Textile printing thickening agent and production process thereof

Abstract

The invention discloses a textile printing thickening agent. The textile printing thickening agent is prepared by processing the following raw materials in parts by weight: 150-220 parts of acrylic acid, 20-60 parts of methacrylic acid, 50-80 parts of acrylamide, 1-10 parts of octadecyl acrylate, 0.01-0.5 part of N,N'-methylene-bisacrylamide, 120-250 parts of white oil or aviation kerosene, 15-50 parts of sorbitan monooleate, 0.2-2 parts of an initiator, 0.01-1 part of sodium hydrogensulfite, 10-50 parts of fatty alcohol polyoxyethylene ether, 5-50 parts of hydrophilic silicon oil and 200-500 parts of a sodium hydroxide solution. The thickening agent has good water holding performance, strong electrolyte resistance capability and high color yield. A production process comprises the following steps of: (1) neutralizing the acrylic acid and the methacrylic acid until the pH value is 5.2-6.5; (2) adding the acrylamide, the N,N'-methylene-bisacrylamide and the initiator to prepare a water phase; (3) mixing the white oil or the aviation kerosene, the sorbitan monooleate and the octadecyl acrylate to form an oil phase; and (4) adding the water phase into the oil phase and emulsifying, and adding sodium hydrogensulfite to carry out a polymerization reaction; and (5) adding the fatty alcohol polyoxyethylene ether and the hydrophilic silicon oil and mixing.

Description

Technical field [0001] The invention relates to a textile printing thickener and its production process. Background technique [0002] Traditional thickeners consume a lot of energy during the production process, and at the same time produce APEO, which has a negative impact on the environment, and the product is not resistant to electrolytes, the usage is large, the use cost is high, the printed textiles are dark in color and have poor hand feeling . However, natural polymer pastes such as sodium alginate have disadvantages such as long pulping cycle and easy mildew of the prepared pulp. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a textile printing thickener with good water holding capacity, strong electrolyte resistance and high color yield. [0004] The textile printing thickener provided by the present invention is prepared by processing the following raw materials in parts by weight: [0005] Acrylic 150-220 pa...

AI Technical Summary

Problems solved by technology

[0002] Traditional thickeners consume a lot of energy in the production process, and produce APEO at the same time, which has a negative impact on the environment. Moreover, the products are not resistant to electrolytes, use a large amount, 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 the disadvantages of long pulping cycle and easy mildew of the prepared pulp.
