Description
Technical field
The present invention relates to oil absorption material preparing technical fields, and in particular to a kind of preparation method of degradable oil absorption material.
Background technology
In recent years, the frequent generation of offshore oil leakage accident and a large amount of discharges of industrial oily wastewater so that grease point
Become focus of people's attention again from problem.Oily wastewater source is wider, such as Oil spills, land exploitation oil ore, food
Many industries such as product, weaving, mechanical processing all discharge a large amount of oily wastewater into environment, and either industrial oily wastewater is still
The arbitrary discharge of life oily wastewater all causes prodigious pollution to production and living environment, and the environmental problem thereby resulted in has not been allowed
Ignore.
In recent decades, the research of oil absorption material is rapid with application development, and purposes is also very extensive.Traditional oil suction material
Material, such as sponge, clay porous mass are widely used, although these materials have preferable oil absorbing effect, due to material
The structural property of material itself makes traditional oil absorption material have the shortcomings that oil absorption is little, oil-water selectivity is not high, usually oil suction
While also absorb water, and service life is short.It is just being answered extensively using artificial synthesized high molecular polymer as new oil absorption material
With, such as polyurethane, polyethylene, polypropylene, this kind of polymer oil absorption material is big with oil absorption, the good advantage of oil absorbing effect,
However this kind of material is poisonous and hazardous petrochemical industry material mostly, and it is not degradable after oil suction, handle the overall cost of waste
Higher, reusability is poor, the problems such as being easy to bring secondary environmental pollution.
It can effectively overcome traditional natural organic oil absorption material by the novel oil absorption material that base material is developed of natural materials
Defect, and have the characteristics that the rate of adsorption is fast, oil absorbency is high, biodegradable, people are paying more and more attention to it.Generally
Ground, such oil absorption material mainly using agricultural wastes as raw material and it is hydrophobically modified be prepared, such as modified bagasse, modified rice
Shell etc..Mainly oil is adsorbed by the capillarity in the gap of material surface and tube chamber, wherein material composition ratio pair
Its oil absorbency is affected.Compared with polypropylene, the adsorption capacity of these modified natural materials is stronger, and rice husk and bagasse
As agricultural waste material, derive from a wealth of sources, it being capable of natural degradation.But due in the cellulose of biological material hydroxyl it is more,
There is larger hydrophily, cause its oil absorption little, oil suction multiplying power is smaller, and oil-water selectivity is not high, often while oil suction
Also it absorbs water, reduces its oil suction and oil-retaining, fine and close pore structure limits the raising of oil absorbency, in addition, these are passed
System organic adsorption material has a single function, it is impossible to be used in extreme harsh environment, such as superhigh temperature, ultralow temperature and acidity environment, limit
Their applications in aerospace, industry and daily life are made.
Therefore, environmentally protective, biodegradable, efficient oil absorption material are developed as raw material using the compatible substance of environment,
It is had a very important significance for improving marine environment and ecological environment.
