Process for production of wood-plastic combinations by high energy electron accelerator

摘要

Production of wood-plastic combinations comprises impregnation using a polymerizable mixture, curing by electron beam irradiation and post-treatment by heating for 5 hours to 10 days at 20-100 degrees C. A process for the production of wood-plastic combinations is claimed in which wood or a component that contains wood in brought into at least partial contact with an impregnating mixture that contains a polymerizable component. The mixture is cured by polymerization in the presence of radical initiators and/or antioxidants by electron bean radiation having an energy of 0.2-15 MeV. The impregnating mixture comprises 100 pts.wt. of a mixture of (A) 50-100 wt.% (meth)acrylate (B) 0-50 wt.% comonomers and (C) 0-50 wt.% polymer that is soluble in (A) or (B), 0.001-5 pts.wt. radical initiator and/or antioxidant and 0-20 pts.wt. conventional processing additives. The irradiated product is post-heated at 20-100 degrees C for 5 hours to 10 days.
