としての物性が良くなるためであると推測される。The glass transition temperature of the binder is an index of the hot strength of the glass fiber nonwoven fabric. Same temperature is 90 ℃
When the binder is lower, the glass fiber non-woven fabric does not have sufficient hot strength, the bond between the glass fibers constituting the glass non-woven fabric cannot be maintained during the pressure heat molding of the laminated plate, and the substrate breaks. . The silane coupling agent contained in the binder strengthens the bonding force at the interface between the glass fiber surface and the binder, and further bonds at the interface between the thermosetting resin impregnated in the glass fiber non-woven fabric when manufacturing the laminate and the binder. It also has the effect of strengthening power. When the silane coupling agent is a phenylaminosilane coupling agent, its phenyl group has a strong affinity for the thermosetting resin impregnated in the glass fiber nonwoven fabric, which improves the electrical insulation characteristics of the laminate. Is particularly preferable. In the method for producing a glass fiber nonwoven fabric for laminated plates according to the present invention, the glass transition temperature is 90%.
It is possible to obtain a binder having a temperature of ℃ or higher. In particular, as an epoxy resin that reacts with an aliphatic amine, a combination system of a bifunctional epoxy resin and a trifunctional epoxy resin or a trifunctional epoxy resin has a narrow molecular weight distribution. When such an epoxy resin having a narrow molecular weight distribution is used, the electrical insulating properties of a laminated board tend to be favorable, but the reason for this has not been sufficiently clarified. It is presumed that when the molecular weight distribution of the epoxy resin is narrow, the reaction between the epoxy resin and the aliphatic amine proceeds uniformly and the physical properties of the binder are improved.
