Although such a brominated epoxy resin has good flame retardancy, it generates harmful hydrogen halide (hydrogen bromide) gas during combustion.
Its use is being suppressed. Therefore, a composition in which a non-halogen flame retardant, for example, a nitrogen compound, a phosphorus compound, an inorganic compound, or the like is blended with an ordinary epoxy resin has been developed. However, these flame-retardant additives have a negative effect on the curing of the epoxy resin in a nitrogen-based composition, a phosphorus-based composition lowering the moisture resistance of a cured composition, and an inorganic compound impregnating a glass cloth with the composition. There is a problem such as a decrease in performance, and it is difficult to put it to practical use. The present invention has been made to solve the above-mentioned drawbacks, and does not use halogen as a flame-retardant method, does not generate hydrogen bromide which is a toxic gas at the time of combustion, and has heat resistance, moisture resistance, moldability, and the like. An object of the present invention is to provide a resin composition for a glass epoxy copper clad laminate excellent in water resistance.

It is preferable that if the nitrogen content is less than this, good flame retardancy cannot be obtained. The mixing ratio of the nitrogen-containing phenolic resin is adjusted so that the hydroxyl equivalent is 0.8 to 1.2 with respect to the epoxy equivalent, and it is desirable to add 10 to 50% by weight to the whole resin composition. When the compounding ratio is less than 10% by weight, flame retardancy and peeling strength cannot be obtained, and when it exceeds 50% by weight, moldability decreases. The optimum range is preferably 20 to 35% by weight.

The present invention is characterized in that no halogen is used as a flame-retardant method, and glass epoxy which is excellent in heat resistance, moisture resistance, moldability, etc. without generating hydrogen bromide which is a toxic gas at the time of combustion. A resin composition for a copper-clad laminate was obtained. A novolak-type epoxy resin cured with a nitrogen-containing phenol resin is particularly effective as a flame-retardant resin, and the use of this flame-retardant resin covers the weakness in the properties of the phosphate ester of the main flame-retardant material. On the other hand, the amount of the inorganic filler used can be kept in an appropriate range by the bond between the flame retardant resin and the phosphate ester.
