Description
Technical Field
The application relates to the technical field of coatings, in particular to a colorful spar coating and a preparation method thereof.
Background
The multi-colour stone paint is made up of incompatible two-phase components through one-step spraying to obtain a heterogeneous paint with beautiful and multi-colour pattern. The two phase components of the multi-color elegant crystal stone paint are respectively a continuous phase and a disperse phase. The multi-color jac stone coating can be divided into two types of coatings, namely water-in-water coating and sand-in-water coating according to different disperse phases.
The coating amount of the water-in-water type multi-color elegant crystal stone coating is low (200-400 g/square meter), but the pattern layer is very thin, as if the pattern layer floats on the surface of the coating, so that the color point is stiff. The coating film of the water-in-water type multi-color elegant crystal stone coating is smooth, has far difference from the stereoscopic impression and surface frosting sense of real litchi surface and fire surface stone patterns, has poor imitation stone simulation degree, and has the factors of color mixing of colorful points through color paste, color difference among the colorful points in proportion, size and batch, and the like, so that the water-in-water type multi-color elegant crystal stone coating is extremely easy to generate batch-to-batch color difference in the construction application process, has common imitation stone simulation degree and is difficult to widely apply.
The multi-color elegant stone coating of the sand-in-water type is a coating which can show the three-dimensional sense of the patterns of litchi surfaces and fire-burned stone materials, and the main material contains sand and has thicker coating film. After spraying, the patterns and the modeling are integrated, so that the stone pattern has the hue sense, and simultaneously has the texture of the color sand on the surfaces of the litchi surface and the burnt surface stone. The stone imitation simulation degree of the multi-color stone coating of the water-in-sand type is high, and the multi-color stone coating is widely applied. However, the multi-color elegant stone coating of the water-coated sand type has higher imitation stone simulation degree and texture no matter whether the surface is burnt or the litchi surface is sprayed fully without exposing the bottom, and in the normal case, the multi-color elegant stone coating of the water-coated sand type needs to be sprayed twice to be sprayed fully without exposing the bottom. When the multi-color elegant crystal stone coating of the water-coated sand type is formed by one-step spray coating, the lamination degree of particles is thicker, the particles are not easy to dry, the film forming property is slow, cracking and cracking phenomena occur, especially, the phenomena that cracking, whitening and the like cannot be resisted easily after spraying occur in seasons with low air temperature and slow drying, the thickness of the coating is not easy to master by one-step forming, construction defects such as too large paint yield, uneven particles, large chromatic aberration and the like are more easily caused.
Therefore, the existing multi-color elegant stone coating of the sand-in-water type is required to be subjected to secondary molding construction, so that the coating quantity is high (1000-1500 g/square meter), the construction procedures are more, and the stability is poor.
Disclosure of Invention
In order to improve the stability of the multicolor jac stone coating and reduce the coating weight of the multicolor jac stone coating, the application provides the multicolor jac stone coating and a preparation method thereof, and the following technical scheme is adopted.
In a first aspect, a multi-color elegant stone coating is provided, the multi-color elegant stone coating comprises the following raw materials in parts by weight: 13-18 parts of protective glue solution, 30-38 parts of base paint, 25-35 parts of continuous phase, 12-15 parts of granulating solution, 15-30 parts of sintered color sand, 0.8-1.2 parts of cross-linking agent and 0.08-0.1 part of suspending agent; the protective glue solution comprises the following raw materials in parts by weight: 90-100 parts of deionized water, 10-15 parts of protective rubber powder and 1-2 parts of polymaleic anhydride; the base paint comprises the following raw materials in parts by weight: 90-100 parts of deionized water, 50-60 parts of silicone-acrylic emulsion, 10-15 parts of inorganic silicone resin, 4-6 parts of cellulose, 0.8-1.2 parts of dispersing agent, 0.5-1 part of defoamer, 1-3 parts of titanium dioxide and 5-7 parts of propylene glycol; the continuous phase comprises the following raw materials in parts by weight: 80-100 parts of deionized water, 180-200 parts of silicone-acrylate emulsion, 10-20 parts of organic-inorganic IPN hybrid resin, 8-10 parts of film forming auxiliary agent, 10-13 parts of polyvinyl alcohol, 1.5-3 parts of sterilization preservative and 1-2 parts of defoamer; the granulating liquid comprises the following raw materials in parts by weight: 50-70 parts of deionized water, 1-2 parts of organic bentonite and 2-4 parts of magnesium aluminum silicate.
Through adopting above-mentioned technical scheme, the multi-color elegant brilliant stone coating of this application disperses evenly, and once spray forming, and the coating weight is 400-600 g/. Square meter, and the coating after spray forming has good weatherability, stain resistance, acid and alkali resistance, does not have high low temperature colour difference, and construction convenience is better. After the preparation of the multi-color elegant crystal stone coating is finished, the multi-color elegant crystal stone coating is free of caking and uniformly dispersed in a container, and the water resistance range of the coating after spray molding is 260-300h; the acid resistance range is 255-300h; the alkali resistance range is 250-295h; the range of the artificial weather aging resistance is 3000-3500h; the heat resistance is excellent, and the high and low Wen Secha are avoided; the stain resistance grade is 1 grade (the solvent-free waterproof stain-resistant finish paint 2K of Sichuan polymer material Co., ltd. Has lotus leaf effect, and the stain resistance can reach 0 grade). The multi-color elegant stone coating provided by the application has the advantages that through the mutual synergistic effect among the raw materials, the construction is convenient and quick (color point one-time spraying), the imitation stone simulation degree is good, the color difference among batches is small, the weather resistance is excellent, the stain resistance is good, the color is fresh and flexible, the application range is wide, and the market demand is met.
In this application, inorganic sintering color sand is through the color particle that all-round parcel formed of protection glue solution and cellulose gelation reaction and weak hydrogen bond crosslinking reaction, and not only the parcel is even, and adhesive force is excellent, and shearing granulation stability is good, does not ooze the color, and colour distinctness of image is good moreover, soft butt joint between the particle color has soft definition and permeability, and whole imitative stone effect is three-dimensional, unique stone nature flexibility. And the polymaleic anhydride is added into the protective glue solution, so that the dispersion uniformity of the colorful cristobalite coating can be improved, and the prepared colorful cristobalite coating is free from caking and uniform in dispersion in a container. Meanwhile, the polymaleic anhydride and the cellulose are mutually cooperated, so that the adhesion force of the protective glue solution and the base paint on the surface of the sintered colored sand can be further improved, and the weather resistance of the multi-colored elegant crystal stone paint can be improved.
In addition, the addition of the polyvinyl alcohol in the continuous phase can not only improve the consistency of the continuous phase, but also can cooperate with the organic bentonite, the cellulose and the polymaleic anhydride to further improve the stability and the weather resistance of the multi-color elegant crystal stone coating.
