Description
Technical field
The invention belongs to filed of functional, and in particular to a kind of porous easily reclaims high oil-absorbing resin and its preparation side
Method.
Background technology
In recent years, going deep into exploitations such as oil explorations, problem of environmental pollution and oil-containing that oil leak etc. is caused
The destruction of waste water, waste liquid to water resource is increasingly aggravated, and is caused and is had a strong impact on to human lives.Therefore it is excellent in the urgent need to developing
Oil absorption material, to tackle the oil pollution problem of current sternness.
High oil-absorbing resin is the low crosslinking degree polymer that lipophile monomer is constituted.It is intermolecular that there is three-dimensional cross-linked netted knot
There is certain micropore structure, inside, can be swelled decades of times oil product.It can be largely classified into inorganic oil-absorbing resin and organic oil suction
Resin, wherein organic oil-absorbing resin can be divided into natural absorbent-type and the class of synthesis type two again.But current common high oil absorption tree
There is the rate of adsorption slowly in fat, the low problem of efficiency, and this just greatly limit its application.In order to improve asking for existing high oil-absorbing resin
Topic, is done numerous studies, and one of them is exactly by introducing the high oil-absorbing that physical-chemical composite crosslinking is synthesized
Resin, its swelling rate will be significantly faster than that the high oil-absorbing resin that single chemical crosslinking synthesis is obtained.
Resin after oil suction is through regeneration treatment, and the recyclable institute's oil suction product of one side, it is to avoid secondary pollution are on the other hand high to inhale
Oleoresin is reusable.In order to avoid the secondary pollution that resin is caused after oil suction, the resin after oil suction need to be carried out at regeneration
Reason, traditional high oil-absorbing resin is last low by the high oil-absorbing resin difficult, reuse ratio that is recycled after repeated use.
