Description
Technical field
It resists cold fire-retardant rubber cover, the fire-retardant intermediate rubber that resists cold, resistance to the present invention relates to conveyer belt technical field more particularly to one kind
Fire-retardant core rubber of trembling with fear and cold-resistant flame-retardant rope core conveyer belt.
Background technique
Steel core conveyor belt is the main conveyance of underground coal mine, executes MT668-2008 " colliery wire
Wire rope core fire retarding conveying band " standard, there is anti-flammability, antistatic property, but can not resist cold.Currently, China's construction large size, super-huge mine
Mountain, modernizes mine harbour, open coal mine, and iron ore transportation system is almost all made of high strength wire rope core conveyer belt as solid
The mode of movement of body material.Steel cable core conveying belt in the prior art allow using ambient temperature range be -10~40 DEG C,
When temperature makes that rubber cover can be made to be hardened, skid lower than -10 DEG C, reduce the elasticity and groove forming character of conveyer belt, influence conveying effect and
Service life.When environment temperature is lower than -30 DEG C, rubber cover can be made sharply to become fragile, be cracked, the cohesive force of wirerope and rubber it is big
Amplitude reduction seriously affects conveying effect and service life.However, in China northeast and the Northwest or even Russia sieve of severe cold
This area, one to winter, temperature is often at -40 DEG C hereinafter, even lower than -60 DEG C.Therefore, the Northeast, China and Russia etc.
Some mine class engineerings in area there is an urgent need to have it is high-intensitive, suitable for long range, big freight volume, cold-resistant conveyer belt.Cause
This, develops cold-resistant flame-proof armored rope core conveyer belt to solve the regional winter material such as the Northeast, China, the Northwest, Russia
