非结构用臭冷杉集成材的性能研究

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。

Set Properties of Material with Non Structure of Abies Nephrolepis

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.
