Problems solved by technology

And because radiation polymerization needs to be carried out under the condition of passing nitrogen deoxidation, and radiation source is expensive, so the production cost of this method is higher and the solid content of the prepared adhesive emulsion is lower (about 40%)

Abstract

The invention discloses environmentally-friendly acrylic ester coating printing adhesive emulsion and a preparation method. An emulsion polymerization process is adopted. The emulsion comprises the following raw materials in part by weight: 50 to 90 parts of soft monomer, 10 to 20 parts of hard monomer, 2 to 10 parts of functional monomer, 2 to 5 parts of emulsifying agent, 0.2 to 0.5 part of initiator, 0.2 to 0.5 part of pH buffer, 80 to 120 parts of deionized water and a proper amount of pH adjustor, wherein the total amount of the soft monomer, the hard monomer and the functional monomer is 100 parts by weight. The three monomers are cooperatively used as functional monomers for generating carboxyl crosslinking, hydroxy crosslinking, epoxy crosslinking and the like so that the obtained printing adhesive emulsion has excellent water tolerance and mechanical property. The crosslinking monomers and the emulsifying agent do not contain the components such as N-methylol acrylamide, APEO and the like, so the emulsion does not release formaldehyde during baking and using and is suitable for high-grade environmentally-friendly printing adhesive.

Description

technical field [0001] The invention relates to a printing adhesive and a preparation method thereof, in particular to an environment-friendly high-grade paint printing adhesive emulsion and a preparation method thereof. Background technique [0002] Pigment printing is a printing process in which the paint is adhered to the surface of the fiber by means of an adhesive to obtain the desired pattern. It has been widely used in various textiles. It has the advantages of simple process, bright color, clear pattern, energy saving and time saving, and less waste. . The color paste of pigment printing is mostly composed of pigments, binders, thickeners and other additives. Among them, the weight of the adhesive has the most critical influence on the hand feeling, vividness, and various fastness (friction, washing and dry cleaning fastness, etc.) of the printed product. [0003] Most of the printing adhesives currently on the market contain a certain amount of N-hydroxyacrylamide...
