Wear-resistant anti-aging exterior wall coating forming method

Abstract

The invention discloses a wear-resistant anti-aging exterior wall coating forming method which comprises the following steps: sequentially brushing a wall surface and a wainscot by taking the outer side of the wall surface of an exterior wall body as a brushing surface, and before brushing, preparing a wall surface base coating by utilizing styrene-acrylate emulsion, reinforced fibers, quartz sand, bentonite, carboxymethyl cellulose and water; and firstly, thickly coating a wall surface base by utilizing the wall surface base coating, then brushing cement mortar with array holes at the position of a wainscot corresponding to the wall surface, then carrying out roller coating on the surface of the cement mortar by utilizing a gum coating prepared from acrylate emulsion, ethylene glycol butyl ether, high-alumina cement, bentonite, heavy calcium carbonate and water, and forming a facing layer after roller coating, so as to obtain a formed outer wall coating. The whole outer wall surface can be treated, and the treated outer wall surface is good in integrity and has better wear-resisting, heat-preserving, damp-proof and anti-aging effects.

Description

technical field [0001] The invention relates to the technical field of coatings for exterior walls of buildings, in particular to a method for forming a wear-resistant and anti-aging exterior wall covering. Background technique [0002] Architectural coatings are indispensable decorative and protective functional materials in the construction industry, while exterior wall coatings are used for decorative painting of exterior walls, and also have functional effects such as heat preservation, heat insulation, waterproof, and crack prevention. Compared with traditional ceramic tiles and wall decorative stones, the exterior wall coating has good adhesion performance, less burden on the wall, good integrity, good decoration and good surface finish after painting and molding, and has better weather resistance during use , It is not easy to fall off or peel off, and even if it peels off under special circumstances, it will not cause great harm.

Problems solved by technology

[0003] With the improvement of people's living standards, more and more rural self-built houses have begun to use exterior wall coatings on the exterior walls, but the coating method is relatively simple, and single-material wall coatings are mostly used as raw materials. brush to paint the entire surface, most of the exterior wall paints used are water-emulsified exterior wall paints, and most of them are modified with aliphatic vinylamines, emulsifying aids, and co-solvents, and emulsification is required during the modification process Thinners or alcohol ether diluents, these substances have a certain smell, and do not participate in the curing reaction, and will release certain toxicity

[0004] In addition, since most of the self-built houses in rural areas are low-rise bungalows, the root of the wall is relatively humid, and it is easy to have different degrees of floating oil or oil slicks when painting the entire wall, resulting in a decline in the quality of wall painting. , in rural self-built houses, the walls are usually not smoothed after the concrete is formed, so the exterior wall paint that is directly painted is not well bonded to the concrete as a whole, and there are problems such as low forming strength. Oil delamination occurs with increasing time, risk of warping

Moreover, the use environment of self-built houses in rural areas is usually not good, and the overall anti-wear and scratch resistance of the wall surface after the water-emulsified exterior wall paint is poor, and the traces are obvious after bumping, which affects the appearance, and the formed paint film There will be a certain internal stress in the layer, which will cause the wall coating to crack easily when it receives an external force, which will affect the functional use and overall aesthetics of the wall coating
