Printing ink

Abstract

The invention provides a sort of ink manufactured by raw materials with the following mass percent: 10-15 percent of butadiene acrylonitrile rubber, 9-15 percent of neoprene, 5-10 percent of acetone, 5-10 percent of toluene, 10-15 percent of glycol butyl et her, 9-15 percent of linseed oil, 5-11 percent of silicon oil, 1-5 percent of titanate coupling agent, 10-25 percent of pigment, 1-4 percent of polyethylene wax, and 0.5-3 percent of aluminum stearate; the ink of the invention is mainly applicable to printing of various plastic material carriers and is provided with high adhesive attraction and good adhesive effect. In the applying facet, superficial treatment is not needed to be carried out to the plastic material carrier when used; printing can be carried out directly, thus guaranteeing good printing effect.

Description

technical field [0001] The invention belongs to the field of ink, and relates to an ink suitable for printing various plastic products. Background technique [0002] Ink is an important material used for printing packaging materials. It is a viscous fluid substance with a certain color. It expresses patterns and characters on the substrate through printing. The ink is mainly composed of pigments, binders, fillers and auxiliary materials to form a uniform mixture. [0003] Plastic inks on the market are inks formulated for a certain type of plastic, and cannot be used for plastics and other substances of various materials. Polyethylene and polypropylene materials have high crystallinity, strong solvent resistance, low surface polarity and surface energy, and the coating film is difficult to adhere. Surface treatment must be carried out before printing to achieve the adhesion effect. The process is complicated and the effect is not ideal. Contents of the invention [0004]...
