Abstract
The invention relates to a novel rare earth composite type brake pad, and relates to the technical field of brake pads. The novel rare earth composite type brake padcomprises, by mass percent, 20-35 percent of animal fibers, 8-12 percent of phenolic resin, 15-30 percent of friction performance conditioning agents, 20-40 percent of packing, 3-8 percent of nitrile rubber powder and 10-15 percent of rare earth. The interface state between base adhesion agents and reinforcing materials is changed effectively through adding of the rare earth, and a fracture mode is damage of interface layer resin rather than interfacial debonding. The solidification speed of a system is increased through the rare earth, a cross-linked network after resin is solidified is more uniform, stress gradient is lowered, the flexibility of the interface resin is improved effectively, and macroscopically, the impact strength is improved.
Description
Technical field
The present invention relates to brake block technical field, be specifically related to the compound brake block of a kind of novel rare-earth.
Background technique
Along with developing rapidly of science and technology, Brake Products is more and more high to the requirement of friction material, except at a high speed, high temperature, outside Security and travelling comfort in the bad working environments situations such as high pressure, in recent years proposed again energy-conservation, environmental protection, the requirements at the higher level such as clean.
In the 12 five-year plan of China, proposed clearly, the most important thing of the national economic development is energy-conservation, environmental protection, and steadily, the lasting Scientific Outlook on Development, makes China develop in a short time stable, a flourishing power.
In 30 years of reform and opening-up, the friction industry of China is also the same with national all trades and professions, there is significant progress, be main from the asbestos friction material at the beginning of last century 80, develop into gradually the semimetal goods of the nineties, later mixing in 2000 optimized and is nonmetal, and non-asbestos (NAO) goods are main.Successively release again in recent years ceramic fibre brake component.And move towards step by step domestic and international market.Although the manufacturer at China's ceramic brake still belongs to minority, universal not enough, really also illustrate that the developing steps forward international market of China's friction industry is drawn close and integrates with.In order to realize the overall technique production domesticization of ceramic brake, China successively last century the nineties introduced many ceramic fiber production technology lines from external, established certain technical foundation for China progressively realizes Brake Products ceramic.
Along with social development and progress, the mankind are more and more high to the requirement of environmental protection, progressively realize urbanization of villages in China, urban population increases year by year, people require also more and more higher to the overall situation of life, and the develop rapidly in recent years of China's automobile has entered prostatitis, the world (producing approximately 1,500 ten thousand per year).So many automobile brake sheets of justing think, if the abrasive dust of every day has severe contamination, the air quality in town and country will be had a strong impact on so, if all brake blocks are all used instead to free of contamination brake block, will there is the change of matter in our inhabitation overall situation ... therefore the fine brake block of clean composite ceramic not hard to imagine, in future transportation industry, fine development prospect and huge market competition potential will be had.
Summary of the invention
Technical problem to be solved by this invention is to provide the compound brake block of novel rare-earth of a kind of Security, travelling comfort and wear resistance aspect superior performance.
Technical problem to be solved by this invention realizes by the following technical solutions:
The compound brake block of a kind of novel rare-earth, is made up of the component of following mass percent:
Animal fibre 20-35%
Phenolic resin 8-12%
Frictional property regulator 15-30%
Filler 20-40%
Nitrile rubber powder 3-8%
Rare earth 10-15%.
The better quality percentage of each component is:
Animal fibre 20%
Phenolic resin 10%
Frictional property regulator 20%
Filler 30%
Nitrile rubber powder 8%
Rare earth 12%.
Described frictional property regulator is one or more in sulphide, graphite or cashew nut oil.
A preparation process for the compound brake block of novel rare-earth, comprises following process step:
1) batching, batch mixing: weigh by formula requirement, send in plough type batch mixer batch mixing 20 minutes;
2) steel backing is prepared: first clean steel backing surface blot with special cleaning machine, then carry out ball blast with Shot-blasting Machine and make steel backing reach the roughness of expection, finally carry out glue spraying processing;
3) hot-forming: be 160-170 DEG C with hot pressing die in temperature by above-mentioned ready material and steel backing, pressure is hot-forming under 25MPa, the time condition that is 10min, in the 1-3min starting, exits 3-6 time in hot pressing, then carries out pressurize;
4) heat treatment;
5) chamfering, fluting, electrostatic spraying, mark, riveted joint, installation accessories, packaging makes finished product;
6) inspection, warehouse-in.
The invention has the beneficial effects as follows: adopt multiple light porous filler, and not containing any metal ingredient, compare with semimetal formula, it is large that brake block of the present invention is opened porosity, density is moderate, porosity ratio is high, and the wear rate of brake block of the present invention is well below resin base brake block under the same conditions, and its stable friction factor heat resistanceheat resistant decline performance and braking travelling comfort are all apparently higher than resin-matrix friction material;
Rare earth add the interface state effectively having changed between substrate adhesive and reinforcing material, making its fracture mode is not interface unsticking, but presents the destruction of interface layer resin; Rare earth is accelerated the curing rate of system, and the homogeneous more of the cross-linked network after resin solidification, has reduced stress gradient, thereby has effectively improved the pliability of interface resin, shows in macroscopic view it is the raising of impact strength.
