Description
Affiliated technical field the present invention relates to a kind of amortizing packaging material and preparation method thereof, and particularly relating to a kind of is amortizing packaging material of raw material and preparation method thereof with leather and waste of flax
Background technology
At present, a large amount of packaging material that use mostly are foamed plastics such as EPS and EPE on the domestic and international market, these packings are big serious " white pollution " owing to its non-degradable brings, eliminate " white pollution ", seek new degradable packaging material, become a common research topic of countries in the world.
Since 1998, area such as Europe, the U.S., Japan, Korea S, Australia and the country industrial products of forbidding foam (EPS) packing of all making laws enter, improve perhaps that several times environmental protection tax limits and superseded bubble wrap material enters as packaged products, form so-called " Green Trade Barrier " according to the statistics made by the departments concerned, owing to there is not green package " passport ", the whole nation has 7,400,000,000 dollars commodity export to be obstructed every year, brings enormous economic loss to China.
Main substitute products are paper mould shockproof inner lining packing articles at present, its antidetonation impact resistance is significantly less than the EPS material, the impact resistance that resists into of these product goods mainly is that geometry by goods guarantees, owing to be subjected to the influence of mould structure and processing, the development of goods is subjected to very big restriction, can only make small-sized packaging cushion, still adopt the EPS foam plastic product and make the packaging cushion of large-scale household appliances and fill, this technical barrier rice so far can effectively be solved, from promoting Product Green environmental protection package image, reduce discarded object reclaiming utilization, avoid " green " consideration of trade barrier angle, research, exploitation, produce, promote and use " green package " material and goods, be the task of top priority, and had profound significance.
In addition, the subject matter that leather industry faced is the produced pollution and to the significant wastage of resource.In the process hides process, only there is the material of raw material tare weight 20% to be converted into the leather that can sell, remaining has all abandoned as discarded object.This has wasted good raw material skin resource on the one hand, also environment has been caused great harm on the other hand.It is reported that China produces 1,400,000 tons leather corner discarded object every year approximately, these solid waste are to cause one of with serious pollution key factor of leather industry.Since the eighties in 20th century, because the restriction of the environmental regulation of developed country's increasingly stringent, reduce gradually in the place that can be used for the landfill solid waste, pollution abatement costs is expensive day by day, developed country shifts its with serious pollution industry gradually to developing country, people have also actively developed the research and the application work of solid leather wastes resource.
China is process hides big country, particularly because China has the labour and the advanced advantages such as tanning technology of abundant raw material skin resource, cheapness, the machining center and the commerce trading center that have now developed into world's leather, though this provides opportunity for China's foreign exchange earning, has also brought serious pollution in leather industry simultaneously.According to incompletely statistics, leathers about 11,000,000,000 (standard of amounting to into is opened) such as China annual processing pig, ox, sheep, the leather corner scurf refuse amount of generation is huge.Therefore, make full use of leather resource, make the solid leather wastes resource, and do not exchange temporary transient economic development at the cost of the environment for, become severe challenge and inevitable choice that China's leather industry development faces.Sustainable development is wanted in Chinese leather industry, just must eliminate and pollute, and the comprehensive utilization of leather solid waste is exactly one of them aspect.Therefore, " tanning waste resource " become one of important topic of domestic and international concern.
