ABSTRACT:
The method of making a pressible mixture of lignocellulose-containing fibers and a thermoplastic material includes mixing the fibers with 2 to 8% by weight of a duroplastic, preferably an aminoplast or a phenoplast, 0.5 to 2% by weight of a hydrophobic agent for example, paraffin, and 2 to 10% by weight of an aqueous dispersion of methacrylate and/or polyethylene to form a pretreated fiber mixture and then subsequently mixing 100 parts by weight of the pretreated fiber mixture with from 120 to 150 parts by weight of a thermoplastic powder.
