Problems solved by technology

It is used to filter out poisonous gas, refine petroleum and vegetable oil, prevent viruses and molds, recover gasoline in natural gas, sugar and other colored substances for decolorization, etc. After the adsorption is carried out for a certain period of time, the surface of the adsorbent will be covered by the adsorbent, making it The adsorption capacity drops sharply. At this time, the adsorbed substance needs to be desorbed to regenerate the adsorbent. The operation is cumbersome and consumes resources.

Abstract

The invention discloses a light graphene absorbing material. The light graphene absorbing material comprises the following materials by weight: 5-8 parts of light calcium carbonate, 110-130 parts of activated graphene, 1-2 parts of lauryl trimethyl ammonium chloride, 0.1-0.3 part of butylmercaptooxo stannane, 2-3 parts of propylene glycol methyl ether acetate, and 1-2 parts of sodium alginate. Thegraphene is firstly activated by using the stearic acid, the light calcium carbonate is dispersed in an amide solution and blended together with the activated graphene, a calcium carbonate compoundedgraphene material is obtained, the adsorptivity of the product is good, the stability is high, and the repeating utilization factor is high.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a light graphene adsorption material and a preparation method thereof. Background technique [0002] The main indicators to measure the adsorbent are: adsorption capacity for different gas impurities, wear rate, bulk density, specific surface area, crushing strength, etc. It is used to filter out poisonous gas, refine petroleum and vegetable oil, prevent viruses and molds, recover gasoline in natural gas, sugar and other colored substances for decolorization, etc. After the adsorption is carried out for a certain period of time, the surface of the adsorbent will be covered by the adsorbent, so that The adsorption capacity drops sharply. At this time, the adsorbed substance needs to be desorbed to regenerate the adsorbent. The operation is cumbersome and consumes resources. Contents of the invention [0003] The purpose of the present invention is to provide a light graphen...
