Problems solved by technology

Since this type of friction material does not contain organic components (or very little), its high-temperature friction coefficient is stable, its fading is small, its service life is very long, and it can be used in harsh conditions. Good, but...

Embodiment Construction

[0029] The technical characteristics of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Except for silane resin, other raw materials are commercially available.

[0031] The content of each component is weighed according to the following expression, mixed evenly, and pressed at 170-200°C; after post-treatment, processed to the specified size, the friction surface of the brake material is ablated at 600-700°C to obtain the product.

[0032] Table 1 is comparative example and embodiment 1-4: (by weight percent %)

Abstract

The invention discloses a clean ceramic brake material and a manufacturing method of the brake material. The clean ceramic brake material comprises the following compositions in percentage by weight: 3-6% of phenolic resin, 5-10% of silicone/alkyne resin, 15-30% of red copper/brass powder, 4-10% of inorganic binders, 7-12% of hexagonal boron nitride, 15-25% of reinforcing fibers, and the balance of packing, wherein the total weight is 100 parts. The clean ceramic brake material prepared according to the technical scheme of the invention has good high-temperature resistant performance, and canbe used for a long time at a temperature of 800 DEG C; the clean ceramic brake material is extremely stable in friction performance and good in abrasion resistance; especially in the process of application, nearly no black dust is produced, therefore, the cleaning of auto hubs can be maintained; and the braking is comfortable and smooth, and no vibration and brake noise is produced.

Description

technical field [0001] The invention relates to an automobile brake material, in particular to a clean ceramic brake material and a manufacturing method of the brake material. Background technique [0002] At present, automobile brake pads are mostly organic-based semi-metallic, metal-less, metal-free friction materials, and a small amount of ceramic friction materials (including cermets, non-metallic ceramics). Organic-based friction materials are composed of matrix materials (organic binders), It consists of three parts: reinforcing fiber and filler (including friction modifier). The matrix material is phenolic resin, modified phenolic resin, rubber or their mixture. Organic brake materials have the advantages of low cost, simple manufacturing process, low noise, and not easy to damage the pair, but due to their high organic content (15-25%), organic brake materials are preferred at high temperatures. There are disadvantages such as poor braking effect due to increased f...
