秸塑复合材料研究及其产业前景

Development and industry prospect of Straw-Plastic Composites

通过分析木塑复合材料的发展历程和产业现状,指出了当前"以秸代木"和"以秸代塑"的新需求。秸秆作为一种丰富的可再生生物质资源,具备开发为新型环保材料的潜力。本文创造性地提出了秸塑复合材料(Straw-Plastic Composites,SPC)的概念,剖析了秸秆生物质纤维的特性,秸秆中富含的生物基矿物质可能是秸塑作为新材料形成优于木塑材料的重要因素,同时阐述了秸塑产业发展的条件,指出了SPC是秸秆生物质全价工业化、高值化利用的典范,并提出现有条件下,在我国率先开发SPC的可行方案。

The history and industrial development of Wood-Plastic Composites (WPC) were analyzed, pointing out the present demands of"straw instead of wood"and"straw instead of plastic". Straw, as a kind of abundant renewable biomass resources, has the potential to be developed as a new environmentally friendly material. The concept of Straw- Plastic Composite (SPC) was creatively proposed in this paper. The characteristics of straw biomass fibers were dissected and the bio-based minerals in the straw may be one of the important factors, led to SPC is superior to WPC. Moreover, the conditions for the development of SPC were elaborated, which pointed out SPC is a typical model for the full-price and high-value industrialization of straw biomass. The feasible solution that pioneered the development of SPC has been put forward under the existing conditions in the country.
