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 decoration coating painted ceramic stone and a production technology thereof. The coating painted ceramic stone adopts 40-80 mesh ceramic sands, the thickness of the coating layer of the above product is 2mm, and the disadvantages of single color, easy efflorescence, insufficient thickness and no crack resistance function of traditional emulsion paints are overcome; the color of the ceramic sands can be sintered arbitrarily, and is stable, so the painted ceramic stone has the advantages of grittiness of texture coatings, no need of any color paste, no color fading risk, uniform particle size, and great reduction of the lapping defect generation; and silica sol is introduced in the formula of the painted ceramic stone, a film composite base material is arrayed in a spherical or subglobular manner, and the surface is flat and compact and has few apertures, so fine dust particles cannot intrude the apertures, and cannot adhere, thereby the coating layer has good contamination 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...
