The invention relates to the field of materials, and particularly relates to an adsorption material suitable for a water-oil mixed environment. The adsorption material consists of an oil holding layer and surface layers positioned at two sides of the oil holding layer, wherein the oil holding layer is a coarse polypropylene fiber melt-blown layer containing hydrophilic particles; the surfaces layers are formed by compressing inner layers and outer layers; the inner layers are fine polypropylene fiber melt-blown layers; the outer layers are thin non-woven cloth layers which have the surface density of 8-30g/m<2> and cannot defiber easily; compression patterns are also distributed on the outer layers; the inner layers and the outer layers are combined together via a plurality of pressing points. According to the invention, the oil adsorption material of a sandwiched structure, which has two compact surfaces and is loosened in the middle and variable in density, is prepared by adopting a melt-blown formation technique in combination with an ultraviolet compression technique; the hydrophilic particles are added in the melt-blown formation process, the prepared coarse polypropylene fiber also has a certain water absorption function on the basis of keeping the original high oil adsorption capability, and the adsorption material is suitable for specific water-oil mixing production links.
Description
Technical field
The present invention relates to Material Field, be particularly a kind ofly suitable for the sorbing material that uses under water oil hybird environment.
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.In view of above reason, need badly and invent one and can oil suction can absorb water again, and absorbability is strong, lock water locks the good sorbing material of oily ability.
Summary of the invention
Technical problem to be solved by this invention is to provide and is suitable for the sorbing material that uses under water oil hybird environment, and this sorbing material can absorb water again in oil suction, and absorbability is strong, and it is good that lock water locks oily ability; And the surface fiber difficult drop-off of this material, be adapted at using in the higher environment of purity requirements.
For solving the problem, the invention provides and be a kind ofly suitable for the sorbing material that uses under water oil hybird environment, described sorbing material by holding oil reservoir and being positioned at the top layer of holding oil reservoir both sides and forming, wherein, described in hold oil reservoir be crude polypropylene fiber meltblown layer containing hydrophilic granules; Described top layer is formed by internal layer and outer compacting, and internal layer is thin polypropylene fibre meltblown layer, outer for surface density be 8-30g/m
2the thin nonwoven layers of not easily defiber, skin is also distributed with press pattern, and skin and internal layer are combined with each other by several pressure points.
Further, described crude polypropylene fiber meltblown layer is made up of the crude polypropylene fiber containing hydrophilic granules, and described hydrophilic granules is selected from silica and/or iron hydroxide; Described thin polypropylene fibre meltblown layer is made up of thin polypropylene fibre; The press pattern that described skin distributes is combined by pressure point, and described press pattern is rectangle, and the shape of pressure point is circle, rectangle or polygon.
Further, the diameter of described thin polypropylene fibre is 2-4 μm, and the diameter of described crude polypropylene fiber is 5-10 μm; The described thickness holding oil reservoir is 20-60mm.
Due to technique scheme, beneficial effect of the present invention is:
1, the present invention adopts melt-blown formation combine with technique ultrasonic wave compact technique to make two sides densification, the middle polypropylene fibre melt-blown non-woven oil absorption material dredging the sandwich of the variable density sent, hydrophilic granules is added in melt-blown forming process, make the crude polypropylene fiber prepared also have certain absorbent function on the basis keeping original strong oil absorption, be applicable to the specific production link of water oil mixing.
2, the top layer of sorbing material of the present invention is formed by internal layer and outer compacting, wherein, internal layer is the compact texture that fine fibre is formed, skin is the non-woven fabrics of not easily defiber, this structure makes sorbing material have the specific area of super large and abundant capillary structure, can keep abundant capillary oil suction effect, keep higher speed of oil absorption, can promote again the holding oiliness of oil absorption material, lock water protects oil, and after preventing materials adsorption, guttation tells oil.
3, skin of the present invention is the thin nonwoven layers of not easily defiber, by external sheath internal layer, in use, there is voidage is large, outward appearance is bulk internal layer do not produce with object and rub, fiber can not come off, and is highly suitable in the higher environment of purity requirements and uses.
In sum, sorbing material of the present invention has water suction oil suction, not easily defiber, feature easy to use; The press pattern on its surface makes product attractive in appearance, durable.
