Abstract

The invention discloses a low temperature laser transfer coating which is characterized by being prepared from the following components in parts by weight: 20-30 parts of glycidyl methacrylate, 2-8 parts of epoxypropyl methacrylate, 10-25 parts of butyl acrylate, 20-30 parts of propylene glycol methyl ether acetate, 20-25 parts of propylene glycol monomethyl ether, 2-8 parts of nitrocotton, 0.5-2 parts of flatting agent, 1-5 parts of defoamer, 0.5-2 parts of PH adjustor and 0.2-1 part of benzoyl peroxide. According to the low temperature laser transfer coating disclosed by the invention, when a coated transfer membrane is subjected to mould pressing, the mould pressing temperature is low just at 130 DEG C, so that the mould pressing temperature is greatly reduced, the energy source is saved, and the coating is in accordance with the policy of energy conservation and emission reduction in China. The low temperature laser transfer coating is high in solid content and low in viscosity, and can be directly used. The coating is non-toxic, environment-friendly and low in content of volatile organic compounds (VOCs). Meanwhile, the obtained product has the characteristics of good laser effect and high glossiness.

Description

technical field [0001] The invention relates to a laser transfer coating, in particular to a low-temperature laser transfer coating and a preparation method of the low-temperature laser transfer coating. Background technique [0002] With the development of modern science and technology, various packaging materials continue to emerge. As a high-end packaging material, laser transfer paper has been welcomed by all walks of life since its inception. It is more and more widely used in the packaging field, and its consumption has also increased significantly year by year. However, the glass transition temperature of the traditional laser transfer paper coating is relatively high, which requires a high temperature of the plate roller during molding, and the holographic pattern on the laser master can be printed on the coating when it reaches 170-200°C. However, when the temperature of the plate roll is too high during molding, it is easy to cause tensile deformation of the base ...
