Process for preparing modified acrylic emulsion capable of preventing dye from migrating and sublimating

Abstract

The invention relates to a process for preparing modified acrylic emulsion capable of preventing dye from migrating and sublimating. The process is characterized by comprising the steps of stirring and mixing fatty alcohol-polyoxyethylene ether as a emulsifier, sodium secondary alkyl sulfonate and soft water at a weight ratio of (1-3): (1-3): (14-18) at 15-35 DEG C in an emulsifying tank for 3-4 minutes under normal temperature and normal pressure, preparing into an initial pre-emulsion solution, and then preparing into primary monomer pre-emulsion containing butyl acrylate, acrylonitrile and isooctyl acrylate, thus obtaining stable reaction pre-emulsion and finally obtaining modified acrylic emulsion capable of preventing dye from migrating and sublimating. The coating adhesive prepared from acrylic emulsion capable of preventing dye from migrating and sublimating can effectively prevent an easily sublimable fabric from sublimating after the fabric is gelatinized. Therefore, the inventor proposes a better technology to obtain the final product having better quality and the product is suitable for being used as printing rubber cement in the textile pigment printing process.

Description

technical field

[0001] The invention relates to a preparation process of a modified emulsion, in particular to a preparation process of an acrylic acid modified emulsion for preventing dye migration and sublimation. 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 mucilage, acrylate emulsion or polyurethane emulsion, are generally used as film-forming materials, and v...
