生物降解塑料的原材料有哪些

根据原材料的不同，常见的生物降解塑料少有几种，下面生物降解颗粒生产厂家来给大家讲讲相关内容。

According to different raw materials, there are at least several kinds of common biodegradable plastics. The manufacturers of biodegradable granules will tell you about them.

聚己内酯（PCL）

Polycaprolactone (PCL)

这种塑料具有良好的生物降解性，熔点是62℃。分解它的微生物广泛地分布在喜气或厌气条件下。作为可生物降解材料可把它与淀粉、纤维素类的材料混合在一起，或与乳酸聚合使用。

This kind of plastic has good biodegradability, and its melting point is 62 ℃. The microorganisms that break it down are widely distributed in the pleasant or unpleasant conditions. As a biodegradable material, it can be mixed with starch and cellulose materials or polymerized with lactic acid.

聚丁二酸丁二醇酯（PBS）及其共聚物

Polybutylene succinate (PBS) and its copolymer

以PBS（熔点为114℃）为基础材料制造各种高分子量聚酯的技术已经达到工业化生产水平。

The technology of manufacturing various high molecular weight polyester based on PBS (melting point 114 ℃) has reached the level of industrial production.

聚乳酸（PLA）

Polylactic acid (PLA)

美国Natureworks公司在完善聚乳酸生产工艺方面做了积极有效的工作，开发了将玉米中的葡萄糖发酵制取聚乳酸，年生产能力已达1.4万吨。日本UNITIKA公司，研发和生产了许多种制品，其中帆布、托盘、餐具等在日本爱知世博会被广泛使用。

Natureworks of the United States has made active and effective work in improving the production process of polylactic acid, and has developed the production of polylactic acid by fermenting the glucose in corn, with an annual production capacity of 14000 tons. Japan UNITIKA Company has developed and produced many kinds of products, among which canvas, tray, tableware, etc. are widely used in Aichi World Expo.

聚羟基烷酸酯(PHA)

Polyhydroxyalkanoate (PHA)

利用可再生资源得到的生物降解塑料，把脂肪族聚酯和淀粉混合在一起，生产可降解性塑料的技术也已经研究成功。在欧美，淀粉和脂肪族聚酯的共混物被广泛用来生产垃圾袋等产品。上规模大、销售好的是意大利的Novamont公司，其商品名为Mater-bi，公司的产品在欧洲和美国有较大量的应用。

Biodegradable plastics made from renewable resources, which mix aliphatic polyester and starch together to produce degradable plastics, have also been successfully studied. In Europe and America, the blend of starch and aliphatic polyester is widely used to produce garbage bags and other products. Novamont, an Italian company with a large scale and good sales in the world, whose trade name is Mater bi, has a large number of applications in Europe and the United States.

德国BASF公司所制造的脂肪族芳香族无规共聚酯（Ecoflex），其单体为：己二酸、对苯二甲酸、1,4-丁二醇。生产能力在14万吨/年。同时开发了以聚酯和淀粉为主的生物降解塑料制品。

Aliphatic aromatic random copolyester (Ecoflex) manufactured by German BASF company, its monomer is adipic acid, terephthalic acid and 1,4-butanediol. The production capacity is 140000 tons/year. At the same time, biodegradable plastic products based on polyester and starch were developed.

聚乙烯醇（PVA）类生物降解塑料

Polyvinyl alcohol (PVA) biodegradable plastics

如意大利NOVMANT的MaterBi产品在上世纪90年代主要是在淀粉中加入PVA，它能吹膜，也能加工其它产品。聚乙烯醇类材料，需要经过一定的改性后方具有良好的生物降解性能，北京工商大学轻工业塑料加工应用研究所在这方面取得了一定成果。

For example, in the 1990s, the MaterBi product of NOVMANT in Italy mainly added PVA to starch, which can blow film and process other products. Polyvinyl alcohol materials need to be modified to have good biodegradability. The Institute of Light Industrial Plastics Processing and Application of Beijing Technology and Business University has made some achievements in this regard.

二氧化碳共聚物

Carbon dioxide copolymer

国外，较早研究二氧化碳共聚物的主要为日本和美国，但一直没有工业化生产。国内内蒙古蒙西集团公司采用长春应用化学研究所的技术，已建成年产3000吨二氧化碳/环氧化合物共聚物树脂的装置，产品主要应用在包装和医用材料上。

In foreign countries, Japan and the United States were the first countries to study carbon dioxide copolymers, but there has been no industrial production. Inner Mongolia Mengxi Group Co., Ltd. has adopted the technology of Changchun Institute of Applied Chemistry to build a device that can produce 3000 tons of carbon dioxide/epoxy copolymer resin per year. The products are mainly used in packaging and medical materials.

中科院广州化学研究所陈立班博士开发的低分子量二氧化碳共聚物技术已在江苏泰兴开始投产，品种是低相对分子质量二氧化碳/环氧化合物共聚物，用来作为聚氨酯发泡材料的原材料，用于家用电器等的包装。等等。

The low molecular weight carbon dioxide copolymer technology developed by Dr. Chen Liban of the Guangzhou Institute of Chemistry of the Chinese Academy of Sciences has been put into production in Taixing, Jiangsu Province. The variety is low relative molecular weight carbon dioxide/epoxy compound copolymer, which is used as the raw material of polyurethane foam materials and packaging for household appliances. wait.
