The pigment printing is used crosslinking agent
Pigment printing is a method of printing on the fabric by using a polymer to form a thin film on the fabric.
Pigment printing paste by, thickener, coatings, adhesives and a small amount of auxiliary materials, made by adhesives coatings mechanical fixation on fiber surface, adhesive determines the printing soaping fastness and rubbing fastness of the fabric, so the performance of the adhesive in printing plays an important role. The structure of pigment printing adhesive is divided into three types: non-crosslinking, diplomatic and self-crosslinking.
Based on acrylic acid - 2 - ethyl acetate, butyl acrylate, methyl methacrylate and styrene as the main monomer, using emulsion polymerization preparation since the crosslinking pigment printing adhesive glue agent. By adjusting the type and proportion of acrylate copolymer, a kind of self-crosslinking pigment adhesives with good overall performance was obtained.
Experimental materials and equipment: - 2 - acrylic acid ethyl ester (2 - EHA), butyl acrylate (BA), methyl methacrylate (MMA), styrene (St) (pure chemicals); The above monomer is refined by decompression distillation. Np-10, LAS (chemically pure); Potassium sulfate (analytical purity); Deionized water; Reactive monomer M: self-control.
Instrument: Y571B friction fastness tester, swing-12a type fastness tester.

Risk Codes: R10; R35
RIDADR: UN 3082
Safety instructions: S2; S26; S39; S61
Packing Group: III
Hazard Class: 6.1
Equipped with electric mixer, reflux condenser pipe, thermometer and constant pressure drop funnel four flask, adding compound emulsifier, a moderate amount of deionized water and part of the monomer acrylic acid - 2 - ethyl ester, butyl acrylate, methyl methacrylate, styrene, reactive monomer M fully mix, pre emulsion.
To add a quarter of the initiator in the emulsion solution and heating to 80 ~ 80 ℃, for there was a blue emulsion, maintain 5 min after the start, add the rest of the monomer and initiator solution 3 h drop down, then up to 90 ℃ heat preservation 30 min, down to room temperature, adjust pH value of 7 ~ 8, was milky blue emulsion.
Printing: paint blue 4%, glue adhesive 20%, thickening agent 4%, deionized water to 100%. Drying (100 ℃, 3 min) - baking (140 ~ 150 ℃, 3 min) - post-processing.
Major performance testing. Appearance: visual measurement; PH: precision pH test paper; Viscosity: NDJS - 79 rotating viscosity meter; Condensation rate, solid content: weight method; Rubbing fastness: GB/t3920-1997. Colour fastness: press GB/T3921. 1-1997. Softness: a hand touching method.
The effect of soft, hard monomer ratio. Monomer is the foundation of the polymer, which has an important influence on the physical, chemical and mechanical properties of the polymer. - 2 - ethyl f acrylate, butyl acrylate, good film-forming, softness and washing fastness, the addition of methyl methacrylate, styrene can increase the toughness and abrasion resistance of adhesive film. This experiment selected soft monomer acrylic acid - 2 - ethyl acetate and butyl acrylate, hard monomer methyl methacrylate and styrene, self-made multifunctional monomer M as crosslinking monomer.
The ratio of soft/hard monomer is too large or too small, and the emulsion polymerization is unstable. With the increase of the ratio of soft/hard monomer, the printing products feel soft, the wet friction fastness increases, the dry friction fastness changes very little. Considering the stability of emulsion polymerization and the performance of printed products, the ratio of soft/hard monomer is 2. 0:1. The experiment also found that when 2 - EHA: BA: MMA: St = 24:40:20: the printing products made by the time of 11 are the best, the rubbing fastness is the best.
