Problems solved by technology

[0004] Finishing mortar is an inorganic material, which has the problem of high water absorption. Water absorption of the coating will bring pollution sources into the coating, resulting in coating pollution. In addition, free alkali metal ions in the coating will migrate to the surface of the coating with water. , causing pan-alkaline phenomenon, which affects the decorative effect of the facing mortar, and the long-term migration of moisture will affect the structure of the coating and affect the durability of the coating.
[0005] In order to solve the above problems, there are currently some finishing paint applications on the market, but the weather resistance and stain resistance of these finishing paints cannot be optimized at the same time, so they cannot provide long-term and durable protection for the finishing mortar coating

Abstract

The present invention discloses a finish coat paint for facing mortar. The finish coat paint comprises the following components, by weight, 15-25% of an antifouling polymer, 10-20% of an emulsion, 5-10% of an additive, and 40-60% of water. With the technical scheme of the present invention, the antifouling polymer is adopted as the main component by the finish coat paint of the present invention, wherein the main component of the antifouling polymer is an organic fluorine resin, and the antifouling polymer has special surface performances of stain resistance, water repellency, oil repellency, and the like so as to provide a good antifouling effect; with additions of the emulsion, the additive and the like, the disadvantages of the antifouling polymer are improved so as to achieve high quality complementation and completely provide respective effects.

Description

technical field [0001] The invention relates to the field of finish paint, in particular to a finish paint which provides long-term protection for the finishing mortar coating. Background technique [0002] Finishing mortar is a new type of inorganic powdery decorative material, which is usually made of cement as the cementitious material, combined with high-quality mineral aggregates, polymers, fillers and natural mineral pigments. Through the selection of aggregates with different particle sizes, as well as the use of different construction molds and construction methods during the construction process, different methods such as dragging, rolling, scraping, twisting, pressing, and kneading are used to make the wall surface change into embossing, corrugation, Various patterns such as wood grain form a variety of textures, colors and textures, and are highly decorative. [0003] The facing mortar has good air permeability, good impact resistance, excellent cohesiveness, lig...
