Problems solved by technology

At present, the printing ink used for extrusion compounding in China is the ink of the ethylene / vinyl acetate copolymer (EVA) resin system using toluene as the solvent. This ink is only suitable for PE extrusion compounding. The composite strength is only 0.1-0.3N / 15mm, which is far from meeting the standard requirement of 1.0N / 15mm composite strength for packaging products
During use, solvents such as toluene will volatilize, causing air pollution. During the printing production process, it will be harmful to the health of employees, and there will be residual benzene solvents in packaging products that will pollute food.

Abstract

The invention discloses an extrusion composite ink and a preparation method thereof. The ink consists of the following material: modified chlorinated-EVA resin, modified chlorinated polypropylene resin, Malin acid resin, pigments, fillers, dispersant, polyethylene wax, matte powder, adhesion promoter, the modifier of drying and volatile, ethyl acetate, ethanol, isopropyl alcohol. The preparation method sequentially consists of the following procedures: a) the dilution process; b) the initial dispersing process; c) grinding process; d) re-dispersing process. Compared with the prior art, the method has good adaptation of gravure plastic printing press, good solvent release, good printing adaptability and good adhesion fastness on the BOPP with the attachment is larger than or equal to 98 percent. The method can adapt to the printing speed of 300 m / min, and can meet the speed of the compound extrusion of 280 m / min. The peel strength after the extruding and composite of the printing film and PP particles is 1.5N / 15mm.

Description

technical field [0001] The invention relates to an extrusion composite ink and a preparation method thereof, in particular to a plastic printing composite ink extruded from PP particles which is suitable for gravure plastic printing and a preparation method thereof. Background technique [0002] Extrusion composite ink is to transfer the ink to the plastic film through the gravure printing machine, and then through the extrusion lamination machine at a high temperature of 300 ℃, the PE and PP particles are melted and salivated and the printing film ink side is pressed and bonded. Many printing and packaging enterprises adopt This kind of composite method is to reduce the production cost. Since the extrusion process is composited at a high temperature of 300 ° C, the ink needs to have high performance requirements for bonding with PE and PP materials at high temperatures to meet the composite strength requirements. At present, the printing ink used for extrusion compounding i...
