Description
Technical field
The present invention relates to a kind of preparation method of matrix material.
Background technology
Along with the attention of people to environment, the development and use of environmentally friendly material progressively become the focus that common people pay close attention to.Utilize the depleted resource to prepare high performance novel material, gradually reduce the consumption of Nonrenewable resources, environment is significant for preserving our planet.
In recent years, because world's paper and cardboard consumption constantly increase, the generation of waste paper also constantly increases.Along with people's environmental consciousness constantly strengthens, waste paper utilizes day by day and comes into one's own.Waste paper is the secondary vegetable fibre of reuse, has the series of advantages of vegetable fibre: cheap, density is little, has higher modulus of elasticity, and is close with inorganic fibre, and its biological degradability and recyclability are the most outstanding advantages.The countries in the world waste paper rate of recovery generally rises at present, and the waste paper rate of recovery of Korea S, Germany has reached 75%.It mainly is used to matrix material, functional materials, wrapping material.Be mainly used in preparation thermoplastic polymer matrix material, cement-base composite material, Biodegradable resin matrix material at field of compound material waste paper, but when other matrix materials of preparation, study lessly relatively.Simultaneously considerable progress has been obtained about the research of waste paper reutilization technology in countries in the world, but product the research aspect the reliability is also seldom in environment for use.
China is a tanning industry big country, traditional tanning industry causes a large amount of losses of Animal resources, contain 30% protein approximately in the solid waste that cutting and cutting produce after the tanning, China produces more than 140 ten thousand tons of such leather solid waste every year approximately, if contain more than 50 ten thousand tons of cadmium solid waste. these solid waste reasonably can not be handled, not only can serious environment pollution, and can cause a large amount of losses of collagen protein.Collagen protein is precious recycling natural resources, also is one of green resource few in number simultaneously.At present, collagen widespread use in fields such as foodstuffs industry, biological medicine, nutritive health-care.But it is poor that collagen has physical and mechanical properties as natural materials, biodegradable, and the general relatively poor characteristics of synthetic materials stable mechanical property but biocompatibility.Therefore, preparation collagen-polymer composite makes its common advantage that has two kinds of materials simultaneously, will have development prospect widely.
According to the characteristics that waste paper fibre and collagen protein self have, these two kinds of materials are carried out the compound higher and degradable composite material of a kind of intensity that is expected to obtain, it can be used in wrapped pad barrier material field.The present invention is the feedstock production degradable composite material with two kinds of wastes, has both alleviated environmental stress, has opened up new road for waste utilizes again again.
Summary of the invention
The objective of the invention is provides a kind of preparation method with waste paper fibre and discarded leather collagen synthetic composite material in order to solve the noxious waste pollution environment that cutting and cutting produce after the tanning, the problem that causes the collagen protein loss.
The present invention is as follows with the preparation method of waste paper fibre and discarded leather collagen synthetic composite material: one, the deinking of waste paper fibre is handled: with NaOH, H
2O
2, Na
