Embodiment 1

[0008] Example 1, a UV transfer printing process for wall decorative panels, including the following steps: (1) Treating the substrate: sealing the back of the substrate with UV penetration, and using a 40-120-mesh sander to sand the surface of the substrate to determine the thickness. Light, to ensure the basic thickness, dust cleaning machine to remove dust, then roll coating UV penetration and curing, sanding with 240-320 mesh belt, dust cleaning machine to remove dust; then roll coating UV primer, UV curing, using 240-320 Purpose Abrasive belt sanding, dust cleaning machine to remove dust; (2) Front surface of roller coating: roll coating UV board glue on the front surface of the substrate, UV semi-curing, glue on the roller coating film, and send it to the transfer machine; (3) Transfer Printing: According to the color depth of the transfer film, determine the number of UV curing lamps to be turned on, attach the transfer film to the substrate after step (2) through the tr...

Embodiment 2

[0009] Example 2, in the UV transfer printing process of the wall decoration board described in Example 1: the substrate is 100% asbestos-free. The base material is 100% free of asbestos, and is a new type of green environmental protection product.

Embodiment 3

[0010] Example 3, the UV transfer printing process of the wall decorative board described in Example 1 or 2: includes the following steps: (1) Treating the substrate: the back is sealed with UV penetration to prevent moisture absorption; the front is covered with a 40-mesh abrasive belt The surface of the substrate is sanded with a fixed thickness to ensure that the thickness of the same batch of substrates is consistent. The dust cleaning machine removes the dust, and then the roller coats UV penetration and curing (the function is to seal and improve the adhesion of the paint film), and sand with a 240-mesh abrasive belt. Dust cleaning machine removes dust, then roller coats UV primer, UV cures, and sands with 240-mesh abrasive belt (the function is to ensure smooth surface, further improve the adhesion of the subsequent paint film, and perform secondary sealing on the surface of the substrate), Dust cleaning machine to remove dust; (2) Front side of roller coating: UV glue i...

Abstract

The invention relates to a UV transfer printing process for a wall decorative sheet. The process comprises the following steps: (1) processing a substrate; (2) carrying out roller painting on the front surface; (3) carrying out transfer printing; and (4) carrying out film covering. No harmful gas such as formaldehyde and benzene are released in the process, so that the process is green and environment-friendly. By adopting a product with inorganic and fluorocarbon coatings, the anti-ultraviolet property of the product in an application of an exterior wall is improved greatly; the product is smooth in surface and is coated with a special antibacterial coating, so that bacteria are unlikely to breed, and the product shows an excellent antibacterial performance; a panel is high in areal density and has a good sound isolating property, and a cavity is formed in a mounting system to achieve a sound absorbing effect; by adopting a special antistatic coating, the surface of the product has the antistatic function; the cold and hot expansion shrinkage coefficient is small, and the size of the panel is scarcely changed as the temperature changes. The process provided by the invention is good in durability, light in weight, easy to clean, energy-saving and environment-friendly, easy to process, waterproof and excellent in drug resistance.

Description

technical field [0001] The invention relates to the technical field of transfer printing, in particular to a UV transfer printing process for a wall decoration board. Background technique [0002] Thermal transfer printing is a technology that prints the pattern on the heat-resistant adhesive paper, and prints the pattern of the ink layer on the finished material by heating and pressing. Even if it is a multi-color pattern, since the transfer operation is only one process, customers can shorten the printing pattern operation and reduce the loss of materials (finished products) due to printing errors. The use of thermal transfer film printing can form multi-color clusters at one time, without the need for color registration, and simple equipment can also print realistic patterns. However, the existing transfer printing technology products have defects in durability, waterproof, anti-corrosion, anti-bacterial, and anti-ultraviolet rays, which cannot meet the requirements of e...
