Description
Technical field
The present invention relates to Material Field, particularly a kind of preparation method of variable color polymer oil absorption material and variable color adsorption cotton.
Background technology
Various oils, hydro carbons, in the process exploited, produce, transport and use, have the possibility that leakage occurs, once leak, will pollute the environment, and bring harm to human health.Particularly marine oil overflow accident can cause the destruction of marine ecology, and along with contingent fire, can produce a series of secondary pollution by atmosphere pollution.Process the oil pollution on the water surface or soil, use oil absorption material to be the most frequently used method.
Oil absorption material common at present has two large classes, and a class is the oil absorption material of chemical synthesis, as polypropylene synthesis sorbing material, have good hydrophobic and lipophile, but these oil absorption material oil absorbencyes is not good, and expensive.Another kind of is natural oil absorption material, and as porous positions such as raw cotton, agricultural crop straw, wood fibre, wools, oil suction multiplying power is better.
Melt spraying non-woven fabrics is a kind of oil absorption material of chemical synthesis, is widely used in industrial adsorption.Non-weaving cloth a kind ofly does not need to spin cotton and weave cloth and the fabric that formed, just textile staple or long filament carried out orientation or random alignment, form fibre net structure, then adopts machinery, the method such as hot sticky or chemical reinforces and form.It is not by the yarns interwoven of one one, knits together, but fiber is directly bonded together by the method for physics.Non-weaving cloth breaches traditional weaving principle, and have that technological process is short, speed of production is fast, the features such as output is high, cost is low, purposes is wide, raw material sources are many.The non-woven fabrics fiber prepared with melt-blown process is ultra-fine, voidage large, and absorbent is strong, and imbibition is indeformable, is widely used in the fields such as oil spilling absorption, leakage of chemical liquid absorption, plant maintenance, environmental protection.
On market there is following defect in the existing melt spraying non-woven fabrics for industrial adsorption: 1. because non-woven fabrics fiber is very thin, easily rupture, surface fiber easily comes off, and thus cannot require to use in higher environment in purifying degree; 2. mainly in order to absorb, pure oil plant designs the oil absorption material used in industrial production, therefore stronger lipophilic-hydrophobic property is shown as, but in some specific production link, often there is the situation of water oil mixing, for this situation, need first to use oil absorption material oil suction, then get water wetted material water suction, operating process is more loaded down with trivial details, wastes time and energy.3. existing sorbing material is in use, can not present intuitively adsorbance number, absorption saturated front and back there is no significant change, make troubles to use.
In view of above reason, need badly and invent one and can oil suction can absorb water again, and can intuitively show whether adsorb, sorbing material that whether adsorbance saturated.
Summary of the invention
Technical problem to be solved by this invention is to provide variable color adsorption cotton, and this sorbing material can absorb water again in oil suction, can change color according to the change of adsorbance, and person easy to use judges whether to need to change sorbing material; Meanwhile, the surface fiber difficult drop-off of this material, is adapted at using in the higher environment of purity requirements.
