摘要 以常见的几种无机盐作添加物加到粗纤维中配制成粗纤维复合材料,经高温、高压处理加工制成了可降解塑料制品. 测定了其在模具中的上升高度及抗拉强度. 在处理过程中发现能产生氨的弱酸铵盐水溶液,具有很强的破坏纤维素有规结构的能力,可增加其塑性,制品的抗拉强度相当或优于常见的两种树脂制品的抗拉强度. Crude cellulose composite was prepared by adding commonly-used inorganic salts in crude cellulose and pr℃essed into cellulose-based degradable plastics at the conditions of high temperature and high pressure. Rising height and tensile strength of the plastics were determined in a mould. The experiments proved that ammonium salts of weak acids that can be decomposed into ammonia had a strong ability to break up well-ordered structure of cellulose in the course of pr℃essing and enhance its plasticity. The tensile strength of products sample was equal to or superior to those of two often-used resins.
