High-brilliance printing adhesive and preparation method thereof

Abstract

The invention discloses a high-brilliance printing adhesive and a preparation method thereof. The high-brilliance printing adhesive is prepared from the following materials in parts by weight: 30-50 parts of butyl acrylate, 15-25 parts of methyl methacrylate, 10-15 parts of acrylic acid, 2-3 parts of diacetone acrylamide, 1.5-2.5 parts of glycidyl methacrylate, 10-15 parts of amino silicon oil, 3-6 parts of maleic anhydride, 18-24 parts of sodium hydroxide, 5-10 parts of methacryloxy propyl trimethoxyl silane, 4-8 parts of vinyl trimethoxy silane, 2-3 parts of sodium dodecyl benzene sulfonate, 1-2 parts of an emulsifying agent AFX1080, 0.5-1 part of an emulsifying agent EF-810, 0.05-1 part of tert-dodecyl alcohol, 1-2 parts of sodium alcohol ether sulphate, 3-6 parts of modified attapulgite and 50-70 parts of water. When being used for printing fabric, the high-brilliance printing adhesive disclosed by the invention is good in handfeel, soft, high in elasticity and high in brilliance, also has excellent leveling performance, film forming performance, breathability and water resistance and the like, is low in harmful substance (formaldehyde) emission and meets the environment-protection requirement.

Description

technical field [0001] The invention relates to an adhesive, in particular to a high vividness printing adhesive and a preparation method thereof. Background technique [0002] At present, the existing printing adhesive synthesis technology adopts two methods of initiating polymerization, one is to use a chemical initiator and heat to initiate the polymerization reaction (chemical method for short), and the other is to use cobalt-60 gamma rays to irradiate the reaction at room temperature system to initiate polymerization (abbreviated as radiation method). Adhesives prepared by chemical methods have poor rubbing fastness, poor washing fastness, poor stability, and large fuzz in the printing and dyeing industry, and the resulting printed cloth surface is darker in color, and the color is old and not bright after being placed for a period of time; Because of the strong penetrating power of γ-rays in the radiation method, the particle size is relatively uniform and stable duri...

AI Technical Summary

Problems solved by technology

Adhesives prepared by chemical methods have poor rubbing fastness, poor washing fastness, poor stability, and large fuzz in the printing and dyeing industry, and the resulting printed cloth surface is darker in color, and the color is old and not bright after being placed for a period of time; Because of the strong penetrating power of γ-rays in the radiation method, the particle size is relatively uniform and stable during the reaction, and the products produced are also relatively stable. At the same time, the emulsion produced has high molecular weight, good chemical and mechanical stability, and high yield. The temperature is low, the production environment is good and there is no pollutant emission, etc., but the obtained printing adhesive also has a darker color on the printed cloth surface, and the level dyeing of the cloth surface cannot meet the needs of some high-end printing industry companies.
