will seep into the wall and corrode the wall. At the same time, due to the poor stain resistance of the elastic coating, it is easy to be polluted by dust and oily substances suspended in the atmosphere after cons...
