Abstract
The invention relates to a carbon brush for a starting motor of an automotive engine and a production method thereof, and the carbon brush is characterized by comprising the following components: mixed graphite powder, copper powder and niobium diselenide, wherein the mixed graphite powder comprises the following components: graphite powder, asphalt and phenolic resin. The preparation method of the carbon brush for the starting motor of the automotive engine is characterized by comprising the following steps of: firstly preparing the mixed graphite powder, adding the asphalt into the graphite powder to mix at a temperature of 220 DEG C and adding the phenolic resin after the temperature is slowly lowered below 100 DEG C; then mixing at a temperature of 90 DEG C and grinding the dried powder into the mixed graphite powder for standby; adding the copper powder and the niobium diselenide into the mixed graphite powder in a manner of dry powder, mixing in a dry mixer and pressing the carbon brush for the starting motor of the automotive engine. The invention has the advantages that as resin modified asphalt is adopted as an adhesive agent, the carbon brush has the advantages of a resin adhesive agent and an asphalt adhesive agent, so that the strength of the carbon brush is improved, and the carbon brush is not superhard; and as the niobium diselenide is used as a lubricating agent, the lubrication problem of the carbon brush is effectively solved.
Description
Technical field
The present invention relates to a kind of automobile engine starting carbon brush for electric machine and production method thereof.
Background technology
Automobile becomes more and more important in the middle of the people's lives of China, people are also increasingly high to the requirement of automobile various aspects of performance, forces to such an extent that whole automobile industry improves constantly technical merit, all in addition parts all towards advancing with the direction in life-span with automobile.As the carbon brush of the main consumable accessory of generator, its life-span length just must be life of generator basically.In order to reach the target with the life-span, each show his special prowess on different directions, is doing effort separately for domestic carbon brush industry.But carbon brush is except life problems, and the important task of derived current is being born in main it, all can have influence on size of current to its any change, influences energy output and electric current quality.Both are mutual restriction often, and along with the raising of automotive performance, the requirement of energy output and electric current quality aspect is also improving constantly.More satisfactory solution motor performance and carbon brush life-span, this was a carbon brush manufacturing enterprise problem demanding prompt solution to contradiction.
Summary of the invention
The objective of the invention is to solve the problem of the existing wearing and tearing of automobile engine starting carbon brush for electric machine and conductivity mutual restriction in the prior art, a kind of automobile engine starting carbon brush for electric machine and production method thereof are provided.The present invention designs a kind of automobile engine starting carbon brush for electric machine; It is characterized in that forming by weight percentage: mixing graphite powder 30-60% by following constituent; Copper powder 35-65%, two selenizing niobiums 3-6%, described mixing graphite powder is made up of following constituent by weight percentage: graphite powder 70-80%; Pitch 5-15%, phenolic resins 10-20%.2, by the described a kind of automobile engine starting carbon brush for electric machine preparation method of claim 1; It is characterized in that forming: prepare mixing graphite powder earlier by the following step; Graphite powder adds pitch and under 220 degree, mixes; Slowly cool to 100 degree and add phenolic resins when following, under 90 degree conditions, mix then, abrasive dust afterwards to be dried becomes mixing graphite powder for use; Copper powder, two selenizing niobiums are joined mixing graphite powder with dry powder form, in dry mixer, mix, compacting automobile engine starting carbon brush for electric machine.Advantage of the present invention is to adopt resin modified pitch as binding agent, has had the advantage of resin and two kinds of binding agents of pitch concurrently, has not only improved the intensity of carbon brush but also do not make carbon brush really up to the mark, has used two selenizing niobiums to be lubricant, efficiently solves the carbon brush lubrication problem.
Below in conjunction with instance the present invention is made detailed operation instruction.
