A kind of environment-friendly water-based printing acrylic emulsion and its preparation method and water-based printing paint

Abstract

The invention discloses an environment-friendly water-based printing acrylic emulsion, a preparation method thereof and a water-based printing paint. The emulsion includes 54-70 parts of butyl acrylate, 12-20 parts of styrene, 32-50 parts of ethyl acrylate, and 0.8 parts of acrylic acid. ~2 parts, acrylonitrile 5~10 parts, self-crosslinking monomer 0.6~1.2 parts, silicon functional monomer 0.3~0.8 parts, internal crosslinking monomer 3.4~6.0 parts, emulsifier 3~7 parts, initiator 0.4 ~1 part, 90~110 parts of deionized water; the emulsion is self-crosslinked quickly at low temperature, soft to the touch, excellent in elasticity, and excellent in anti-adhesion. The fabric has a special anti-dye color migration and sublimation effect; the method has stable reaction, strong controllability, environmental protection and energy saving.

Description

An environmentally friendly water-based printing acrylic emulsion and its preparation method and water-based printing coating technical field The present invention relates to textile printing paint and preparation field thereof, particularly a kind of environment-friendly water-based printing acrylic acid Emulsion and its preparation method and water-based printing paint. Background technique Along with the rapid development of my country's economy, people's living standards are improved qualitatively, and people's requirements for wearing are also From the single style of the past, it has become more and more particular about the aesthetics, comfort and washability of the printed patterns worn. The requirements for performance, durability and antifouling are also getting higher and higher. But the acrylic acid ester printing emulsion synthesized on the market at present is in order to pursue the softness of the hand feeling of the printing paint layer, generally ...

Problems solved by technology

At present, the crosslinking monomers containing N-methylolacrylamide, acrylamide and hydroxyalkyl acrylate are commonly used in the market, but they must be crosslinked during high temperature baking to improve the application performance of the emulsion, and the low temperature crosslinking speed Slow and insufficient strength, and N-methylolacrylamide is generally obtained from the reaction of acrylamide and excess formaldehyde solution, and the reaction is a reversible reaction, which will release free formaldehyde harmful to the human body and the environment during the crosslinking process, and with the With the enhancement of people's awareness of environmental protection and the promulgation of various national environmental protection policies and regulations in recent years, printing emulsions that are not environmentally friendly have been eliminated by the market.

In addition, it is also possible to increase the degree of cross-linking and application performance by adding an external cross-linking agent during silk screen printing. However, the addition of an external cross-linking agent has the problem of short timeliness for the use of slurry, which is likely to cause waste of glue
