Embodiment Construction

[0041]The following is a further description of the formulation and manufacturing technology of a high wear-resistant drum brake pad containing cresol resin provided by the present invention.

[0042] 1. The formula and combination of ceramic-like friction materials are divided into two components, A and B, which are described in terms of total weight percentage. The component A includes: precipitated barium sulfate 15-28%; aramid pulp ≤ 3%; whiskers Fiber 15-25%; graphite 15-22%; component B includes: cresol resin binder 8-16%; alkali-free E-glass fiber ≤ 3%; antimony trisulfide 1-4%; copper powder 2-6%; powdered nitrile 2-6%; mica 1-5%; ceramic fiber 5-10%. Wherein, whisker fiber is the combination of artificial calcium carbonate whisker and natural acicular wollastonite whisker, and its weight ratio is 1:1.2-1.5; Graphite is the combination of artificial graphite, natural graphite and expanded graphite, and its weight ratio is 1:1. : 1: 1.5-2.

Abstract

The invention relates to a cresylic reisn containing high wear resistance drum type brake pad and a manufacturing method. The brake pad is characterized by applying cresylic reisn as an adhesive, but not containing asbestos, cadmium, lead, mercury and a compound of asbestos, cadmium, lead and mercury and metal fibers. By reasonable transformation and combination of multiple component materials, the ceramic type brake pad is obtained; the temperature resistance of the ceramic type brake pad is higher than that of a brake pad made of pure phenolic resin and brake pads made of modified phenolic resin such as cashew nut shell liquid and butyronitrile; and furthermore, the cresylic reisn containing high wear resistance drum type brake pad has the characteristics of flexibility, low hardness and extremely high wear resistance.

Description

technical field [0001] The patent of the present invention relates to the technical field of high wear-resistant drum brake pads for heavy-duty vehicles, and more specifically relates to a high wear-resistant drum brake pad mixed with cresol resin and its manufacturing method. Background technique [0002] As a key part of heavy-duty vehicle braking and wearing parts, the performance of drum brake pads directly affects the reliability and safety of vehicle operation. With the development of the automobile industry, the requirements for the performance of brake pads are getting higher and higher, especially the heavy-duty vehicles used in the Chinese market are generally overloaded and overspeeded, which will cause great damage to the brake pads. Users not only require brake pads to ensure sensitive braking, but also require them to be wear-resistant and have a long service life. The reality of extreme use shows that the long-term coexistence of semi-metal, metal-less, sinte...
