以杨木单板和秸秆板为原材料,采用自主研制的无机胶黏剂作为粘结剂制备地板用双秸秆板芯层复合结构材。探索了涂胶量、热压温度、热压时间和热压压力对复合结构材物理力学性能的影响规律,并通过正交试验法进行了工艺优化。结果表明,当涂胶量为300 g/m2、热压温度120 ℃、热压时间15 min、热压压力1.5 MPa时,复合结构材的静曲强度、弹性模量、表面结合强度、Ⅲ类和Ⅱ类浸渍剥离性能均远远优于GB/T 18103-2000《实木复合地板》和GB/T 15104-2006《装饰单板贴面人造板》规定的指标要求;正交试验得到复合结构材物理力学性能最优的工艺参数为涂胶量为300 g/m2、热压温度为120 ℃、热压时间为18 min、...

double straw board core layer composite structure material used for floor was prepared with poplar veneer and straw board as raw materials, and independent research and development of inorganic adhesive as binder. The effect of glue-spread content, hot pressing temperature, hot pressing time and pressure on the properties of composite structure material was studied, and the orthogonal experimental method was used for process optimization. Results show that when 300 g/m2 of glue-spread content, 120℃ of hot pressing temperature, 15 min of hot pr...
