Abstract

The invention discloses a preparation method of an alkali-resistant water-based metal exterior wall coating, which comprises the following steps: (1) adding cerium chloride and yttrium chloride into water, mixing and stirring evenly, and heating it to 75-85°C Afterwards, continue to add sodium erucate to it, mix and stir evenly, and heat preservation treatment to obtain an alkali-resistant additive; (2) Pure acrylic emulsion, water, polyglycerol monostearate, tripotassium citrate, cyclohexyl Calcium sulfamate, alkali-resistant additives, metallic pigments, wetting and dispersing agents, and defoamers are uniformly mixed, and then stirred continuously to obtain finished products. The preparation method of an alkali-resistant water-based metal exterior wall paint provided by the present invention has wide sources of raw materials and low cost, and the prepared water-based metal exterior wall paint has good construction performance, no obstacles for two coats, water resistance, and scrubbing resistance Excellent performance, especially excellent alkali resistance and long service life.

Description

technical field [0001] The invention belongs to the technical field of exterior wall coatings, and in particular relates to a preparation method of an alkali-resistant water-based metal exterior wall coating. Background technique [0002] Exterior wall paint is used to paint the exterior walls of buildings, so the most important indicator is anti-ultraviolet radiation, which requires long-term exposure without discoloration. Some exterior wall coatings also require water resistance and self-cleaning properties. The paint film should be hard and smooth, and the dirt will fall off as soon as it is washed. Although the exterior wall coatings prepared in the prior art can meet the above requirements, they have poor alkali resistance, resulting in a short service life. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a preparation method of an alkali-resistant water-based metal exterior wall paint. ...
