[0016] The main material used in the composite ink of this scheme is benzene-free and ketone-free polyurethane resin. When the residue is detected, it does not contain halogen and heavy metals after testing, which meets environmental protection requirements. In addition, the solubility of polyurethane resin is good, and the solubility of benzene-free and ketone-free polyurethane resin is good, which can fully improve the ink reconstitution performance. After the printing ink is diluted by 10%, the printing can reach the concentration of other existing inks, and the customer's printing transfer rate is increased by 10% , Reflects a more excellent shallow screen printing effect. In addition, using distilled water as a slow-drying auxiliary, the ink printing residue does not contain polymer solvents, and the total printing residue is controlled at 2 mg / square, which fully meets the GT-9685 national testing standard.
