ABSTRACT:
A method of producing dry-process composition paper board from waste paper. Waste paper is particulated into flakes and the like fragments, conditioned for moisture content, and blended with an adhesive such as a synthetic thermosetting resin prior to forming by compression into mats which are cured under high pressure and temperature to form a rigid, cohesive paper flake board.
The method obviates the need of sorting, pulping, cleaning and purification of waste paper and permits manufacture of structural panel boards in small recycling plants.
