Description
Technical Field
The invention relates to a water-based crack art coating and a preparation method thereof, which are applied to the field of art coatings.
Background
The crackle coating is an art coating with special decoration function, is commonly used for artware, building decoration and home decoration, and can achieve the decoration effects of archaizing and the like by matching with special colors. In the application of building interior walls, the crackle coating can form natural crackle patterns after construction, and the crackle effect patterns are various according to the difference of construction process, construction environment conditions and formula color matching, so that the crackle coating has unique visual effect as an artistic coating. In recent years, with the personalized pursuit of products and home decoration by consumers of art coatings, the water-based crack coating is gradually developed and applied.
The traditional crack coating in the current market mainly takes a solvent type as a main component, belongs to nitro crack coating, and adopts the principle that an organic solvent in the crack coating is utilized to dissolve a nitro primer, and the shrinkage degree of the nitro primer in the drying process is greater than that of the finish coating, so that the finish coating is pulled and torn in the drying process, and then the primer is penetrated to form cracks. However, with the development of the times, the environmental protection requirement of the interior decoration paint is higher and higher while consumers continuously pursue the artistic effect of the crack paint. The solvent-based coating uses a large amount of organic solvent in the production process, so the coating has higher VOC content and obviously does not meet the requirement of building interior wall application. The organic solvent in the formula can release a large amount of VOC, and the VOC can cause serious harm to the health of constructors and consumers. Meanwhile, the use of organic solvent can generate larger smell, tools for construction are difficult to clean, the development of the construction process is not facilitated, meanwhile, the construction method can cause great harm to the physical health of constructors and consumers, and the construction method is extremely unsuitable for high-end home decoration scenes such as building interior wall decoration, especially artistic paint and the like. In combination with the hazards and disadvantages of the solvent type crack coating, the corresponding water-based crack coating is developed and popularized. Secondly, from the consideration of the construction process and the product, after the solvent-based crack coating finish paint is dried, the film forming substance is brittle, the adhesive force needs to be improved, a layer of cover is generally required to be sprayed on the surface to protect the crack effect, and the construction difficulty and the construction cost are increased. In the selection of the building interior wall decorative coating, consumers generally use environmental protection and health as the primary principle, and then the beauty and the weather resistance of the product are achieved, and the traditional solvent-based crack coating cannot meet the technical index requirements of the building interior wall decorative coating in many aspects, so that the application market of the coating is limited to a great extent.
Namely, the existing crack coating on the market has the following defects:
1. the coating is mainly solvent-based, is not environment-friendly and is not suitable for being used in building interior wall decoration;
2. the existing water-based crack coating for the inner wall on the market has higher construction difficulty, and the process has larger influence on the product effect and is not beneficial to large-area construction.
In addition, the existing crack coating has the problems of poor water resistance, poor chemical stability, short service life and the like in an aqueous system.
Therefore, it is a great need to provide a water-based crack art paint with environmental protection, easy construction, good water resistance and chemical stability, and long service life, and a preparation method thereof.
Disclosure of Invention
In order to overcome the defects that the existing solvent type crack coating is not environment-friendly, has higher construction difficulty, has larger influence on the product effect by the process, is not beneficial to large-area construction and the like, the invention provides the water-based crack art coating and the preparation method thereof.
The technical scheme of the invention is as follows:
the water-based crack artistic coating comprises a crack primer and a crack finish, wherein the crack primer is prepared from the following components in parts by weight:
6-18 parts of water
0.5 to 1.0 portion of aqueous dispersant
0.5 to 1.0 portion of water-based wetting agent
0.5 to 1.0 portion of water-based defoaming agent
1-5 parts of white carbon black
2-3 parts of talcum powder
1-5 parts of mica powder
1-2 parts of silane coupling agent
50-70 parts of polyacrylic emulsion
2-5 parts of antifreeze
1-5 parts of film-forming assistant
1-2 parts of preservative
2-7 parts of water-based color paste
2-5 parts of an aqueous thickening agent;
the crack finish paint is mainly prepared from the following components in parts by weight:
8-19 parts of water
0.2 to 0.5 portion of pH regulator
0.3 to 1.0 portion of aqueous dispersant
0.5 to 1.0 portion of water-based wetting agent
0.5 to 1.0 portion of water-based defoaming agent
1-2 parts of wollastonite
1-4 parts of barium sulfate
1-5 parts of hollow covering polymer microspheres
55-70 parts of pure acrylic emulsion
1-5 parts of antifreeze
1-3 parts of film-forming assistant
1-2 parts of preservative
2-5 parts of water-based color paste
2-5 parts of an aqueous thickening agent.
Most of the existing solvent-based crack coatings are nitro-crack finish paints, are matched with common nitro-primer for use, and are pulled and torn by utilizing the difference of the shrinkage degrees of the primer and the finish paint to form a crack effect. Similarly, the artistic effect of the water-based crack coating also utilizes the difference of shrinkage degrees between the primer and the finish paint in the drying stage, so that a larger acting force is generated on the finish paint, the paint film is finally difficult to bear and is broken, and the broken paint is shrunk continuously along with drying to form a crack effect with random sizes. However, the water-based crack coating is more in line with the principles of environmental protection and health due to the adoption of a water-based system, and has better application prospect. The water-based crack artistic coating selects polyacrylic emulsion and pure acrylic emulsion respectively, combines wollastonite, white carbon black, hollow covering polymer microspheres, barium sulfate and other pigments and fillers, is applied to a water-based coating system through dispersion system optimization, prepares crack primer and crack finish coat, can realize various crack sizes and texture effects after being matched and used, has the advantages of low VOC, environmental protection and the like, and has natural and unique artistic effects, and is easy to construct, good in water resistance and chemical stability and long in service life, and suitable for decoration and application of building interior walls. The acrylic emulsion has the advantages of good film forming property, water-based environmental protection, good adhesion to various base materials and various paint surfaces and the like, and the acrylic emulsion has the advantages of high hardness, quick drying, anti-sticking, good crack effect and the like, is respectively selected as a crack primer and a crack finish, and has the advantages of low VOC and odor purification. Meanwhile, the low VOC auxiliary agent in the system is combined, so that the crack effect and stability are fully guaranteed, the environmental protection performance of the product is improved, the product is more suitable for the construction environment of the building inner wall, and the health and application requirements of constructors and consumers are met. The addition of white carbon black, mica powder and other pigments and fillers can effectively improve the hardness of a paint film of the paint, reduce the internal shrinkage stress of a primer coating and prevent the coating from curing and cracking. Barium sulfate and hollow covering polymer microspheres can effectively improve the scratch resistance and stain resistance of the finish paint, provide covering and color mixing effects, and provide artistic decoration effect by matching with water-based color paste. After the pigments and fillers are compounded in proper proportion, various performances can be balanced. And the addition of various functional additives also provides certain corrosion resistance and freezing resistance for the coating. The water-based crack art paint successfully fills the blank of interior wall decorative water-based crack paint products in the market; the crack coating overcomes the pain problems of poor water resistance, poor chemical stability, short service life and the like of the existing crack coating in a water-based system, and is expected to realize large-scale popularization in the field of decorative interior wall coatings.
