如今生物降解材料隨著人類保護環(huán)境意識的提高，石油資源的不斷減少，生物降解聚合物取代傳統(tǒng)石油基聚合物已經(jīng)成為發(fā)展的趨勢。那么生物降解顆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屬于熱塑性生物降解塑料，是己二酸丁二醇酯和對苯二甲酸丁二醇酯的共聚物，兼具PBA和PBT的特性，既有較好的延展性和斷裂伸長率，也有較好的耐熱性和沖擊性能；此外，還具有優(yōu)良的生物降解性，是生物降解塑料研究中非常活躍和市場應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.

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;

在很佳條件下所制得的SPI可生物降解材料的拉伸強度為8.61MPa，斷裂伸長率為196.78%，吸水率為31.6%。政府有望出臺相應的優(yōu)惠政策、法律法規(guī)鼓勵市場應用，生物降解材料大規(guī)模應用前景樂觀。接下來我們來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過生物技術(shù)制成的高分子材料，如多羥基脂肪酸酯(PHA)和其他通過生物技術(shù)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.

淀粉基生物降解塑料是將淀粉與其他聚合物經(jīng)改性和支化反應后混合而成的塑料制品。它們可用作包裝材料、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.

而不是工業(yè)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、無刺激、高強度、易加工和良好的生物相容性等特點。產(chǎn)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是實現(xiàn)生態(tài)和經(jīng)濟雙重效果的生物環(huán)保材料，是近年來很活躍、發(fā)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縮合成的，是公認的綜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.
