随着能源提价以及环境问题的日益凸显,范围内可降解生物资料替代传统石油产品的脚步呈现出逐渐加速的趋势,预计还将出台相应的优惠政策和法律法规,鼓舞市场应用,生物降解资料的大规模应用远景达观。

With the increase of energy prices and the increasingly prominent environmental problems, the pace of biodegradable materials replacing traditional petroleum products has been accelerating in the international arena. It is expected that the government will also promulgate relevant preferential policies, laws and regulations to encourage market applications and achieve a long-term vision for the large-scale application of biodegradable materials.
生物降解资料包含用生物技术直接制取的高分子资料,如聚羟基脂肪酸酯(PHA)等;用生物技术制取的质料再经聚合得到的一类资料,如聚乳酸(PLA)、聚丁二酸丁二醇酯(PBS)、聚氨基酸等;此外还有淀粉基生物降解塑料、二氧化碳共聚物脂肪族聚碳酸酯(APC)等。
Biodegradable materials include macromolecule materials directly prepared by biotechnology, such as polyhydroxyalkyl fatty acid ester (PHA), polylactic acid (PLA), polybutylene succinate (PBS), polyamino acid and so on, and starch-based biodegradable plastics, carbon dioxide copolymer aliphatic polycarbonate (APC). And so on.
淀粉基生物降解塑料,是淀粉经过改性、接枝反应后与其他聚合物共混加工而成的一种塑料产品,在工业上能够替代一般通用塑料等,能够用作包装资料,防震资料,地膜,食品容器,玩具等。
Starch-based biodegradable plastics is a kind of plastics product made by blending starch with other polymers after modification and grafting reaction. It can replace general plastics in industry, and can be used as packaging materials, shock-proof materials, plastic film, food containers, toys and so on.
PLA是以乳酸为质料聚合生成的高分子资料,具有无毒、无刺激性、强度高、易加工成型和优良的生物相容性等特点,制品在使用后可完全降解,因此,PLA是一种能真正达到生态和经济两层效应的生物环保资料,是近年来开发研究比较活泼、发展比较快的生物降解塑料。
PLA is a kind of macromolecule material produced by the polymerization of lactic acid. It has the characteristics of non-toxicity, non-irritation, high strength, easy processing and good biocompatibility. The products can be completely degraded after use. Therefore, PLA is a kind of bio-environmental protection material that can truly achieve the ecological and economic effects. It is the most active and fastest-growing biodegradable plastics in recent years.
聚丁二酸丁二醇酯由丁二酸和丁二醇经缩聚而得,是现在公认的归纳功能比较好的生物降解塑料。因为PBS归纳功能优异,性价比合理,用处极为广泛,可用于包装、餐具、化妆品瓶及药品瓶、一次性用品、农用薄膜、农药及化肥缓释资料、生物医用高分子资料等领域。
Polybutylene succinate is obtained by condensation of succinic acid and butylene glycol. It is now recognized as the best biodegradable plastic with inductive function in the world. Because of its excellent inductive function, reasonable cost performance and wide application, PBS can be used in packaging, tableware, cosmetics bottles and drug bottles, disposable medical supplies, agricultural films, slow-release materials of pesticides and fertilizers, biomedical polymer materials and other fields.
聚羟基脂肪酸酯属于天然高分子聚酯,是很多细菌在特定条件下组成的一种细胞内聚酯。已有超越90个属的细菌被发现能够组成超越150种以上不同结构的PHA。现在现已商品化的PHA产品主要有聚羟基丁酸(PHB)、羟基丁酸与羟基戊酸的共聚物(PHBV)和羟基丁酸与羟基己酸的共聚物(PHBHHx)。
Polyhydroxyalkanoate is a kind of natural macromolecule polyester. It is a kind of intracellular polyester composed of many bacteria under specific conditions. More than 90 genera of bacteria have been found to form PHA with more than 150 different structures. At present, the commercialized PHA products mainly include Polyhydroxybutyric acid (PHB), copolymer of hydroxybutyric acid and hydroxy valeric acid (PHBV) and copolymer of hydroxybutyric acid and hydroxy hexanoic acid (PHBHx).
