Abstract
The invention discloses a tire rubber material with excellent cooling performance. The tire rubber material is characterized in that in the formula, full-natural rubber is combined with a semi-effective vulcanization system and a reinforcing system, wherein the semi-effective vulcanization system comprises the following commixed components in parts by weight: (1) 2.3-2.8 parts of sulfur and (b) 0.5-0.8 part of an aminodithioformate accelerator; the reinforcing system comprises the following commixed components in parts by weight: (a) 25-35 parts of carbon black, (b) 15-25 parts of white carbon black and (c) 2.2-2.6 parts of a pure-silane coupling agent Si-69.
Description
Technical field
The present invention relates to giant all-steel radial engineering tyre production technical field, be specifically related to a kind of tyre stock of superior heat radiation performance.
Background technology
Giant all-steel radial engineering tyre is the tire of the transported material vehicles such as place mining such as large-scale mine.Section due to giant tyre tread portion comprises tyre surface, tread slab base, belt, carcass and transition layer and air retaining wall, and whole section thickness size is large, belongs to the pole thick product in rubber item.
Giant tyre working conditions is quite severe, and charge capacity is large especially, and tyre section each several part size is large, in tire used process inside tires particularly tread base sizing material high heat-dissipating not easily shed, greatly reduce Using Life of Tyre.Experience shows, the length in giant tyre work-ing life, is decided by the height of the inner heat-dissipating of tyre surface, base portion sizing material to a great extent.How to design the tread base sizing compound formula that heat-dissipating is lower, just can increase substantially the work-ing life of giant tyre.
At present, giant embryo tread base sizing compound formula, the carbon black that many use heat-dissipatings are higher and thermo-labile aging traditional sulfur cross-linking system.Carbon black uses the sizing material heat-dissipating of full black-reinforced fast especially in tire running process.Tradition sulfur cross-linking system (2.5 parts of sulphur, 0.6 part of dithiocarbamatetype accelerator), the monosulfidic bond of chemistry and Heat stability is good is few, mostly the cross-link bond generated is chemical stability and the poor cystine linkage of thermostability and polysulfidic bond, sizing material reversion resistance is poor, and physicals lowers obvious especially.The sizing material heat-dissipating of this formulating of recipe is high, greatly reduces Using Life of Tyre.
Summary of the invention
The technical problem to be solved in the present invention is for the short shortcoming of the poor Using Life of Tyre caused of existing tire heat dispersion, provides a kind of tyre stock of superior heat radiation performance.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of tyre stock of superior heat radiation performance, All Pure Nature rubber is adopted to be equipped with SE curing system and reinforcement system in tyre stock formula, this SE curing system includes by the blended component of following parts by weight: a kind of tyre stock of superior heat radiation performance, it is characterized in that, All Pure Nature rubber is adopted to be equipped with SE curing system and reinforcement system in its formula, this SE curing system includes by the blended component of following parts by weight: (a) sulphur 2.3 ~ 2.8 parts of (b) dithiocarbamatetype accelerators 0.5 ~ 0.8 part, this reinforcement system adopts carbon black/white carbon black/silane coupling agent reinforcement system, and this reinforcement system includes by the blended component of following parts by weight: (a) carbon black 25 ~ 35 parts of (b) white carbon blacks 15 ~ 25 parts of (c) pure silane coupling agent Si-69 2.2 ~ 2.6 parts.
Beneficial effect:
The present invention devises has that toughness is high, heat-dissipating is low and good springiness, the tyre surface of high strength, base portion sizing material are newly filled a prescription.The systems such as the new formula rubber after improvement and anti-aging and original formulation roughly constant, mainly larger adjustment has been carried out to sizing material reinforcement system and vulcanization system.The δ value of the silica compound of laboratory test is lower than the δ value of carbon black sizing material, can find out that the sizing material heat-dissipating using full black-reinforced is fast especially, and use the sizing material heat-dissipating of white carbon black reinforcement just very low.New formula heat-dissipating after improvement reduces 40% than the formula before improvement.Use silane coupling agent Si-69 to carry out modification to white carbon black, solve the affinity of white carbon black and sizing material, improve the processing characteristics of sizing material.The physical and mechanical properties such as stress at definite elongation, tensile strength, tear strength of sizing material can be made to improve simultaneously, play and prevent the effect of sizing material thermal ageing.Adopt SE curing system, heat-resisting singly-bound is more, heat labile cystine linkage and polysulfidic bond less, the physicals of sizing material still keeps better when sizing material heat-dissipating is higher.
