specific Embodiment approach 1

[0015] Specific implementation mode 1: In this implementation mode, carbonized cotton fiber oil-absorbing material-urethane oil gelling agent composite oil spill treatment material is prepared according to the following steps:

[0016] Step 1: Preparation of alkyl carbamate oil gelling agent

[0017] Take 1 mol of toluene-2,4-diisocyanate (TDI) and 2 mol of dodecanol as raw materials, add them into 150 mL of chloroform, stir and mix evenly, and place them in a water bath or oil bath at 60°C for 24 hours. After the reaction, the solvent was distilled off under normal pressure at 90°C, and the concentrated solution was poured into a glass plate while it was still hot, and dried in vacuum at 135°C and -0.098MPa for 12 hours, then fully cooled and crushed. It is white powder.

Abstract

The invention discloses a method for preparing a carbonized cotton fiber oil absorbing material-carbamate oil coagulation agent composite oil spilling treatment material, and relates to a method for preparing an oil spilling treatment material. The method comprises the following specific operation steps: (1) preparing a carbamate oil coagulation agent; (2) preparing a carbonized cotton fiber oil absorbing material; (3) preparing the oil absorbing material-oil coagulation agent composite oil spilling treatment material. According to the method, a composite material for treating oil spilling is prepared by organically combining the oil coagulation agent which is a hot study point at present with the oil absorbing agent prepared from natural products, the composite material has the oil coagulation property of the oil coagulation agent and the oil absorption property of the oil absorbing agent, and the oil coagulation agent and the oil absorbing agent supplement each other and are in a relationship of mutual promotion.

Description

technical field [0001] The invention relates to a preparation method of an oil spill treatment material, in particular to a preparation method of a carbonized cotton fiber oil-absorbing material-carbamate oil gelling agent composite oil spill treatment material. Background technique [0002] With the increasing development of the oil industry, oil spill accidents occur frequently. According to statistics, 3,000 to 5,000 kt of oil spilled into the sea due to various accidents in the world every year has not only caused serious pollution to the marine ecological balance and ecological environment, but also caused a huge waste of resources. In 2013, the "11.22" Huangwei oil pipeline explosion accident occurred in Qingdao, causing crude oil to leak, and part of the crude oil spilled into the waters of Qingdao, which also brought great harm to the safety of people's lives and property, and this is only one of the oil spill accidents. "tip of the iceberg". How to effectively con...
