Abstract

The invention discloses UV curing ink for printing PE materials. The UV curing ink is prepared from, by weight, 18-29 parts of connecting material prepolymer, 50-60 parts of diluting monomers, 6-10 parts of photoinitiators, 5-12 parts of filler, 10-13 parts of additives and 12-15 parts of pigment. The UV curing ink for printing the PE materials is easy and convenient to prepare, environmentally friendly, rapid in curing speed, capable of keeping good adhesive force with the PE materials and tolerating 1800 ppm peracetic acid solution high-temperature soaking and sterilization treatment, and wide in market application prospect.

Description

technical field [0001] The invention relates to the technical field of ink preparation, in particular to a UV curable ink used for printing PE materials. Background technique [0002] UV curable ink is a new type of environmentally friendly ink that can be cured rapidly under ultraviolet light. Since the solvent in traditional ink is replaced by diluent monomer, there is no organic solvent volatilization after the film layer is cured, which complies with environmental protection requirements. In addition, UV curable ink has the characteristics of instant curing, which meets the market demand and has broad application prospects. [0003] In recent years, with the development of society, polyethylene (PE) materials have been used more and more because of their excellent low temperature resistance, good chemical stability, and acid and alkali corrosion resistance. As the national environmental protection policy becomes more and more stringent, some PE materials must be sterili...
