Description
Technical Field
The application relates to the technical field of coatings, in particular to a novel colorful kyanite coating and a preparation method thereof.
Background
The multi-color elegant crystal stone coating is a heterogeneous coating which is composed of incompatible two-phase components and can obtain beautiful and colorful patterns through one-time spraying. The two-phase components of the polychlorinated elegance crystal coating are respectively a continuous phase and a disperse phase. The polychlorinated granite paint can be divided into two types of water-in-water and sand-in-water paint according to different dispersed phases.
The water-in-water type colorful quartzite coating has lower coating weight (200-400 g/square meter) but has a thin pattern layer which appears as if the coating surface is floated, so that the color point is rigid. The coating film of the water-in-water type multicolor elegant crystal coating is smooth, has a far difference with the stereoscopic impression and the frosted surface feel of the stone patterns of the real litchi surface and the burnt surface, and has poor imitation stone degree, and in addition, the colorful dots are subjected to color mixing by color paste, the proportion of the colorful dots, the difference between different batches and the like, so that the batch-to-batch color difference is easy to occur in the construction application process of the water-in-water type multicolor elegant crystal coating, and the imitation stone degree is general and is difficult to be widely applied.
The water-coated sand type colorful elegant crystal stone coating is a coating capable of presenting the three-dimensional sense of patterns of a litchi surface and a fired surface stone material, and the main material of the coating contains sand, so that the coating film is thicker. After spraying, the patterns and the modeling are integrated, so that the stone has the color sense of the patterns of the stone, and also has the texture of the color sand on the surfaces of the litchi surface and the burnt stone. The water-coated sand type colorful elegant spar coating has high stone imitation degree and is widely applied. However, the water-in-sand type colorful elegant crystal stone coating can have higher stone simulation degree and texture only by fully spraying and not exposing the bottom whether the fire surface or the litchi surface is the fire surface, and under the normal condition, the water-in-sand type colorful elegant crystal stone coating can be fully sprayed and not exposing the bottom only by adopting two times of spraying. When the water-coated sand type colorful elegant crystal stone coating is formed by one-step spraying, the lamination degree of particles is thicker, the particles are not easy to dry, the film forming property is slow, and the phenomena of cracking and cracking are caused, especially the phenomena of irresistibility such as cracking, whitening and the like are more easy to occur after spraying in seasons with low temperature and slow drying, and the thickness of the coating is not easy to master by one-step forming, so that construction defects are more easy to cause, such as too large paint output, uneven particles, larger color difference and the like.
Therefore, the existing multi-color Yayan spar coating of the sand-in-water type must adopt secondary forming construction, so that the coating quantity is higher (1000-1500 g/square meter), the construction procedures are more, and the stability is poorer.
Disclosure of Invention
In order to improve the stability of the colorful elegant crystal stone coating and reduce the coating amount of the colorful elegant crystal stone coating, the application provides a novel colorful elegant crystal stone coating and a preparation method thereof, and the following technical scheme is adopted.
The first aspect provides a novel colorful elegant crystal coating, which 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 liquid, 15-30 parts of calcined colored 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 defoaming agent, 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-acrylic emulsion, 10-20 parts of organic-inorganic IPN hybrid resin, 8-10 parts of film-forming additive, 10-13 parts of polyvinyl alcohol, 1.5-3 parts of bactericidal preservative and 1-2 parts of defoaming agent; the granulation 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.
By adopting the technical scheme, the novel multi-color elegant crystal stone coating is uniformly dispersed and is formed by spraying once, the coating weight is 400-600 g/square meter, and the coating formed by spraying has excellent weather resistance, stain resistance, acid and alkali resistance, no high and low temperature color difference and better construction convenience. After the preparation of the polychrome elegant crystal stone coating is finished, no agglomeration exists in a container, the dispersion is uniform, and the water resistance range of a coating after spray forming is 260-300h; the acid resistance range is 255-300h; the alkali resistance range is 250-295h; the artificial weather aging resistance range is 3000-3500h; the temperature resistance is excellent, and high and low temperature color difference is avoided; the stain resistance grade is 1 grade (2K solvent-free waterproof stain resistant scratch resistant finish paint of Sichuan coating high molecular material Co., ltd. Has lotus leaf effect, and the stain resistance can reach 0 grade). The utility model provides a novel various elegant brilliant stone coating is through the mutual synergism between each raw materials for its construction is convenient quick (the spraying of coloured silk one shot), imitative stone fidelity is good, batch colour difference is little, the weatherability is excellent, the stain resistance is good, the bright mirror of colour is nimble, has extensive range of application, accords with the market demand.
In this application, the inorganic colored sand that calcines is through the all-round colored particle of parcel formation of protection glue solution and cellulose gelling reaction and weak hydrogen bond cross-linking reaction, and not only the parcel is even, and the adhesive force is excellent, and it is good to cut granulation stability, and the non-bleeding, and the colour distinctness is good moreover, soft butt joint between the particle color has soft definition and permeability, and whole imitative stone effect is three-dimensional, has stone material nature flexibility alone. And the polymaleic anhydride is added into the protective glue solution, so that the dispersion uniformity of the polychrome elegant crystal stone coating can be improved, and the prepared polychrome elegant crystal stone coating is free of agglomeration and is uniformly dispersed in a container. Meanwhile, the polymaleic anhydride and the cellulose are synergistic, so that the adhesive force of the protective glue solution and the base paint on the surface of the calcined colored sand can be further improved, and the weather resistance of the multi-color elegant crystal coating can be improved.
In addition, the addition of the polyvinyl alcohol in the continuous phase can improve the consistency of the continuous phase, and meanwhile, the polyvinyl alcohol can be cooperated with organic bentonite, cellulose and polymaleic anhydride, so that the stability and weather resistance of the colorful elegant spar coating are further improved.
Optionally, the protective glue solution is prepared by the following method: adding the protective glue powder into deionized water, stirring until the protective glue powder is uniformly mixed, then adding the polymaleic anhydride under the stirring condition, and stirring for 30-40min to obtain the protective glue solution.
