Description
Technical field
The present invention relates to brake block technical field, particularly relate to a kind of disc brake pad.
Background technology
Along with the rapid growth of Chinese automobile volume of production and marketing, Chinese automobile manufacture level and technical merit also obtain stable development
And raising.Also it is good opportunities and challenges to the automobile component part supply business having independent intellectual property right and research and development ability.Brake
Disc is one of parts most commonly seen in automobile, well known, by steel disc and the rubbed substrate group being attached on steel disc
Become.In automobile brake sheet production process, friction substrate is generally fixed on sheet metal by machine riveting method, and this method is deposited
The shortcoming such as low in friction material intensity, utilization rate is low.Prepare brake block with bonding replacement riveting process at present.Therefore, with
During bonding process prepares brake block, the quality of brake block depend on steel disc with friction substrate between bonding firmly
Degree, therefore, the quality of used adhesive directly influences the performance of brake block.Existing brake block adhesive is viscous
The aspects such as knot property, thermostability are the most less desirable.
Summary of the invention
The technical problem existed based on background technology, the present invention proposes a kind of disc brake pad, and it is heat-resist, friction
Excellent in stability, service life is long.
