Description

A kind of agricultural tyre sidewall rubber of high filling tyre reclaim
Technical field
The present invention relates to a kind of agricultural tyre sidewall rubber 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 more.Report The processing of damaged tire has become generally acknowledged international headache, no exception in China.And reclaimed rubber is used as the good of twice laid Good mode, it is one of effective way that the tire recycling for solving China, which is utilized,.Handled by process, tire reclaimed rubber is produced Come, be put among new product production so that rubber sources is adequately and reasonably recycled, and is all to resource, environment Good processing mode.
Phenyl is introduced in the side base of styrene butadiene rubber sbr molecular backbone, and in butadiene 1,2- structures form ethene side base, Steric hindrance is big, and Chain Flexibility is poor, average molecular chain narrowly distributing, lacks the plasticization of low molecule rank, therefore processability Can be poor.When being in particular in mixing, the wetting power to compounding ingredient is poor, and quick heating, machine utilization is big；During calendering, sizing material shrinks Property is big；Operating difficulties during extrusion, semi-finished product expansion rate is big；Tack is poor during shaping.Agricultural tyre tyre surface large usage quantity, if sizing material Quick heating, mixing time is long, and not only sizing material is easy to incipient scorch, and the problems such as plant capacity is big.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the invention provides a kind of agricultural tyre of high filling tyre reclaim Sidewall rubber, it includes following raw material and its mass fraction：
20# standard rubbers, 15-25 parts；Cis-butadiene cement 9000,15-25 parts；Butadiene-styrene rubber 1502,10-30 parts；Tyre reclaim, 50-30 parts；Zinc oxide, 3.0-5.0 parts；Stearic acid, 2.0-4.0 parts；Antioxidant 4020,1.5-2.5 parts；Anti-aging agent RD, 0.8- 1.2 part；Protection wax, 2.0-3.0 parts；High abrasion furnace carbon black N330,20-30 parts；Universal carbon black, 30-40 parts；Aromatic naphtha, 3.5-4.5 Part；Pine tar, 2.5-3.5 parts；Coumarone, 2.5-3.5 parts；Sulfur, 1.4-1.8 parts；Accelerant NOBS, 0.6-1.0；Uniform point Powder 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 rubbers and the mass fraction sum of cis-butadiene cement 9000 are 40 parts.
Described tyre reclaim is：ML100 DEG C of Mooney viscosity（1+4）85, tensile strength9MPa, elongation at break360 %。
Present invention has the advantages that：
（1）, the poly- SBR of low temperature breast be unsaturated rubber, number of double bonds is few, and methyl side groups are not present and its electronics work is pushed away Active relatively low with, double bond, curingprocess rate is slow, adds tyre reclaim（TRR）It is blended, the vulcanization speed of sizing material can be accelerated Degree, and recovery tendency is small；In addition, tyre reclaim（TRR）Addition, can make mixed refining process process heat reduce, it is to avoid Sizing material incipient scorch, can also make mix quality uniform, and can save man-hour, reduce power consumption；Also can reduce calendering when receipts Dilatancy when contracting and extrusion, semi-finished product less appearance defects；Increase the tack of sizing material simultaneously, improve sizing material and sizing material Between, the adhesive force between sizing material and cord, so as to improve the poly- SBR of low temperature breast processing characteristics.
（2）, using SBR/TRR mixed systems, not only can improve tyre performance but also accomplish that resource is followed to a greater extent Ring is utilized, and is reduced pollution, is protected environment.
（3）, cost analysis：SBR1502 prices are higher in the market, about 10-18 members/Kg, and tyre reclaim TRR Price is relatively low, and about 2.0-6.0 members/Kg, SBR price is about 3-9 times of TRR prices, uses tyre reclaim, it is possible to decrease system Product cost about 10-30%.
