Abstract

The invention discloses an environment-friendly type adhesive for coating printing and dyeing as well as a preparation method and application thereof. The adhesive is prepared from the following components through reacting: a soft monomer, a hard monomer, a cross-linking monomer, a comonomer, an emulsifier, an initiator and a formaldehyde catching agent. A preparation process comprises the following steps: adding xanthan gum and 1 / 3 of soft water in sequence and stirring for dissolving; then adding selenious acid; dropwise adding 4-(2-ethylamino)benzene-1,2-diphenol; carrying out thermal insulation reaction; regulating the pH (Potential of Hydrogen) to be neutral; then adding 2 / 3 of soft water and 1 / 2 of the emulsifier and dissolving; then dropwise adding mixed liquid of the soft monomer,the hard monomer, the cross-linking monomer, 1 / 2 of the initiator and 1 / 2 of the emulsifier; carrying out thermal insulation reaction and rapidly raising the temperature; rapidly adding the comonomerand 1 / 2 of the initiator and stirring; then adding the formaldehyde catching agent; rapidly cooling and regulating the pH; cooling and carrying out thermal insulation reaction; naturally cooling, andfiltering and discharging to obtain the environment-friendly type adhesive. When the adhesive disclosed by the invention is used for carrying out coating printing, no formaldehyde is released and environmental protection is realized.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing adhesives, in particular to an environment-friendly adhesive for paint printing and dyeing, its preparation method and application. Background technique [0002] Pigment printing and dyeing (pigment printing and dyeing) has excellent characteristics such as simple process, less water consumption, and less pollution, and is suitable for printing and dyeing of various fibers. Therefore, the application prospect of pigment printing and dyeing in textile processing procedures is very broad. The structure and properties of the binder have a decisive influence on the quality of the pigment printing and dyeing products. [0003] At present, the main products of paint printing and dyeing adhesives are low-temperature self-crosslinking adhesives. This type of adhesive is easy to release free formaldehyde which is harmful to the human body during production, transportation and use, and p...
