Abstract

The invention provides an antibacterial offset printing UV (Ultraviolet) ink diluent, which comprises the following components in percentage by weight: 85-95 percent of epoxy acrylate resin, 4-14 percent of acrylic ester, 0.3-0.6 percent of benzil dimethyl ketal, 0.2-0.5 percent of 9,10-epoxystearic acid monooctyl ester and 0.1-0.2 percent of an inorganic antibacterial agent. The invention further provides a preparation method of the antibacterial offset printing UV ink diluent. The inorganic antibacterial agent is added into the offset printing UV ink diluent, so that the offset printing UV ink diluent is endowed with high antibacterial performance. The offset printing UV ink diluent is a paste adhesive object with very high viscosity, and the inorganic antibacterial agent can be effectively and uniformly dispersed into the offset printing UV ink diluent, so that the inorganic antibacterial agent can be uniformly distributed on a product after printing, the efficient antibacterial performance is brought into full play, the printing suitability of the offset printing UV ink diluent is not influenced, and the surface of the product is free from harsh feeling after printing.

Description

technical field [0001] The invention relates to an ink diluent, in particular to an antibacterial UV ink diluent for offset printing and a preparation method thereof. Background technique [0002] Ink thinner, also called varnish, is added to the ink to lighten the color, increase the brightness of the hue, and make the color brighter. Among them, the offset printing UV (ultraviolet light curing) ink thinner is a kind of ink thinner used in the fields of offset printing UV ink manufacturing and offset printing production. Offset UV ink diluent has good gloss and good printability, and can be used as an auxiliary agent for making offset UV ink. In the production process of offset printing, in order to meet the gloss requirements and color concentration of UV inks in different degrees, it is also necessary to add an appropriate amount of offset UV ink diluent. [0003] With the improvement of people's living standards, higher requirements are put forward for environmental qu...
