A kind of glass high stability UV-curable water-borne ink
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of glass high stability UV-curable water-borne ink.
Background technology
In recent years, along with people are to the reinforcement gradually of the pay attention to day by day of environment protection and environmental regulation, various countries are more and more limited for the discharge of volatile organic matter contained in traditional solvent based coating.Therefore, the Main way that the low stain even water-borne coatings of nonpollution environment friendly, photo-cured coating have become coating manufacture is developed.
The water-borne coatings of ultraviolet light polymerization combines the advantage of water-based technology and UV-curing technology, have that curing speed is fast, environmental friendliness and the advantage such as energy-conservation, simultaneously, it also overcomes the shortcoming such as skin irritation that traditional UV-curing technology brings and the film performance difference that water-based technology is brought, be many traditional coatings incomparable.
Along with development in science and technology, the raising of people's standard of living, for the continuous lifting of target level of product quality, general coating on the market can not meet new standard new demand with rapid changepl. never-ending changes and improvements, is therefore badly in need of a kind of high performance ultraviolet-curing paint.
Summary of the invention
The present invention is directed to above-mentioned background technology, a kind of glass high stability UV-curable water-borne ink is provided.
For realizing the object of the invention, the technical solution used in the present invention is as follows:
A kind of glass high stability UV-curable water-borne ink, is characterized in that: count by weight, is prepared from by following raw material: acrylate modified polysiloxane pre polymers body: 50 ~ 60 parts; Pigment: 1 ~ 2 part; Photoepolymerizationinitiater initiater: 2 ~ 5 parts; Reactive thinner: 10 ~ 20 parts; Defoamer: 1 ~ 5 part; Aqueous solvent: 100 ~ 120 parts;
Described acrylate modified polysiloxane pre polymers body is prepared from by following steps: mixed with gamma-methyl allyl acyloxypropyl trimethoxysilane by two terminal hydroxyl dimethyl-polysiloxanes and add stirring, add dibutyl tin laurate again, be heated to 80 ~ 100 DEG C, continue 8 ~ 10h, purify and get final product.
Further, described a kind of glass high stability UV-curable water-borne ink is counted by weight, is prepared from: acrylate modified polysiloxane pre polymers body: 55 parts by following raw material; Pigment: 1 part; Photoepolymerizationinitiater initiater: 5 parts; Reactive thinner: 15 parts; Defoamer: 3 parts; Aqueous solvent: 100 parts.
Further, described reactive thinner is pentaerythritol triacrylate or dipentaerythritol five acrylate.
Further, described Photoepolymerizationinitiater initiater is benzoin methyl ether, Benzoin ethyl ether or said mixture.
Further, described defoamer is tributyl phosphate.
Further, described aqueous solvent is propyl alcohol and water mixture.
Present invention also offers a kind of making method of above-mentioned a kind of glass high stability UV-curable water-borne ink, comprise the following steps: by acrylate modified polysiloxane pre polymers body, pigment, reactive thinner, defoamer, aqueous solvent, abundant mixing is also heated to 30 ~ 50 DEG C of stirring 10 ~ 30min, add Photoepolymerizationinitiater initiater again, stir, then leave standstill cooling and get final product.
The invention provides a kind of glass high stability UV-curable water-borne ink, beneficial effect is as follows:
A kind of glass high stability UV-curable water-borne ink of the present invention, with two hydroxy-terminated polysiloxanes and gamma-methyl allyl acyloxypropyl trimethoxysilane for single main body prepares acrylate modified polysiloxane prepolymers, possesses good preservation stability, solidification rate, snappiness and hardness; Coordinate suitable Photoepolymerizationinitiater initiater, reactive thinner, defoamer etc. to make anti-stick coating, there is moderate application viscosity, good adhesive power and higher adhesion residual rate.Save energy of the present invention, environmental, Simplified flowsheet, improve the quality of products, there is vast potential for future development.
