如今生物降解材料随着人类保护环境意识的提高,石油资源的不断减少,生物降解聚合物取代传统石油基聚合物已经成为发展的趋势。那么生物降解颗粒降解材料您知道哪些?
Nowadays, with the improvement of human awareness of environmental protection and the continuous reduction of petroleum resources, biodegradable polymers have become a development trend to replace traditional petroleum based polymers. What do you know about biodegradable particulate degradable materials?
pbat属于热塑性生物降解塑料,是己二酸丁二醇酯和对苯二甲酸丁二醇酯的共聚物,兼具PBA和PBT的特性,既有较好的延展性和断裂伸长率,也有较好的耐热性和冲击性能;此外,还具有优良的生物降解性,是生物降解塑料研究中非常活跃和市场应用很好降解材料之一。
As a thermoplastic biodegradable plastic, pbat is a copolymer of butylene adipate and butylene terephthalate. It has the characteristics of both PBA and PBT. It has good ductility and elongation at break, as well as good heat resistance and impact performance; In addition, it also has excellent biodegradability, and is one of the very active biodegradable materials in the research and market application of biodegradable plastics.
生物降解颗粒抗水性能的影响规律,得出制备SPI可生物降解材料的很佳改性工艺条件为:SPI与四氢呋喃的质量体积比为1:3,并采用正交组合试验设计优化了SPI可生物降解材料的改性条件;
The influence rule of the water resistance of biodegradable particles shows that the best modification conditions for preparing SPI biodegradable materials are as follows: the mass volume ratio of SPI to tetrahydrofuran is 1:3, and the modification conditions of SPI biodegradable materials are optimized by orthogonal combination test design;
在很佳条件下所制得的SPI可生物降解材料的拉伸强度为8.61MPa,断裂伸长率为196.78%,吸水率为31.6%。政府有望出台相应的优惠政策、法律法规鼓励市场应用,生物降解材料大规模应用前景乐观。接下来我们来看看生物降解材料中包含哪些材料。
Under good conditions, the tensile strength of SPI biodegradable material is 8.61MPa, the elongation at break is 196.78%, and the water absorption is 31.6%. The government is expected to introduce corresponding preferential policies, laws and regulations to encourage market application, and the prospect of large-scale application of biodegradable materials is optimistic. Next, let's look at which materials are included in biodegradable materials.
可生物降解材料包括直接通过生物技术制成的高分子材料,如多羟基脂肪酸酯(PHA)和其他通过生物技术制成的原材料,如聚乳酸(PLA)、聚丁二酸丁二醇酯(PBS)、聚氨基酸、淀粉基可生物降解塑料、二氧化碳共聚物脂肪族聚碳酸酯(APC)等。
Biodegradable materials include polymer materials directly made by biotechnology, such as polyhydroxy fatty acid ester (PHA) and other raw materials made by biotechnology, such as polylactic acid (PLA), polybutylene succinate (PBS), polyamino acids, starch based biodegradable plastics, carbon dioxide copolymer aliphatic polycarbonate (APC), etc.
生物降解颗粒
淀粉基生物降解塑料是将淀粉与其他聚合物经改性和支化反应后混合而成的塑料制品。它们可用作包装材料、防震材料、薄膜、食品容器、玩具等。
Starch based biodegradable plastic is a kind of plastic product made by mixing starch and other polymers after modification and branching reaction. They can be used as packaging materials, shockproof materials, films, food containers, toys, etc.
而不是工业上的普通塑料。聚乳酸(PLA)是由乳酸聚合而成的高分子材料,具有无毒、无刺激、高强度、易加工和良好的生物相容性等特点。产品使用后可完全分解。
It is not ordinary plastic in industry. Polylactic acid (PLA) is a polymer material polymerized from lactic acid, which has the characteristics of non-toxic, non irritating, high strength, easy processing and good biocompatibility. The product can be completely disassembled after use.
因此,PLA是实现生态和经济双重效果的生物环保材料,是近年来很活跃、发展很快的生物降解塑料。聚丁二酸丁二醇酯是由丁二酸和丁二醇缩合成的,是公认的综合性能很好的可生物降解塑料。
Therefore, PLA is a bio environmental protection material that achieves both ecological and economic effects. It is a very active and rapidly developing biodegradable plastic in recent years. Polybutylene succinate (PBS) is a kind of biodegradable plastic with good comprehensive properties, which is synthesized by condensation of succinic acid and butanediol.
