Problems solved by technology

[0003] The existing weak solvent products on the market are mainly weak solvent PP synthetic paper, weak solvent PVC film, weak solvent photo paper, weak solvent lamp film, and the coating formula mainly includes acrylic emulsion, matte powder, polyvinyl alcohol, whitening agent, Wetting agent and defoaming agent mainly emphasize the adjustment of color performance and drying speed after printing, and lack of formula to solve the static electricity problem in practical application. This kind of material can work normally when the humidity is greater than or equal to 50%. Use, but it will affect the use in autumn and winter when the humidity is lower than 50% or in the northern region. Serious static spots will be generated during printing, the picture will be blurred, the lines will be misaligned, and the static electricity will cause the material to adsorb and the printing plate will not run. easy to electric shock
Since the acrylic emulsion in the weak solvent coating is an anionic system, it is difficult to add a cationic antistatic agent with strong antistatic effect. The common method is to solve the static problem of weak solvent products by externally coating the antistatic agent, but the external coating antistatic agent requires additional Adding the coating and drying process not only increases the complexity of the operation, but also increases the manufacturing cost. At the same time, the cationic antistatic agent is slightly acidic, which easily leads to yellowing and fading of the coating

Abstract

A matt and antistatic spray coating, comprising, in parts by weight, raw materials of: 20-30 parts of pure acrylic emulsion, 15-25 parts of styrene-acrylic emulsion, 5-10 parts of polyvinyl alcohol glue, 3-8 parts of matt powder, 2-5 parts of antistatic agent solution, 1-3 parts of kaolin, 0.1-0.2 parts of dispersant, 0.2-0.5 parts of whitening agent, 0.2-0.5 parts of antifoaming agent, 0.5-0.8 parts of conductive agent, 0.4-0.6 parts of wetting agent and 30-40 parts of deionized water. A preparation method for said spray coating comprises steps of: formulating an antistatic agent solution, formulating polyvinyl alcohol glue, formulating spray coating, etc. Said spray coating has advantages such as wide range of use, antistatic properties, and soft and bright printing color.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a matte antistatic spray painting coating and a preparation method thereof. Background technique [0002] Inkjet printer ink types are mainly divided into water-based, weak solvent, solvent, and UV. The surface of water-based printing consumables is coated with water-based ink-absorbing coating. The coating is not water-resistant. After spraying the surface of the picture, it needs to be covered with cold lamination film. It is mainly used indoors. Solvent-based ink is mainly used on PVC car stickers and PVC light box cloth because of its strong corrosiveness, and the ink contains strong solvents, which are harmful to the human body. Strong solvent inkjet printing is gradually being replaced. UV-type ink has good adhesion and strong three-dimensional effect. It is mainly used for flat printing on glass sliding doors, ceramic tile inkjet printing, and plastic film materials. Compared wit...
