Bicycle is also known as bicycle or bicycle, it is common that refer to the small-sized ground vehicle of two wheel drive, with foot pedal as power, is the vehicles of a kind of environmental protection.China is the country that bicycle owning amount is most in the world, and bicycle, as the vehicles of environmental protection, is not only able to energy-saving and emission-reduction, reduces the air pollution granule of motor vehicle emission, and can improve the physique of the nation people.
Brake in bicycle is the vitals concerning people's life, and the brake cable in brake then undertakes important linkage effect.One end of brake cable connects handle, and the other end connects brake block, plays power transmission effect, and its serviceability and life-span determine the normal use of whole brake.Existing brake cable is mainly made up of outer sebific duct, cable wire and connection terminal, in brake process, owing to there is contact between outer sebific duct and cable wire, and contact area is big, cable wire can produce a certain degree of abrasion by external rubber tube inner wall, the probability that outer sebific duct galls if things go on like this easily occurs, makes cable wire suffer erosion, affect brake cable and the serviceability of brake entirety and life-span.
Summary of the invention
For the demand, the invention provides the outer sebific duct of a kind of high abrasion bicycle brake line, the configuration of this outer sebific duct composition is rationally, stable performance, anti-wear performance highlights, and can effectively reduce the probability that outer sebific duct is galled by cable wire, promotes the overall serviceability of brake cable and life-span.
The present invention is the outer sebific duct of a kind of high abrasion bicycle brake line, and main component and the percentage composition proportioning thereof of this outer sebific duct be: silicone rubber powder 50%-60%, carbon fiber wire 15%-20%, wear resistant filler 15%-20%, remaining is auxiliary agent.
In a preferred embodiment of the present invention, main component and the percentage composition proportioning thereof of described outer sebific duct be: silicone rubber powder 55%-58%, carbon fiber wire 16%-18%, wear resistant filler 18%-20%, remaining is auxiliary agent.
In a preferred embodiment of the present invention, the specification of described carbon fiber wire is 2K or 3K, and average length is 1.2-1.3mm.
In a preferred embodiment of the present invention, described wear resistant filler is made up of sericite in powder and molybdenum dioxide powder, and both mass percents are about 5:1.
In a preferred embodiment of the present invention, the average particle size of described sericite in powder is 300 mesh.
In a preferred embodiment of the present invention, described auxiliary agent includes reinforcing agent, vulcanizing agent, heat-resisting additive and age resistor etc..
Present invention is disclosed the outer sebific duct of a kind of high abrasion bicycle brake line, rationally, serviceability is stable for the configuration of this outer sebific duct composition, and anti-wear performance highlights, and can effectively reduce the probability that outer sebific duct is galled by cable wire, promotes the overall serviceability of brake cable and life-span.
Detailed description of the invention
Below presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
