[0024]

[0025] Table 2 performance index of the present invention

[0026]

[0027] According to the formula in Table 1, the matte UV coating material for front and back rollers is prepared by the following method: uniformly disperse UV resin, reactive diluent, and photoinitiator at a low speed in sequence, and disperse the dispersant, leveling agent, and defoamer at a low speed in sequence. After dispersing for 5 minutes (500 rpm), add fillers, rheological additives, and matting agents and disperse at high speed for 30 minutes (1000 rpm) until the fineness is ≤30 microns. After filtering, the front and reverse roller matte UV coating materials can be prepared .

Abstract

The invention discloses a forward and reverse roller matte UV coating material and a preparation method thereof. The material comprises the following components in parts by weight: 35-45 parts of UV resin, 25-35 parts of an active diluent, 0.05-0.2 part of an antifoaming agent, 0.05-0.3 part of a leveling agent, 3-4 parts of a photoinitiator, 0.1-0.5 part of a dispersing agent, 8-15 parts of an inorganic filler, 0.1-0.5 part of a rheological agent and 10-20 parts of a delustering agent. The coating material has the advantages of no VOC emission, environmental protection, high efficiency, energy saving, great improvement of the leveling, fullness and hand feeling of forward and reverse roller coating compared with traditional flat rollers and forward and reverse rollers, great meeting of consumers' demands of high efficiency, energy saving, environmental protection and beauty, and substantial market values.

Description

technical field [0001] The invention belongs to the technical field of UV coating materials, in particular to a matte UV coating material for forward and reverse rolls 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 Environmental protection and high efficiency and energy saving have been more and more applied by many manufacturers. Based on high efficiency, energy saving and environmental protection, the surface of forward and reverse roller UV coating matte decoration materials is more plump and smoother than that of traditional flat roller coating. Delicacy and softness meet the higher demand of the market. [0003] Generally, the UV solid-color primer...
