The adhesive of the invention is an aqueous 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]
The present invention relates to a kind of environment-friendly type printing table adhesive agent emulsion and preparation method thereof, belong to the painting manufacture field.
[background technology]
Shortcomings such as the fifties rises, and at the traditional dyeing complex process, pollutes greatly, and cost height and price cycle are long, risen pigment printing abroad, the pigment printing operation is simple, the saving energy, non-wastewater discharge, and chromatogram is complete, the colorant match spline is convenient, the stamp clear-cut, and percentage of A-class goods height, circulation ratio is strong.China begins the research work of this respect subsequently since sixties import pigment printing acrylic adhesives.In the whole process of textiles processing, people pursue is that technology is simple, investment is low, equipment is few, economize the energy, require simultaneously not have or a small amount of discharging of waste liquid to protect environment.Pigment printing technology then can satisfy above-mentioned requirements fully.
In the process of textile printing, for guaranteeing carrying out smoothly and chromatography precision accurately of stamp, the normal way that applies layer of adhesive at printing table that adopts, with smooth the sticking on the printing table of the textile cloth of softness, its platen tackiness agent quality quality directly influences the chromatography of stamp cover to the accuracy of flower.If the platen tackiness agent can't its textile cloth of smooth adhesion, the fabric cloth ground that takes place when textile printing slides or peels off with platen, makes that the stamp chromatography is inaccurate, and the decalcomania lines are unintelligible, thereby influence the quality of decalcomania.Therefore, both require this tackiness agent to have good tack, and required tackiness agent that the stronger interior poly-viscous force of holding is arranged again, do not adhere to textile cloth when playing cloth, when the cloth hair sticks on the platen, do not fall glue after the platen washing simultaneously, platen glue of blade coating can be repeatedly used.Chinese invention patent application CN1563239A has reported a kind of water-soluble acrylic ester printing table glue and preparation method thereof and application, but add volatile matters such as ethanol, propylene glycol monomethyl ether or Virahol in its preparation process, use cross-linking monomer to be N hydroxymethyl acrylamide, when film forming is crosslinked, can slow release go out formaldehyde, environment there is pollution, this platen glue is the water-soluble acrylic ester class simultaneously, and water tolerance is relatively poor, can't repeatedly use by a blade coating.
[summary of the invention]
