Abstract
The invention relates to a touch power transmission composite and a manufacturing method thereof. The composite comprises 33-38 parts of chopped fibers, 52-58 parts of coke or graphite particles and 8-12 parts of coke adhesives. The manufacturing method includes steps of mixing the chopped fibers, the coke or graphite particles and the coke adhesives proportionally and then stirring mixture in a stirrer, heating for 30-60 minutes according to quantity of the materials at the temperature of 200 DEG C, forming and pressing by forming equipment, roasting the pressed and formed materials in roasting equipment and compacting and cyclically carbonizing the materials to obtain the composite. The composite is antioxidant, wear resistant, anti-fatigue, anti-corrosion, creep resistant and light in weight, resistance of the composite is smaller than that of any metal materials, and no arc light is generated when electric vehicles run at high speed, so that the composite is more suitable for being used as contact materials of electric switches.
Description
Technical field
The present invention relates to the research and development field of composite material, particularly relate to a kind of transmission of electricity composite material and manufacture method thereof of touching.
Background technology
Electric locomotive, urban transit system electric car etc. all travel by touching electric wire absorption power consumption energy drives, metal cords is erected at power line high aerial by the mode such as electric pole or brandreth, its main purpose is to facilitate vehicle pantograph to be in contact with one another with touching power line, by touching power line, delivery of electrical energy is travelled to vehicle motor generation power drive.
It is not that a simple material touches object with the object that touch power line is in contact with one another that vehicle pantograph touches material.This pantograph that is erected at locomotive ceiling touches material and power line and touches the touch material of going together and need meet following technical requirement: the one, be superior to the resistive performance of copper; The 2nd, wear-resisting wiping, want normalization useful life; The 3rd, in the time touching with transmission of electricity electric wire high speed slide, can not there is arclight, avoid damaging expensive transmission of electricity electric wire.It is that lead alloy is made that traditional pantograph touches material, especially in the time exchanging pantograph touch device direction, because interim power-off contacts reason with power supply, can produce a large amount of arclights, often electric wire is blown or touch material lead alloy and burnt, the electric arc light that vehicle often produces is under steam soaring, not only reduce the useful life of transmission of electricity electric wire and touch material, and to environment, waste a large amount of electric energy, road pedestrian has been shone after eyes by arc light, and in the short time, what does not all see Chu, has larger potential safety hazard.
The more important thing is, existing touch material can not adapt to the needs that travel at a high speed of modern electric locomotive, Urban Light Rail Vehicle, subway completely.At present, the touch device needing touches material still taking import as main, expensive, can not meet the demand of all trades and professions.
The new one that how to found that a kind of security performance is good, rub resistance, resistance are little, is difficult for producing arclight touches transmission of electricity composite material and manufacture method thereof, real one of the current important research and development problem that belongs to.
Summary of the invention
The object of this invention is to provide a kind of anti-oxidant, resistance is little, light weight is wear-resisting, wear rate is little, do not produce arclight, transmission of electricity composite material and manufacture method thereof that security performance is good.
In order to address the above problem, the invention provides a kind of transmission of electricity composite material that touches, comprise chopped strand, the coke of 52-58 weight portion or the tar adhesive of graphite granule and 8-12 weight portion of 33-38 weight portion.
Further, described tar adhesive is tarvia adhesive.
Further, described composite material comprises chopped strand, the coke of 55 weight portions or the tar adhesive of graphite granule and 10 weight portions of 35 weight portions.
The present invention also provides a kind of manufacture method that touches transmission of electricity composite material, comprise the following steps: A, chopped strand, coke or graphite granule are mixed in proportion, then add the abundant mix and blend of tar adhesive, then at 200 DEG C of temperature, heat 30-60 minute, compressing; B, send into roasting apparatus after compressing, roasting 30 hours at 200～300 DEG C, is cooled to temperature and reaches 40 degree and carry out densification technique after following after roasting completes; After C, densification complete, composite material is carried out to carbonization 168-400 hour.
Further, described step B completes afterwards again repeating step B mono-to four time.
Further, described densification technique comprises the following steps: product is put in the container of vacuum-pumping, taked to vacuumize mode, by the indoor vacuum tank negative pressure 11-13 kilogram that is evacuated to, tar adhesive is warming up to 90-100 DEG C, the tar adhesive having heated up is joined in container.
Further, the negative pressure in described vacuum tank is 12 kilograms.
Further, described tar adhesive is tarvia adhesive.
The present invention also provides above-mentioned composite material for touching mobile slide power transmission material and electrical equipment contact point component materials and appliance material.
The use that the present invention is applicable to all touch movements and slides power transmission material and electrical equipment contact point component materials.
Adopt after such design, the present invention at least has the following advantages:
Anti-oxidant, wear-resisting wiping, antifatigue, corrosion-resistant, creep resistant, light weight, resistance is less than any metal material, and vehicle is at the high-speed arc light that all can not produce in service, more outstanding for appliance switch contact material, it can alleviate member overall weight 4/5ths, thereby has improved structure technical performance.Self-lubrication is wear-resisting, and proportion is no more than 1.85～1.9, and moulding process is good, and raw material is easy to get, and source is abundant, is to touch slip optimal material, will increase economic efficiency, and can meet industry industrialization needs for electrical equipment contact material.
Material has the performance of protection against the tide, waterproof, and can reach 0.000011～0.000015 Ω than resistance, and electric conductivity is superior, and this composite material power transmission material will be saved to a large amount of rare platinums for contact power transmission material and appliance switch contact material.
In use can not rupture, changing resistance can the starting the arc yet, in heating process, tensile strength more can strengthen etc., material self-technique index is without any change, suitablely touch electric power and travel and carry power supply to use in operation area relying on, in the time touching material temperature and reach 1350 DEG C, material self performance not only can not decline, and performance can rise at double, this is also the advantageous characteristic that any material can not be compared.
Composite material transmission of electricity power supply touch material is mainly used in electric vehicle and dependence sliding contact power supply travels and vehicle and instrument and the electric component contact material of operation.
