Abstract

The invention discloses a high-polarity UV coating material and a preparation method thereof, and belongs to the technical field of UV coating materials. The material is prepared from the following components in parts by weight: 35 to 45 parts of UV resin, 25 to 35 parts of reactive diluent, 0.05 to 0.2 part of defoaming agent, 0.05 to 0.3 part of flatting agent, 3 to 4 parts of photoinitiator, 0.1 to 0.5 part of dispersing agent, 15 to 20 parts of inorganic filler, 0.1 to 0.5 part of rheological additive and 5 to 10 parts of acrylic resin. The coating material disclosed by the invention is free of VOC emission, green, environment-friendly, efficient and energy-saving, the adhesive force to a base material and the adhesive force receiving capacity of the coating material are greatly improved compared with other UV coating materials, the requirements of consumers for high efficiency, energy conservation, environmental protection and high applicability can be met to a greater extent, and the coating material has remarkable market value.

Description

technical field [0001] The invention belongs to the technical field of UV coating materials, in particular to a high-polarity UV coating material and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, whether it is the country or the market demand, the demand for more and more companies for environmentally friendly coating materials is gradually increasing, and UV and water-based coating materials will be the future trend. The current UV paint is not only Only environmental protection and high efficiency and energy saving have been more and more used by many manufacturers. Based on high efficiency, energy saving and environmental protection, it has greater adhesion to the substrate and its ability to be adhered than other UV coating materials. The improvement can better improve the applicability of UV products and the higher demand of the market. [0003] It is difficult for general UV paint construction to achieve...
