Problems solved by technology

Chinese invention patent application CN1563239A has reported a kind of water-soluble acrylic printing table glue and its preparation method and application, but in its preparation process, add volatiles such as ethanol, propylene glycol methyl ether or isopropanol, use crosslinking monomer as N -Hydroxymethylacrylamide, formaldehyde will be slowly released during film formation and cross-linking, which will pollute the environment. At the same time, the platen glue is water-soluble acrylic ester, which has poor water resistance and cannot be used for multiple times by scraping at one time

Abstract

The invention discloses an environment-friendly printing platen adhesive emulsion and a preparation method thereof, and the emulsion comprises the following components by weight: 25%-45% of soft monomers, 4%-10% of hard monomers, 1%-6% of functional monomers, 0.1%-0.3% of initiators, 1%-6% of emulsifiers, 45%-65% of deionized water, and 0.5%-5% of neutralizers. The adhesive of the invention is anaqueous environment-friendly product, adopts water as a solvent, does not contain any volatile solvent, is environment-friendly, does not discharge toxic substances such as formaldehyde and the like,does not contain alkylphenol additives; the adhesive has good adhesive force to various textile fabrics; fabrics are not easy to slide on the platen or be separated from the platen; printing color register is accurate; the preparation method of the invention adopts a new crosslinking monomer, and increases the water resistance and cohesive adhesion lasting force of the adhesive; the adhesive can be used repeatedly; because of the good cohesive adhesion lasting force of the adhesive, no adhesive is left at the fabric bottom during fabric removal; meanwhile the adhesive of the invention has moderate and adjustable viscosity, is convenient for using, and is easy to adhesive application by a scraper plate.

Description

【Technical field】 [0001] The invention relates to an environment-friendly printing platen adhesive emulsion and a preparation method thereof, belonging to the field of paint chemical manufacturing industry. 【Background technique】 [0002] Since the 1950s, in response to the shortcomings of traditional dyeing processes such as complex dyeing process, high pollution, high cost and long price cycle, pigment printing has emerged abroad. The process of pigment printing is simple, energy-saving, no waste water discharge, complete color spectrum, and convenient color matching and imitation. The printing outline is clear, the authenticity rate is high, and the reproducibility is strong. my country only began to import acrylic adhesives for pigment printing in the 1960s, and then began research work in this area. In the whole process of textile processing, people pursue simple process, low investment, less equipment, energy saving, and at the same time require no or a small amount o...
