Abstract
The invention relates to a composite ink vehicle, particularly a composite ink vehicle for intaglio printing. The composite ink vehicle disclosed herein is prepared by firstly preparing a polyurethane prepolymer with double bonds, and then carrying out free radical polymerization on acrylic ester, methacrylate, vinyl acetate and the polyurethane prepolymer with double bonds at one end. According to the invention, only one end of the the polyurethane prepolymer with double bonds at one end participates in the free radical polymerization, thus the proportion of each raw material can be changed arbitrarily in the preparation of the ink vehicle, simultaneously gelation caused by a network structure produced by the reaction can be avoided; by introducing the polyurethane branched chain into the polyacrylate molecular main chain, the molecular polarity of the composite ink vehicle is effectively adjusted, thus the composite ink vehicle has good adhesive force to various plastic film substrates, can be used with alcohol soluble laminating adhesives and ester soluble laminating adhesives, and can satisfy the preparation requirements of the composite ink for intaglio printing.
Description
Technical field
The present invention relates to the compound oil ink binder, particularly a kind of compound oil ink binder for intaglio printing.
Background technology
In recent years, the raising of living standards of the people has driven the rapid growth of packaging industry, has also promoted to be used for the compound oil ink technology of intaglio printing and the development in market.The compound oil ink that is used at present intaglio printing has obtained to use very widely in plastic wrapping, and such as the packing of all types of plastic film substrate of the industries such as food, medicine, agricultural byproducts, daily necessities, its range of application has almost been included all packaging fields.
Because the compound oil ink of preparation mainly is adapted at printing on the BOPP film substrate take polyacrylic ester as ink adhesive, the compound oil ink of preparation mainly is adapted at printing on the PET film substrate take urethane as ink adhesive.For developing a kind of universal ink adhesive, numerous enterprises and scientific research institutions have actively launched the research work of related fields.Patent CN200910059587.2 discloses the preparation method that a kind of single liquid plastic gravure alcohol-soluble and water-soluble composite ink is used resin binder.The method makes ink adhesive by the urethane of hydroxy acrylate end-blocking and the polyreaction of acrylic ester monomer.But in the method because the large monomer of urethane two ends all participate in reaction, make in the ink adhesive of preparation or polyurethane content is difficult to improve, or gel reaction very easily occurs in the preparation process.
