Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application more clearly apparent, the present application is further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The embodiment of the application provides a preparation method of a decorative plate, which comprises the following steps:
s01, forming a colored paint film on the surface of water according to the pre-designed texture pattern; wherein, the colored paint film is formed by blending at least two kinds of oily colored paints;
and S02, immersing the substrate into a mixed system of the color paint film and water to form a decorative coating on the surface of the substrate.
According to the preparation method of the decorative plate, the colored paint film is formed on the surface of water according to the pre-designed texture pattern, and then the substrate is immersed into the mixed system of the colored paint film and the water to form the decorative coating on the surface of the substrate. The method forms the pre-designed texture pattern on the water surface and then coats the substrate, and the surface effect of the decorative coating can be controlled by adjusting the texture pattern formed on the water surface by each oily colored paint, so that the method is favorable for improving the product yield, is suitable for forming the texture patterns with various effects, and has wide application prospect; moreover, due to the fluidity of water, the naturalness of the texture pattern of the decorative coating is improved to a certain extent, the colorful, natural and vivid surface effects such as fantasy colors, stone imitation and the like can be formed, the requirements of people on the decorative effect of the building outer wall are met, and the decorative coating has great potential commercial value.
Different from the dip-coating process of the existing decorative plate, the preparation method provided by the embodiment of the application is easy to form the decorative coating with rich and colorful texture patterns on the surface of the substrate, and is simple and convenient to operate and high in controllability. Unlike the existing method for forming the coating with the texture by adopting the ink-jet printing process, the method provided by the embodiment of the application is simple and convenient to operate and does not need to use expensive ink-jet printing equipment.
Specifically, in step S01, a paint film is formed on the surface of water, and the paint film is formed by fusing at least two kinds of oil paints, so that the paint film has a pre-designed texture pattern.
Because the oily colored paint and the water are not mutually soluble and the density of the oily colored paint is less than that of the water, the oily colored paints are mutually blended, and a colored paint film is formed on the surface of the water.
In the present specification, blending means interfusion, and specifically means that the contact interface between the oil-based paints in contact with each other is blurred, or even the two oil-based paints are completely mixed. The mutual contact can occur between two oily paints or between three oily paints.
The choice of the type of oil-based pigmented paint influences the overall properties of the subsequently formed decorative coating, such as weather resistance. In some embodiments, the oily color paint is selected from fluorocarbon paint, which is insoluble in water and has good weather resistance, so that the decorative coating has good surface effect and also has the quality guarantee period of more than 20 years of the paint film of the fluorocarbon paint. The specific process for forming a paint film on the surface of water can be carried out by referring to the conventional operations in the field, and in some embodiments, at least two oily paints are sprayed on the surface of water in the step of forming a paint film on the surface of water. The spraying method can avoid the direct contact of the deposition tool and the water surface, is easy to operate, can avoid various oily colored paints from sinking into the water bottom in the construction process, and ensures that colored paint films formed on the water surface of the oily colored paints can perfectly float on the clear water surface, thereby improving the quality of the decorative coating. In one embodiment, at least two oily paints are sprayed on the surface of water by adjusting the ambient air pressure to a breeze state. By adjusting the ambient air pressure to be in a breeze state, patterns which are gradually changed and dissolved are formed among the oily colored paints, and the production efficiency is improved to a certain extent.
The pre-designed texture pattern is a sketch of the surface effect of the decorative coating, the sequence and the position of each oily colored paint sprayed on the water surface refer to the pre-designed texture pattern, and the texture pattern of the colored paint film formed on the water surface by each oily colored paint is the same as or similar to the pre-designed texture pattern, so that the surface effect of the decorative coating is controlled. In some embodiments, the pre-designed texture pattern is formed by matching four colors of red, white, blue, black and the like, and the white paint, the black paint, the blue paint and the red paint are sequentially deposited on the surface of the water in the sequence of white → black → blue → red during coating.
In order to promote the mutual fusion of the oil-based colored paints and to adjust the textures of the colored paint films so as to further optimize the surface effect of the decorative coating and make the textures more natural or richer, the colored paint films formed by the oil-based colored paints are often subjected to post-treatment after the step of forming the colored paint films on the surface of water.
In some embodiments, after the step of forming the color paint film on the surface of the water, the color paint film is blown with a wind gun and/or drips at the edge of the color paint film. In one embodiment, after forming the paint film on the water surface, the air pressure is adjusted to a gentle breeze state, and the paint film is blown by an air gun to promote the oil paints to be blended and fine-tune the texture of the oil paints on the water surface. In another embodiment, after the colored paint film is formed on the surface of water, water is dripped on the edge of the colored paint film formed by each oily colored paint, for example, water is dripped on the edge of the liquid level of a container for bearing water and each oily colored paint, so as to adjust the texture pattern formed on the surface of water by each oily colored paint, and make the texture pattern more natural and richer.
In order to adjust the interface performance of the oil paint and water, the water or the oil paint can contain a surfactant to improve the quality of the decorative coating. In some embodiments, a defoaming agent is added into the water before the step of forming the colored paint film on the surface of the water, so as to prevent the formed colored paint film from generating bubbles to influence the appearance of the decorative coating, thereby improving the quality of the decorative coating. In the specific embodiment, the defoaming agent is sprayed on the surface of the water before the step of forming the colored paint film on the surface of the water, the method is convenient to operate, and the using amount of the defoaming agent can be greatly reduced. The defoaming agent can be selected from conventional defoaming agents in the art, including but not limited to silicone defoaming agents, acrylic defoaming agents, modified acrylic defoaming agents, and the like.
In step S02, the substrate is dipped in a mixed system of a color paint film and water to form a decorative coating on the surface of the substrate.
And immersing the substrate into a mixed system of the color paint film and water, so that the color paint film contacts the substrate and is pressed on the substrate by the reverse pressure of the water, thereby forming the decorative coating on the substrate. Due to the fluidity of water, the formed decorative coating has natural and vivid texture and has the surface effects of color illusion and stone imitation.
The substrate serves as a carrier for forming the decorative coating and may be selected from conventional substrates in the art, such as in some embodiments, calcium silicate board, gypsum board, or aluminum plastic board. In the specific embodiment, the substrate is selected from calcium silicate boards and is used for preparing decorative boards of building outer walls.
The way in which the substrate is immersed in the mixed system influences the adhesion effect of the paint film on the substrate and the surface effect of the decorative coating. In some embodiments, the substrate is immersed in the mixing system such that the substrate is at an angle of 30 ° to 80 ° to the liquid surface of the mixing system. The substrate is immersed into the mixed system under the angle of 30-80 degrees with the liquid surface of the mixed system, so that the paint film formed on the water surface by each oily paint can be promoted to be fully contacted and adhered with the substrate, and the operation is simple and convenient. In a specific embodiment, the substrate and the color paint film form an included angle of 60 degrees.
On the basis of the previous embodiment, the substrate is completely immersed into the mixing system, and the substrate is far away from the mixing system after being shaken. After the substrate is immersed into the mixed system, the substrate is shaken, so that the texture of the decorative coating can be further enriched.
The time for immersing the substrate into the mixed system refers to the thickness of the decorative coating, the viscosity of the oily paint and the drying time of the coating, and within the optional drying time range of the coating, when the viscosity of the oily paint is fixed, the higher the thickness of the decorative coating is, the longer the time for immersing the substrate into the mixed system is. In some embodiments, the decorative coating has a thickness of 30-40 microns, which is effective to coordinate coating durability and manufacturing costs. In one embodiment, the substrate is immersed in the mixing system for a period of 2 minutes.
The degree of the substrate immersed in the mixed system can be flexibly adjusted according to specific surface effects, and the substrate can be completely immersed in the mixed system or partially immersed in the mixed system. In some embodiments, the substrate is dipped into the paint film and the paint film is pressed onto the substrate by the counter pressure of water.
In order to further improve the surface effect and weather resistance of the decorative coating, the substrate is often subjected to a pretreatment before the step of immersing the substrate in a mixed system of a color paint film and water, and a post-treatment of the decorative coating.
In some embodiments, a primer coating is formed on the substrate prior to the step of immersing the substrate in the mixed system of the color paint film and water to seal and fill surface defects of the substrate and enhance the surface effect of the decorative coating. In particular embodiments, the primer coating thickness is 40-50 microns to ensure that the primer coating completely occludes and fills surface defects of the substrate.
The method of forming the primer coating on the substrate may refer to a conventional operation in the art such that the surface defects of the substrate are completely closed and filled. The primer coating layer is made of a primer material that is conventional in the art, and in some embodiments, the primer coating layer is made of at least one material selected from an acrylic paint, a fluorocarbon paint, an epoxy paint and a polyurethane paint, preferably a fluorocarbon paint, a polyurethane paint or an epoxy paint, and the fluorocarbon paint has good weather resistance and the epoxy paint and the polyurethane paint are tightly bonded to the substrate. In a specific embodiment, the material for forming the primer coating is selected from fluorocarbon paint, so that the formed primer coating is compatible with the decorative coating, the adhesion effect of the color paint film on the substrate and the weather resistance of the coating are further improved, and the surface effect and the shelf life of the coating are improved.
In some embodiments, after forming the decorative coating on the surface of the substrate, an overprint varnish coating is formed on the decorative coating. The finishing paint coating is transparent, resistant to ultraviolet rays and chemical corrosion, has high gloss and high gloss retention, plays a role in decorating and protecting the decorative coating, and is beneficial to further prolonging the quality guarantee period of the decorative coating. In a specific embodiment, the thickness of the finishing paint coating is 25-35 microns, and within the thickness range, the coating has high transparency and excellent protection effect on the decorative coating.
The method of forming the finishing coat on the decorative coating can refer to the routine operation in the field, so that the decorative coating is completely covered by the finishing coat. The material forming the overprint varnish coating may be selected from conventional overprint varnishes known in the art, and in some embodiments, the material forming the overprint varnish coating is selected from fluorocarbon coatings and/or polyurethane coatings. In the specific embodiment, the material for forming the finishing paint coating is fluorocarbon coating, and the fluorocarbon coating has excellent weather resistance and good compatibility with the decorative coating, and is favorable for improving the operability of forming the finishing paint coating on the decorative coating.
