(Technical Field) This invention relates to an epoxy resin composition for glass epoxy laminates. More specifically, the present invention relates to an epoxy resin composition for glass epoxy laminates that is useful as a printed wiring board substrate, is low cost, and has excellent heat resistance and chemical resistance. (Background Art) Glass epoxy laminates used as substrates for printed wiring boards have conventionally been made from epoxy resin compositions containing bisphenol A type epoxy resin as a main component. Conventionally, in order to improve the heat resistance of this glass epoxy laminate, an appropriate amount of phenol novolac type epoxy resin, cresol novolac type epoxy resin, or multi-tubular epoxy resin was added to the main component bisphenol A type epoxy resin. It was mixed. However, although the conventionally used phenol novolac type epoxy resin is the lowest-cost additive component used so far, it has the disadvantage of poor heat resistance and chemical resistance. . Although multifunctional epoxy resins have a high Tg, they have the disadvantage that unreacted glycidyl ether groups tend to remain, resulting in a high rate of smearing. Currently, cresol novolak type epoxy resins are often used, but in this case, it is necessary to set up a manufacturing process to remove unreacted cresol during production, which increases costs. There was a problem. On the other hand, in order to improve the disadvantage of high cost of these novolak type epoxy resins, attempts have been made to use phenol novolak or cresol novolak as substitute materials. However, in this case, if phenol novolak or cresol novolak is used alone, the epoxy resin composition will have a long gel time and will remain unused even after molding due to its low dependence on curing accelerators such as imidazole. Reactants remain,
The drawback was that the quality of the resulting laminate was poor. As a measure to improve this drawback, attempts have been made to use dicyandiamide as a curing agent with an accelerating effect on phenol novolak, but a new drawback has arisen: poor chemical resistance. For these reasons, it has been strongly desired to realize a new epoxy resin composition for glass epoxy laminates that is low cost and has excellent heat resistance and chemical resistance. (Object of the invention) This invention was made in view of the above circumstances, and it improves the drawbacks of conventional epoxy resin compositions, is low cost, and has excellent heat resistance and chemical resistance. An object of the present invention is to provide an improved epoxy resin composition for glass epoxy laminates. (Disclosure of the Invention) In order to achieve the above object, the epoxy resin composition for a glass epoxy laminate useful as a substrate for a printed wiring board of the present invention contains 100 parts by weight of a bisphenol A type epoxy resin or a brominated resin thereof. For bisphenol A type novolac epoxy resin or bisphenol A type novolac 5 to 30
parts by weight, 2 to 8 parts by weight of a dicyandiamide curing agent, and 0.05 to 0.5 parts by weight of at least one imidazole compound as a curing accelerator. The type of bisphenol A epoxy resin used in this invention is not particularly limited, and
It may also be brominated. Furthermore, there are no limitations on the type of bisphenol A type novolac epoxy resin and bisphenol A type novolac used in the present invention, but those shown in the following formula are preferred. That is, the preferred bisphenol A type novolak epoxy resin has the formula It has the structure shown by n=2~10 as the main component.
Particularly preferably used are the following. As a bisphenol A type novolak, the formula It has the structure shown as, and its main component is n=2
~10 are particularly preferably used. The curing accelerator includes at least one imidazole compound, such as 2-ethyl-4-methylimidazole (2E4MZ), 1-cyanoethyl-2-phenylimidazole, 1-methylimidazole, and 1,2-dimethylimidazole. etc. are used. The method for producing the composition is not particularly limited, and kneading is performed using a known kneader or the like. EXAMPLES Next, the epoxy resin composition for glass epoxy laminates of the present invention will be described in more detail with reference to Examples. Example 1 The following blending ratio (1) Bisphenol A type epoxy resin (DER
-511) 85 (parts by weight) (2) Bisphenol A type novolac epoxy resin 15 (3) Dicyandiamide 3.0 (4) An epoxy resin composition produced by kneading a mixture consisting of 2E4MZ 0.2 and 7628 40 to type glass cloth
The resin cloth was impregnated with ~42% volume. Eight sheets of this resin cloth were stacked together, and 18 μm copper foil was layered on both the top and bottom, which were then heated and pressed to create a copper-clad laminate with a thickness of 1.6 mm. The properties of this laminate were evaluated. Table this result.
Shown in 1. Both heat resistance and alkali resistance were good, and moreover, better sheathing characteristics and smearing characteristics were obtained than in the case of a comparative example described below using conventional additive components. Example 2 In the same manner as in Example 1, the following compounding ratio (1) Bisphenol A type epoxy resin (DER
-511) 90 (parts by weight) (2) Bisphenol A type novolac epoxy resin 10 (3) Dicyandiamide 3.0 (4) A copper-clad laminate was produced using a conglomerate consisting of 2E4MZ 0.2.
Its characteristics are shown in Table-1. As in Example 1, both measling and smear properties were good. Comparative Examples 1 to 3 Copper-clad laminates were made in the same manner as in Example 1 using a phenol novolak epoxy resin, a cresol novolak epoxy resin, and a tetrafunctional epoxy resin instead of the bisphenol A novolak epoxy resin. A plate was prepared and its properties were evaluated. As shown in Table 1, compared to Examples 1 and 2, the heat resistance and alkali resistance were inferior (Comparative Example 1), and the measling and smearing properties were also inferior.

The results of the characteristic evaluation and cost evaluation are shown in Table 2. Both alkali resistance and cost were good. Comparative Example 4 A varnish and a laminate were produced in the same manner as in Example 3, except that a phenol novolak type epoxy resin was used in place of the bisphenol A type novolak in Examples 3 and 4. Its characteristics and cost were evaluated. The results are shown in Table-2. Alkali resistance was particularly poor. Comparative Examples 5-6 Varnish and copper-clad laminates were produced in the same manner as in Example 3 using phenol novolak. The cost of the varnish and the properties of the laminate were evaluated, and the results are shown in Table 2. Although the cost was reduced compared to Comparative Example 4, the alkali resistance was poor. Comparative Examples 7 to 9 Varnishes and copper-clad laminates were obtained in the same manner as in Example 3 except that dicyandiamide as a curing agent and an imidazole compound (2E4MZ) as a curing accelerator were not used. Evaluate the properties of varnish and laminate, and table-
