According to antifatigue physical disturbance, can utilize tenderizer or softening agent to control fatigue of materials weathering process, power-chemical theory from 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.
