Problems solved by technology

[0005] Most of the purification links in the existing dimethyl hydroxy silicone oil production process mostly use simple filtration or activated carbon adsorption, and dimethyl hydroxy silicone oil used for fabric synthesis is not the same as dimethyl hydroxy silicone oil used for industrial silicone oil additives Distinguish, use dimethyl hydroxy silicone oil products containing impurities and catalyst residues for fabric synthesis, and the produced fabric products should not be in contact with the skin for a long time, and the effect on improving the friction and heat resistance of fabric products will also be affected

Abstract

The invention provides a preparation method of a dimethyl hydroxyl silicone oil purification adsorbent for fabric synthesis. The method comprises the following steps: adding 100 parts by weight of recombinant protein series high-flow-rate agarose gel, 0.1-1 part by weight of 2,3-dihydro-1,4-benzodioxy-5-carboxylic acid, 0.1-1 part by weight of N-sulfopropyl-3-methylpyridine p-toluenesulfonate and 0.5-2 parts by weight of ethyl 2-amino-1H-imidazole-5-carboxylate hydrochloride into 200-500 parts by weight of methylbenzene, performing separation on the reaction products, and performing drying to obtain the adsorbent.

Description

Technical field [0001] The invention relates to a preparation method of an adsorbent, in particular to a preparation method of an adsorbent for purification of dimethyl hydroxy silicone oil. Background technique [0002] Dimethyl hydroxy silicone oil is a chemical with a white uniform emulsion in appearance. It can be used as a mixed additive for other silicone oil products to enhance some of its physical and chemical properties. For example, it can be mixed with methyl hydrogen silicone oil emulsion to increase water resistance; It can also be used as synthetic fiber, silk, cotton and other fibers and fabrics to enhance the wear resistance and heat resistance of fabric products. [0003] CN101037505B discloses a production method of dimethyl hydroxy silicone oil. The dimethyldichlorosilane and sodium hydroxide solution are directly introduced into the reaction loop with the sodium chloride aqueous solution as the circulating liquid, including the circulating pump and the layerer,...
