Problems solved by technology

[0003] However, among the existing paints, latex paints and textured paints use color paste to adjust the color, the color is single, and they are easy to fade after being exposed to the sun and rain, and the durability is insufficient. At the same time, the coating of real stone paint is thick and takes a long time to dry. If it rains within 2 hours after construction, it is easy to be washed off.

Embodiment 1

[0027] This embodiment mainly selects the cleaning aids in the pottery color stone formula.

[0028] At present, the self-cleaning additives used in architectural coatings on the market mainly include: (1) Hydrophobic self-cleaning theory, people develop coating surfaces with low surface energy, simulating the surface of lotus leaves, in order to achieve the purpose of self-cleaning, the representative product is LC- 808 lotus leaf additive; (2) silica sol; (3) hydrophilic and stain-resistant theory, hydrophilic makes the surface of the coating easy to be wetted by water, and the stains adhering to the surface are easily washed away. The representative product is X -405 wetting agent; (4) Micronized coating film, adding easily pulverized pigments to the coating, and the pulverized pigments and contaminants will be taken away together when the rain washes away. The representative product is 1250 mesh talcum powder.

[0029] According to the performance detection method in the i...

Embodiment 2

[0039]The present embodiment mainly selects the cellulose in the pottery colored stone formula. The workability of ceramic colored stone is mainly affected by the thickening system and solvent. We need to adjust the workability of the coating by selecting the added cellulose. According to the performance test in the industry standard JG / T24-2000 "Synthetic Resin Emulsion Sand Wall Architectural Coatings" Method, the present embodiment selects several commonly used celluloses in the market and adds them to the emulsion for comparative testing. The results are shown in Table 3:

Embodiment 3

[0053] Preferably, in the pottery colored stone formula, wherein bactericide and antimold agent all adopt the bactericide LEX and antimold agent 363 that American Rohm and Haas Company produces, and the cellulose that selects the model that Klein Chemical Co., Ltd. produces is the cellulose of 100000YP2, In the selection of film-forming aids, in this example, the alcohol ester TEXANOL produced by Eastman Company was selected as the film-forming aid, the defoamer was selected from A-203, and the adhesive was selected from Changshu Badefu Technology Co., Ltd. The type is RS706T, and the thickener is TT615 produced by Rohm and Haas Company of the United States.

[0054] Prepare pottery colored stone finished products according to the formula in Table 6.

Abstract

The invention provides a building decorative paint pottery color stone and its production process. The paint pottery color stone adopts 40-80 mesh ceramic sand, and the coating thickness of the product is 2mm, which solves the problems of single color, easy pulverization, and insufficient thickness and no crack resistance of traditional latex paint Functional disadvantages; at the same time, the color of ceramic sand can be fired at will, and the color is stable. While having the sandy feeling of textured paint, there is no need to add any color paste, no risk of fading, and the particle size is uniform. During the construction process , greatly reducing the occurrence of joint marks; by introducing silica sol into the ceramic color stone formula, the composite base material of the coating film is arranged in a spherical or close to spherical shape, the surface is flat and compact, and the pores are less, making it difficult for fine dust particles to invade its pores, and the dust is difficult to stick Attached, the coating itself has good stain resistance.

Description

technical field [0001] The invention belongs to the technical field of building decoration coatings, and in particular relates to a pottery colored stone formula and a production process thereof. Background technique [0002] At present, the mainstream exterior wall paints in China are mainly three types: latex paint, real stone paint, and texture paint. Latex paint is a water-dispersible paint. It is made of synthetic resin emulsion as the base material. After the filler is ground and dispersed, it is refined by adding various additives. Latex paint has many advantages different from traditional wall paint. Brushing, fast drying, water-resistant paint film, good stain resistance, etc. Real stone paint is a kind of thick paste paint with decorative effect similar to marble and granite. It is mainly formulated with natural stone powder and acrylic polymer emulsion of various colors. The buildings decorated with real stone paint have natural and real natural color. It is a r...
