摘要 使用常温快速固化的改性醋酸乙烯作为集成材胶黏剂。并通过设计正交试验,通过改变不同压力、时间、固化剂用量三因素制作出9组试件,经测定其压缩剪切强度,并分析得出对长白山臭冷杉结构集成材的压剪强度影响主次关系为:时间﹥MDI用量﹥压力。实验表明,臭冷杉结构集成材的最佳工艺条件为时间为2h,压力为3MPa,MDI用量为20%。该条件下制备的集成材具有良好的胶接性和耐水性,符合国标对结构集成材的要求。 Consider using the normal temperature of the modified fast-curing vinyl acetate as integrated timber adhesive. And through orthogonal experiment design, through the change different pressure, time, curing agent dosage three factors make 9 groups specimens, the determination of the compression shear strength, and analysis of smelly loose structure integrated timber press shear strength of influence for primary and secondary relations: time MDI dosage pressure. Experiments show that, smelly loose structure integrated timber the optimum technological conditions for time is 2 h, pressure for 3 MPa, amount to 20% MDI. The conditions of the preparation of integrated timber has good glue meet sex and water resistance, reach national structure of the integrated timber requirements.
