摘　　要：脲醛树脂中加入其质量的15%的氧化淀粉共混反应,制备成氧化淀粉改性脲醛树脂。该样品为白色膏状物质,含固量为30.55%,游离甲醛值为0.07%,贮存稳定。用其复鞣填充的坯革撕裂强度为2.48 N/mm,拉伸强度为14.4 0 MPa,断裂伸长率为161.06%,且饱满、富有弹性、黑色调饱满及粒面平整;耐热及耐折性能优良。Urea formaldehyde resin was modified with 15% oxidized starch. The sample, which contained 0. 07% formaldehyde, was white cream body and 30.55% solid content . The tear strength of the crust made by the sample was 2. 48 N/mm, the tensile strength was 14.4 0 MPa, the rate of extension at breaking was 161.06 percent; the crust was full, flexible, full black tone and smooth grain; in the same way, the crust owns fine aging resistance property of heat and folding.
