摘  要：
通过热压聚合方法,利用苯乙烯和甲基丙烯酸甲酯对杨木进行强化试验,结果表明:聚合温度是主要影响因素,而聚合时间和引发剂、促聚剂的添加数量等因素是次要影响因素;聚合温度x与单体转化率y高度线性相关,线性回归方程为y=0.107x-0.036 7;最优制备工艺为:聚合温度80℃,聚合时间6h,环烷酸钴、氯化锌以及引发剂AIBN所占混合树脂掖比分别为2%、6%、3%;最大转化率为64.50%。傅立叶变换红外光谱分析结果表明,强化杨木单板中含有大量的苯环聚合物,羰基官能团大量增加。

摘  要：
A technique for enhancing the poplar veneer was studied in this paper.The results from the experiment of poplar veneer enhancing with styrene and methyl methacrylate by hot-pressing polymerization method showed that: the temperature for polymerization was the most critical factor,and the period and amount of initiator and aggregation promoting agents were also critical factors.The temperature for polymerization(x) was linearly correlated with the monomer conversion(y),and the equation was y=0.107x-0.036 7.The optimal technological process was: 80℃ for polymerization for 6 hours,the percentage of cobalt naphthenate,zinc chloride and AIBN initiator were 2%、6%、3%.The largest conversion was 64.5%.The analysis of fourier transform infrared spectroscopy showed that there large amount of benzene ring polymer in the enhanced poplar veneer,and the carbonyl-group remarkably increased.
