摘要:

目的开发一种环境友好的可降解生物质包装材料，旨在推进绿色物流发展和环境保护。方法采用生物原位成型技术一步成型制得全降解生物质包装填充材料ECO生物质板。并对其防水性能、动态缓冲性能、阻燃性能、生物降解性进行测定。结果 ECO生物质板的接触角为104.2°，缓冲系数C均大于3.0，氧指数>35，样品在埋土20 d后出现了部分破损，50 d后降解成小碎片和粉状。结论利用秸秆等农林废弃物制备的ECO生物质板具有较好的缓冲性能，可以防水阻燃，并且易于生物降解。与其他可降解材料相比，具有价格低廉、可推广性强等优点，有巨大的市场竞争力，是一种具有广泛应用前景的新型缓冲包装材料。

Abstract:

The paper aims to develop an environmentally friendly biodegradable packaging material to promote green logistics and environmental protection. ECO biomass plate, a fully degradable biomass packaging filling material, was prepared by one-step in-situ molding technology. Its waterproofing, dynamic buffering, flame retardant and biodegradability were tested. The contact angle of ECO biomass plate was 104.2°; the buffer coefficient C was greater than 3.0; the oxygen index OI was more than 35. The samples were partially damaged after 20 days of burial, and degraded into small fragments and powders after 50 days. ECO biomass board prepared from agricultural and forestry wastes such as straw has good cushioning performance, can be waterproof and flame retardant, and is easy to be biodegraded. Compared with other degradable materials, it is a new type of cushioning packaging material with broad application prospects because of its low price, strong popularization and huge market competitiveness.

Key words: biodegradable biomass plate biological in situ molding packaging material
