Abstract

The invention relates to a preparation process of an acrylate resin emulsion having better abrasion-resistant performance. The preparation process is characterized by including the following steps that emulsifier fatty alcohol-polyoxyethylene ether, sodium alkylbenzene sulfonate and soft water are stirred and mixed in an emulsifying tank according to different weight ratios at the temperature of 15-35 DEG C under normal temperature and pressure for 10-30 minutes to obtain initial pre-emulsified liquid A1 and initial pre-emulsified liquid B1; main monomer pre-emulsified liquid A2 and main monomer pre-emulsified liquid B2 containing butyl acrylate, acrylonitrile and 2-ethylhexyl acrylate are prepared; then stable reaction pre-emulsified liquid A3 and stable reaction pre-emulsified liquid B3 are prepared; finally the acrylate resin emulsion having the better abrasion-resistant performance is prepared. The coating adhesive blended by adopting the acrylate resin emulsion can effectively solve the problem of poor color crockfastness of coating patterns. Therefore, the invention provides a better-quality final product obtained by adopting a better technological process. The product is suitable for printing of various manual platens and printing usage of round screens and flat screen printing machines.

Description

technical field [0001] The invention relates to a process for preparing an acrylate resin emulsion with good wear resistance and a process for preparing compound printing glue by using the acrylate resin emulsion with good wear resistance, belonging to the technical field of printing and dyeing. Background technique [0002] Acrylic resin paint is a synthetic resin paint with acrylate resin as the main film-forming substance. This kind of coating not only has the characteristics of light color, high transparency, full brightness, weather resistance, color retention, gloss retention, strong adhesion, corrosion resistance, hardness, flexibility, etc. Change the spelling resin to formulate a range of acrylic paints. [0003] In the printing process of textile pigment printing, it is necessary to print glue or color paste on the textile fabric through screen printing to form text patterns of various colors. At present, in pigment printing, two kinds of glue, acrylate emulsion ...
