Natural stony exterior wall thermal insulation plate finishing paint having levelling property and preparation method of finishing paint

Abstract

The invention relates to a natural stony exterior wall thermal insulation plate finishing paint having levelling property. The natural stony exterior wall thermal insulation plate finishing paint is prepared by compounding stone chip powder, silicone acrylic emulsion, a thickening agent, a levelling agent, a dustproof agent, an anti-ultraviolet agent, a pH value adjustor with deionized water; the natural stony exterior wall thermal insulation plate finishing paint is compact in paint film, strong in adhesive ability, high in weather fastness and water resistance, green, environmentally friendly and ageing-resistant; furthermore, the natural stony exterior wall thermal insulation plate finishing paint has excellent levelling property; particularly, the levelling property is better in a vibration state; a paint surface of a thermal insulation ornamental plate is uniform, flat and, smooth, enough in lustre, natural in colour and authentic in texture; the true stone simulation effect of the finishing paint is up to 97-100%; the natural stony exterior wall thermal insulation plate finishing paint has good decorative property and strong in self-cleaning ability; after being washed by rainwater, the natural stony exterior wall thermal insulation plate finishing paint is bright as new, green and environmentally friendly; the main raw material, namely the stone chip powder, is waste stone chips; wastes are turned into wealth; the natural stony exterior wall thermal insulation plate finishing paint is low in cost, natural in color and authentic in texture; simultaneously, the invention provides a preparation method of the natural stony exterior wall thermal insulation plate finishing paint; and the preparation method is simple, convenient, easy to operate and strong in generalizability.

Description

technical field [0001] The invention belongs to the technical field of building wall decoration materials, and in particular relates to a leveling natural stone exterior wall insulation board finish paint suitable for exterior wall decoration and a preparation method thereof. Background technique [0002] At present, with the rapid development of construction and exterior wall decoration in our country, building thermal insulation and energy saving are becoming popular, and external thermal insulation panels have become the leading products for building energy conservation. With the improvement of people's requirements for beautifying buildings and the increasing awareness of energy conservation and environmental protection, higher and higher requirements are put forward for new building wall decoration materials, which require both light weight and thin layers, durability, and stain resistance. It also has strong anti-cracking and anti-aging properties, and it must also dec...

Problems solved by technology

However, the current real stone paint has the following defects in wall decoration: 1) Poor leveling, the surface of the paint film is relatively rough, even through vibration leveling, it is difficult to achieve a flat finish on the paint surface, and the paint film has an uneven feel after drying , leading to easy dust accumulation, dust suction and other pollution, it is difficult to clean, especially for high-rise buildings, it is very difficult to clean and maintain, and the operation is extremely unsafe; 2) It is easy to crack and peel, and the film thickness is much thicker than that of ordinary latex paint. The paint film is not firmly adhered to the wall surface and there are local cracks and peeling phenomena; 3) Fading, after the traditional real stone paint is soaked in rain, it is easy to turn white, and it will turn yellow after exposure to the sun, which seriously affects the decorative effect
