Abstract

The invention provides a UV (ultraviolet) ink bridging agent and application thereof. The bridging agent comprises resin, a curing agent and a solvent, wherein the resin comprises the following components in percentage by weight: 30-50% of alkyd resin, 10-30% of cellulose nitrate, 20-30% of ester solvent, 0-1.5% of antioxidant, 0-0.8% of tetrafluoroethylene gas-phase wax, 3-8% of diethylene glycol monobutyl ether and 0-1% of leveling agent; the curing agent comprises the following components in percentage by weight: 20-80% of low free TDI (toluene diisocyanate) curing agent raw material and 20-80% of ethyl acetate; and the solvent comprises the following components in percentage by weight: 70-90% of ethyl acetate, 8-20% of ethylene glycol monoethyl ether acetate and 1-10% of diethylene glycol monobutyl ether. The bridging agent provided by the invention is used for the UV ink printing of plates and can effectively enhance the adhesive force of ink on the plates.

Description

technical field [0001] The invention relates to the field of ink printing, in particular to a UV ink bridging agent and its application. Background technique [0002] Most of the current furniture panels use paint for color matching or drawing. However, heavy metals are often contained in paints, such as chrome yellow, dark chrome yellow, cadmium red, molybdenum chrome red and other pigments in colored paints, and driers such as lead epoxy acid and lead isooctanoate are mixed in the preparation process. Therefore, these furniture containing heavy metal paints have the risk of excessive heavy metals. [0003] UV ink is an environmentally friendly ink that does not use solvents, has fast drying speed, good gloss, bright colors, water resistance, solvent resistance and abrasion resistance. Its application scope involves many industries such as furniture. In order to solve the problem of excessive heavy metals in furniture with excessive paint, at present, some researchers use...
