PROBLEM TO BE SOLVED: To attain material recycling of waste and obtain a board for construction material superior in mechanical physical property balance by blending and molding a thermosetting resin on a crushed matter of a printed board. SOLUTION: 1-30 pts.wt. of thermosetting resin is blended to 100 pts.wt. of a crushed matter of a printed board obtained by crushing printed board waste to form a construction material board. The printed board crushed matter may be the crushed matter of a rich non-metallic component recovered by separating a metal component and the non-metallic component. In addition, 98 wt.% or more of the printed board crushed matter is preferably the particular diameter of 1 mm or shorter. Furthermore, the printed board crushed matter is the mixed powder of hard epoxy resin after thermal curing and glass fiber, the mixed powder of hard phenol resin after thermal curing and paper or the mixture of these mixed powder is representative matter. Thereby material recycling of waste is attained, and a construction material board superior in mechanical physical property balance can be obtained. |
