Coating for paper cards and use method thereof

Abstract

The invention discloses a coating for paper cards. The coating is prepared from the following raw materials in parts by weight: 7000 to 8000 parts of purified water, 140 to 150 parts of pink pigment,150 to 160 parts of yellow pigment, 100 to 120 parts of bright red pigment, 80 to 90 parts of lemon yellow pigment, 50 to 60 parts of white pigment, 10 to 20 parts of black pigment, 10 to 20 parts ofdark blue pigment, 250 to 260 parts of a thickening agent, 260 to 280 parts of mucilage, 1200 to 1230 parts of solid slurry, 5 to 10 parts of melamine, 100 to 200 parts of UV light-cured aromatic urethane acrylate and 100 to 200 parts of salty-fresh water junction oyster shell powder. The invention further provides a use method of the coating. The use method comprises the following steps that during spraying, finished products are cut after cards are printed; every 350 cards are stacked and flatly clamped along a vertical direction through a pneumatic clamp; and a color coating blended in steps is evenly sprayed on the four sides of a pneumatic sprinkling can, wherein spraying time is 60 seconds, so the cards sprayed with the paint are obtained. According to the invention, the problem of low yield caused by non-uniform staining, infirmness and difficulty in spraying of the coating in the prior art is solved, and the technical effect of improving the yield of products is achieved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a coating for paper cards, in particular to a coating for paper cards and a use method thereof. Background technique [0002] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called coating film, also known ...
