DEVICE FOR FORMING THERMOSETTING RESIN FOAM PLATE AND METHOD OF MANUFACTURING THERMOSETTING RESIN FOAM PLATE

摘要

There are provided a forming device capable of drying at a high speed and of manufacturing a thermosetting resin foam plate more efficiently and stably without multilayering any unnecessary surface material, and a method of efficiently manufacturing a thermosetting resin foam plate therefor. A thermosetting resin foam plate is manufactured by: mixing a resin composition containing at least a thermosetting resin, a foaming agent and a curing agent in a mixer; continuously discharging the resin composition on a traveling air-permeable and flexible surface material, and at the same time covering the upper surface of the resin composition with an air-permeable and flexible surface material; and passing the covered resin composition through a forming device equipped with conveyors having apertures having an aperture area ratio of 15% or more and 80% or less to form and cure the resin composition. Carrying out the formation by using the conveyors having apertures having an aperture area ratio of 15% or more and 80% or less allows water vapor and a foaming gas in the thermosetting resin composition to be released effectively from the apertures, while the thermosetting resin composition is formed and cured on the conveyors.
