Description
Technical field
The present invention relates to a kind of hydroxyapatite overlong nanowire magnetism incombustible papers, belong to nano material and speciality paper neck
Domain.
Background technology
With economic and industry continuous development, by the oily pollution of the initiations such as industrial production, daily life and crude oil leakage
Problem has been to be concerned by more and more people.It, not only can be serious often containing some toxic chemical substances in these oily waste waters
People's health is damaged, while ecological environment can also be polluted.The U.S. Mexico gulf crude oil leakage thing occurred in 2010
Part causes huge economic loss, causes serious pollution simultaneously for the ecological environment of surrounding area, causes the world
The highest attention of society.
At present, there are many materials to be used for water-oil separating and greasy dirt absorption, such as activated carbon, macromolecular filter membrane, porous
Zeolite and clay etc..However, traditional oily waste treatment material often has a limitation of itself, for example separative efficiency is relatively low,
Substantial amounts of water, functional single, non-refractory can be also adsorbed while adsorbing greasy dirt and can not achieve remote control etc., this makes
It obtains these materials and is difficult to meet the needs of modern oily pollution process field.At present, the foamed material of various new functionalization by
It prepares and is applied to oil absorption, dream as usual clean et al. (preparation of magnetic response polyurethane sponge and oil absorbency research [J] chemical industry
New material, 2017 (2):Magnetic response polyurethane sponge 239-241.) is prepared for, but similar oily sorbing material is inflammable, once
It is ignited just easily triggering fire and causes secondary pollution.Therefore, be badly in need of development separative efficiency it is high, it is multi-functional, can realize remotely grasp
The material controlled and have good thermal stability is used for oily pollution process field.
Paper-like materials have a wide range of applications in every field such as industry, daily life and work.With science and technology and economy
Development, some paper with specific function come into being.Filter paper is commonly used a kind of spy in our daily lifes
Kind paper.Due to the use of conveniently, the features such as being easy to carry about with one, filter paper is favored in the fields such as daily water filtration and separation of solid and liquid.
At present, filter paper on the market is mostly prepared by plant fiber, and high temperature resistance is poor.Due to conventional filter paper to greasy dirt or
