摘要: 近年来,随着石油资源的日渐短缺以及对材料可持续发展的战略要求,以纤维素、壳聚糖等为代表的可降解生物材料,其大分子具有多羟基结构,在燃烧时具有较高的成炭率,因此利用阻燃改性的生物基材料替代石油基阻燃剂和炭源具有潜在的发展前景。主要介绍了多糖类生物材料在阻燃方面的化学改性或物理复合方法,通过对纤维素、壳聚糖、淀粉、海藻酸盐和环糊精等生物材料的阻燃改性,以赋予改性材料较高的阻燃性和成炭效率。

Abstract: In recent years, with the increasing shortage of petrochemical resources and the strategic requirements for the sustainable development of materials, biodegradable biomaterials such as cellulose and chitosan have high char residue yield during combustion because of their polyhydroxyl structure. Therefore, there is a potential development prospect to use biobased flame retardants and charforming agents as alternative to petroleumbased flame retardants and carbon sources. This paper mainly introduces the chemical modification and physical blending composite methods of polysaccharide biomaterials, such as the flame retarded modification of cellulose, chitosan, starch, lignin, alginate and cyclodextrin, in order to endow the modified biomaterials with higher flame retardancy and charring efficiency.
Key words: biobased material; charring; flame retardant modification
