Abstract
The invention relates to the technical field of paint, and discloses a glass roller coating adhesion primer solidified by a UV light source and a preparation method thereof, wherein the preparation raw materials comprise, by mass, 40-60 parts of acrylate prepolymer, 45-55 parts of acrylate monomer, 10-20 parts of adhesion promoter, 1-15 parts of coupling agent, 10-20 parts of filler, 0.1-5 parts of initiator, 0.1-5 parts of defoamer and 1-5 parts of dispersing agent. According to the invention, polyurethane acrylic ester and acrylic ester monomer are compounded, the monomer and the wetting dispersant are compounded, and then adhesive resin, phosphate, silane coupling agent and filler are matched to ensure the construction effect and improve the adhesive force, improve the delamination condition on a glass plate and improve the boiling resistance and the soaking resistance.
Description
Technical Field
The invention relates to the technical field of coatings, in particular to the field of IPC C09D167, and more particularly relates to a UV light source cured glass roller coating adhesion primer and a preparation method thereof.
Background
At present, paint for glass surfaces in the market mainly comprises water paint products which are directly sprayed, but the water paint spraying has certain defects, the paint film has long waiting time, the occupation space of plates is large, the paint consumption is large, and the mechanized high-efficiency production is difficult. The UV light curing roller coating primer can meet the requirement of batch high-efficiency mechanized production, can solve the problem of space occupation, has small paint consumption and greatly reduces the cost. In addition, the water-based paint sprayed on glass has poor boiling resistance, and the traditional UV roller coating adhesion primer is easy to delaminate on a glass plate, and has unsatisfactory boiling resistance and boiling resistance.
In order to solve the problems, application document CN201810901862.X discloses a toughened glass water-based UV primer, wherein the preparation raw materials comprise modified polyurethane acrylate, acrylic ester, hydroxy acrylic ester, defoamer, wetting agent, leveling agent, scratch-resistant agent and silicon dioxide. The yellowing resistance of the primer is improved by preparing the modified polyurethane acrylic ester with the shout conjugated benzene ring structure, and the primer has high flexibility and high strength, but no study on boiling resistance, water resistance and adhesive force is performed.
Application CN201711352415.5 discloses a UV primer for glass surfaces, the raw materials for preparation of which comprise epoxy acrylate, monomer, initiator, defoamer, leveling agent, wetting agent, dispersant and anti-settling agent. The epoxy acrylate with higher hydroxyl value and acid value is selected as a main body of the coating, so that good adhesive force of the coating on the surface of glass is ensured, and the adhesive force is further improved by selecting a low-functionality monomer.
Disclosure of Invention
In order to solve the problems, the invention ensures the construction effect and improves the adhesive force by compounding polyurethane acrylic ester, acrylic ester monomer and wetting dispersant and then matching adhesive resin, phosphate ester, silane coupling agent and filler, improves the situation that delamination occurs on a glass plate and improves the boiling resistance and the soaking resistance.
