Abstract
The invention provides abrasive ash granules containing composite crystal whiskers and a preparation method of the abrasive ash granules. Formulas used in the method are as follows: abrasive ash, magnetite powder, an adhesive and potassium hexatitanate crystal whiskers. A preparation technology comprises the following steps: evenly mixing raw materials according to the formulas; feeding into a double-roll rubber open mill for smelting, and fusing and plasticizing the raw materials; and finally pulverizing the plasticized materials into granules with grain sizes of 8-20 meshes so as to obtain the product of the invention. The product of the invention can be mixed into a brake block in a proportion of 20%-30%, the production cost of a brake block manufacturer is greatly reduced, economic benefits of the manufacturer are huge, and meanwhile environmental pollution is avoided. Hardness and compactness (density) of a friction plate can be reduced effectively, and stability of high-temperature brake of an automobile is guaranteed, and problems of transfer films, environmental pollution, noises, ash and the like are solved.
Description
Technical field
The present invention relates to the material of friction plate in a kind of automobile brake sheet and its preparation method, particularly a kind of mill ash particle containing composite crystal palpus and its preparation method.
Background technology
Breaking system is one of security system the most important on automobile, and brake facing is the parts that to have suffered in breaking system important, it can directly have influence on the reliability of whole breaking system, breaking system defines friction pair by brake facing and brake flange phase mutual friction, produce braking moment, the kinetic energy of automobile is converted into heat energy, and temperature during braking can rise to 300��400 DEG C.
Conventional brake facing is divided into:
1, semi-metal type, main adopts coarse Steel Wool as the big mixture of reinforced fibers and important frictional coefficient, and major advantage is to adapt to normal operation at relatively high temperatures, but noise is too big, and the wear rate of brake flange is bigger;
2, without asbestos organic type, mainly with glass fibre, aromatic polyester fiber and other fibers as reinforcement material, its performance depends primarily on type and other mixture of fiber, and advantage is that shortcoming is that wear resistance and heat resistance are not strong without the ash fouling that falls, feature that noise is little.
Simultaneously, the innovative point of application novel material is to utilize crystal whisker of hexa potassium titanate in friction process to the reflex action of energy and the generation of transfer film, thus ensure the stability of brake facing frictional coefficient, conventional asbestos friction material just there will be performance degradation phenomenon when 230 DEG C, and crystal whisker of hexa potassium titanate also there will not be performance degradation phenomenon when 350 DEG C, stable frictional behaviour still can be maintained. Noise is the most insoluble problem of all friction materials manufacturers always, crystal whisker of hexa potassium titanate makes it constantly form displacement membrane due to the molecular structure of its material uniqueness, the brake facing being made up of it is not only without high frequency noise, and substantially solve the problem of low frequency noise, potassium hexatitanate stable chemical performance, nontoxic, human security can not be injured, do not pollute the environment.
Having, automobile brake sheet can produce to grind ash in a large number in process of production again, and these mill ashes comprise the dust that ground finish produces and the dust holed and produce. They account for the 10% of raw-material weight, if do not reclaimed, let alone in atmosphere floating, and environmental hazard is very big.Inherently saying, these mill ashes belong to friction materials together, if can be recycled, can reduce production cost for brake facing manufacturer, and bring huge economic benefit.
And the common practice of the mill ash of brake facing manufacturer process at present is, employing cleaning apparatus reclaims and hoards, then buries process. Only a small amount of fractional material factory recycles mill ash in order to regenerative ratio, and not only the rate of recovery is extremely low, but also can affect the performance of brake facing.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, and a kind of mill ash particle containing composite crystal palpus is provided. Solve in brake flat production process the problem of the mill ash that produces how recycling, and provide a kind of composite crystal must using method in formula.
The technical scheme realizing above-mentioned purpose of the present invention is: a kind of mill ash particle containing composite crystal palpus, and it is adopted and is prepared from the following method:
Formula includes: mill ash 55��65 weight parts, magnetite powder 10��20 weight part, sizing agent 9��11 weight part, crystal whisker of hexa potassium titanate 20��25 weight part.
Step of preparation process is as follows:
The first step: the group part and the respective weight part number that contain by material are prepared burden;
2nd step: mixed by raw material, drops into two rod rubber mixing mill and carries out melting, make raw materials melt and plastify, and its roller surface temperature is 50��60 DEG C; Smelting time is 20��30min;
3rd step: become particle diameter to be 8��20 object particles the material disintegrating after plasticizing.
