Abstract
The invention discloses a completely biodegradable material for cards, which comprises the following components in percentage by weight: 50 to 99 percent of polyhydroxyalkanoate, 0 to 50 percent of modifier, 0 to 40 percent of filler and 0 to 10.5 percent of other assistants. In the invention, the polyhydroxyalkanoate is modified by combining the proper modifier and other assistants, so the performance of the polyhydroxyalkanoate is improved to meet the use performance requirements of cards; and the material can be processed and produced by conventional equipment.
Description
Technical field
The invention belongs to the material field, particularly a kind of card Biodegradable Materials.
Background technology
Along with rapid development of economy, the handling problem of a lot of industrial refuses is serious day by day, is not only increasing the weight of the burden of the earth, also is very serious to pollution, the harm of physical environment.Along with finance, development of urbanization, being stuck in people's life has become indispensable thing, and along with the increase gradually of issued volume, the card that goes out of use is also more and more.
Liu Tong card such as bank card, mobile telephone card, other various IC-cards or the like mainly are to utilize conventional plastic to generate in the market, as PET (polyethylene terephthalate), PVC (polyvinyl chloride), PP (polypropylene), PS (polystyrene) or the like petroleum base material, these material non-degradables, be not easy to reclaim again and utilize, destroy and pollution if untimely recovery will produce environment.But, be difficult to accomplish comprehensive recovery from the angle of recycling because single card sheet volume and weight is all smaller.From the angle that increases the service life, the frequency of weeding out the old and bring forth the new and the abandoning increase along with card also is difficult to realize life-time service, and therefore selecting degradable base material is to solve card to pollute best choice.
Commercial at present biodegradable material has PLA (poly(lactic acid)), PHA (PHA), PBS (poly butylene succinate), PPC (polycarbonate) and some other Biodegradable materials, but the performance of these materials all can not meet the performance requriements of producing this card fully.What have is softer, and what have is too crisp, and the not heatproof and the surface hardness that have all do not reach standard-required, and has defectives such as easy scuffing.Need carry out modification to above-mentioned materials, but still not have relevant open source literature at present.
Summary of the invention
The present invention is for overcoming above-mentioned technological deficiency, discloses a kind of well behaved, processing characteristics and stablized the card Biodegradable Materials.
