Glass fiber-reinforced phenolic resin molded plates can be produced using compound methods or prepreg methods, depending on the form of the molding material, but either method requires thickening, etc. to make it easier to handle during the manufacturing process. It was necessary to go through several complicated processes, and it was manufactured in batches, so continuous mass production was not possible.

も好適な溶剤である。 The impregnating composition used in the continuous production method of glass fiber reinforced phenolic resin molded plates of the present invention has a moisture content between the resin component and water in the composition.
It is necessary that the resol type liquid phenolic resin is adjusted to 40wt.% or less, and preferably,
Specific gravity 1.18-1.30, viscosity 0.5-100 poise, PH5-7,
The non-volatile content has been adjusted to 60wt.% or more. If alcohols such as methanol are included as a solvent in this impregnating composition, the curing properties will deteriorate, making it necessary to perform a forced drying process such as preheating, or causing problems with the resulting resin molded plate. It is preferable to use only water as a solvent since it has disadvantages such as deterioration of combustion characteristics. In particular, in the case of water as a solvent, the viscosity of the impregnating composition can be controlled by adjusting the amount of water, and the impregnating properties of glass fibers can be improved. It is the most suitable solvent because it is involved in the flame retardancy of the resulting resin molded plate.

Inorganic fillers such as calcined gypsum, aluminum hydroxide, clay, mica, talc, and calcium carbonate, and fine inorganic fibers such as fine rock wool, potassium titanate, and wollastonite are used to improve the flame retardancy of the resulting molded plate. This will improve the anti-crackling properties. Moreover, antimony trioxide, chlorinated paraffin, trichloroethyl phosphate, etc. can also be used together as a flame retardant aid.
