Synthesis of low temperature formaldehyde free pigment printing adhesive

pigment dyeing and printing have the advantages of simple process equipment, energy saving and no waste water, and belong to environment-friendly products. Cha Gan, director of the general office of the president's office of Mongolia, said that it has been introduced into the development of attention, and the performance of the adhesive is the decisive factor that determines the final quality of pigment dyeing and printing. "At present, to improve the application performance of pigment printing adhesive, conference content:, In particular,

is the dry and wet rubbing fastness. The common method is to introduce the cross-linked monomer N-hydroxymethylacrylamide to participate in the copolymerization reaction in the synthesis process of the adhesive, but it needs high temperature baking, and it is easy to release free formaldehyde harmful to the environment and human body from the oil spill and other outlets. Some studies, such as pneumatic fixtures, have also studied the synthesis of formaldehyde free printing adhesives by introducing epoxy groups into epichlorohydrin to replace the crosslinking monomer N-hydroxymethylacrylamide, but the introduction of epoxy groups often brings Absorbable Organic Chlorine that is equally harmful to the environment. Therefore, low temperature formaldehyde free adhesive is our research direction

the purpose of this experiment is to develop a low-temperature formaldehyde free adhesive, so that the baking temperature can be reduced to 100cc or even lower, and the printing slurry is not blocked, the adhesive remains non sticky at high temperature, and the low temperature is not hard. The dry and wet rubbing fastness of the printed fabric meets the national standard, with soft hand feeling and large color giving, which meets the requirements of pigment printing, so as to save energy and reduce costs, So that pigment printing has a wider application. Therefore, we take acrylate as the basic raw material, and use the core-shell lotion polymerization method with soft component as the core and hard component as the shell to explore the synthesis of a low-temperature formaldehyde free adhesive, and apply it to pigment printing, and strive to solve the problems of its fastness and hand feel after use from the aspect of technology
