Abstract
The invention relates to an oil absorption felt material with a skin/core composite structure. A compact non-woven material forms a skin layer, and a core layer material is composed of multilayers of loose non-woven materials. The skin layer material is a polypropylene melt-blown non-woven material with a gram weight of 15-50g/m<2>, the core layer material is a polypropylene/polyester mixed melt-blown non-woven material with a thickness of 3-5cm, the core layer material is coated by the skin layer material hermetically, and the periphery is sealed by means of hot pressing. For the oil absorption felt material, the skin layer material has high oleophylic and hydrophobic effects, when the oil absorption felt contacts oil, oil molecules can be led into the oil absorption felt inner core to be adsorbed by the inner core layer material, and water molecules cannot enter the core layer through the skin layer material, the core layer material can adsorb oil products with a self weight of 10-15 times, the oil products are sealed and stored in the oil absorption felt core layer and do not leak. The oil absorption felt provided by the invention has high oil absorption and oil holding performance.
Description
Technical field
The present invention relates to a kind of oil sorbent mat material with the absorption oil slick of skin/core composite construction.
Background technology
In recent years, the environment caused because of toxicity organic liquid and crude oil leakage, water resource pollution have become the significant problem paid close attention to both at home and abroad.After water surface generation leakage accident, large amount of organic can spread and form fine and close oil film on the water surface, oxygen content in water is sharply reduced, cause the multiple biologies such as planktonic organism, fish, shrimp because of anoxic death by suffocation, and then bring serious environment and biological disaster.Ai Kesenwadizi Oil Spills crude oil 1,100 ten thousand gallons in 1989, after Two decades years, U.S. Alaska State seashore is still covered with a large amount of oil; The Gulf of Mexico leakage of oil event occurred for 2010 has shocked All Around The World Shuan Ben factory of Jilin Petrochemical company in 2005 and has blasted, benzene pollutant flows into Second Songhua River, not only cause the riparian area such as Harbin City to be cut off the water, and pollutant go downstream and cause severe international influence comprehensively; Dalian oil pipeline blast in 2010 causes more than 1500 ton of crude oil leakage, and more than 50 square kilometre of marine site is polluted.Along with developing rapidly of Chinese society economy, oil-containing industrial sewage, oil-soluble dyes discharge of wastewater are more and more, and a small amount of oil slick often appears in the waters such as harbour.
The outstanding advantages that fiber-like oil absorption material is exceedingly fast with adsorption rate, oil suction multiplying power is high becomes the main flow of current oil suction product.Polypropylene (PP) nonwoven polypropylene fabric is a conventional class oil suction fibre material; PP fibre density is lower; floatability is on the water surface; and PP oil suction fibre adsorption rate is exceedingly fast; just can reach adsorption equilibrium in general a few minutes, become the sudden Oil spills of the reply water surface, tackle and the ideal material of large-scale recovery.
Existing polypropylene fibre asphalt felt product has good oil absorbency, but ubiquity holding oiliness can poor, defect that oil-water selectivity is poor.When asphalt felt oil absorption is more, pull at asphalt felt, when transporting transfer, oil product easily leaks and causes secondary pollution from asphalt felt.Polypropylene fibre asphalt felt product is being applied in oil slick removal process, if Long contact time water body can exist water imbibition to a certain degree, this causes asphalt felt oil absorbency to be affected.Still need at present and develop the polypropylene fibre oil suction product that oil absorbency is high, oil holdup is high, water imbibition is little, meet the requirement that spilled oil on water surface absorption is reclaimed.
Summary of the invention
The object of this invention is to provide a kind of oil sorbent mat material with skin/core composite construction.
The oil sorbent mat material with skin/core composite construction of the present invention is airtight clad structure, cortex is that fine and close nonwoven cloth material is formed, this nonwoven cloth material is the functionalization polypropylene fibre melt spraying non-woven fabrics of alkyl acrylate, and skin thickness is thinner, and grammes per square metre is at 15 ~ 50g/m
2; Inner core layers material is that multilayer bulk material is formed, and this multilayer bulk material is polypropylene fibre/terylene mixing melt-blown nonwoven cloth material, and thickness is 3 ~ 5cm; Core material is airtight coated by cortical material, and cortical material is sealed by hot pressing mode.
The non-woven fabrics oil sorbent mat material of this composite construction, cortex and core material play different effects in oil-absorbing process, cortical material has higher oleophilic drainage effect, when asphalt felt contacts with oil, cortex non-woven fabrics is owing to having lipophile, oil molecule can be imported to asphalt felt inner core, by inner core layers materials adsorption, and hydrone cannot enter sandwich layer by cortical material.Core material has high oil suction multiplying power, can adsorb the oil product of deadweight 10 ~ 15 times.After oil product enters sandwich layer, because cortical material has property, oil product can not leak out again, and is sealed up for safekeeping in asphalt felt inner core layers, ensures that asphalt felt has higher oil absorbency and holding oiliness energy.

Fig. 1 is the oil sorbent mat material structural representation with skin/core composite construction.
Fig. 2 is the generalized section of the A-A of Fig. 1.
Detailed description of the invention
The present invention is the asphalt felt with skin/core composite construction, comprises fine and close polypropylene fibre melt spraying non-woven fabrics cortex 2 material, loose polypropylene fibre/terylene melt spraying non-woven fabrics sandwich layer 3 material.Cortex 2 material is coated on outside sandwich layer 3 material, and cortex 2 material seals surrounding by hot pressing mode.
