The common roller coating UV solid color primer is constructed by using a single-roller or double-roller coating machine, and because a paint film is uneven and has heavy roller marks, the solid color primer is easy to wear, so that two or three single-roller solid color primers or double-roller solid color primers are added, and then a transparent sanding primer is added to protect the solid color primer, so that the working procedures are increased, the working hours are prolonged, the integral efficiency and benefit are low, and the integral coating efficiency is reduced. Under the condition of spraying the large-surface paint, the flatness and the grindability of a paint film of the traditional PE solid-color primer can not meet the market requirements, and a large amount of organic solvent released by using the PE paint pollutes the atmosphere. Therefore, harmful substances volatilize in the production process, the health of a human body is seriously influenced, the production period is long, the problems of orange peels and the like are easily caused, and the manual grinding difficulty is very high.
In conclusion, a positive and reverse roller matte UV coating material which has the advantages of no VOC emission, environmental protection, high efficiency, energy conservation, and greatly improved leveling, fullness and hand feeling of a positive and reverse roller compared with a traditional flat roller positive and reverse roller is to be researched.
