Problems solved by technology

[0003] The commonly used mirror coating in the prior art is the coating of lime-calcium system. The shortcoming of this kind of coating is that the mirror effect of the coating formed by it is poor, and the coating of gray-calcium system is sprayed on the carrier, and it needs to be cleaned before the coating is cured. The paint is scraped flat, but the time for scraping the light is very short, which is not conducive to the production of large-area coatings

Abstract

The invention belongs to the field of materials, and discloses a coating with a mirror surface effect and a preparation method of the coating. The coating includes an emulstion and filler, wherein filler comprises light calcium carbonate and barium sulfate, and the emulsion is selected from at least one of acrylic emulsion, polyvinyl acetate emulsion, acrylate emulsion or styrene-butadiene emulsion. The coating also comprises cellulose and water. Based on the light calcium carbonate, barium sulfate and emulsion, the coating is coated on the surface of equipment in batches, and a coating layerformed after curing has a good mirror surface effect; in addition, cellulose and water are added into the coating, so that the opening time of the coating can be prolonged, and a large-area coating with a mirror surface effect can be prepared.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a coating with a mirror effect and a preparation method thereof. Background technique [0002] Mirror coating means that the coating is applied in batches on the carrier, such as wood, plastic, metal and other carriers, and then flattened and cured. The formed coating has a mirror effect, that is, the formed coating has high gloss or high reflectivity. Mirror coatings can be widely used in indoor and outdoor decoration. [0003] The commonly used mirror coating in the prior art is the coating of lime-calcium system. The shortcoming of this kind of coating is that the mirror effect of the coating formed by it is poor, and the coating of gray-calcium system is sprayed on the carrier, and it needs to be cleaned before the coating is cured. The coating is scraped flat, but the time for flattening and emitting light is very short, which is not conducive to making large-area coatings. [000...
