Abstract

The invention provides a multifunctional coalescing agent and a preparation method thereof and further provides a self-made thickening agent, a base material and an exterior wall coating or tile coating prepared with the multifunctional coalescing agent. The multifunctional coalescing agent comprises a coalescing agent A, a coalescing agent B, a coalescing agent C, cellulose, an antifoaming agent, a self-made dispersing agent, an OP-series emulsifier, a 30-wt% inorganic nano-silicon aqueous solution and styrene-acrylic emulsion, wherein the self-made dispersing agent comprises an acrylic dispersing agent, a coupling agent TC-2, a dispersing agent 5040 and water. Besides, the exterior wall coating or tile coating has super color retention, super ageing resistance, super water repellency and low VOC content, and production cost is quite low. Therefore, the multifunctional coalescing agent, the self-made thickening agent, the base material and the exterior wall coating or tile coating have excellent market prospects.

Description

technical field [0001] The invention belongs to the field of chemical building materials, and in particular relates to a multifunctional film-forming auxiliary agent and a preparation method thereof, and also relates to a self-made thickener, a base material and an external preparation prepared by using the multifunctional film-forming auxiliary agent. Wall paint or tile paint. Background technique [0002] Exterior wall paint is a paint used to paint the exterior wall of a building. The properties usually required include: 1. Good decoration: the exterior wall paint is required to have rich colors and excellent color retention, and can maintain the original color for a long time. 2. Good weather resistance: Exterior wall coatings, because the coating is exposed to the atmosphere, have to withstand the effects of wind, sun, salt spray corrosion, rain, cold and heat changes, etc., in these external natural environments Under long-term repeated action, the coating is prone to...
