Problems solved by technology

[0004] In the past, the inorganic dry powder texture paint on the market could not control the stability of the color because it was easy to return to alkali, so it could only be used as a texture layer, and then painted with latex paint on the surface, so that the durability of the inorganic material was not fully utilized, so With the development of the national economy, the market has more and more demands for various paint shapes, and the durability of the paint is also higher and higher. It is necessary to develop a new inorganic dry powder texture paint that can be used in color, with texture and color, to make it Give full play to the performance of inorganic dry powder texture coating

Embodiment 1

[0040] The component and content of the inorganic dry powder coating of the present embodiment are: inorganic binding powder bentonite 10%, mineral sand 55.7%, heavy calcium powder 30%, organic binding rubber powder (FX2350) 4%, methyl cellulose 0.2%, Polypropylene fiber 0.1%.

[0041] Its preparation process is as follows:

[0042] The inorganic dry powder coating is produced by a dry powder mixer, and the powder is produced by a fully automatic electronic control feeding device to ensure the accuracy of feeding.

[0043] Feeding sequence: first put in ore sand and heavy calcium, and then put in inorganic bonding powder, organic rubber powder, cellulose, and polypropylene fiber in sequence.

[0044] The powder is mixed in the mixer for 800-1000 seconds to make the powder evenly mixed, and each batch is sampled to check the uniformity of the powder.

[0045] After inspection, the performance of the inorganic dry powder coating of the present embodiment is as follows:

Abstract

The invention provides an inorganic dry powder painting mainly comprising inorganic bonding power, organic bonding gelatine powder, ore sand, triple superphosphate powder, cellulose and polypropylene fiber. In the inorganic dry powder painting, a film is formed by compounding organic and inorganic film materials, so that the inorganic dry powder painting can have the endurance quality of an inorganic painting and the anti-cracking quality and easy construction operation quality of an organic painting. A coating made by using the inorganic dry powder texture painting has diversified shapes and attractive and natural texture, and a plurality of shapes of the coating cannot be realized by organic materials at all.

Description

technical field [0001] The invention relates to a coating for building, in particular to a decorative coating for interior and exterior walls. Background technique [0002] At present, the water-based decorative coatings used on building walls mainly include: latex paint, real stone paint, artistic texture paint, inorganic dry powder paint, etc. As a flat paint, latex paint has no texture effect and no three-dimensional texture. Real stone paint is made of natural colored sand mixed emulsion, which has texture and three-dimensional effect, but the color of natural colored sand is unstable, and the color of paint is difficult to control. In recent years, the country has greatly improved the environmental protection standards. Sand supplies are limited. [0003] There are generally three methods of texture paint: ①Emulsion type texture paint as the texture layer, and the surface layer is painted with latex paint for coloring; ②Emulsion type adjustable texture paint; ③Inorgan...
