Phenol resin, polyester resin, epoxy resin, etc. are used as plastics, and they are used in large quantities in the fields of home appliances and automobiles. Recent developments in these fields include the miniaturization of VIRs, the lighter weight of automobiles, and the increasing probability that Japanese products will be used all over the world. For this reason, there is a strong demand for parts used in these applications to be smaller, lighter, more resistant to environmental changes, and lower in cost.

示すことが判つた。表―1に結果をまとめた。[Formula] R 4 =H, CH 3 m, n are integers of 0 to 2. The biphenols herein refer to all biphenols and biphenol derivatives, such as biphenols and alkylbiphenols.
In addition, phenols include biphenols, alkylphenols, resorcinols, etc., alkylbenzenes include toluene, xylene, acenaphthene, anthracene, etc., and aldehydes include:
Refers to substances having an aldehyde group, such as formaldehyde, paraformaldehyde, benzaldehyde, acetaldehyde, butyraldehyde, acroin, and the like. Furthermore, epoxy resin compositions refer to all compositions containing epoxy resins having a biphenol structure in their skeleton (hereinafter referred to as biphenol novolak type epoxy resins), and generally include epoxy resins,
Consists of curing agent, curing accelerator, filler, pigment, mold release agent, surface treatment agent, flame retardant, etc. The epoxy resin referred to here includes the biphenol novolak type epoxy resin according to the present invention and other general epoxy resins such as biphenol type epoxy resin, phenol novolak type epoxy resin, biphenol novolak type epoxy resin, and cresol novolak type epoxy resin. In all cases, the biphenol novolak type epoxy resin of the present invention is essential and may be used in combination with one or more other epoxy resins. Further, as the ratio of the biphenol novolac type epoxy resin of the present invention is increased, the faster curing properties and heat resistance improve. The curing agent refers to anything that crosslinks with the epoxy resin, such as phenol novolaks, amines, and acid anhydrides. Furthermore, curing accelerators include imidazoles, tertiary
The filler is silica,
Alumina, clay, asbestos, calcium carbonate, glass, etc.; surface treatment agents include filler modifiers such as silane coupling agents, titanium coupling agents, and aluminum coupling agents; flame retardants include boron compounds, phosphorus, etc. Compounds, antimony, halides, etc. In particular, as for the composition for electronic parts, 50% or more of the epoxy resin is the biphenol novolak type epoxy resin of the present invention, the rest is a cresol novolak type epoxy resin, and the curing agent is phenol novolak type epoxy resin.
Preferably, the filler is silica. The present invention is based on the discovery that the strength of the resin itself and the strength after crosslinking can be significantly improved by incorporating biphenol into the skeleton. This is because biphenol not only has a rigid structure in which benzene rings are directly bonded, but also has a small OH equivalent (and when epoxidized, the epoxy equivalent is also small), making it possible to achieve high strength crosslinking. As a result, not only the curing reaction was accelerated and quick curing properties were obtained, but also advantages in heat resistance and moisture resistance were obtained, such as a higher thermal decomposition temperature and a lower water absorption rate of the cured product. The fast curing properties enable high-cycle rationalization of molding and pressing processes, leading to cost reductions. In addition, improved heat resistance and moisture resistance support the quality of plastic parts when they are made thinner and more compact. The strength of biphenol novolac type epoxy resins and resin compositions depends on the proportion of biphenol. The higher the ratio of biphenol, the higher the strength, so it is necessary to determine the amount of biphenol in the resin and the amount of biphenol novolak type epoxy resin used in the composition depending on the purpose. From the viewpoint of strength, it is preferable that 50% or more of the epoxy resin be biphenol type epoxy. An example of application to a low-pressure encapsulation molding material will be explained below. All parts used in the examples are parts by weight, and the raw materials used in the examples are as follows. Epoxy resin: Biphenol novolac is made by reacting biphenol and formaldehyde (1:0.8 in molar ratio) with an oxalic acid catalyst, and is subjected to an addition ring-closing reaction with epichloropidrine to the hydroxyl group in a molar ratio of 1:5 using a sodium chloride catalyst. Resin obtained after purification Epoxy resin: Phenol-modified biphenol novolak (phenol/biphenol = 1/2
Weight ratio) of epoxidized resin Epoxy resin: Biphenol modified phenol novolak (phenol/biphenol = 3/1

-80 Curing catalyst: Sumitomo Chemical Sumikiure D Filler: Ryumori Fused silica Surface treatment agent: Nippon Unicar A-186 Mold release agent: Hoechstwax OP Example As an epoxy resin,,,ECN,/
Six levels of ECN=2/1 and /ECN=1/2 are taken, and a curing agent is added thereto in a ratio of epoxy group/phenolic hydroxyl group=1/1 (mole ratio) for a total of 30 parts. Further, 0.2 parts of a hardening agent catalyst, 70 parts of a filler, 0.3 parts of a surface treatment agent, and 0.3 parts of a mold release agent were added and mixed, and then kneaded using a co-kneader to form a material. As a result of comparing and examining the curability, heat resistance, and moisture resistance of a total of six materials, it was found that when the resin composition according to the present invention was used, the characteristics were extremely superior to those when conventional ECN was used. It has also been found that the more biphenol novolac type epoxy resin is used, especially when more than half of the epoxy resin is used, the better the properties are. Table 1 summarizes the results.
