Abstract
The invention relates to a ceramic fiber composite brake pad, which comprises a friction layer and a heat dissipation bonding layer. The heat dissipation area ensures that the advantages of all materials are fully exerted in the friction material by reasonably matching various components, has good temperature resistance, good thermal stability and lower heat conduction force, and meets the technical requirements of high wear resistance, high speed, safety and the like of the brake pad.
Description
Technical Field
The invention relates to the field of automobile parts, in particular to a ceramic fiber composite brake pad.
Background
In the braking system of the automobile, a brake pad is the most critical safety part, and the quality of all braking effects plays a decisive role. The working principle of the brake mainly comes from friction, and the kinetic energy of the vehicle is converted into the heat energy after friction by using the friction between a brake pad and a brake drum and between a tire and the ground, so that the vehicle is stopped. A good and efficient braking system must provide a stable, sufficient and controllable braking force, and have good hydraulic transmission and heat dissipation capability, so as to ensure that the force applied by the driver from the brake pedal can be sufficiently and effectively transmitted to the master cylinder and the slave cylinders, and to avoid hydraulic failure and brake recession caused by high heat.
Disclosure of Invention
The invention aims to provide a ceramic fiber composite brake pad to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: the ceramic fiber composite brake pad comprises a friction layer and a heat dissipation bonding layer, wherein the heat dissipation bonding layer is positioned between the friction layer and a steel backing, and is prepared from the following components in parts by weight: 14-15 parts of basalt fiber, 15-17 parts of nano silicon dioxide modified phenolic resin with epoxy groups, 1.5-2 parts of melamine, 3-4 parts of nano aluminum oxide, 10-13 parts of red copper fiber, 7-10 parts of steel fiber, 5-7 parts of polyimide, 4-5 parts of expanded vermiculite, 0.3-0.6 part of sodium dodecyl sulfate, 0.3 part of nano zinc oxide and 3-5 parts of nitrile rubber;
the friction layer is prepared from the following components in parts by weight: 4-8 parts of PROMAXON-D calcium silicate particles, 9-11 parts of ceramic fibers, 10-15 parts of diabase fibers, 5-8 parts of iron yellow, 1-1.5 parts of tin bronze powder, 7-12 parts of carbon fibers, 5-8 parts of polyimide, 9-11 parts of needle-like wollastonite powder, 1-3 parts of zinc sulfide, 2-5 parts of tungsten disulfide, 2-5 parts of polytetrafluoroethylene, 15-17 parts of nano silicon dioxide modified phenolic resin with epoxy groups, 3-5 parts of nitrile rubber and 1-1.5 parts of melamine.
Preferably, the middle part of the friction layer is provided with a drainage ditch, and the bottom of the drainage ditch is flush with the heat dissipation bonding layer.
PROMAXON-D basalt fiber particles (American Chemical Abstracts Service (CAS) accession number PROMAXON-D: 1344-95-2) are high porosity calcium silicate products, PROMAXON-D is produced by Promat International Inc. Belgium Europe, and the Holland LAPINUS fiber Co., Ltd is the only agent in the global friction material market.
The diabase fiber does not contain asbestos inorganic substances, has good high-temperature stability and extremely low non-fibrous substance content, can reduce noise, and has good adaptability, good softness, good dispersibility, good bonding force with resin and small irritation to skin.
Tungsten disulfide can be used as lubricant, and has better performance than molybdenum disulfide, lower friction coefficient and higher compressive strength. The device is used for high temperature, high pressure, high rotating speed, high load and operation in chemically active medium. The filling material configured with polytetrafluoroethylene, nylon and the like can be used for manufacturing self-lubricating components.
The needle-shaped wollastonite powder has the characteristics of high purity, good crystallization, strong fluidity, low linear expansion coefficient and corrosion resistance.
The tin bronze is bronze taking tin as a main alloy element, and the alloy has high mechanical property, antifriction property and corrosion resistance, is easy to cut and process, has good brazing and welding properties, small shrinkage coefficient and no magnetism; zinc addition improves castability.
The polyimide has excellent mechanical property, the decomposition temperature is between 500 ℃ and 600 ℃, and the accumulated temperature of the material can be quickly diffused, so that the friction material is effectively prevented from entering a heat fading stage.

The first, second and third embodiments and the brake pad are compared and tested, and the results are as follows:
the verification result shows that the product has more excellent friction performance, good wear resistance, high-temperature wear resistance and heat fading resistance. During the temperature rise process from 200 ℃ to 350 ℃, the brake pad of the comparative example 1 generates larger heat fading, and the temperature drops from 0.45 at 200 ℃ to O.29 at 300 ℃ and reaches 35.5 percent. In the aspect of abrasion, before 200 ℃, the difference between the comparative example 1 and the brake pad of the invention is not large, namely the low-temperature abrasion of the two materials is close; after 200 ℃, the invention has excellent high-temperature bonding effect and improves the wear resistance of the material by times. At 350 ℃, the wear rate of example 1 is only o.16, which is much lower than 0.25 of the brake pad of the comparative example.
In the following, decay tests are performed on example 3 and comparative example 1, wherein the speeds are 50, 100 and 130km/h, and the brake pipe pressures are 2, 4, 6, 8 and 10MPa, respectively, so as to examine the stability of the friction coefficient of the brake pad under different speeds and different pressures.
As shown in fig. 2-3, the brake pad of the embodiment 3 has 6 percent of first attenuation and 13 percent of second attenuation; comparative example 1 brake pad one decay 29%, two decay 28%; obviously, the recession rate of the ceramic-based brake pad is far less than that of the brake pad of the comparative example 1, and the thermal stability performance of the ceramic-based brake pad is good. In the decay test, the first 3 times of braking are taken as a benchmark test, the first decay is that 10 times of continuous braking are carried out at the speed of 100 km/h, and the recovery test is that 12 times of braking are carried out under the conditions of 50 km/h and air cooling. The second attenuation is the same as the first attenuation except that the continuous braking is carried out for 15 times at the speed of 100 km/h.
The friction coefficient of the brake block shows insensitivity to braking times, the whole curve has no obvious 'big rise and fall', the fluctuation range of the friction coefficient is within 0.08, and the heat resistance of the material is good.
