Abstract

The invention discloses high-adsorbability resin which comprises the following raw material components in parts by weight: 1-15 parts of water, 15-30 parts of methacrylate, 5-15 parts of acrylate, 15-50 parts of acrylate and 10-30 parts of styrene. The high-adsorbability resin also comprises a pore-foaming agent and an initiator. The product is stable in polarity, easy to store and moderate in viscosity, has the advantages of being high in adsorption rate, high in adsorption capacity, good in mechanical strength, simple in regeneration mode and the like, and can effectively adsorb an organic poison solvent and solve the leakage problem of the organic poison solvent. The invention further discloses a preparation method of the high-adsorbability resin. The preparation method is simple to operate, safe in preparation process, free of by-products, high in repeatability and beneficial to large-scale preparation. The invention also discloses an application of the high-adsorbability resin inorganic poison adsorption. The product can be used for adsorption treatment of organic toxicants such as acetic acid short-chain ester, benzene compounds and chlorides.

Description

technical field [0001] The invention belongs to the field of adsorption resins, and in particular relates to a highly absorbent resin and a preparation method thereof. Background technique [0002] With the rapid development of my country's social economy and chemical industry, the scope of application of chemicals has become more and more extensive. At the same time, environmental pollution caused by oily sewage, waste liquids and industrial accidents such as the leakage of ethyl acetate has become increasingly serious. At present, traditional methods are mainly used for the disposal of such oily pollutants, such as activated carbon adsorption, biodegradation, flocculation, or the use of oil dispersants. Among them, activated carbon is widely used, but the capacity of activated carbon adsorption is low. Short service life. Compared with these traditional treatment methods for low-viscosity oils, super oil-absorbing resins can modify polymer resins according to the types of...
