化石基生物降解塑料:主导产品为PBAT与PBS石油基生物降解塑料是指以石化产业链中所出产的单体经过聚合所制造的可生物降解塑料。这类塑料现在主要包括聚丁二酸丁二醇酯(PBS)/聚丁二酸-己二酸丁二醇酯(PBSA),聚已内酯(PCL)和聚丁二醇丁二酸-对苯二酸盐(PBAT)等。

Fossil-based biodegradable plastics: PBAT and PBS petroleum-based biodegradable plastics are biodegradable plastics produced by polymerization of monomers produced in the petrochemical industry chain. These plastics mainly include polybutylene succinate (PBS)/polybutylene succinate-adipate (PBSA), polycaprolactone (PCL) and polybutylene succinate-terephthalate (PBAT).
1.聚ε-己内酯(PCL)
1. Poly (epsilon-caprolactone) (PCL)
聚ε-己内酯(PCL)是由ε-己内酯经开环聚合得到的低熔点聚合物,其熔点仅62℃。PCL的降解性研究从1976年就已开端,在厌氧和需氧的环境中,PCL都可以被微生物彻底分解。
Poly (epsilon-caprolactone) (PCL) is a low melting point polymer obtained by ring-opening polymerization of epsilon-caprolactone. Its melting point is only 62 C. The degradation of PCL has been studied since 1976. In anaerobic and aerobic environments, PCL can be completely decomposed by microorganisms.
与PLA相比,PCL具有更好的疏水性,但降解速度较慢;一起其合成工艺简略、本钱较低。PCL的加工功能,可用普通的塑料加工设备制成薄膜及其它制品。
Compared with PLA, PCL has better hydrophobicity, but its degradation rate is slower; together, its synthesis process is simple and its cost is lower. PCL has excellent processing function. It can be made into film and other products by ordinary plastic processing equipment.
一起,PCL和多种聚合物具有很好的相容性,如PE、PP、PVA、ABS、橡胶、纤维素及淀粉等,经过共混,以及共聚可得到功能的资料。尤其是其与淀粉的共混或共聚,既可保持其生物降解性,又可下降本钱,因而深受注视。
Together, PCL and a variety of polymers have good compatibility, such as PE, PP, PVA, ABS, rubber, cellulose and starch. Through blending and copolymerization, excellent information can be obtained. Especially its blending or copolymerization with starch can not only maintain its biodegradability, but also reduce its cost, so it has attracted much attention.
PCL与淀粉共混可得到耐水性好的降解塑料,其价格与纸张附近;使用原位聚合办法,可将ε-己内酯与淀粉接枝,得到功能的热塑性聚合物。
PCL can be blended with starch to obtain degradable plastics with good water resistance, and its price is near the paper. In situ polymerization method can be used to graft epsilon-caprolactone with starch to obtain thermoplastic polymers with excellent functions.
2.聚酯类--PBS/PBSA
2. Polyesters--PBS/PBSA
与同类产品比较,聚酯生物分降塑料的长处:
Compared with similar products, the advantages of polyester biodegradable plastics are as follows:
1)上述生物分降塑料(聚乳酸、聚ε-己内酯、聚羟基烷基酸酯)的致命缺点之一就是耐热性差,这影响了它在餐饮范畴的使用推广。
1) One of the fatal shortcomings of the above-mentioned biodegradable plastics (polylactic acid, poly-epsilon-caprolactone, polyhydroxyalkyl ester) is its poor heat resistance, which affects its application and promotion in catering field.
2)上述生物分降塑料(聚乳酸、聚ε-己内酯、聚羟基烷基酸酯)加工工艺条件苛刻,产业化上存在一些无法的困难。
2) The processing conditions of the above-mentioned biodegradable plastics (polylactic acid, poly-epsilon-caprolactone, polyhydroxyalkyl ester) are harsh, and there are some difficulties in industrialization.
3)聚乳酸是水降解生物塑料,保存过程中不能承受水分子,在普通贮存和正常使用过程中功能无法得到保证。
3) Polylactic acid (PLA) is a water-degradable bioplastics. It can not withstand water molecules during storage, and its function can not be guaranteed during general storage and normal use.
