摘　　要：以废棉和木屑为原料,在18%的碱及系列助剂作用下水解成碱纤维素。然后用环氧树脂进行接枝,摩尔投料比环氧树脂与碱纤维为0.5∶1.0,反应温度100℃,反应时间5.0h,催化剂用量1%,醚化接枝率为32%。所得环氧纤维素醚(Cel-Ep)以0.6mol的Cel-Ep与0.4mol的CAB(celluloseacetate-butyrate)共混,合成出一种性能良好的新涂料产品。用IR对产品结构进行了确认。The alkali cellulose was obtained by treatment of waste cotton,cotton linters or wood scraps for 10 min at 25℃ with twice their weight of NaOH as a 18% solution.The product was filtered,grafted and etherified with epoxy resin,alcohol and catalyst.The yield of alkali cellulose grafted and etherified ,which is known as Cel-Ep,was up to 32%,when mole ratio of alkali cellulose and epoxy is 2 at 100 ℃ for 5.0 hour and the amount of catalyst is 1%. A newly good coating material was synthesized with 0.6 moles Cel-Ep and 0.4 moles cellulose acetate-butyrate(CAB) mixture,its structure was characterized by IR.
