Abstract

The invention discloses an attapulgite high-efficiency oil stain adsorbent, which comprises the following raw materials by weight: 50-70 parts of modified attapulgite, 5-10 parts of coke, 3-6 parts of lignite, 1-3 parts of sodium carboxymethylcellulose, 10-20 parts of a clay additive, 10-16 parts of an ore powder additive, 8-12 parts of tetrabutyl titanate, 20-30 parts of anhydrous ethanol, 5-10 parts of calcium carbonate fiber, and 2-4 parts of activated carbon. The attapulgite high-efficiency oil stain adsorbent provided by the invention has good adsorption properties in various fields, especially in oil stain treatment aspect, is in favor of rapid cleaning of oil stain pavements, and has high adsorption efficiency. Adsorption treated gel-like objects are easily collected, have no damage to the pavement, and are free of environmental pollution. At the same time, the preparation method provided by the invention has the advantages of low material cost, easily available raw materials, concise process, and has high use value and good application prospect.

Description

technical field [0001] The invention relates to the technical field of adsorbents, in particular to an attapulgite high-efficiency oily dirt adsorbent and a preparation method thereof. Background technique [0002] The surface of cement pavement, modified asphalt pavement or road toll station ground is often polluted by various oil, carbon deposits, grease, paraffin, dyes, mildew and other dirt leaked from motor vehicles; especially after traffic accidents, damaged A large amount of cooling water, diesel or gasoline, and engine oil will flow out of vehicles, causing a large area of ​​road surface to be seriously polluted by oil and water pollutants. On the road in the town, there are fruit vendors setting up stalls during the day, and some peels and fruit juices are left on the road, and the supper stalls are sold. Food residues and oils cannot be cleaned up for a long time, forming a thick layer of oil and sewage on the road. . After the road surface is seriously polluted...
