Description
Technical field
The present invention relates to the agricultural tyre sidewall rubber of a kind of high filling tyre reclaim, belong to tire manufacturing art。
Background technology
China is not only rubber import big country, or scrap rubber produces big country, and the total amount of annual Scrap tire is very many。The process of Scrap tire has become as generally acknowledged international headache, no exception in China。And reclaimed rubber is as the good way of twice laid, it is one of effective way that the tire recycling solving China is utilized。Processing through operation, tire reclaimed rubber is produced, and is put in the middle of new product production so that rubber sources is adequately and reasonably recycled, and is all good processing mode to resource, environment。
Introducing phenyl on the side base of styrene butadiene rubber sbr molecular backbone, and form ethylene side base in butadiene 1,2-structure, sterically hindered Chain Flexibility is poor greatly, average molecular chain narrowly distributing, lacks the plasticization of low molecule rank, therefore poor processability。When being in particular in mixing, the wetting power of compounding ingredient is poor, quick heating, machine utilization is big；During calendering, sizing material contractility is big；Operating difficulties during extrusion, semi-finished product expansion rate is big；During molding, autohension is poor。Agricultural tyre tyre surface large usage quantity, if sizing material quick heating, mixing time is long, and not only sizing material is prone to incipient scorch, and the problems such as plant capacity is big。
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides the agricultural tyre sidewall rubber of a kind of high filling tyre reclaim, it includes following raw material and mass fraction thereof:
20# standard rubber, 15-25 part；Cis-butadiene cement 9000,15-25 part；Butadiene-styrene rubber 1502,10-30 part；Tyre reclaim, 50-30 part；Zinc oxide, 3.0-5.0 part；Stearic acid, 2.0-4.0 part；Antioxidant 4020,1.5-2.5 part；Anti-aging agent RD, 0.8-1.2 part；Protection wax, 2.0-3.0 part；High abrasion furnace carbon black N330,20-30 part；Universal carbon black, 30-40 part；Aromatic naphtha, 3.5-4.5 part；Pine tar, 2.5-3.5 part；Coumarone, 2.5-3.5 part；Sulfur, 1.4-1.8 part；Accelerant NOBS, 0.6-1.0；Dispersed dose of MS, 0.6-1.0 part。
Described butadiene-styrene rubber 1502 and the mass fraction sum of tyre reclaim are 60 parts。
Described 20# standard rubber and the mass fraction sum of cis-butadiene cement 9000 are 40 parts。
Described tyre reclaim is: Mooney viscosity ML100 DEG C (1+4)85, hot strength9MPa, elongation at break360%。
The medicine have the advantages that
(1), the poly-SBR of low temperature breast be unsaturated rubber, double bond number is few, and is absent from methyl side groups and pushes away electronic action, the activity of double bond is relatively low, and curingprocess rate is slow, adds tyre reclaim (TRR) and carries out blended, the curingprocess rate of sizing material can be accelerated, and recovery tendency is little；It addition, the addition of tyre reclaim (TRR), the raw heat of mixed refining process process can be made to reduce, it is to avoid sizing material incipient scorch, mix quality also can be made uniform, and man-hour can be saved, reduce power consumption；Also can reduce calendering time contractility and extrude time dilatancy, semi-finished product less appearance defects；Increasing the autohension of sizing material simultaneously, improve between sizing material and sizing material, the adhesive force between sizing material and cord, thus improving the processing characteristics of the poly-SBR of low temperature breast。
(2), use SBR/TRR mixed system, not only can improve tyre performance but also accomplish resource circulation utilization to a greater extent, reduce pollution, protect environment。
(3), cost analysis: SBR1502 price is higher in the market, is about 10-18 unit/Kg, and tyre reclaim TRR price is relatively low, it is about 2.0-6.0 unit/Kg, the price of SBR is about 3-9 times of TRR price, uses tyre reclaim, it is possible to decrease goods cost is about 10-30%。
