Technical field
The present invention relates to oil absorption material field, and in particular to a kind of PLA is combined the preparation side of kapok fiber oil absorption material
Method.
Background technology
With the development for using and transporting of crude oil and various oils products, leaked by oily waste water, waste liquid, offshore oil
Turn into one of main Environmental Problems that nowadays we face etc. the water body oily pollution caused.In various oily sewage disposal methods,
It is most simple and a kind of wide variety of method to carry out adsorption recovery using oil absorption material.At present, the oil suction material used both at home and abroad
Material is to synthesize based on high polymer material, including polypropylene fibre, polyurethane foam, esters of acrylic acid and olefines oil-absorbing resin
Deng.These materials are almost using petroleum by-product as unique synthon entirely.Because oil is non-renewable resources and price day
Benefit is surging, and post processing is difficult, is also easy to produce secondary pollution problems.Therefore, people increasingly tend to when developing oil absorption material
Raw material is used as using cheap natural material.
Kapok original producton location is the ground such as China, Vietnam, Burma, India.Bombax cotton belongs to unicellular fruit fiber, with only
The big hollow morphosis of special thin-walled, primary chemical composition is cellulose, lignin, xylan, can be occurred with hydrophobic monomer
Polymerisation.Therefore, high oil-absorbing resin is developed using bombax cotton, not only can effectively utilizes resource present in nature, and
And the demand of sea, river and lake oily pollution to high oil-absorbent material can be met.But high oil absorption is prepared using bombax cotton
Resin is also rarely reported, and kapok fiber oil absorption material need further exploitation.
The content of the invention
According to problems of the prior art, a kind of absorbency capacity of this offer is big, swelling rate fast, biological degradability
The PLA of good, reproducible utilization is combined the preparation method of kapok fiber oil absorption material.
The present invention uses following technical scheme：
A kind of PLA is combined the preparation method of kapok fiber oil absorption material, comprises the following steps：

Step 2：Do not stop to stir PLA solution under 600r/min rotating speed, and n-hexane is added dropwise dropwise with liquid-transfering gun
Until solution untill clarify and become cloudy, as in refrigerator, stand after 24h and take out in -18 DEG C of environment, filter and vacuum is done
It is dry, obtain poly-lactic acid material；
Step 3：10g bombax cottons are weighed, are put into the NaOH aqueous solution that 300mL, mass concentration are 8g/L, and put
Put in the thermostat water bath that temperature is 90 DEG C, alkali process 2h, then cleaned repeatedly to neutrality with deionized water；
Step 4：Bombax cotton after alkali process is added to the sodium chlorite aqueous solution that 200mL mass concentrations are 1%
In, pH value of solution is adjusted to 4.5 with acetic acid, 1h is handled at 8 DEG C, then with distilled water cyclic washing to neutrality；
Step 5：Bombax cotton after step 4 is handled dries 1d naturally at room temperature, is then placed into 60 DEG C of electric heating
Dry to constant weight, then crushed with high speed disintegrator in constant temperature blast drying oven, cross 60 mesh sieves, obtain bombax cotton powder；
Step 6：2g poly-lactic acid materials and 2g bombax cotton powder are taken, is added in 70mL distilled water, is 500r/ in rotating speed
Under min, constant temperature at 5mL 0.045g containing benzoyl peroxide dimethylformamide and 1.1g styrene, 80 DEG C is sequentially added
2h is reacted, reaction is placed in air dry oven after product, filtering is washed with deionized after terminating, in dry to perseverance at 60 DEG C
Weight, obtains oil absorption material.
It is preferred that, the rotating speed of the high speed disintegrator described in step 5 is 5000r/min.
The beneficial effects of the present invention are：
1) poly-lactic acid material prepared by the present invention has the characteristic such as porous, biodegradable, is preferable oil absorption material.
2) oil absorption material produced by the present invention can substitute traditional synthesis polymer oil absorption material, and absorbency capacity it is big,
Swelling rate is fast.
3) pre-treatment is carried out to bombax cotton, the porosity of bombax cotton can be improved, further improve bombax cotton
Oil absorbency.
4) oil absorption material reproducible utilization of the invention, after discarded, can degrade in natural environment, biocompatibility
It is good, secondary pollution will not be produced.Suitable for oily waste water treatment, in terms of water body purification.
