摘要

以60Co为源，在3mrad下，研究了添加剂对单体甲基丙烯酸丁酯(BA)接枝到simul(一种软木材)的影响。在酸和尿素的存在下，将微量(1%)的低聚物(EA、PEA和UA)和多官能团单体(TMPTA、TPGDA和NVP)加入到simul + BA体系中，进一步增强了聚合物负载(接枝)。酸加的增效产率使木塑的TS值显著降低;但尿素能协同提高这些系统的PL和TS值。

Effect of urea on the mechanical strength of wood-plastic composites

The effect of additives on the grafting of a monomer, butylmethacrylate (BA), into simul (a soft wood) has been studied using ⁶⁰Co source at 3 Mrad. The enhancement of polymer loading (grafting) by the addition of minute amounts (1%) of oligomers (EA, PEA and UA) and of polyfunctional monomers (TMPTA, TPGDA and NVP) into simul + BA system has been further increased in the presence of acid and urea. The synergistic PL yields by acid addition cause substantial decrease of TS values of WPC; but urea increases both PL and TS values synergistically in these systems.
