摘　　要：以杉木机床刨花、42.5#普通硅酸盐水泥为主要原料,Na2SiO3、CaCl2、Na2SiO3+CaCl2快速固化添加剂,在热压温度100℃、热压时间15min、热压压力3MPa的条件下,研究了灰木比、快速固化添加剂对快速固化水泥刨花板的性能和回弹特性的影响。结果表明,灰木比、添加剂的种类对水泥刨花板的静曲强度(MOR)、弹性模量(MOE)、平面抗拉强度、回弹率和吸水厚度膨胀率都有显著的影响。Study on effect of cement/wood ratio and quick curing additive on properties and resilience of cement bounded particle board was under the conditions as follows: Chinese fir particle, 42.5# cement, Na2SiO3、CaCl2、 Na2SiO3+CaCl2 as additive at 100℃ pressure in 15 minutes with 3Mpa. The result showed that cement/wood ratio and additive had evident effect on MOR, MOE, strength of extension, resilience rate and thickness expansion of cement bounded particle board.
