Machine printing binder for printing textiles and preparation method thereof

Abstract

The invention relates to a machine printing binder for printing textiles. The machine printing binder for printing textiles is characterized by comprising the following constituents according to part by weight: 70-100 parts of waterborne acrylic emulsion, 20-40 parts of waterborne polyurethane resin, 20 parts of glycerol, 10-20 parts of deionized water, 1 part of defoamer, 2-4 parts of abherent, 2 parts of antiblocking feel auxiliary, 6 parts of waterborne emulsion wax, 0.6 parts of multifunctional regulator, 1.6 parts of emulsifying thickener, 1.4-3.5 parts of waterborne thickener and 10 parts of ultrafine silicon dioxide. Sizes of the machine printing binder for printing textiles are printed on a screen printing machine continuously for 4-8 hours without blocking meshes; and printing products are placed for 24 hours at minus 20 DEG C, are good in feel and elasticity, and do not crack in stretching or fall off.

Description

Technical field: [0001] The invention relates to a machine printing glue, especially a machine printing glue for textile printing. Background technique: [0002] The mucilage products used for textile printing on the market today are roughly composed of water-based acrylic emulsion and various functional additives and pigments and fillers dispersed and emulsified according to a certain ratio. Due to the different levels of technical requirements and different production processes, the quality of many printing glues on the market is uneven, and the product stability is not good. It is easy to cause the following problems in the printing factory during use and in the printed products. : 1) The printing paste is sticky after printing and drying; 2) The net is blocked in the printing of flat screen fabric; 3) The sharp corners of the pattern become rounded, and the small dots are lost; 4) The printed matter appears sticky during transportation; 5) Printed products have poor wea...

AI Technical Summary

Problems solved by technology

Due to the different levels of technical requirements and different production processes, the quality of many printing glues on the market is uneven, and the product stability is not good. It is easy to cause the following problems in the printing factory during use and in the printed products. : 1) The printing paste is sticky after printing and drying; 2) The net is blocked in the printing of flat screen fabric; 3) The sharp corners of the pattern become rounded, and the small dots are lost; 4) The printed matter appears sticky during transportation; 5) Printed products have poor weather resistance, are not resistant to water washing, are easy to fall off, and are easy to crack and break in low temperature environments; 6) Printed products do not feel good, are too hard, and have poor elasticity

[0004] Due to the performance of the acrylic emulsion used in the printing paste itself, most of the printing pastes on the market have good performance at room temperature; but when the temperature is lower than zero degrees Celsius or lower, the printed matter is easy to burst , cracked, and various physical properties are greatly reduced

It is easy to stick back when the temperature is higher than 40 degrees, which makes the application range of this kind of slurry very limited, and also brings technical difficulties to many manufacturers in the industry

[0005] Adding high-boiling silicone oil as an antifreeze can make the slurry barely maintain the physical properties of the printed matter in a low temperature environment. Most of the antifreeze glue on the market is also solved in this way, but this method cannot solve the fundamental problem
