Abstract
The invention discloses a formula for tread rubber of a tire which is suitable for various pavement conditions. The formula is formed by adoption of natural rubber as a main material, cis-1, 4-polybutadiene rubber, intermediate and ultra abrasion resistant carbon black, high-dispersity white carbon black, a silane coupling agent, an anti-cracking resin and a heat stabilizer as main auxiliary materials, and zinc oxide, a stearic acid, a para-phenylene diamine anti-ageing agent, a ketoamine anti-ageing agent, insoluble sulfur, a sulfenamide type accelerator as auxiliary materials. The formula has the advantages that: the tread rubber is made to have the advantages of high tensile strength, high tear strength, high stress at definite elongation, good puncture resistance, low dynamic heat generation, good thermal stability, good abrasion resistance and good flexure and crack resistance. When the tread rubber is used for the tire, the tire is suitable for various pavement conditions, not only is suitable for highway pavements and high-speed conditions but also is suitable for off-highway conditions such as soil pavements, sand and stone pavements and so on, and has good abrasion resistance and long service life.
Description
Technical field
The present invention relates to tire tread glue, specifically is a kind of tire tread glue formulation that can adapt to various pavement conditions uses.
Background technology
A kind of vehicle of special purpose except needs are run at high speed on highway, also need travel on earth, gravel road surface sometimes.Existing tire tread glue can only adapt to a kind of working conditions in Highway Conditions or earth, the gravel road surface condition, working conditions that can not the above two kinds of road surfaces of simultaneous adaptation.
Summary of the invention
The present invention seeks to disclose and a kind ofly can adapt to the tire tread glue formulation that various pavement conditions use, this prescription tread rubber has tensile strength height, tear strength height, higher, the anti-puncture performance of stress at definite elongation is good, dynamic heat build up is low, Heat stability is good, wear resisting property is good and resist and deflect the good advantage of performance that chaps.The tire that uses this tread mix is good at earth, anti-puncture when gravel road surface uses, cracking resistance mouth performance, long service life.When Highway Conditions was used, tire internal temperature was low, high speed performance good.
For achieving the above object, the present invention adopts following technical scheme:
Prescription is main material with the natural rubber, with cis-1,4-polybutadiene rubber, intermediate super abrasion furnace black, polymolecularity white carbon black, silane coupling agent, cracking resistance mouth resin, thermo-stabilizer is main auxiliary material, is equipped with zinc oxide, stearic acid, p phenylenediamine type antioxidant, ketoamine class anti-aging agent, insoluble sulfur, sulfenamide type accelerators ratio of adjuvant again and forms.Each component raw material consumption weight part ratio is:
Natural rubber 80～100 thermo-stabilizers 0.5～5
Cis-1,4-polybutadiene rubber 20～0 zinc oxide 3～10
Cracking resistance mouth resin 2～3 stearic acid 1～4
Polymolecularity white carbon black 10～20 p phenylenediamine type antioxidants 1～4
Silane coupling agent 0.5～5 ketoamine class anti-aging agent 1～4
Intermediate super abrasion furnace black 30～40 insoluble sulfurs 1～4
Sulfenamide type accelerators 1～3.
Wherein: natural rubber is 1
#Smoke sheet rubber or 20
#Standard glue, cis-1,4-polybutadiene rubber be BR9000, cracking resistance mouth resin be AD-1600, polymolecularity white carbon black be Jc sil 150 or Ultra sil 7000GR, silane coupling agent be KH-845-4, intermediate super abrasion furnace black be the high structure intermediate super abrasion furnace black of novel process N234, thermo-stabilizer be HS-80, p phenylenediamine type antioxidant be 4020 or 4010NA, ketoamine class anti-aging agent be that RD, insoluble sulfur are that IS-60 or IS-90, sulfenamide type accelerators are NS or NOBS.
Natural rubber described in the prescription has the advantages that to tear performance height, good combination property by force; Cis-1,4-polybutadiene rubber has the good advantage of good, the warping strength be full of cracks performance of wear resisting property; Cracking resistance mouth resin adds the tear strength and the tensile yield that can improve in the sizing material after sizing material wears out; The high structure intermediate super abrasion furnace black of novel process has good, the tear strength advantage of higher of the wear resisting property that makes sizing material; The good dispersion property of polymolecularity white carbon black uses with the silane coupling agent collocation, can make sizing material have low, the advantages such as tear strength is high, anti-puncture of the heat of giving birth to; Adding thermo-stabilizer HS-80 in the sizing material can make cross-linked rubber have good thermostability and anti-reversion performance.Based on the performance characteristics of above material,, develop to reach and to adapt to the tire tread glue that Highway Conditions can adapt to non-Highway Conditions again by scientific matching.
This formulated rubber material performance after tested, its performance range such as following table:
| Project | Unit | Performance range |
| Tensile strength | MPa | 24.0～28.0 |
| Tensile yield | ％ | 500～600 |
| Tear strength | kN/m | 130～160 |
| Tear strength after the 100 ℃ * 24h hot air aging | kN/m | 110～150 |
| 300% stress at definite elongation | MPa | 10.0～15.0 |
| Compression fatigue is given birth to heat | ℃/25min | 16～25 |
| Vulkameter torque curve velocity of variation (170 ℃ * 60min) | ％ | -15～-5 |
| Elongation change rate after the 100 ℃ * 24h hot air aging | ％ | -20～-10 |
| Wear loss (Akron) | cm 3/1.61km | 0.1～0.2 |
| Deflect be full of cracks rank (300,000 times) | Level | 0～6 |
The invention has the advantages that: prescription is by adding cracking resistance mouth resin, polymolecularity white carbon black, the high structure intermediate super abrasion furnace black of novel process and thermo-stabilizer, make tread mix have good anti-puncture performance, and have higher stress at definite elongation, low-heat-generation and thermostability, a good abrasion resistance, the tire that uses this tread rubber is at earth, anti-puncture was functional when gravel road surface travelled, and gives birth to when Highway Conditions is used that heat is low, Heat stability is good, good, the long service life of high speed performance.
