摘　　要：淀粉经氧化后再与尿素缩合改性,作为聚乙酸乙烯酯乳液的填充剂,制备一种胶合板用水性高分子-异氰酸酯胶(API)主剂。实验研究了氧化剂用量、改性淀粉填充量、聚乙烯醇用量以及异氰酸酯用量对胶合板湿强度的影响,确定了较佳的配比,制得了一种低成本、环保的API胶主剂。Starch oxidized and condensed with urea,then the modified oxidized starch was blend with polyvinyl acetate emulsion synthesized in laboratory to prepare a main agent of aqueous polymer isocyanate （API）adhesive for plywood.The effects of the content of oxidant and the amount of modified starch,polyvinyl alcohol and isocyanate on green strength of plywood were experimentally studied and the more optimal composition was obtained.The new main agent of API has excellent economic profit and no pollution.
