Ultra-weather resistant building outer wall paint film wall cloth and manufacturing process thereof

Abstract

The invention relates to an ultra-weather resistant building outer wall paint film wall cloth and a manufacturing process thereof. The paint film wall cloth provided by the invention comprises a paint film colored sheet layer and a base material layer which are integrally formed, wherein the paint film colored sheet layer is formed by coating the two surfaces of a glass fiber cloth with color paste, drying the glass fiber cloth, and grinding the glass fiber cloth; the color paste is prepared by mixing a natural mineral pigment, and an elastic emulsion type glue solution or fluorocarbon coating according to certain parts by weight; the base material layer is formed by coating the two surfaces of a fiberglass-polyester mixed surface felt with thick plasma type emulsion, and drying the fiberglass-polyester mixed surface felt. According to the ultra-weather resistant building outer wall paint film wall cloth provided by the invention, the defects that difficulty in paint coating, uneven thickness after coating, easiness in loosening, sand falling and the like of the traditional granite paint are overcome; a paint film colored sheet and a base material are integrally formed through hot pressing, the thickness of the paint film colored sheet layer on the base material layer is strictly controlled in a manufacturing process, a vacuum step is strictly controlled, and an UV (ultraviolet) machine is used for glazing to seal and cure, so that the decorating wall cloth provided by the invention is high in uniformity, flatness, anti-water ability, antioxidant ability and ultraviolet resistance. The blank of outer wall decorating wall cloth in the market is filled.

Description

technical field [0001] The invention belongs to the field of decorative materials, and in particular relates to a super-weather-resistant building exterior wall paint film wall covering and a manufacturing process thereof. Background technique [0002] Over the years, the building exterior wall decoration industry has developed rapidly, with a wide variety of products ranging from natural stone, ceramics, synthetic panels, and coatings. Coatings occupy a considerable share in building exterior wall decoration materials. Coatings have the advantages of cheap price, easy construction, and short construction period; at the same time, coatings in building exterior wall decoration materials have gradually shown poor weather resistance and poor decorative effects. Good and other obvious defects. In order to overcome this defect, a new generation of products represented by real stone paint has emerged in recent years. Rock flake paint (also known as imitation granite paint) is a ...

AI Technical Summary

Problems solved by technology

Rock flake paint (also known as imitation granite paint) is a pure water-based sand wall-like architectural coating. The effect of spraying is full of granite style. Excellent product, but there are still many defects in the process of use, and it cannot fully meet the high quality requirements of consumers

[0003] First of all, whether it is real stone paint or rock flake paint, a large number of tiny air bubbles are produced in the paint film during spraying. After drying, the paint film is loose and not dense enough. The water absorption rate of the paint film is relatively high, and the bonding strength is correspondingly reduced. , rainwater will penetrate into the paint film, causing the paint film to turn white when it meets water and have poor water resistance; moreover, the paint film with weak compactness and loose appearance is prone to decompose and decompose colored substances when it is irradiated by ultraviolet rays from the sun, eventually causing yellowing Discoloration etc.

In order to achieve a realistic effect comparable to natural granite, rock flake paint is sprayed with PVC color flakes. PVC color flakes are easy to fade, oxidize, and have poor weather resistance. When spraying, sand will fall off and splash around, polluting the environment. In severe cases, it can waste three If the thickness is uneven during the construction process, or the paint film is too thin, it will cause blooming phenomenon, which will bring difficulty to the construction and greatly reduce the life of the paint film.

Moreover, with artificial spraying, due to the difference in the technical level of the spraying construction personnel, the spraying effect is inconsistent, there are color differences, poor texture, inconsistent flatness, and inconsistent thickness, which greatly reduces the decorative effect.
