Gravure benzene-free solvent ink

Abstract

The invention discloses a gravure benzene-free solvent ink, which comprises the following components by weight: 8-25 parts of main resin, 3-8 parts of modified resin, 0.4-1.1 parts of polyethylene wax, 10-30 parts of pigment, 8-15 parts of a mixed solvent, 1-8 parts of kaolin, 3-7 parts of polyvinyl butyral, 0.2-0.6 part of erucic acid wax, 2-6 parts of active agent, 1-4 parts of stabilizer, 0.5-1.2 parts of coupling agent, and 0.5-1.2 parts of reinforcing agent. The gravure benzene-free solvent ink provided by the invention has low cost, high performance, and wide applicability, does not contain toxic substances such as benzene, is more environmentally friendly, and avoids affecting the physical and mental health of workers.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a benzene-free solvent-free gravure ink. Background technique [0002] Most of the flexible packaging printing industry involving food and daily necessities packaging, there are two types of composite inks of the same type that are currently used the most in China. One is chlorinated polypropylene resin, EVA resin and chlorinated ether resin as connecting resins, and toluene or esters as connecting resins. The main solvent system ink; the other is a solvent system ink based on esters or alcohols with polyurethane resin and vinyl resin as the connecting resin. Although this type of ink can be made more and more exquisite and prosperous in packaging and printing, most inks use non-environmental and toxic solvents such as toluene in production or printing, which not only affects the physical and mental health of workers It is also not applicable to new environmental protection regulat...

Problems solved by technology

Although this type of ink can be made more and more exquisite and prosperous in packaging and printing, most inks use non-environmental and toxic solvents such as toluene in production or printing, which not only affects the physical and mental health of workers It is also not applicable to new environmental regulations and policies, and it will also produce relatively large solvent residual odor on printed products, causing pollution to packaging items
