Abstract

The invention discloses a high Dyne value and ultraviolet resistance screen printing ink for glass panels and a preparation method thereof. The printing ink mainly comprises raw materials in parts byweight: epoxy resin 20-70 parts, mica 3-4 parts, wollastonite 7-8 parts, 783 slow dry water 1-3 parts, adhesion promoter 2-4 parts, Y-Butylactone 22-25 parts, turpentine 25-34 parts, dispersant 3-4 parts, defoamer 4-5 parts, silica 2.5-6 parts, black pigment 4-20 parts, ultraviolet absorber 0.5-2 parts, and bis-sebacate 1-5 parts. The raw materials are put into homogenization equipment, grinding machine and three-roller machine in different sequences to finally obtain printing ink with required fineness. After the invention is applied, the adhesion force, dyne value and ultraviolet light resistance of the printing ink can be improved, thus improving the printing stability of the printing ink.

Description

technical field [0001] The invention relates to a glass screen printing ink, which belongs to the field of glass panel manufacturing. Background technique [0002] Printing is a technology that transfers the ink to the surface of glass, paper, textiles, plastics, leather and other materials through the processes of plate making, ink application, and pressure to copy the contents of the original manuscripts in batches. The oil for screen printing is ink, which is an important material for screen printing. Patterns and characters are reflected on the substrate by printing or inkjet painting. The ink includes main components and auxiliary components, which are uniformly mixed and repeatedly ground to form a viscous colloidal fluid. It is composed of resins, pigments, filler additives and organic solvents. It is used for various printing on glass panels, books and periodicals, including decoration, architectural decoration and electronic circuit boards. With the increase of s...
