Preparation method of mushroom-stem-imitated directional oil absorption material

Abstract

The invention relates to the technical field of paint, and discloses a preparation method of a mushroom-stem-imitated directional oil absorption material. The method includes the steps: cleaning freshmushrooms or coprinus comatus, treating materials by liquid nitrogen, and performing vacuum drying on the materials for 24-36 hours in a freeze dryer; soaking the cleaned and dewatered dry mushroomsinto mixed solution for 10-11 hours, and stirring mixture by a magnetic stirrer at the rotating speed of 200r / min; calcining the mushrooms for 3-4 hours at the temperature of 500 DEG C, and fluoridizing the calcined mushrooms by a chemical vapor deposition method to obtain a hydrophobic silicon dioxide biomimetic mineralization mushroom stem structure; dissolving chitosan in glacial acetic acid, and preparing directional porous size-adjustable macromolecule hydrophobic oil absorption material by an ice formwork method and a fluoridizing method. An oriented porous structure can have an orientation accelerated absorption effect on liquid, good oil-water separation effects can be acquired after fluoridizing, size-adjustable oriented porous oil absorption material macromolecule material is prepared by combining the ice formwork method, oil absorption effects of the material is further optimized, and the material is reusable.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method of a directional oil-absorbing material imitating mushroom stems. Background technique [0002] With the development of industry and technology, the application of petroleum plays an important role in the current social production and life, thus promoting the large-scale flow of petroleum around the world, and the transportation of petroleum can be divided into land transportation, which mainly takes Pipeline transportation, because pipeline transportation has good timeliness and can not be restricted by day, night and weather, but its flexibility is poor; sea transportation is by sea, using large oil tankers, etc. The sea freight is low, but the transportation volume is large and the time is long long.

In addition, the oil production used in the world mainly comes from the Middle East, so ocean transportation of oil has become the main mode of transportation. However, affected by natural conditions and man-made accidents, oil spills often occur on tankers transporting oil
