The solvent type is basically a terpineol system, occupies a main position, has good storage stability and good adhesive force, but is accompanied with the attention and requirements of people on environmental protection and health, finds one of the disadvantages of the terpineol system product, namely, has large smell and certain harm to the environment and human body, the ink system is easy to generate bubbles, the problem of the bubbles can be solved by adding a defoaming agent, the pigment loading amount of the ink adjusting oil is low, the preparation of the ink with high solid content is not facilitated, meanwhile, a screen printing plate and glass for printing are required to be cleaned by using a special cleaning agent, and the pollution of underground water is easily caused by random discharge; moreover, the terpineol is mainly extracted from natural substances, the production capacity is limited, the price of the terpineol is high, and the cost pressure is also applied to production enterprises. Therefore, the varnish capable of replacing a terpineol system is developed, has the advantages of low odor, low volatilization, easiness in cleaning and the like, and can well solve the problem of the conventional solvent type varnish.
The terpineol system is used as a mature product, companies have few researches on the product, main hot spots are concentrated on the water-based varnish, but the current water-based varnish still has the problems of poor storage stability, large residual ash content after high-temperature sintering and the like, and cannot completely replace solvent-based products in a short time, so the terpineol system has great significance for optimizing the current terpineol system product which is the mainstream.
