Problems solved by technology

Acrylic glue has strong adhesive force, good fastness, and is widely used, but it tends to become brittle at low temperature and sticky at high temperature, and the hand feeling is not lively enough, and the poor elasticity of the film affects its use effect
Polyurethane glue has good elasticity and excellent hand feeling, but its high price limits its wide use
[0004] At present, for the physical blending system obtained by directly mixing polyurethanes and acrylates, there are often problems such as poor compatibility of the two components and poor transparency after film formation of the emulsion, which makes it difficult to achieve people's high-quality glue printing. need

Abstract

The invention discloses a preparation method and application of water-based acrylate glue. Aqueous acrylate glue is composed of isomeric tridecyl alcohol polyoxyethylene (40) ether, dioctyl sodium sulfosuccinate, itaconic acid, acetoacetoxyethyl methacrylate, hydroxyethyl methacrylate , ethyl acrylate, methyl methacrylate, styrene, isocyanate ethyl acrylate, acrylic modified reactive slip agent, ammonium persulfate, reducing agent FF6M, tert-butyl hydroperoxide, deionized water, first seed After emulsion polymerization, a polymerized emulsion is formed; an appropriate amount of deionized water is added to the polymerized emulsion to adjust the solid content to 45±1%; finally, the polymerized emulsion is prepared from thickener FS‑200E, glycerin, defoamer and the adjusted solid content income. The glue obtained by the invention has a soft and lively hand, is dry, has good elasticity and resilience, good weather resistance, no yellowing, no cracking, and excellent fastness. Application in screen printing paste.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a preparation method of water-based acrylate glue, and the application of the water-based acrylate glue in preparing glue for manual platen printing, rotary screen printing and flat screen printing. Background technique [0002] With the development of society, more and more attention has been paid to environmental protection. In the textile paint printing process, it is necessary to print the glue on the textile fabric through the screen to form text patterns of various colors. Screen printing is a production process that replaces dyes on fabrics. Since there is no waste water produced by rinsing during dye printing, it is a clean production process encouraged by the state. As a form of screen printing, glue printing can print any light color on dark clothes because of its very good pattern coverage, and it has a certain gloss and three-dimensional effect, making the...
