Description
Technical field
The present invention relates to Material Field, particularly a kind of environmental protection expanded polypropylene and polymeric absorbent matrix material and preparation method thereof that can reuse.
Background technology
Oil has " black gold ", the title of " economic blood ", is widely used in the every field of national economy.Fast development along with China's economy and the increase to energy demand, its range of application is also expanded in continuation, and consumption also increases increasingly.In crude oil production, processing, transport, refining and use procedure, owing to being subject to the restriction of state of the art and treatment technology, a large amount of waste water containing oily substance, waste residue are inevitably discharged in water body, cause great destruction to the marine eco-environment and freshwater environment.Oil spilling in water, oil stain not only reduce the quality of ocean and fresh water environment, affect the circulation of food chain, destroy the eubiosis, also threaten the health of the mankind, and will address these problems, just in the urgent need to developing efficient, durable, clean oil absorption material.
Oil absorption material mainly can be divided into three major types, i.e. inorganic oil absorption material, organic synthesis oil absorption material and organic natural oil absorption material.Expanded polypropylene foam is a kind of high crystallization composite material of performance brilliance, compared with other TPO, polypropylene has higher rigidity, excellent mechanical property, good thermotolerance and chemical stability are the excellent materials for industrial uses such as filtering separation, not only recyclable recycling, and can natural degradation, can not white pollution be caused, thus be called as " green " foam.Polypropylene foam, due to its good mechanical property, excellent resistance toheat and the character being beneficial to environment protection, is the foam materials of new generation after traditional polystyrene foam, polyurethane foam and polyethylene, has a wide range of applications.But this material is as sorbing material, have some shortcomings, such as there is gravity, to protect oily rate lower, after absorbing, extruding is leaked again, and due to vesicular structure, specific surface area is large, the volatility of absorbed high volatile volatile liquid cannot be suppressed, undesirable etc. to poisonous explosive chemical treatments effect.Methyl acrylic ester high oil absorbing resin is one of the study hotspot in oil absorption material field in recent years, methyl acrylic ester high oil absorbing resin is the function that Van der Waals force by producing between the oleophilic group in molecular chain and oil molecule realizes oil suction, oil product difficult drop-off after resin material oil suction, protect oily rate high, the advantage of oil-absorbing resin with expanded polypropylene foam combines by imagination, propose in expandable polypropylene resin process, polyacrylic resin to be cross-linked wherein, in order to improve material Oil keeping energy, novel material has just possessed the two-fold advantage of physical adsorption and chemical absorption.
