Environment-friendly printing adhesive

Abstract

An environment-friendly printing adhesive is characterized in that the printing adhesive is prepared from, by weight, 20-25 parts of self-crosslinking monomers 807-3, 10-12 parts of butyl acrylate, 20-25 parts of methyl methacrylate, 10-12 parts of acrylonitrile, 20-25 parts of acrylic acid, 15-20 parts of acrylamide, 1-5 parts of inorganic auxiliaries and 50-100 parts of deionized water. Cross-linking monomers N-hydroxymethyl acrylamide are not introduced for participating in a copolymerization reaction, the self-crosslinking monomers 807-3 are selected and used for replacing N-hydroxymethyl acrylamide, acrylic ester materials serve as basic raw materials, and the environment-friendly printing adhesive is synthesized by means of a pre-emulsification semi-continuous emulsion polymerization method. By means of the formula, the content of formaldehyde in the adhesive is effectively reduced, and the material is environmentally friendly and reliable.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an environmentally friendly printing adhesive. Background technique [0002] In the past ten years, the environmental protection problem in the process of adhesive synthesis and use has been a problem to be solved in the pigment printing industry. The standard of the International Textile Ecological Research Association stipulates that the formaldehyde emission of decorative cloth is less than 300×10 -6 , while the formaldehyde emission of baby clothing is lower than 20×10 -6 . 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 requires high temperature baking, and it is easy to release free formaldehyde which is harmful to the en...
