Non-aldehyde low-temperature adhesive

Abstract

The invention relates to an aldehyde-free low-temperature adhesive and belongs to the technical field of textile printing. The aldehyde-free low-temperature adhesive is characterized in that the adhesive is prepared from raw materials in weight portion: 65 to 75 portions of deionized water, 0.2 to 0.3 portion of fatty alcohol polyethenoxy ether ammonium sulfate salt, 0.8 to 0.9 portion of fatty alcohol polyethenoxy ether, 0.4 to 0.6 portion of methylene-succinic acid, 1 to 2 portions of glycidyl methacrylate, 15 to 18 portions of acrylic ester, 3 to 5 portions of styrene, 5 to 6 portions of acrylate and 0.02 portion of ammonium peroxydisulfate. A product is suitable for printing and coloring pure cotton, polyester cotton and other knitting fabrics and belongs to anionic / nonionic acrylate self-crosslinking latex. The aldehyde-free low-temperature adhesive has the characteristics that the adhesive can self crosslink at low temperature, need no high-temperature roasting and can reach properties of high fastness, high dry resistance and wet rubbing; and the aldehyde-free low-temperature adhesive has the highest level of environmental protection and does not contain APEO, phthalate and other prohibited chemicals.

Description

technical field [0001] The invention belongs to the technical field of fabric printing and dyeing, and in particular relates to an aldehyde-free low-temperature adhesive and its synthesis. The adhesive belongs to anionic / nonionic acrylate crosslinked emulsion. Background technique [0002] Pigment printing technology is a new technology developed by modern fabric printing and dyeing. It has the characteristics of simple process, saving money and energy, excellent quality of printed and dyed fabrics, reducing environmental pollution, and wide application. Therefore, it has been widely used. The pigment printing adhesive is the main component of the printing agent. Using the film-forming properties of the adhesive, various printing dyes can be attached to the fabric fibers to achieve the purpose of color printing. With the development of printing and dyeing technology and the improvement of the quality requirements of dyeing and weaving, pigment printing adhesives are also be...

Problems solved by technology

In order to improve the application performance of pigment printing adhesives in China, especially the dry and wet rubbing fastness, the commonly used method is to introduce cross-linking monomer N-methylolacrylamide to participate in the copolymerization reaction during the synthesis of the adhesive, but It needs high temperature baking, and it is easy to release free formaldehyde which is harmful to the environment and human body

There are also studies that introduce epoxy groups through epichlorohydrin to replace the cross-linking monomer N-methylolacrylamide to synthesize formaldehyde-free printing adhesives, but the introduction of epoxy groups often brings environmental pollution. Absorbable Organochlorine
