Abstract
The invention relates to rubber material of a tire, in particular to tire body rubber material utilizing regenerated rubber as well as a blending method and an application thereof in preparing the tire. The tire body rubber material utilizing the regenerated rubber comprises the following components in part by weight: 80-90 parts of pure rubber, 10-20 parts of the regenerated rubber, 50-57 parts of carbon black, 3.50-8.50 parts of adhesion promoter, 5.00-12.00 parts of activator, 2.00-5.00 parts of age inhibitor, 2.00-5.00 parts of vulcanizing agents and 0.8-1.5 parts of vulcanization promoter, wherein the total parts of the pure rubber and the regenerated rubber are 100 parts. The invention replaces the pure rubber with the regenerated rubber, establishes the third rubber resource position of the regenerated rubber following after the pure rubber and synthetic rubber, changes the regenerated rubber from only being used in a mixing way in the rubber product industry and greatly reduces the cost under the condition of ensuring tire quality; in addition, the tire body rubber material can basically meet the requirement of the tire body rubber material on all properties.
Description
Technical field
The present invention relates to the sizing material of tire, relate in particular to a kind of compounding process and the application of this sizing material on the preparation tire of sizing material and this sizing material of the carcass that utilizes reclaimed rubber.
Background technology
Constantly soaring along with crude oil price in recent years, a lot of natural collagen places of production are cut down rubber tree and change and plant palm tree, and oil price is quick-fried rises with reply to utilize palm-kernel to produce biochemical diesel oil, makes originally very nervous natural rubber resource deficient more.Along with the continuous rise in price of natural gum, add that oil price soars, also when the river rises the boat goes up to have caused the synthetical glue valency.Present synthetical glue price one rises and rises again, and SBR is near the natural gum price, and the BR price will be higher than the natural gum price for some time, and the price increase space of tire is very limited.Caused so a lot of tire enterprise particularly oblique tire enterprise be difficult to keep, even the good all-steel radial tyre of gaining is in recent years also had difficulty in taking a step.How to break this deadlock, face natural gum directly, synthetical glue significantly appreciates, probe into the 3rd rubber sources to having carved the stage that to delay.
Reclaimed rubber to the primary product of damaged tire and scrap rubber comprehensive utilization it.In the reclaimed rubber industry, proposed at present to restore the notion of glue, and had manufacturer production to go out the high-quality reclaimed rubber of high-tenacity.The application of reclaimed rubber not only reduces the cost of rubber item, increases economic efficiency, and for saving rubber sources and environment protection very big effect is arranged simultaneously, is the embodiment of recycling economy in rubber industry.Damaged tire except that the reclaimed rubber of producing each class and oil refining, the micelle of also production various uses and rubber powder.Micelle is mainly used in the road surface of physical culture runway and park leisure center, also is used for motorway abroad.
Reclaimed rubber discloses the application of reclaimed rubber to agricultural tyre tread rubber Effect on Performance (" tire industry " 2008 the 28th volume), and its production formula is: NR 40, and SBR 30, BR 30, reclaimed rubber 16, carbon black 61, zinc oxide 4, stearic acid 3, antioxidant 4010NA 1, antioxidant D KF-50 2, protection wax 1.5, aromatic hydrocarbon oil 10, Sulfur/accelerant N OBS 2.4, other are 3.5 years old.Big compatibility test sizing material is mixing in Banbury mixer, and calendering process is: cross roller in NR broken-(down)rubber, BR, SBR, reclaimed rubber and small powder → carbon black → aromatic hydrocarbon oil → binder removal → mill more than 3 times, and the cool glue of rule, temperature is reduced to below 100 ℃.Sulphurization and promotor in the mill of XK2560 type, it is even to smash glue, and following sheet warehouse-in is stand-by.For the sizing material that utilizes reclaimed rubber as carcass open the report do not arranged also.
