Abstract

The invention provides a pigment printing binding agent and a synthesizing method thereof. The binding agent is prepared from silicone-acrylate copolymer, aqueous polyurethane, liquid rubber, an emulsifying agent and the like. By taking advantage of the high film-forming property of polyacrylic acid, the high flexibility of organic silicone, the high air permeability of polyurethane and the high elasticity of the liquid rubber, the high-fastness and super-soft pigment printing binding agent is prepared by a complex synergistic technology. The binding agent has high film-forming property, air permeability, flexibility and elasticity, good handfeel and high color fastness. After the binding agent is applied to a printing fabric, the release amount of a harmful substance, namely formaldehyde, is small.

Description

technical field [0001] The invention belongs to the technical field of chemical and chemical synthesis, in particular to the technical field of polymer synthesis and processing, in particular to a method for synthesizing an ultra-soft paint printing adhesive. Background technique [0002] Water-based pigment printing / pigment dyeing technology is an environmentally friendly printing and dyeing technology that conforms to the sustainable development strategy and is the development direction of the world's printing and dyeing technology.
