Description
Technical field
The present invention relates to a kind of rubber with thermal ageing resistant performance, belong to rubber materials.
Background technology
When rubber is taken on alternative cycle stress or strain, caused local structure changes and the growth process of subsurface defect, is called the fatigue of rubber.Under dynamic tensile, compression, distortion and shearing action, the performance of rubber item and structure can produce and change or damage, and this is so-called tired breaking-up.It reduces the mechanical property of material, and finally causes be full of cracks or fracture completely.The tired essence of rubber is that aging presentation occurs the stressed and hot used time rubber of doing, and has covered flexing fatigue and aging fatigue.It is a lot of to there is tired condition in rubber, and analogy is extended or compression; Periodic External Force Acting etc.Fatigue-resisting rubber we daily life and industrial production in be widely used, there is high practical value.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of rubber with thermal ageing resistant performance.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of rubber with thermal ageing resistant performance, this rubber with thermal ageing resistant performance comprises the component of following portions by weight: natural rubber 80-220 part, hydrogenated nitrile-butadiene rubber 50-220 part, nano zine oxide 3-10 part, sodium stearate 2-4 part, carbon black N10015-65 part, tenderizer 5-12 part, strengthening powder 5-15 part, sulphur 5-10 part, anti-aging agent 2-5 part, calcium carbonate 2-8 part, tackifier 2-6 part, naphthenic oil 2-5 part, white carbon black 2-5 part, scorch retarder 2-5 part, dibutyl phthalate 2-4 part, zinc diethyldithiocarbamate 2-4 part, 2-thiol group tetrahydroglyoxaline 2-4 part, softening agent 2-10 part.

According to antifatigue physical disturbance, can utilize tenderizer or softening agent control fatigue of materials weathering process, from the power-chemical theory of fatigue aging, add tenderizer and softening agent can make rubber molecule mobility strengthen, stress relaxation is accelerated, stress activation-deterioration by oxidation habituation, material antifatigue aging improves.
The selected tenderizer of the present invention can increase plasticity, mobility, is convenient to processing; Reduce the viscosity of melting temperature and sizing material, be conducive to Synergist S-421 95 and disperse, reach energy-conservation object; Can also make elongation, the rebound resilience of cross-linked rubber improve, low-temperature performance is good, and heat-dissipating is little; Except above-mentioned effect, the resistance to fatigue of all right Reinforced Rubber.
In the present invention, add suitable tenderizer and softening agent, can improve the antifatigue life-span of rubber, this can not simply from strengthening rubber molecule mobility, this explains on the one hand, but because softening agent is distributed in supramolecular structure interfacial layer, has improved rubber molecule mobility and caused.
The fatigure failure of material occurs under long-time loop cycle, in its fatigue process, inevitably to contact with oxygen, ozone, ultraviolet ray, microorganism and corrosive deposit etc., thereby because of the antifatigue destructive characteristics of aging or infection material, therefore in rubber components, add suitable anti-aging agent can effectively reduce the destruction to sizing material fatigue performance such as oxygen, ozone, light and heat.Different anti-aging agent prevents the chemical degradation reaction of sizing material by different protective mechanisms; Wax can migrate to sizing material surface; between objectionable impurities in rubber and environment, form one deck physical protection film; other anti-aging agent by directly with cause degradation material or with other, necessary material generation of DeR chemical reaction occur, thereby the protective effect of playing.
Beneficial effect of the present invention is, rubber of the present invention and common rubber phase ratio, have good heat-proof aging, anti-dynamic fatigue property, can be used as needing the long-time rubber item in fatigue state.
