Description
Technical field
The invention belongs to high-speed railway brake unit is and in particular to a kind of speed per hour 300km/h high-speed railway braking synthesizes
Brake lining.
Background technology
2008, operation opened by first high-speed railway of China；In the end of the year 2015, it is public that China's high ferro operation mileage surpasses 1.9 ten thousand
In, rank first in the world.High-speed railway changes the Transportation Pattern of China, and the life giving people brings more convenient and frightened
Happiness.At present, the brake pad that China Express Railway adopts uses metal sintering high speed brake lining substantially, and mostly import.
With the development of China's economic, reducing energy consumption, reduce discharge, improving safety becomes the main flow of economic development, I
The developing rapidly of state's high ferro technology, the braking technology of rolling stock is equally faced with great innovation.For reaching energy-saving and emission-reduction
Target, needs to use multiple energy saving technology, wherein light-weight design is the most easily to realize in practice in engineering.By light weight
Change technology with the maximization realizing economic benefit.By the design of " lightweight ", rolling stock is improving power and safety
Property, reduce discharge etc. aspect will have outstanding behaviours, so aluminium alloy make brake disc a few years from now on will be widely used in locomotive
On.Former, though aluminum is light, hardness and fusing point low it is impossible to obtain good braking ability, so, recognized always in the past
For being not suitable as brake material.But, the innovation with technology and development, this problem has been resolved, in aluminium alloy
Middle admixture ceramic particle makes brake disc obtain good wearability, and lightweight, and its prominent advantage is, with conventional grey mouth casting
Iron Moving plate (for speed to 200 km/h) compares weight saving 50% with spheroidal graphite cast-iron brake disc (for higher speed),
It is apparent that the light-duty disc-brake of aluminium alloy is for the purpose of mitigating the vehicle unsprung weight having baneful influence to rail；Braking
The lightweight of disk can be greatly lowered train unsprung mass, and this impacts, reduce noise, improve ride comfort all to mitigating track
There is remarkable result.
For realizing the high speed of rail truck, the weight mitigating vehicle is very necessary.Wherein, in order to reduce vehicle to rail
The impact of the ground installations such as road, bridge, reduces the unsprung weight of the bogies such as axle weight, vehicle, axletree, axle box, gear-box especially
Important.Brake disc is a part for unsprung weight, bullet train speed is higher, braking when the heat produced by friction that causes
Bigger, so the brake lining that exploitation is matched with aluminium alloy brake disc is very important.
Because aluminium alloy brake disc will be widely used in High Speed Railway Vehicle, Composition brake shoes newly developed must have
Coefficient is examined in higher rubbing, less abrasion, more excellent thermal diffusivity and character of heat-fading.The braking of the existing High Speed Railway Trains of China
Using metal sintering brake lining system, ratio is great, and energy consumption is big, and hardness is high, easily produces noise, be also easy to hinder wheel during braking more；
The brake lining that existing Composition brake shoes manufacturer of China produces generally is suitable for cast iron brake disk, as installing aluminium alloy brake disc
High Speed Railway Vehicle, rubs and examines coefficient, wear rate, thermal diffusivity, character of heat-fading etc. and do not reach technical requirement, there is also serious
Potential safety hazard, so for the design concept responding " lightweight ", my company develops the brake lining being applied to aluminium alloy brake disc.
Content of the invention
The problem existing for prior art, the present invention is intended to provide a kind of light specific gravity, hardness is low, to wheel no heat injury can
For composite brake shoe on the bullet train of speed per hour 300km/h.
The technical solution used in the present invention is: speed per hour 300km/h high-speed railway braking composite brake shoe, and its composition inclusion rubs
Rub body and steel back, described friction piece material composition includes butadiene rubber, high temperature resistant boron modification resin, aramid fiber, graphite, liquid
Quenching medium, high temperature resistant filler, carbon carbon fiber, sulfur, zinc oxide, vulcanization accelerator, age resistor, white carbon black, stearic acid and ferrum oxide
Palm fibre；The percentage by weight of each component is: butadiene rubber 13-15%, high temperature resistant boron modification resin 9%-11%, aramid fiber 8%-10%,
Graphite 8%-12%, liquid hardening agent 5%-9%, high temperature resistant filler 14%-18%, carbon carbon fiber 18%-23%, sulfur 0.5%-1.0%, oxygen
Change zinc 0.5%-1.0%, vulcanization accelerator 0.4%-1.0%, age resistor 0.3%-0.8%, white carbon black 1.5%-2.5%, stearic acid 0.3%-
0.8%, iron oxide brown 4.0%-5.0%.
Described steel back material is q235, and steel back is formed by the thick q235 steel plate compacting of 4.5mm.
Described speed per hour 300km/h high-speed railway braking composite brake shoe, its preparation method is:
1) butadiene rubber divides two sections of mills, 40 DEG C -45 DEG C of first paragraph roller temperature, roll spacing 2mm-3mm, first plus rubber, adds oxidation
Zinc, age resistor, white carbon black, slice is parked；35 DEG C -40 DEG C of second segment roller temperature, roll spacing 3mm-4mm, first plus one section of glue, cutter is mixed,
Plus sulfur, after being all mixed into, cutter is thin logical；
2) by 1) glue that obtains and remaining component of friction piece all add banbury pressurization mixing, temperature control at 140 DEG C -50 DEG C,
Strength mixes, and parks and is cooled to room temperature, obtains compound；
3) by 2) be obtained compound mould be compressed in steel back, press pressure be 18mpa, cold pressing, do not heat, obtain molding
Semi-finished product；
4) by 3) be obtained compressing semi-finished product in an oven adopt hot air circulation electric-heating heat treatment 48h, front 20h temperature by
Edge up height, until maximum heat treatment temperature reaches 350 DEG C, rear 28h keeps 350 DEG C of heat treatment temperature, as shown in table 1, allows all
Raw material fully reacts it is ensured that thoroughly well-done, prepared composite brake shoe., by the way of Fractional Heat-treatment, temperature is gradually for heat treatment
Raise it is ensured that brake lining surface is consistent with its internal temperature, synthetic material degree of ripeness of trying hard to keep is consistent, using hot air circulation electrical heating both
Can guarantee that effectively carrying out of heat treatment.
Compared with prior art, the invention has the advantages that:
1st, the organic synthesiss brake lining light specific gravity of my company's exploitation, hardness is low, to wheel no heat injury；Have in terms of energy-conserving and environment-protective
Great raising；
2nd, the main of friction piece of the present invention is made up of macromolecular material, on the basis of meeting brake request, also mitigates locomotive
Vehicle weight, is just catering to the design concept of national " lightweight "；
3rd, adopt high temperature resistant boron modified phenolic resin in friction piece material composition of the present invention, boron modified phenolic resin has more preferably
Resistance to elevated temperatures, it is to avoid in traditional handicraft, the modulus caused by friction material with pure phenolic resin as matrix is too high, strong
Spend the problem that low, noise is big, heat decomposition temperature is low, the residual physical performance of decomposition of frictional layer is unstable, therefore boron modification resin is
It is suitable for the optimal choice of the technological requirement of this Composition brake shoes；
4th, adopt butadiene rubber in friction piece material composition of the present invention, butadiene rubber, compared with natural rubber and butadiene-styrene rubber, has
