摘　　要：采用乙二醇和丙烯酰胺来改性三聚氰胺树脂,制备低分子树脂浸渍重组竹,从而来减少重组竹表面开裂。结果表明,当丙烯酰胺的加入量为树脂质量的6%,乙二醇与甲醛的摩尔比为1.5:1时,能够有效地降低重组竹表面的开裂情况。黏度越低,树脂对重组竹表面的润湿性越好,接触角越小,浸润速度越快。In order to decrease the surface crack of reconstituted bamboo,glycol and acrylamide were used to modify the melamine resin for bamboo impregnation.The results showed that when the weight of acrylamide was added to 6％ of the resin and the mole ratio of glycol to formaldehyde was 1.5：1,the crack of reconstituted bamboo decreased.The lower viscosity of resin,the better its wettability on the surface of material to be impregnated,that resulted to small contact angle and faster impregnation speed.
