Abstract

The invention discloses a thickening agent having the advantages of good water holding property, strong electrolyte resistance and high color yielding rate and a production process having the advantages of simple process, environmental protection and energy saving. The process with the following raw material components and weight ratios comprises the following steps of: neutralizing 200g of acrylic acid and 40g of methacrylic acid by using 350g of 32 percent sodium hydroxide to a pH value of 6.3-6.4; mixing 60g of acrylamide, 0.3g of N-N' methylene-bisacrylamide and 1.4g of potassium persulfate as an initiator into a water phase; adding 200g of white oil or aviation coal, 30g of sorbitan monooleate, 5g of butyl acrylate into a reactor and mixing to prepare into an oil phase; adding the water phase to the oil phase for emulsifying for 10 minutes and then adding 0.4g of sodium hydrosulfite to begin a polymerization reaction; heating up to 90 DEG C, preserving heat for 1 hour and then cooling to 40 DEG C; and adding 30g of fatty alcohol-polyoxyethylene ether and 20g of hydrophilic silicon oil to the reacted and cooled material and sufficiently mixing. The invention is suitable for thickening agents and production thereof.

Description

technical field [0001] The invention relates to a thickener for textile printing and a production process, in particular to an environment-friendly universal thickener for dispersion and active printing and a production process. Background technique [0002] Traditional thickeners consume a lot of energy in the production process, and produce AEOP at the same time, which has a negative impact on the environment. Moreover, the product is not resistant to electrolytes, the amount of use is large, and the cost of use is high. The printed textiles are dark in color and feel poor. . However, natural polymer pastes such as sodium alginate have long pulping cycles, and the prepared pulp is prone to mildew and other deficiencies. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a thickener with good water holding capacity, strong electrolyte resistance and high color yield and a production process with simple process, en...
