Composite decorative material with flexibility and production process thereof

Abstract

The invention discloses a composite decorative material with flexibility and a production process thereof. The composite decorative material with flexibility comprises a flexible base layer, a flexible sand textured coating layer and a stain-resistant protective finish layer. The flexible sand textured coating layer and the stain-resistant protective finish layer are arranged on the flexible base layer in sequence; the flexible sand textured coating layer comprises water, cellulose ether, a film forming additive, an antifreeze, a flexible latex, natural color sand, composite rock slices, a pH adjustment agent and a defoamer. Due to the adoption of the mode, the multifunctional decorative material which is developed according to the building and the decoration surface is convenient to construct, has good weather resistance, can be designed, cut and spliced randomly and can be adhered by special adhesive to achieve various simulate stone and brick effects. Due to the adoption of the composite decorative material with flexibility, the load of the wall can be greatly reduced, the wall of each square meter is about 1 / 3 the weight of the wall bricks, and the problems of high-altitude construction difficulty and safety can be solved.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a flexible composite decorative material and a production process thereof. Background technique [0002] Stone and ceramic tiles traditionally used for decoration are heavy, hard, fragile, and high in energy consumption. When applied to walls, they often fall off due to poor adhesion, radioactive pollution, public hazards, and injuries. At the same time, the production of tiles The energy waste and greenhouse gas emissions caused by high-temperature sintering are contrary to the current environmental protection requirements in the world. Policies and regulations prohibiting the use of stone materials in high-rise buildings have been continuously issued. Therefore, the development of new stone-like materials with low energy consumption, light weight, weather resistance, pollution-free and non-radioactive has become an inevitable trend. [0003] At present, the texture coatin...

AI Technical Summary

Problems solved by technology

Since the above-mentioned imitation stone coatings all use emulsion with a high Tg value as the polymeric bonding base material, which is not very flexible, it cannot be well covered when the wall is cracked due to thermal expansion and contraction. As a result, the coating cracks and cannot have a good protective and decorative effect on the wall. Air and moisture will penetrate into the wall from the cracks, causing the base layer to pulverize and the surface coating to peel off, and because the texture paint is generally thick paste Therefore, during the construction process, due to the uneven thickness of the coating during spraying or batch scraping, serious color difference will occur. After construction, tearing the masking paper will produce burrs, which greatly affects the aesthetic effect of the coating.
