Description
Technical field
The present invention relates to tyre technologies, and in particular to a kind of light-colour rubber composition for scissor tire.
Background technique
Common tire is usually black, and appearance is single, it is difficult to meet diversified decoration demand.To obtain other colors
Tire, need using light sizing material, and existing light sizing material usually requires to add more light filler, as titanium dioxide into
Row toning, reduces the mechanical property and service life of tire.In addition, light sizing material is more demanding to anti-aging agent, and black wheel
A series of anti-aging agent of high stabilities such as common amines antioxidants is easy to change in use for some time in tire；Others are anti-old
Often anti-aging effect is weaker when agent is used alone, it is difficult to guarantee the color stability of light tire.
Therefore, even lack a kind of good mechanical property, long service life and light color tyre rubber group not easy to change
Close object.
Summary of the invention
In view of the above problems in the prior art, the present invention provides a kind of light-colour rubber composition for scissor tire, tool
There are preferable intensity and toughness, preferable hardness and higher color stability, is used for a long time not easy to change.
To achieve the above object, the invention adopts the following technical scheme:
A kind of light-colour rubber composition for scissor tire, including following components:
120~140 parts by weight of standard rubber, 120~140 parts by weight of smoke sheet rubber, 10~20 parts by weight of zinc oxide, stearic acid 4
~10 parts by weight, 100~150 parts by weight of white carbon black, 10~15 parts by weight of silane coupling agent, 3~5 parts by weight of sulphur, promotor 6
~12 parts by weight, 8~15 parts by weight of reinforcing agent, 5~10 parts by weight of anti-aging agent, 15~20 parts by weight of white oil, 4~6 weight of titanium dioxide
Measure part, 0.3~0.5 parts by weight of carbon black.
Preferably, the weight ratio of the standard rubber and smoke sheet rubber is 1:1, and the smoke sheet rubber is import smoke sheet rubber.
Preferably, the promotor uses altax and accelerant CZ by weight for the compounding of 5~8:2~4.
Preferably, the reinforcing agent is LS-506 resin.
Preferably, the anti-aging agent is antioxidant MB.
Preferably, the silane coupling agent is double-[γ-(triethoxysilicane) propyl] tetrasulfide.
Preferably, the titanium dioxide is the rutile type titanium white of chloridising preparation.
Beneficial effects of the present invention:
(1) activation arranged in pairs or groups using standard rubber and smoke sheet rubber, and constituted using zinc oxide, stearic acid, sulphur and promotor
Cross-linking system improves the tensile strength and tearing strength of sizing material；
(2) white oil is for improving hardness and color stability；White carbon black and reinforcing agent are arranged in pairs or groups, for improving tearing strength,
When especially with LS-506 resin as reinforcing agent, effect is best；In addition, LS-506 resin can also be with white oil and anti-aging agent
MB generates synergistic effect, significantly improves the color stability of sizing；
(3) titanium dioxide additive amount is few, smaller on performance influence, and intensity and hardness are high after gained rubber composition compounding, tough
Property it is good, be used for a long time not easy to change, while because colour system is shallow, can also add appropriate color masterbatch system according to color demand in practical application
At the tire of various colors, meet diversified decoration demand.
Specific embodiment
The present invention will be described in detail With reference to embodiment.It should be understood that described herein
Specific embodiment is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
Light-colour rubber composition for scissor tire of the invention, including component: 120~140 parts by weight of standard rubber, cigarette
120~140 parts by weight of piece glue, 10~20 parts by weight of zinc oxide, 4~10 parts by weight of stearic acid, 100~150 parts by weight of white carbon black,
10~15 parts by weight of silane coupling agent, 3~5 parts by weight of sulphur, 6~12 parts by weight of promotor, 8~15 parts by weight of reinforcing agent are prevented
Old 5~10 parts by weight of agent, 15~20 parts by weight of white oil, 4~6 parts by weight of titanium dioxide, 0.3~0.5 parts by weight of carbon black.
Inventors have found that using the standard rubber of specific proportion and smoke sheet rubber as base-material, and utilize zinc oxide, stearic acid, sulphur
With promotor as activation cross-linking system, be conducive to improve tensile strength and tearing strength；The promotor is preferably using promotion
Agent DM and accelerant CZ are that 5~8:2~4 is compounded by weight.In addition, white carbon black and reinforcing agent are arranged in pairs or groups, tearing strength can be improved,
White oil is then used to improve hardness and color stability.Colour system is shallow after said components compounding, while because titanium dioxide additive amount is few, to property
Energy influence is smaller, can guarantee preferable intensity, hardness, toughness and color stability.In practical applications, one can be also added on demand
The tire of corresponding color is made in quantitative color masterbatch, meets diversified decoration demand.
In said components, smoke sheet rubber excellent combination property, but higher cost, commonly used in the production of aviation rubber product；
Standard rubber is from a wealth of sources, and cost is relatively low, and the two collocation can make full use of respective advantage, meets scissor tire to the side such as wearability
The performance requirement in face and the industrial applications demand of low cost.Preferable scheme is that the weight ratio of control standard rubber and smoke sheet rubber
For 1:1, the import smoke sheet rubber more preferably produced using Malaysia.
Since smoke sheet rubber color is deeper, for the sizing material for obtaining light color, simplest way is a large amount of titanium dioxide of addition, but
It is the mechanical property that titanium dioxide additive amount can excessively reduce tire.Inventor it is found through experiment that, using the white carbon black of specific proportion,
White oil and reinforcing agent collocation, can obtain the light sizing material haveing excellent performance on the basis of lower titanium dioxide additive amount.The reinforcement
Agent is preferably LS-506 resin, and LS-506 resin is a kind of tackifying resin well known in the art, is mainly used for reinforcing rubber.At this
In invention, LS-506 resin not only has good chemiluminescence with white carbon black, but also can act synergistically on glue with white oil
Expect the improvement of color stability.
The anti-aging agent is preferably antioxidant MB, is arranged in pairs or groups with white oil and LS-506 resin, can effectively prevent sizing material discoloration.
The silane coupling agent preferably double-[γ-(triethoxysilicane) propyl] tetrasulfide, except as coupling agent with
Outside, moreover it is possible to arrange in pairs or groups with activation cross-linking system, white carbon black and reinforcing agent, there is activation and reinforcing effect.
The titanium dioxide is preferably the rutile type titanium white of chloridising preparation, and covering power is high, and anti-decolourization is excellent,
Tire metachromatism can be mitigated significantly.
The carbon black is added preferably in the form of black masterbatch, in order to measure, and improves the dispersing uniformity of carbon black.
It is furthermore preferred that light-colour rubber composition of the invention includes component:
130 parts by weight of standard rubber, 130 parts by weight of import smoke sheet rubber, 10~18 parts by weight of zinc oxide, 4~7 weight of stearic acid
Part, 120~150 parts by weight of white carbon black, 11~13 parts by weight of silane coupling agent, 4~5 parts by weight of sulphur, 5~8 weight of altax
Measure part, 2~4 parts by weight of accelerant CZ, 8~12 parts by weight of LS-506 resin, 5~8 parts by weight of antioxidant MB, white oil 16~18
Parts by weight, 4~6 parts by weight of titanium dioxide, 0.3~0.5 parts by weight of carbon black.
