摘 要:随着木材资源的日趋紧张,秸秆板的制造和利用工作也在广泛发展,为降低稻草刨花板制造成本,研究了蓖麻油和桐油等添加剂替代部分异氰酸酯对稻草刨花板物理力学性能的影响,研究了竹刨花增强稻草刨花板和稻草刨花板的板坯含水率对于其物理力学性能的影响。结果表明:稻草刨花板制备中,采用2%的蓖麻油替代2%的异氰酸酯是完全可行的;在本试验范围内,竹刨花增加量需超过30%,才可起到真正增强的作用;板坯含水率在14%时,所制得的稻草刨花板整体性能较好。With the increasing shortage of wood resources,the work of making and using straw board is being well-developed.In order to decrease the production cost,castor oil and tung oil were used as part substitutes for isocyanatein during making straw board.The influences of the part substitution on the physical and mechanical properties of rice straw board were examined.The effects of moisture content of mats on the physical and mechanical properties of rice straw board reinforced with bamboo particle and rice-straw particleboard were also investigated.The test results showed that it was fairly feasible when the straw particleboard was produced by 2% castor oil as substitute for 2% ocyanate,and when the increasing amount of bamboo particle strengthened to more than 30%,the bamboo particle could really reinforce the properties of rice-straw particleboard,and when the moisture content of mat reached 14%,the integral performance of rice-straw particleboard was high.
