Chromatic printing production process of raised table

Abstract

The invention provides a chromatic printing production process of a raised table, relating to the technical field of three-dimensional stain paint production of sheets, such as a density fiberboard, a glass magnesium board, a shaving board and the like. A primer is sprayed on the surface of a deburred raised plane table. The dried raised plane table is placed on an operating platform surface of a positive / negative pressure plastic-absorbing machine. A PET (Poly Ethylene Terephthalate) transfer film is covered on the raised plane table, and vacuum plastic-absorbing transfer is carried out on the PET transfer film covered on the raised plane table. After removing the PET transfer film, PU (Poly Urethane) anti-yellowing gloss oil is sprayed on the surface of the raised plane table and is molded by roasting. The PET transfer film (which has the character of no stretching after being heated) is directly used and transfer is carried out by using the primer (which not only replaces a suction plastic adhesive in a transfer technique but also causes a transferred product to have another color besides the color of the transfer film, namely the raised part is in the color of the transfer film and the concave part is in a sprayed bottom color) through the positive / negative pressure plastic-absorbing machine. Compared with the traditional production process of the same type of the products, the labor cost and the raw material cost are greatly reduced, the chromatic aberration is avoided and the yield is improved; and meanwhile, the paint consumption is saved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional color pattern production of board materials such as density boards, glass magnesium boards, and particle boards. Background technique [0002] The general method of the existing transfer printing plate process is: first spray plastic on the plate, and then transfer with PVC transfer film. This process can only transfer the color on the transfer film to the product (protruding surface and concave part The surface is the color on the transfer film). [0003] There is also a production process of color registration on the relief board by hand. First, the first color paint is made on the entire surface of the relief board, and then the second color paint is fully covered on the entire relief board, and the relief board is removed by manual grinding. Protrude the second color paint on the surface, so that the original first color paint is exposed, and then spray the top coat. Due to manual ...

Problems solved by technology

Due to manual polishing, the products produced cannot avoid color difference, the yield rate is low, and the process is cumbersome, and the labor cost and raw material cost are very high
