Abstract

The invention provides polyoxyethylene ether betaine polycarboxylate sodium salt and a preparation method thereof. The polyoxyethylene ether betaine polycarboxylate comprises 60-75 parts of fatty amine polyoxyethylene ether, 25-30 parts of carboxylic acid reagent, 20-25 parts of quaternizing reagent, 40-50 parts of solvent, 12-18 parts of alkali agent, 0.5-2 parts of pH adjuster, and 0.1-0.5 partof phase transfer catalyst. The invention relates to the polyoxyethylene ether betaine polycarboxylate sodium salt, and the polyoxyethylene ether betaine polycarboxylate sodium salt contains a betainezwitterionic surfactant which has no irritation to a human body and is green, environmentally friendly and biodegradable, so that environmental protection throughout the process from raw material production, finished product use and final emission is achieved.

Description

technical field [0001] The invention relates to an anti-staining soaping agent used in textile dyeing and finishing industry, which is used in textile printing and dyeing or printing. Background technique [0002] It is known that the printing and dyeing industry is an important component of the textile industry, and it is also an industry with high energy consumption and large sewage discharge. With the continuous development of society, environmental issues are getting more and more attention from the society, and the corresponding calls for environmental protection are getting higher and higher. Therefore, the official requirements for energy conservation, environmental protection and emission reduction of enterprises are also getting higher and higher. [0003] For the printing and dyeing industry, in addition to research and development of high-efficiency, water-saving, and energy-saving equipment, and the development and promotion of practical new technologies for ener...
