だしく劣るという欠点があった。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a non-asbestos friction material with poor heat resistance. Conventionally, non-asbestos friction materials using aramid mH (aromatic polyamide) are produced by mixing aramid fibers with wood pulp or linter as an organic substance, beating and disintegrating the mixture in a beater, and then adding aramid mN, nylon, etc. After adding friction performance modifiers such as inorganic fillers and cashew dust, thermosetting resin was added and stirred, and a coagulant was added dropwise. After that, paper was made and molded under heat and pressure to make the product. . However, conventional products produced in this manner had the disadvantage that the weight ratio of inorganic matter to the total amount of organic matter excluding the thermosetting resin as a binder was less than 1, and that the heat resistance was extremely poor.
本発明はこのような欠点を除く為に開発されたもので、
基本的配合を示すと次のとおりである。The present invention was developed to eliminate these drawbacks.

~25〃, and the total amount of the aramid pulp, aramid fiber, wood pulp and/or linter is 15~2
0% by weight, and when cashew dust is further added to this, the ratio of the total amount of inorganic matter such as glass powder, potassium titanate fiber, and barium sulfate to the total amount of organic matter excluding thermosetting resin becomes 1 or more. It is blended as follows. This made it possible to greatly improve the heat resistance of the friction material obtained.

混合を行なうことができる。Also, one of the features of the present invention is that glass powder (for example, fiber diameter of about 10
The glass powder mixes well with the pulp during blending and there is little separation due to differences in specific gravity, so it can be mixed uniformly.
