Background technology
In port traffic, steel cable core conveying belt is the more commonly used product in transportation.Current harbour steel wire
Wire rope core conveyer belt meets GB/T9770-2013《Ordinary steel rope core conveyer belt》The abrasion loss of abrasiveness material high is conveyed in regulation
It is required that being≤100mm3；Because belt conveyor automaticity is constantly lifted, harbour conveyer belt to large conveying quantity, it is long away from
From, at high speed and strong wear working condition condition development；Unit feedback is used by collecting to collect, steel cable core conveying belt rubber cover mill
Damage is the main cause for causing adhesive tape to damage, and greatly reduces the service life of rope belt；Therefore harbour Steel cord is developed
Conveyer belt coating rubber, particularly high intensity abrasion rubber cover high arise at the historic moment.
There is certain gap in current China and external conveyer belt particularly German conveyer belt industry of going together, Germany
DIN22131-1988 general applications steel cable core conveying belt high wearables abrasion loss≤90mm3, domestic existing same type conveying
Band abrasion are generally more than 90mm3, the purpose of the present invention is started with from meeting DIN22131 standards, and development meets DIN 22131-
1988 steel cable core conveying belt standards so that steel cable core conveying belt rubber cover performance more optimizes.
The content of the invention
It is an object of the invention to provide a kind of harbour high abrasion steel cable core conveying belt rubber cover formula development, and carry
High-wear resistance, increases the service life.
To reach above-mentioned purpose, the present invention is adopted the following technical scheme that：

A kind of harbour steel cable core conveying belt rubber cover preparation method of the invention is comprised the following steps：By Rare-earth Cis fourth
Rubber, solution polymerized butylbenzene diene, age resistor, nano zine oxide, stearic acid, dispersant PL60 and accelerator are added to banbury, banburying 1
~3 minutes, then adding carbon black, softening agent and anti-scorching agent CTP to continue banburying 3~4 minutes, vulcanizing agent banburying 1 is finally being added again
~2 minutes；Dump temperature control exists, the glue of discharge is a kind of port by 6~8mm films that mill goes out
Mouth uses steel cable core conveying belt rubber cover.
A kind of harbour steel cable core conveying belt rubber cover and preparation method thereof of the invention, has second from solution polymerized butylbenzene diene
Alkenyl Mass Distribution is narrow, the few structure of degree of branching, with wear-resisting, cold-resistant, resistance to flexion, the spy that heat is low and curingprocess rate is fast
Point；Rare earth polybutadiene rubber has chain structure regular, good linearity, mean molecule quantity structure high, with intensity is high, resistance to flexion, low
The low feature of heat, rolling resistance；Improve steel cable core conveying belt rubber cover performance from both the above material and with natural gum,
The phenomenons such as rubber cover aging cracking are reduced, anti-wear performance is improved, to extend conveyer belt service life high；Rubber cover tensile strength
Greatly, elongation is high, and rubber cover is applied to the conveying of harbour different material；Its anti-wear performance is excellent, reduces rope belt rubber cover
Abrasion, extends product service life；The present invention is coordinated using solution polymerized butylbenzene diene and rare earth cis-butadiene cement, it is not necessary to which drying glue is plasticated
Operation, reduces energy consumption.
