Phenomenon is shaped using low pressure, and the maximum pressure of compacting controls within 50MPa, reduces press energy consumption, is extended it and is used the longevity
Life, meanwhile, it can satisfy performance required by product under the pressure.Curing process abandoning tradition segmentation heat preservation in the present embodiment
Mode, using stage slow heating, in resin solidification critical stage using slowly heating, the solidification completion stage is rapidly heated,
It is possible to prevente effectively from the inside and outside defect of product.Bonding agent has been carried out at graphitization in non-oxidation calcining kiln in the present embodiment
Reason, can prevent heat fading, so that the coefficient of friction of grinding in use is always maintained at stabilization, it will not be because of resin decomposition
It causes coefficient of friction sharply to decline, improves the usage safety performance of grinding.Change traditional spray painting or leaching in the present embodiment
Modeling mode carries out surfacecti proteon processing to grinding, develops novel antirust antioxidizing paint, the coating is environmentally friendly, improves
The anti-oxidation function for grinding son extends the service life of grinding, to reduce production maintenance cost.
Formula described in the present embodiment step 1 includes the raw material of following parts by weight:
The bonding agent trade mark described in the present embodiment is Carbores P, and carbon left is up to 85% or more, Carbores P
Bonding agent will be converted into C-C combination network in high temperature firing, improve the bond strength of grinding.Boron carbide in the present embodiment
The product that autoxidation obtains includes B2O3, B2O3Fusing point is lower, and beginning fusing point is 445 DEG C, can play reinforcing effect.
Coating described in the present embodiment step 6 includes the raw material of following parts by weight:

Play the role of adjusting melt temperature scope with melting temperature regulator, specifically fluxing agent and melting temperature in the present embodiment
The weight ratio of regulator is 2；The inorganic bonding agent is the mixture of xanthan gum and silica solution, the weight of xanthan gum and silica solution
Than being 1/5.
The application method that sub- coating is ground in the present embodiment step 6, includes the following steps:
S1, formula rate is pressed by low temperature powder, fluxing agent, suspending agent, melting temperature regulator, waterproofing agent and inorganic bonding agent
It is mixed with water, forms the suspension slurry that specific gravity is 1.65, obtain coating；
S2, it carries out grinding sub- solidification, grinding after heat treatment is immersed in coating and keeps 10s, and by it at 145 DEG C
It is dry.
Grinding can steeply rise so that grinding sub- temperature, reach as high as with wheel tread friction in use
1000 DEG C or more, according to above-mentioned application method grinding sublist face uniformly coat a coating, the coating can since 400 DEG C glaze
Change, form the protective film of liquid, oxygen is prevented to contact with grinding, so that playing prevents inorganic bonding agent and carbonaceous material from aoxidizing
Effect.Since the temperature that carbon starts oxidation is 450 DEG C, the beginning fusing point of coating will be controlled near 400 DEG C, and simultaneous grinding exists
Up to 1000 DEG C or more, therefore in the present embodiment, coating will meet between 400~1200 DEG C maximum temperature in use process
For molten condition, protective film is formed in grinding sublist face, to play the anti-oxidation effect of antirust.Low temperature powder is in the present embodiment
Mixture without lead frit, boron glass powder and borax, without the minimum melting temperature of lead frit be 400 DEG C, and boron glass powder with
The melting temperature of borax is 600-650 DEG C, and low temperature powder is by ensureing initial melting temperature, to ensure the cryogenic property of coating, this reality
The low temperature powder that 30 parts by weight are added in example is applied, low temperature powder can not be added excessively, it otherwise may result in the range shorter of melting zone,
The performance of high-temperature region cannot ensure, therefore should rationally control the additional amount of low temperature powder according to the proportion.
Since grinding is that following train is run in an outdoor environment, rain and snow weather is encountered sometimes, and coating is low
145 DEG C of solidifications of temperature, only bond each component by inorganic bonding agent at this time, may result in after coating meets water and dissolve, so in coating
Middle addition waterproofing agent, specifically waterproofing agent is pure-acrylic emulsion in the present embodiment, and pure-acrylic emulsion plays anti-in the sub- preliminary work of grinding
The effect of water, once grinding after by thermosetting protective film, coating forms reliable glaze layer in grinding sublist face, plays permanent
The effect of waterproof improves the service life of grinding.
Grinding son play the role of to traffic safety it is extremely important, in the prior art grinding son can wrap in process of production
To its surface spray paint before dress, to play the anti-oxidation effect of antirust, but spray painting has biggish harm to environment, so
Painting process is intended to setting Environmental-protecting treater, and to reduce the harm to environment, and environmental protection treatment brings biggish be processed into
This.Coating described in the present embodiment is environment-protecting and non-poisonous, can using the coating in grinding sublist wheat flour for one layer of antirust inoxidzable coating
To effectively prevent inorganic bonding agent and carbonaceous material to aoxidize, the service life of grinding is further improved, improves grinding
Service performance.
