ABSTRACT:
A composite dry process hardboard includes a hardboard panel consisting of pressed defibrated and refined wood chips, plus a surface layer of paper cemented to the hardboard by a cured resin made from phenolic resin mixed with water and ethylene glycol. If desired, an embossed pattern may be incorporated into pressing the paper overlay. In the subject process, first a mass of defibrated wood chips is mixed with a binding agent, the mass is then formed into a mat which is coated with a mixture of phenolic resin and polyhydric compound such as a polyhydric alcohol having a boiling point higher than water. Then, a dry sheet of paper is laid on the mat and the composite structure is then cured by the application of heat and pressure.
