Description
Technical field
The present invention relates to brake block technical field, and in particular to a kind of brake block of anti-corrosion and preparation method thereof.
Background technology
With society and economic fast development, increasing people select automobile as the vehicles, and then automobile
Quantity maintain sustained and rapid growth.But with the quick increase of automobile quantity, problem caused by automobile is also more and more obvious, such as hands over
The problems such as logical crowded, traffic accident, greatly inconvenience and economic loss are brought to people's life.In annual hundreds thousand of friendship
Interpreter thus in, because brake problem the traffic accident such as results in an automobile accident up to nearly ten thousand, directly or indirectly cause huge personnel
Injury and economic loss, therefore to braking automobile performance requirement more and more higher.
Brake block is typically made up of steel plate, bonding thermal insulation layer and brake pad, and its light plate will carry out antirust by application；It is heat-insulated
Layer is made up of adiabatic material；Thermal insulation layer is made up of adiabatic material, it is therefore an objective to which heat-insulated, brake pad is by friction material
Material, adhesive composition；Brake pad is made up of friction material, adhesive, is compressed on brake disc or brake rim during brake and is produced
Friction, while tire produces friction with ground, and the kinetic energy that vehicle is advanced is converted into the heat energy after friction, subtracted so as to reach vehicle
The purpose of speed brake.
During braking automobile, safety that the combination property of friction material will be directly influenced in vehicle traveling process
With it is comfortable, it requires good mechanical strength, good heat endurance and excellent wearability.Brake block quilt in brake
It is squeezed on brake disc or brake rim and produces friction, so as to reaches the purpose of vehicle deceleration brake.At present, the friction in brake block
Material uses semi-metallic more, and its is heat-resist, but its wearability Shortcomings.
And the serious problems that corrosion easily occurs be present in semi-metallic brake pad, this not only can brake block itself strong
Degree, while can also damage mating plate, produce noise during braking, other automobiles can be also damaged while reducing brake block service life
Part, braking quality is reduced, brake failure can be caused to trigger traffic accident when serious.
Therefore a kind of heat-resistant antifriction is needed to damage at present, toughness is strong, is not easy the brake block of corrosion.
The content of the invention
In order to solve the above problems, there is provided a kind of heat-resistant antifriction damage, toughness is strong, is not easy the brake block of corrosion, and the present invention adopts
Use following technical scheme:
A kind of brake block of anti-corrosion, include the raw material of following parts by weight：20~25 parts of ceramic fibre, 5~10 parts of carbon fiber, steel
5~10 parts of fiber, 15~18 parts of phenol-formaldehyde resin modified, 6~10 parts of calcium oxide, 6~8 parts of barium sulphide, 15~20 parts of crystalline flake graphite,
1~3 part of zircon, 5~10 parts of butyl butylbenzene, 10~15 parts of butyronitrile powder, 3~5 parts of molybdenum disulfide, 1~2 part of binding agent, weight are brilliant
5~10 parts of stone flour, 0.5~3 part of zinc oxide, 5~10 parts of rubber powder, 1~2 part of Fluorspar Powder, 0.5~1 part of carborundum.
It is usually that selection removes raw metal in the feed at present, although so to solve the problems, such as the corrosion of brake block
Can solve the problems, such as the corrosion of brake block, but the mechanical performance of brake block can be caused to reduce, reduce the using effect of brake block,
Therefore the present invention adds steel fibre while reducing metal usage amount and preventing brake block occurrence of large-area corrosion and improves brake block
Mechanical performance, while in order to prevent the corrosion of steel fibre, antirust treatment is carried out to steel fibre, brake block machine is being kept to reach
The purpose of brake block corrosion is prevented while tool performance.
Present invention employs the scheme that ceramic fibre, carbon fiber and steel fibre share, skeleton is constructed by fibre structure
Structure, to strengthen the toughness of brake block and intensity, then it can strengthen the heat-resisting of brake block by adding carborundum and zircon
Ability, brake block is prevented because heated situation about deforming occurs.Strengthened by the use of phenolic resin between material
Bonding effect, it ensure that the braking effect and service life of brake block.
In addition, by the present invention in that blanc fixe and chlorine are employed while by the use of barium sulphide and molybdenum disulfide as vulcanizing agent
Change the shared scheme of calcium, can so ensure the stability of vulcanizing agent in the feed, improve the using effect of barium sulphide, while two
Molybdenum sulfide can improve the wearability and seizure resistance of brake block, and extending the service life of brake block prevents brake block locking from triggering
Danger, in addition barium sulphide there is reproducibility, it is possible to reduce metal erosion situation of the invention, strengthen the antirust ability of brake block.
Simultaneously present invention employs crystalline flake graphite, the oxidation resistance and wetability of brake block can be improved, enhances this
The abrasive resistance and antirust ability of invention, while prevent the brake block of the present invention from producing noise, adding graphite can effectively improve
