Problems solved by technology

However, the above processing mode and the ink used have disadvantages: 1) high-temperature sintered products require high temperature above 600 degrees, which consumes a lot of energy; 2) solvent-based products use volatile solvents, which pollute the environment; 3) The curing speed of water-based ink is slow, and it still needs curing conditions above 160 degrees. Generally, it needs to be stored for 1 week to achieve the maximum firmness; 4) The printing method is single, and only screen printing can be used, which cannot be used in some inks. Three-dimensional shape of glass bottles, glass balls and other products, so its application is strictly limited in many aspects

preparation example Construction

[0022] The preparation method of this solvent-free ultraviolet light curing glass ink of the present invention, the method comprises steps as follows:

[0023] (1) Ingredients: In a certain volume of agitable open tank, first add multifunctional polyester acrylate, a part of functional acrylate active monomer, initiator and co-initiator, inorganic pigment or organic pigment, and use Pre-disperse at medium speed (200rpm-500rpm) with disc-type stirring paddle for 30 minutes, and the temperature of the material is required to reach above 50°C;

[0024] (2) Rolling and dispersing to form the base ink: use one or a combination of bead mills and three-rollers, control the temperature of the rolling rolls at 50-55°C and pressure 40-50Bar by passing cooling water, and roll Twice, use a double-slot scraper (0-25μm) to test the dispersion, and the fineness is required to be below 10μm to be qualified.

[0025] (3) Tempering: Add defoamer and leveling agent to the dispersed base ink, an...

Abstract

The invention relates to a no-solvent ultraviolet curing glass printing ink and a preparation method thereof; the ink takes high-tractility photochemical active polyester acrylic ester as main ingredient, takes initiator and assistant initiator as curing agents and takes defoamer and flatting agents as auxiliary materials, and then inorganic or organic pigment is mixed, and a functional acrylic ester activated monomer is used as a viscosity regulator; the proportion of the ingredients of the no-solvent ultraviolet curing glass printing ink is as follows: 20-60 parts of multi-functional polyester acrylic ester, 3-8 parts of initiators, 2-5 parts of assistant initiator, 1-3 parts of defoamers, 0-1 part of flatting agent, 8-50 parts of inorganic pigments, 8-15 parts of organic pigments and 10-30 parts of functional acrylic ester activated monomers; the preparation method comprises batching, rolling dispersion and tempering steps; the no-solvent ultraviolet curing glass printing ink has the advantages that: 1. the ink is a 100-percent curing system, has no solvent volatilization and is harm to human body. 2. the curing performance is good, two mercury high pressure lamps with 80-120w / cm are adopted, and complete curing can be realized within 3-6 seconds. 3. the activated monomer is used to regulate the system viscosity, the ink is applied to pad transferring or silk-screen printing, and the universality is strong.

Description

technical field [0001] The invention relates to a carbon black dispersant and a preparation method thereof, mainly a solvent-free ultraviolet light curing glass ink and a preparation method thereof. Background technique [0002] For many years, graphic printing on the glass surface has mainly used screen printing to print high-temperature sintered inks and low-temperature cured solvent-based inks. In recent years, literature and patents have proposed water-based and environmentally friendly low-temperature curing glass inks. However, the above processing mode and the ink used have disadvantages: 1) high-temperature sintered products require high temperature above 600 degrees, which consumes a lot of energy; 2) solvent-based products use volatile solvents, which pollute the environment; 3) The curing speed of water-based ink is slow, and it still needs curing conditions above 160 degrees. Generally, it needs to be stored for 1 week to achieve the maximum firmness; 4) The pri...
