Description
Technical field
The present invention relates to brake block technical field, particularly relate to a kind of wear-resistant brake block.
Background technology
In the brake system of automobile, brake block is the breaking piece of most critical.Brake block typically by steel plate,
Bonding thermal insulation layer and brake pad are constituted.Wherein, steel plate to come antirust through application；Thermal insulation layer is by not conducting heat
Material composition；Brake pad is made up of friction material, binding agent, is compressed in brake disc or brake during brake
Producing friction on drum, tire produces friction with ground simultaneously, after the kinetic energy that vehicle is advanced is converted into friction
Heat energy, thus reach the purpose of vehicle deceleration brake.During braking automobile, friction material comprehensive
Performance by the safety directly influenced in vehicle traveling process and comfortable, its require to have good mechanical strength,
Good heat stability and excellent wearability.Adhesive is the main component of friction material, most-often used
Adhesive is phenolic resin, and it has excellent heat resistance and mechanical performance, electrical insulating property and molding add
Work is functional, and raw material is easy to get, low price, technique and the advantage such as the equipment of production is simple.But common phenol
Its wearability of urea formaldehyde is the most less desirable, and the brake block made with it exists much higher hard, fragility greatly,
Cure shrinkage is big, and the defect that coefficient of thermal expansion is big causes the performance of brake block to be remarkably decreased.
Summary of the invention
The technical problem existed based on background technology, the present invention proposes a kind of wear-resistant brake block, and it is wear-resisting
Performance and excellent shock resistance, heat-resist, cure shrinkage is little.
The wear-resistant brake block of one that the present invention proposes, including steel plate, thermal insulation layer and brake pad；Brake pad leads to
