Abstract
The invention discloses a high-oil-absorptivity resin and a preparation method thereof. The high-oil-absorptivity resin is mainly prepared from 100 parts of monomer, 5-30 parts of emulsifier, 10-30 parts of crosslinking agent, 1-3 parts of oxidizer, 1-4 parts of reducer and 500-900 parts of deionized water. The preparation method comprises the following steps: adding the emulsifier and crosslinking agent into the monomer, stirring uniformly, introducing nitrogen, dropwisely adding the deionized water to obtain an emulsion, adding the initiator into the obtained emulsion, reacting for 4 hours, and carrying out vacuum drying on the product to obtain the high-oil-absorptivity oil-absorbing resin. The high-oil-absorptivity resin has high porosity and can be recycled 4-8 times. The method has the advantages of mild reaction, simple process and low cost.
Description
Technical field
The present invention relates to a kind of preparation method of high oil absorbing resin.
Background technology
All the time, environmental problem is all the focus that the whole world is paid close attention to.Walk sustainable development path, the ecotope improving the earth is the common recognition of the people of other countries.But in today of science technology and economy high speed development, environmental pollution is day by day serious, as the crude oil leakage of marine transport oiler, the cleaning of ship cargo hold and the leakage etc. of the petroleum product entered in ocean and offshore field and pipeline causes large-scale sea to pollute, many marine organisms and resource are subject to serious threat, not only cause the deterioration of ecotope, and have impact on the economic activity of coastal resident.Common material oil number is little, protects oily rate variance, oil suction also absorbs water simultaneously, be not suitable for the process to marine floating oil, offshore oil leakage accident.
High oil absorbing resin is a kind of threedirection polymerization resin with three-dimensional netted chemically crosslinked structure, have that oil suction kind is many, oil number is large, reclaim feature easily, be widely used in sea pollution by oil process, oil product is revealed, be particularly useful for the large-scale oil pollution on sea.
Summary of the invention
The object of the present invention is to provide the resin that a kind of oil absorptiveness is good.
In order to realize above order, the technical solution adopted in the present invention is: a kind of high oil absorbing resin, adopts the main raw material of following weight part: monomer 100 parts, emulsifying agent 5 ~ 30 parts, linking agent 10-30 part, 1 ~ 3 part, oxygenant, reductive agent are 1 ~ 4 part, deionized water 500 ~ 900 parts.
The preparation method of described resin:
Take raw material according to the above ratio, emulsifying agent, linking agent are added in monomer, stir, pass into nitrogen, evenly drip deionized water under high velocity agitation, after dropwising, add oxygenant, reductive agent, react 4 hours at 20 ~ 50 DEG C, product, through vacuum-drying, can obtain the oil-absorbing resin with high oil absorbency.
Described monomer is the mixture of any one or they in acrylic ester monomer and ethylacrylic acid esters monomer.
Described acrylic monomer is: n-butyl acrylate or Process Conditions of Cetane Acrylate; Described ethylacrylic acid esters monomer is: the positive butyl ester of ethylacrylic acid or ethylacrylic acid hexadecyl ester.
Described oxygenant is that persulfuric acid is received, described reductive agent is S-WAT.Described linking agent is glycol diacrylate.
Shown emulsifying agent is tween 80.
The mechanism of high oil absorbing resin of the present invention: water soluble, redox system trigger monomer carries out Raolical polymerizable at ambient temperature, prepares the resin with tridimensional network.
Compared with the prior art the present invention has the following advantages: have very large porosity, reticulated structure has good connectedness, therefore have fast and efficiently oil absorbency, overcome the slow problem of common oil-absorbing resin oil absorbency, when tackling the oil pollution of emergency case, there is good effect.Reaction temperature of the present invention and, preparation method is convenient, environmental protection no waste produce; In addition, reusable 4-8 time of gained resin of the present invention, after Reusability, absorbed dose remains unchanged substantially, overcomes the shortcoming that general resin repeatedly uses rear degradation, thus has saved cost.
