Description
Technical field
The present invention relates to sorbing material technical field, and in particular to a kind of method that utilization eucalyptus barks prepare oil suction fibre.
Background technology
With industrial expansion, the pollution that waste water, waste liquid containing greasy dirt, offshore oil leakage etc. are caused can not be ignored,
40% oily pollution comes from oil tanker and shipping, such as oil carrier, tank leakage accident wherein in water body.When oil leak occurs in ocean,
Usual 1 ton of oil can at sea form covering 12km2The oil film of scope, the large area oil film being consequently formed will obstruct normal sea
Gas exchange process, makes unusual weather conditions, influences the circulation of biological chain, so that marine ecology balance is destroyed, to marine environment and the mankind
Health care belt endangers.When oil spilling enters city river, one layer of oil film will be formed in the water surface, the mistake of water reaeration is hindered
Journey, the dissolved oxygen that part oil spilling also will be consumed largely in water due to oxidation causes water hypoxia, and fish are dead, water quality by
Destruction.When oil leak occurs on land, plant, animal and the region used of locality can be influenceed, soil texture is destroyed so that
Its function reduction, serious harm is produced to the ecosystem of soil.Therefore, when oil spill accident occurs, if without timely
Effective processing, will have a strong impact on water quality, destroy ecological environment, and influence is supplied water and aquatic resources, or even harm city dweller
It is healthy.
At present to the processing method of oil pollution accident, mainly there are fence method, dispersion method, absorption method, freezing method, detergent
In method, filtration method etc., these processing methods, most viable is to carry out adsorption recovery to oils using oil suction fibre.Oil suction fibre
Kind it is more, using it is most be the oil suction fibre that is made using synthetic organic polymer material and natural fiber as raw material.Close
It is mainly polypropylene synthetic fibers into polymer, polypropylene synthetic fibers are not degradable, post processing is produced to environment
Secondary pollution, it will be gradually eliminated；Also have at present and be made using string such as cotton, mestha and animal origin such as wool
Oil suction fibre is applied in oil removing research, but these costs of material are higher, are not suitable for largely using for a long time.
Eucalyptus（EucalyptusrobustaSmith）Also known as You Jiali trees, are the general designations of Myrtaceae eucalyptus plant,
There is more than 90 country to have cultivation eucalyptus.Data is reported according to the study, and bark yield can be multiplied by coefficient with log yield
0.13 tries to achieve.In 2016, single Guangxi just generated about 7,500,000 m3Eucalyptus bark.At present, eucalyptus barks some be used for give birth to
Wood-based plate is produced, but is burnt mostly as fuel, what is had is even taken as rubbish and throws away, and large area is not only taken up so
Stacking place, grow pest and disease damage, or even lead to fire, cause the great wasting of resources and environmental pollution.The comprehensive fiber of eucalyptus barks
The content height of element and cellulose, its surface has microcellular structure, capillary attraction effect strong, with the big and preferable suction of specific surface area
Attached function；Simultaneously also containing a certain amount of lignin, fatty acid ester, resin etc. be water insoluble and thing that have certain lubrication
Matter, makes the characteristics of eucalyptus barks have oleophylic and be hydrophilic, develops oil absorption material the characteristics of how using eucalyptus barks, will be that eucalyptus barks are ground
The important directions studied carefully.
The content of the invention
In order to solve the above problems, the present invention provides a kind of method that utilization eucalyptus barks prepare oil suction fibre, is by eucalyptus

（2）Brooming is discongested：Material after hydrolyzing boiling processing is put into defibrator, washed according to a conventional method, is sieved,
Dry, obtain pulp；
（3）Purge drying：By pulp according to a conventional method be dispersed in water stand or with scummer remove pulp in the grains of sand, trifle
Son and the eucalyptus barks impurity for not steaming solution, then handsheet, is placed in 60 DEG C of air blowers and air-dries, and obtains the eucalyptus barks that moisture content is less than 8%
Fiber；
（4）Oleophilic drainage is modified：Eucalyptus hide fiber is mixed with oleophilic drainage agent, soaked, is dehydrated, dries, produces oil suction fibre.
It is used as further illustrating for the present invention, step（4）The oleophilic drainage modification procedure can also use following steps
Replace：Eucalyptus hide fiber is placed in muffle furnace, with 3 DEG C/min programming rate, be warming up to 300~350 DEG C and be incubated 1~
1.5h, produces oil suction fibre.
It is used as further illustrating for the present invention, step（4）The oleophilic drainage agent includes the raw material of following parts by weight：Gu
100~150 parts of body paraffin, 50~70 parts of stearic acid, 10~12 parts of emulsifying agent, 500~800 parts of water, appropriate potassium hydroxide.
As further illustrating for the present invention, the preparation method of the oleophilic drainage agent is:Take solid paraffin, stearic acid and
Water is placed in reactor, is heated to 50~60 DEG C, when solid paraffin and stearic acid start fusing, stirring, when solid paraffin and
After stearic acid is completely dissolved, emulsifying agent is added, continues to stir and be warming up to 75~90 DEG C, potassium hydroxide regulation reaction solution is added
PH value reacts 25~60min, that is, obtains oleophilic drainage agent to 8~9.
As further illustrating for the present invention, the emulsifying agent is Isosorbide-5-Nitrae-morpholine and fatty alcohol and oxirane
