Abstract
The invention relates to a kind of high temperature proof braking material with high heat-conductivity and good burn-retarding ability. The high temperature proof fillings are added to the rubber base material and then are processed according to three ways corresponded to three different forms of the rubber base material to get the product. The mentioned high temperature proof material refers to metal powders, metal oxides, metal hydroxide and nonmetal substances or the mixture of the mentioned substances with good heat-conductivity and good burn-retarding ability. On the base of 100 shares of rubber base material, the high temperature fillings are 20-1000 shares. The invention can improve the high temperature proof ability of the breaking material, extend the service time of the braking material, delay the declining time of the material and ensure the safety of the driving vehicles.
Description
Affiliated technical field:
What the present invention relates to is the good a kind of high-temperature resistant braking material of heat conductivility high flame resistance.
Background technology:
Existing brake material, be to be base material with rubber, resin, promotor, Sulfur etc. are solidifying agent, are heat-resisting strongthener with chrysotile asbestos fibre, glass fibre etc., are heat-resisting reinforcing filler with carbon black, potter's clay, Feldspar Powder, barium sulfate, powdered iron ore, Graphite Powder 99, copper wire, drill rod etc.; Mix and stir the direct sulfuration compacting in back through powdery and form brake material; Or form brake material through latex cooperation, preparation, dry postcure compacting; Or form brake material through mixing, soaking paste, rubber, tear tape, winding, moulding, sulfuration compacting.Brake material after the sulfuration passes through operations such as post vulcanization, grinding again, promptly becomes the brake material finished product, is widely used in drag aspects such as vehicle, locomotive.Owing to often produce high temperature during the vehicle brake braking, sometimes can reach 800 ℃ or higher temperature, and rubber substrate with general not anti-this high temperature of resin, be difficult for heat conduction, be easy to burning, therefore, existing product for braking is heat fading and lose its functions of use easily in use.
Summary of the invention:
In order to overcome existing brake material non-refractory, be difficult for heat conduction, be easy to the incendiary deficiency, the invention provides a kind of high-temperature resistant braking material.It improves the brake material resistance to elevated temperatures, prolongs the brake material heat fading time, prolongs the work-ing life of brake material, guarantees the safety that vehicle travels.
The present invention solves the scheme that its technical problem adopts: add high temperature resistant filler in rubber substrate, described high temperature resistant filler is mainly metal-powder, metal oxide, metal hydroxides and the nonmetallic compound that heat conductivility is good, flame retardant properties is good, perhaps their mixture.Process by three kinds of corresponding methods of form then with rubber substrate.
In the rubber substrate consumption is 100 parts, and high temperature resistant amount of filler is 20-1000 part.
Embodiment:
The present invention is described in detail below in conjunction with specific embodiment and principle.
Embodiment 1: be base material with the powdered rubber.
In powdered rubber, remove and add resin, promotor, sulphur, outside chrysotile and other Synergist S-421 95s, add high temperature resistant filler again, it is good that described high temperature resistant filler is mainly heat conductivility, the metal-powder that flame retardant properties is good, metal oxide, metal hydroxides and nonmetallic compound, perhaps their mixture is (as aluminium powder, aluminum oxide, magnesium oxide, antimonous oxide, aluminium hydroxide, magnesium hydroxide, the crystalline state quartz, boric acid, elastic graphite, carborundum, charing boron etc.), in homogenizer, mix, after cooling off, add in the mould, form brake material through the sulfuration compacting.
Brake material after the sulfuration passes through post vulcanization again, and then it is processed as finished product through operations such as grindings.
Key elements such as sulfurized temperature, pressure, time are determined on a case-by-case basis.Must reasonably grasp exhaust number of times and time during sulfuration.
Embodiment 2: be base material with the latex rubbers.
To make the needed various Synergist S-421 95s of brake material in advance, comprise high temperature resistant filler, it is good that described high temperature resistant filler is mainly heat conductivility, the metal-powder that flame retardant properties is good, metal oxide, metal hydroxides and nonmetallic compound, perhaps their mixture, pass through ball mill, the sand mill, colloidal mill, all equipment such as stock pump or common high speed agitator are made aqueous and the pasty state dispersion at a high speed, then with these Synergist S-421 95s, comprise that high temperature resistant filler adds in the latex, make latex and various Synergist S-421 95 again, comprise that high temperature resistant filler mixes in stirred vessel, through compressing tablet, after the drying, form brake material through the sulfuration compacting.
Brake material after the sulfuration passes through post vulcanization again, and then it is processed as finished product through operations such as grindings.
Key elements such as sulfurized temperature, pressure, time are determined on a case-by-case basis.Must reasonably grasp exhaust number of times and time during sulfuration.
Embodiment 3, be base material with untreated rubber.
(1), plasticates.Use machineries such as mill or Banbury mixer, with untreated rubber plasticate, park, standby.
(2), mixing.Use machineries such as mill or Banbury mixer, with other Synergist S-421 95s outside the adding of the untreated rubber after plasticating sulphur, the promotor, add high temperature resistant filler again, described high temperature resistant filler is mainly metal-powder, metal oxide, metal hydroxides and the nonmetallic compound that heat conductivility is good, flame retardant properties is good, perhaps their mixture is mixing evenly, then slice, cool off, park, standby.
(3), add sulphur.Use machineries such as mill, in rubber unvulcanizate, add sulphur and promotor, treat mixing even back slice, cooling, standby.
(4), rubber or soaking paste
Rubber.Use three rollers or four roll-in court of a feudal ruler machines, will add sulphur glue and be laminated with on cloth of soaking resin or rubber cement in advance or fibercord, cool off then, park, standby.
Soaking paste.To add sulphur glue in advance and be cut into little or be ground into fine granularity, in hollander, be mixed into rubber cement, then with cloth or fibercord soaking paste, drying, cooling, standby with gasoline.
(5), tear tape.With cloth after rubber or the soaking paste or fibercord, it is standby to be torn into slat as required.
(6), moulding.It is standby through twining or be pressed into pie that slat is covered glue fiber cloth or fibercord.
(7), one step cure.The work in-process of forming are vulcanized on vulcanizer.Accurately grasp key elements such as curing temperature, pressure time, and exhaust number of times and time, sulfuration is pressed into brake material.
(8), post vulcanization.Brake material behind the one step cure is carried out two sections hot-air vulcanizations through vulcanizing boiler.
(9), grinding.Brake material behind the post vulcanization is carried out ground finish, to requiring to be the brake material finished product.
