Title: Manufacture of solvent-free laminated board
Inventor: FUJIOKA ATSUSHI
IPC: C08G59/00
Filed: 1981-04-23
Abstract: PURPOSE: To provide the titled laminated board in a short molding time, by impregnating a substrate with a solvent-free resin composition obtained by uniformly mixing a specific epoxy resin in a liquid phase with a cycloaliphatic amine as a curing agent, and hot-pressing the impregnated product.  
     CONSTITUTION: An epoxy resin having ≥2 epoxy groups per one molecule on an average (e.g. bisphenol-A diglycidyl ether epoxy resin) is mixed with a cycloaliphatic amine (e.g. 4,4'-diaminodicyclohexylmethane), and stirred uniformly under heating until each component becomes liquid. The amount of the amine is preferably 1.0 amine equivalent per 1 epoxy equivalent of the epoxy resin. The solvent-free resin composition thus obtained is applied to a substrate. A necessary number of the substrates are stacked together, and hot-pressed preferably with an edged mold for 5W10min.
