In food, medicine, chemical industry, light textile and other related industries, PP plastic woven composite packaging is widely used, printing ink is required to print characters, patterns and the like on the PP plastic woven composite packaging, a special salivation composite technology is required, about 20% of printing ink factories processing the printing ink adopt general Polyurethane (PU) resin as raw materials, and the printing ink is characterized in that: the coating is applied to common film materials (such as OPP, BOPP, PET, NY, aluminizer and the like), has good adhesion fastness, bright color, environmental protection and no toxicity, and is resistant to boiling in water and cooking without problems. But when the adhesive is used for PP plastic woven composite packaging, especially when a salivation composite process is adopted, the adhesive force is difficult to meet the requirement. The chlorinated polypropylene resin (CPP) is still adopted by about 80 percent of domestic composite ink production plants as an ink bonding material, and the ink processed by taking the chlorinated polypropylene resin as a base material is characterized in that: the chlorinated polypropylene ink can be used for films such as BOPP, CPP, PE and the like, has good adhesive force, and particularly has good compounding fastness when a casting compounding process is adopted. Secondly, the printing ink can not print film materials such as PET, NY, aluminized films and the like due to adhesive force. ③ the chlorine contained in the material and does not meet the requirement of halogen limitation. Fourthly, the steamed noodles can not be used for sterilization and packaging because of the intolerance of water boiling and the steaming. The chlorinated polypropylene resin is dissolved in xylene, toluene, acetone and butanone for use in producing ink, and these solvents have great influence on operator and environment. Secondly, high-toxicity carbon tetrachloride or trichloromethane solvent and highly toxic chlorine gas are used in the production of chlorinated polypropylene, and the problems of safety and environmental protection in the production process are difficult to solve. And thirdly, the raw materials are in short supply due to the fact that manufacturers are not environment-friendly, the price is high, and the method is difficult to be suitable for ink production and application. Therefore, the development of the polyurethane resin composition for the salivation composite ink is urgently needed by the market and is driven by safety and environmental protection.
