Abstract
The invention relates to a rubber material used in vehicle parts, in particular to a rubber diaphragm material for a vehicle brake system. The material comprises the following components in part by weight: 80 to 110 parts of nitrile rubber, 3 to 8 parts of zinc oxide, 0.5 to 1.5 parts of stearic acid, 0.2 to 1.0 part of antioxidant 0D, 0.2 to 1.0 part of antioxidant 0DA, 0.5 to 2.0 parts of DCP, 0.3 to 1.0 part of sulfur, 30 to 100 parts of carbon black and 15 to 50 part of plasticizer. Compared with the conventional diaphragm material for the vehicle brake system, the rubber diaphragm material has the advantages of greatly prolonging the fatigue life, and meeting low temperature performance requirement, along with small deformation and high corrosion-resistant capacity.
Description
Technical field
The present invention relates to the elastomeric material that uses in a kind of vehicle part, specifically is a kind of rubber diaphragm material for vehicle brake system.
Background technology
Brake system of rail vehicle starts from the sixties with the development of air control valve 103/104 valve, identifies in 1978 and promotes.This valve adopts the rubber diaphragm structure, replaces metallic piston and metal packing in the old type T-valve, can guarantee resistance to air loss, improves sensitivity, reduce the metal grinding workload, and maintenance is convenient.Existing rubber diaphragm adopts the tree elastomer manufacturing usually, and winter hardiness is fair, but oil-proofness is poor, and in the life-span short (only 2 years), this becomes one of shortcoming of 103/104 valve.In use, 103/104 valve often has diaphragm to be braked the mist of oil etch that cylinder fat and reservoir bring into and the corrosive phenomenon takes place; Since 120 valves were promoted, problems such as the distortion of diaphragm burn into, perforation were also reflected at the utilization scene in a large number.
Summary of the invention
Technical problem to be solved by this invention is, provides that a kind of corrosion resistance is strong, the rubber diaphragm material for vehicle brake system of long service life.
The composition of rubber diaphragm material for vehicle brake system of the present invention and parts by weight are: 80～110 parts of paracrils, 3～8 parts in zinc oxide, 0.5～1.5 part of Triple Pressed Stearic Acid; 0.2～1.0 part of anti-aging agent 0D; 0.2～1.0 part of anti-aging agent 0DA, DCP0.5～2.0 part, 0.3～1.0 part in sulphur; 30～100 parts of carbon blacks, 15～50 parts in softening agent.
The use for brake system diaphragm material that the present invention is traditional relatively, improve its fatigue lifetime greatly, and material deformation is little simultaneously, corrosion resistance strong, can satisfy the low-temperature performance requirement.
Embodiment
The embodiment of the prescription of material of the present invention is following:
Embodiment one: 85 parts of paracrils, 6 parts in zinc oxide, 1 part of Triple Pressed Stearic Acid, 1.0 parts of anti-aging agent 0D, 0.5 part of anti-aging agent 0DA, 1.5 parts of DCP (technical grade), 0.5 part in sulphur, 90 parts of carbon blacks, softening agent BIAMDA30 part.
Embodiment two: 100 parts of paracrils, 5 parts in zinc oxide, 0.8 part of Triple Pressed Stearic Acid, 0.8 part of anti-aging agent 0D, 0.8 part of anti-aging agent 0DA, 2 parts of DCP (technical grade), 0.3 part in sulphur, 65 parts of carbon blacks, softening agent BIAMBA25 part.
Embodiment three: 100 parts of paracrils, 5 parts in zinc oxide, 1.5 parts of Triple Pressed Stearic Acid, 0.5 part of anti-aging agent 0D (technical grade), 1.0 parts of anti-aging agent 0DA, DCP1.2 part, 0.5 part in sulphur, 45 parts of carbon blacks, softening agent BIAMBA20 part.
The production technique of above-mentioned materials is following:
One, equipment: two roller mill XK-160 or other, rubber strainer 250 model, electronic weighbridge (maximum capacity 100Kg, sensibility reciprocal 5g), electronic platform balance (maximum capacity 10Kg, sensibility reciprocal 1g), electronic balance (maximum capacity 500g, sensibility reciprocal 0.01g).
Two, instrument: instruments such as charging tray, stroke material cutter, charging box.
Three, weighing: take by weighing each component by proportioning, be respectively charged in the charging tray, weigh is not more than the electronic balance weighing of using of 500g, and 500g is above use the electronic platform scale weighing, uses the electronic weighbridge weighing more than the 10Kg.
Four, plasticate: the paracril rubber that weighs up is put in the mill under pony roll square thin logical for 3～5 times.
Five, mixing: mill mixing, step is following:
1. the rubber of plasticating is thin leading to 3～5 times below 0.3mm;
2. adjustment roller square to 2～2.5mm adds zinc oxide, Triple Pressed Stearic Acid, and after eating powder and finishing, cutter turns refining twice;
3. adding anti-aging agent, after eating powder and finishing, cutter turns refining twice;
4. adding softening agent, after eating powder and finishing, cutter turns refining eight times;
5. adding carbon black, after eating powder and finishing, cutter turns refining eight times;
6. adding vulcanizing agent, after eating powder and finishing, cutter turns refining three times;
7. thin logical triangle bag was 5～6 times after clot mixed 12 times;
8. after descending sheet to be cooled to below 35 degree, filter glue is gone up sheet cooling under the mill behind the filter glue.
The above embodiment of the present invention can reach following index through detecting:
1, material fatigue life is increased to (former tree elastomer is 120,000 times) 250,000 times.
2, the material lipid of anti-hydro-check quantitative changeization 0%～15% (the former tree elastomer lipid of anti-hydro-check quantitative changeization 40%～60%).
3, material compression set≤30% (former tree elastomer compression set 50%).
4, the low temperature requirement is satisfied in the cold-resistant coefficient of material (50 ℃) >=0.4.
