Description
Technical field
The present invention relates to advanced composite material (ACM) field, particularly to a kind of compound absorbing material being added with glass fibre and
Its preparation method.
Background technology
High oil-absorbent material is that occur in the 60's of 20th century, the nearly more than ten years obtain developing rapidly a kind of can oil suction material
Material.It is initially to make numerous researchers produce great interest to it due to the needs of oily pollution improvement.With industrial
Development, the pollution that waste water containing greasy dirt, waste liquid, offshore oil leakage etc. cause can not be ignored, does not solve these problems, will
Cause bigger destruction to the earth and the mankind.Oil-absorbing resin is to aid in people and solves one of important method of this problem.Oil suction
One process being developed to high-performance type from tradition of the development experience of material.Initially people utilize the porous such as sponge, clay
Material carrys out oil suction, but result is unsatisfactory, and this oil absorption material has obvious shortcoming:(1) oil absorption is little, oil suction
Multiplying power is less;(2) oil-water selectivity is not high, often also absorbs water while oil suction;(3) after oil suction, Oil keeping is poor, slightly pressurizes
Will oil leak again.The presence of these shortcomings makes their application be restricted.Later, people were subject to surfactant table
Face changes sexual enlightenment, makees oil absorption material with oil sucting pad, and such as polypropylene fibre asphalt felt is with isotactic polypropylene resin as raw material, adopts
Spin connection one step and become net, more prepared through needle felting, oil sucting pad is oleophilic substance in itself or is oleophylic thing after modified
The oil absorbency of matter, therefore oil sucting pad and oil-water selectivity all increase, but the problem of oil leak again is but under plus-pressure
Still can not solve.Recent years, researchers are subject to some theoretical the inspiring of high hydroscopic resin, make oil absorption material to
High oil-absorbing resin develops.The more high oil-absorbing resin of research is often the polymer of low cross-linking at present, and it with lipophile monomer is
Base unit, through appropriately crosslinked composition network structure, the oil of absorption is saved in this network with Van der Waals force.This oil suction
Material oil suction multiplying power is high, oil-water selectivity is good, and protect oil performance greatly improves, and is difficult oil leak again, is a kind of high performance
New material.
Research to high oil-absorbing resin field still has very big development space, and research from now on will be entered towards multiple directions
OK, such as:(1) theoretical research of the aspect such as relation between oil suction thermodynamics and kineticses, resin structure and performance is not even
Many.If can make in this respect deeper into exploration will produce directive function to the research and development of oil-absorbing resin, for preferably
Exploitation novel oil absorption material provides solid theoretical foundation, thus improving oil suction multiplying power and swelling rate further.(2) resin
Regeneration.If resin oil suction under the conditions of a certain, and oil can be discharged quickly in an other condition,
Resin and the cycling and reutilization of oil just can be reached.Just the current data grasped is seen, the research of this respect is few, does not almost have
Have.(3) resin oil suction post processing.For the process occasion being not desired to using resin slow-release, after resin oil suction, how to process band
The resin of oil is a field studying less.It is substantially fired and abandons by existing method.Whether can find out more effectively
Resin oil suction post-processing technology, effective use of energy sources also will be a significantly direction.(4) raw material sources problem.Mesh
The high oil-absorbing resin majority of front research is to start to synthesize from monomer, if energy twice laid, by waste material such as gin waste material
As raw material, prepare high oil-absorbent material, the aspects such as environment, the energy are all made great sense.(5) application is further
Developing.High oil-absorbing resin plays a role in many fields, but still has many blank fields to await development, for example can be by it
For being used for oil removing in cosmetics;Synthesizing new biology oil absorption material, can be used for medical science aspect, solves mistake in blood of human body
The problems such as surplus blood fat or obesity.(6) development of compound oil absorption material and exploitation.
However, current high resin oil absorption material often price is higher, be unsuitable for large-scale use.Therefore, develop one kind
Cheap, and equally hold oily effect in oil absorbing effect, machinery, protect the many-sides such as oily effect, absorption rate and possess good characteristic
Compound absorbing material to replace high resin oil absorption material just to seem particularly significant.
