Abstract
The invention discloses a kind of novel wear resistant brake block, by metal dust, organic binder bond, glass fibre, filler, the component mixed preparing such as accelerator is formed for the invention.The present invention improves brake material temperature tolerance by the ferrous alloy atomized powder for adding Lay Wu Shi phases to strengthen, and heatproof temperature is at least up to 350 DEG C, improves high temperature friction coefficient, improves wearability；Due to the special crystal structure of Laves phases, antisticking is worn and torn and has solid lubrication to act on, and also has effect to improving friction stability.The addition of nanometer acrylonitrile-butadiene rubber powder, can toughening matrix, with the optimum organization of phenolic resin as matrix resin and reinforcing fiber, filler etc., being improved particularly stability of friction coefficient has effect, make that alloyed powder and inserts be not easy to wear to come off, improve wearability, novel brake pad prepared by the formula is on probation to be shown, brake is reliable and stable, and noise is small.
Description
Technical field
The present invention relates to Material Field, and in particular to a kind of novel wear resistant brake block.
Background technology
Brake block is widely used in motor vehicles, is the part that braking function is realized by rubbing action, is related to machine
Can motor-car safely and reliably travel.Friction material is the key material on brake block, and its performance quality directly affects system
The braking effect of dynamic device.Preferable friction material should have good heat endurance, and coefficient of friction becomes at high temperature to make brake block
Change is small, and thermal wear is small, improves functional reliability, increases the service life；There is less brake noise, improve vehicle riding comfort, subtract
The small noise pollution to environment;In addition, should also have good mechanical strength, surface wear is smaller over the ground, environment protecting is good.
The content of the invention
Present invention aim at, there is provided a kind of novel wear resistant brake block, the technical solution adopted by the present invention is as follows：
A kind of novel wear resistant brake block, it is characterised in that be mixed with by weight percentage by following components and formed：
Metal dust 12-50 parts
Organic binder bond 10-35 parts
Glass fibre 5-10 parts
Filler 10-30 parts
Accelerator 1-5 parts.
One of preferably, it by granularity is the Lay Wu Shi phase reinforced iron-base alloy gas of 58um that described metal dust is
Atomized powder is with granularity for the copper powder of 65um is 2 according to weight ratio:1 mixing composition.
One of preferably, described organic binder bond is mixed by nanometer acrylonitrile-butadiene rubber powder with modified phenolic resin
Composition.
One of preferably, described glass fibre is that the steel fibre by length in 1-8mm mixes group with carbon fiber
Into.
One of preferably, described filler is the molybdenum bisuphide by graphite, sulphur, nanoscale alundum (Al2O3),
One or more mixing composition such as inorfil.
One of preferably, described accelerator is by C12H20N2S6And C6H12N2S4Mixing composition.
The present invention is relative to the beneficial effect of prior art：Ferrous alloy by adding Lay Wu Shi phases to strengthen of the invention
Atomized powder, improves brake material temperature tolerance, heatproof temperature is at least up to 350 DEG C, improves high temperature friction coefficient, improves resistance to
Mill property；Due to the special crystal structure of Laves phases, antisticking is worn and torn and has solid lubrication to act on, and is also had to improving friction stability
Effect.The addition of nanometer acrylonitrile-butadiene rubber powder, can toughening matrix, the optimization with phenolic resin as matrix resin and reinforcing fiber, filler etc.
Combination, being improved particularly stability of friction coefficient has effect, makes that alloyed powder and inserts be not easy to wear to come off, and improves wearability, and this is matched somebody with somebody
Novel brake pad prepared by side is tried out and shown, is braked reliable and stable, and noise is small.
