Example Embodiment

[0046] Example

[0047] Hereinafter, the phenol resin molding material of the present invention will be explained by examples and comparative examples, but the present invention is not limited by these examples at all.

[0048] The material mixture blended in the proportions (parts by mass) shown in Table 1 was kneaded by heating rollers with different rotation speeds, and cooled into flakes, and the cooled material was pulverized to obtain granular molding materials. Table 1 shows the workability at the time of manufacturing the molding material and the performance evaluation results of the molded product obtained by molding the molding material. In addition, the kneading conditions of the heating roll are set at high speed side / low speed side=20 / 14rpm, temperature at high speed side / low speed side=90 / 20℃, and set the fluidity between 5-10 Adjust the mixing time between minutes.

[0049] The complexes used in the examples and comparative examples are as follows

Abstract

A phenolic resin molding material characterized by comprising: a novolac-type phenolic resin having an ortho/para binding ratio of 1.2 to 3.0 inclusive; and an oxidized polyethylene having an acid value of 10 to 40 mgKOH/g inclusive. Preferably, the content of the oxidized polyethylene is 0.5 to 10 parts by mass inclusive relative to 100 parts by mass of the novolac-type phenolic resin.
