Abstract
The invention belongs to the technical field of vehicle flaps, and in particular relates to a reinforced type wear-resisting vehicle flap which comprises the following composition raw materials in parts by weight: 30 parts of natural rubber, 70 parts of natural recycled rubber, 2-6 parts of vulcanization system, 1-4 parts of anti-aging agent, 1-5 parts of plasticizing agent, 10-20 parts of high wear-resisting furnace black, 10-20 parts of middle wear-resisting furnace black and 0-5 parts of high-dispersity white carbon black. The vehicle flap provided by the invention is high in wear-resistance, and has high tearing resistance, low hardness and low heat generation property, and a provided product is excellent in property, long in service life and easy to assemble and disassemble.
Description
Technical field
The invention belongs to automobile-used rim strip technical field, be specifically related to a kind of reinforced wear-resistant wagon rim strip.
Background technology
Automobile-used rim strip is a kind of and the matching used rubber item of inner tube of vehicle tyre cover tire; be mainly used at present cargo vehicle; be arranged on inner tube of vehicle tyre cover tire and metal wheel hub contact site, play the effect of liner and protection inner tube of vehicle tyre cover tire, extend the work-ing life of inner tube of vehicle tyre cover tire.
As can be seen here, automobile-used rim strip needs good wear resistance, resistance to tearing and low-heat-generation performance, and in addition, automobile-used rim strip is loss product, need to repeatedly change, and therefore also needs to keep namely lower hardness of the certain pliability of automobile-used rim strip.
Automobile-used rim strip is rubber item, the various aspects of performance of rubber compounding direct relation product, and formula comprises five large systems:
1) rubber is fertile material;
2) vulcanization system: comprise vulcanizing agent, promotor and activator, for rubber by linear become netted,
Can improve intensity, the stable prod size and dimension of sizing material;
3) reinforcing and filling system: comprise strengthening agent, weighting agent, for improving chemical property, improve process industrial art performance, increase volume, reduce costs;
4) protection system: as anti-aging agent etc.;
5) Plasticising system: increase mobility, reduce compound viscosity, improve processing characteristics, reduce costs.
In prior art, the raw material of this automobile-used rim strip cannot be taken into account high-wearing feature and low-heat-generation and soft simultaneously.
Summary of the invention
The invention provides a kind of reinforced wear-resistant wagon rim strip, in order to solve defect and the deficiency of above-mentioned existence.
For achieving the above object, a kind of reinforced wear-resistant wagon rim strip of the present invention, the weight part of its constitutive material comprises:
High abrasion furnace black(HAF), such as N330 is the carbon black that a kind of reinforcing property is good, can be given the tensile strength that automobile-used rim strip is higher, tear resistance, and wear resistance and elasticity, apply very extensively, but its wear resisting property is still slightly inadequate for automobile-used rim strip;
Medium super abrasion furnace black, such as N220 is high reinforcement shape furnace treated black, is compared with N330 carbon black, and the wear resistance that contains the automobile-used rim strip of N220 carbon black wants high by 10 ~ 20%, but heat-dissipating and hardness are higher;
In order to reduce the heat-dissipating of rim strip, need to adopt the white carbon black that heat-dissipating is low, but the specific surface area of white carbon black is tending towards greatly Second Aggregation, in addition in air, memory absorbs moisture, cause between hydroxyl and easily produce very strong hydrogen bond association, further improved intergranular cohesive force, so white carbon black is mixing more difficult, and when volume coordinates, also easily make sizing material sclerosis.And replace after common white carbon black with polymolecularity white carbon black, tensile strength, the tear strength of automobile-used rim strip increase, and heat-dissipating and also obviously reduction of abrasion;
Single reinforced filling cannot be taken into account numerous desirable physical and chemical performances simultaneously;
Further, in described vulcanization system, sulphur is common SULPHUR POWDER, oil-filled common SULPHUR POWDER or insoluble sulfur, and the promotor in vulcanization system is accelerator CBS or accelerator NS;
Further, described raw material also comprises 0.5 ~ 1 part of anti-recovery agent in forming;
Further, described high wear-resistant carbon black is selected from one or more in N375, N330, N351;
Further, described medium super abrasion furnace black is selected from one or more in N219, N220, N231;
Further, described softening agent is that pentachlorothiophenol class softening agent or main component are the environment-friendly plasticizer of 2,2 '-dibenzoyl amido Diphenyl disulfide compound (DBO).
A kind of reinforced wear-resistant wagon provided by the invention has been taken into account high abrasion, resistance to tearing and soft, low-heat-generation with rim strip, and the product performance that provide are good, greatly extends work-ing life and is convenient to dismounting.
Embodiment
Below in conjunction with embodiment, further set forth the present invention.Should be understood that these embodiment are only not used in and limit the scope of the invention for the present invention is described.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after having read the content of the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1:
Reinforced wear-resistant wagon is as follows with the feed composition of rim strip:
30 parts of TSR-20 standard particle rubber virgin rubbers, 70 parts of natural reclaimed rubbers, 1 part, sulphur, 2 parts of accelerator CBSs, 0.8 part of anti-recovery agent TYC0900,2 parts of anti-aging agent 6PPD, 4 parts, pentachlorothiophenol class softening agent, 20 parts of high abrasion furnace carbon black N330s, 15 parts of medium super abrasion furnace black N220,3 parts of polymolecularity white carbon blacks.
Above-mentioned raw materials formula adopts the method for traditional automobile-used rim strip of preparation, specifically comprises the following steps: batching, mixing, fast inspection, feed back, extrude, fixed length, weighing, joint, sulfuration, check, packing warehouse-in.
