Printing method of printing ink with high adhesive force

Abstract

The invention discloses a printing method of printing ink with high adhesive force. The printing ink is prepared from the following raw materials in parts by weight: 30 to 50 parts of organic pigment,40 to 60 parts of solvent, 3 to 5 parts of barium sulfate, 4 to 6 parts of low-polymerization linseed oil, 15 to 25 parts of modified alkyd resin, 15 to 25 parts of rosin modified phenolic resin, 1 to 3 parts of preservative and 0.3 to 0.5 part of butyraldoxime. Compared with other treatment processes, rosin modified phenolic resin and modified alkyd resin are mixed for use to replace traditionalsingle resin such as petroleum resin and epoxy resin; the mixed resin has good emulsion resistance; good stability and fixation performance are realized; good wetting performance is realized on pigments and printed materials; according to the printing ink, the UV light source is used for emitting UV light, so that the adhesive force of the printing ink is improved, fading and falling are not likely to happen, the environment temperature is controlled below 30 DEG C in the using process, the power of a UV lamp is reduced, the drying time is prolonged, and the situations that longitudinal overprinting precision is affected and adhesiveness is reduced due to too fast printing ink drying are avoided.

Description

technical field [0001] The invention relates to a printing ink production process, and more specifically relates to a printing method of printing ink with strong adhesion. Background technique [0002] Printing is to transfer the ink to the surface of paper, fabric, plastic, leather and other materials through plate making, ink application, pressure and other processes to copy the content of the original manuscript in batches. The approved printing plate is transferred to the substrate through printing machinery and special ink. Ink is usually used as the main printing material. The ink expresses the pattern and text on the substrate through printing or spray painting. The ink includes the main components and Auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid, composed of binder resin, pigment, filler, additives and solvents, used for books, packaging and decoration, architectural decoration and electronic circuit boards ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a printing method of printing ink with strong adhesion, mature technology, rosin modified phenolic resin has good gloss, good water resistance and adaptability to ink configuration Good characteristics, mixed with modified alkyd resin to replace single resin such as petroleum resin and epoxy resin commonly used in traditional inks, modified alkyd resin and rosin-modified phenolic resin have good emulsification resistance after mixing, and have good Excellent stability and fixation, good wetting performance for pigments and substrates, thereby improving the adhesion of the ink, not easy to fade and fall off, and the ambient temperature is controlled below 30°C during use, Reduce the power of the UV lamp to prolong the drying time, avoid affecting the accuracy of longitudinal overprinting and reduce the adhesion of the ink due to too fast drying. Preservatives are added during the ink production process. The material is MD-149 ink bactericidal preservative, which is an efficient Industrial fungicide, broad-spectrum bactericidal, can effectively kill and inhibit bacteria, including Gram and Gram-negative bacteria, mold, yeast and other microorganisms, can quickly and long-term kill various microorganisms, good anti-corrosion safety , has special effects on Pseudomonas aeruginosa, bacteria, fungi, mold and algae that are difficult to control in the industrial product system, improves the problem of bacteria breeding and corruption during ink transportation and storage, prolongs the service life of ink, and adds butyraldehyde during ink manufacturing As an anti-skinning agent, oxime forms a complex with a drier, temporarily deactivates the drier, avoids skinning, reduces ink waste, and avoids yellowing of the ink film. Due to the small dosage, Therefore, it has little effect on the drying rate of the ink
