Problems solved by technology

At present, the commonly used oil-absorbing materials are mostly PP oil-absorbing felt products, but they have obvious disadvantages: first, the application performance of the water surface is poor, and it is easy to sink after a long time on the water surface; , bringing inconvenience to recovery and salvage
The general disadvantages of other oil-absorbing materials are poor oil-absorbing ability, unable to float on the water surface before and after oil-absorbing, and difficult to salvage, etc.

[0040] An oil-absorbing and decontaminating agent prepared from the following raw materials in parts by mass:

[0041] Organic monomer and styrene: 100 parts;

[0042] Polyvinyl alcohol: 1 part;

[0043] Hollow glass microspheres: 2 parts;

[0044] Dibenzoyl peroxide: 1 part;

[0045] Polynorbornene: 1 part;

[0046] Water: 1000 parts;

[0047] Wherein, the mass ratio of the organic monomer to styrene is 5:7; the organic monomer is octadecyl methacrylate.

Embodiment 3

Abstract

The invention discloses an oil-absorbing decontamination agent. The oil-absorbing decontamination agent is prepared by, by weight, 100 parts of organic monomer and styrene, 1-5 parts of polyvinyl alcohol, 2-10 parts of hollow glass beads, 1-3 parts of initiator, 1-5 parts of crosslinking agent and 1000-3000 parts of water, wherein the mass ratio of organic monomer to styrene is 5-7:5-7; the organic monomer is methyl methacrylate, octadecyl methacrylate or butyl acrylate. The oil-absorbing decontamination agent has the advantages that the oil-absorbing decontamination agent can condense oil to allow the oil to form solid jelly, the diffusion of spilled oil can be prevented effectively, and the oil-absorbing decontamination agent can float on the water surface for a long time before oil absorbing and is easy to recycle and fish.

Description

technical field [0001] The invention relates to a decontamination agent, in particular to an oil-absorbing decontamination agent and its preparation method and application. Background technique [0002] In recent years, with the rapid development of the petrochemical industry, in the process of exploration, exploitation, transportation, storage, processing and use, leakage accidents of crude oil and its products often occur, and the resulting environmental pollution is also becoming more and more serious. At present, my country's firefighting forces often use the principle of dilution to deal with oil spill accidents such as oil tanker rollovers and gas stations, and use water spray or sand as disposal methods. These methods have certain limitations. And in water body oil spill accident, also do not have a kind of feasible oil spill decontamination agent to occur. Therefore, the development of fast, efficient and widely used oil decontaminants has become an urgent problem t...
