Description
Technical field
The present invention relates to the goods transportation art of metallurgy, chemical industry and building materials, be specifically related to a kind of high-temperature resistant rubber conveying belt and production method thereof.
Background technology
At metallurgy, industries such as building materials need be carried high-temp solid material, as sintered ore, cement clinker, lime and coke etc., standard GB/T20021-2005 is divided into heatproof zone four grades such as T1, T2, T3, T4, its experimental temperature is respectively 100 ℃, 125 ℃, 150 ℃, 175 ℃, allow use temperature below 175 ℃, and the working temperature of these industries can reach 300-500 ℃.Catabiosis such as in use be easy to chap, come unstuck has just been scrapped later on.Existing production method is in order to improve the work-ing life of product, general all be select can be relatively with the rubber of high temperature, as styrene-butadiene rubber(SBR), terpolymer EP rubber etc. and by the research to its prescription, comprise prescription of material of main part and rubber cover etc., but still can't satisfy high request to resistance to elevated temperatures, still need its work-ing life further to improve, to reduce replacement cost.
Summary of the invention
A kind of high-temperature resistant rubber conveying belt and the production method thereof of providing of the present invention.When the heat in the material of conveying belt is transmitted to conveyer belt coating rubber surperficial, heat can be absorbed, thereby stops the rubber temperature in the rubber cover to rise rapidly, also stops heat to the conveying belt conducted inside, postpone the aging of conveying belt, guarantee to prolong the work-ing life of conveying belt.
Dehydration reaction can take place in the multi-crystallization water compound under the condition of high temperature, absorb the heat in the rubber, reduces the temperature of rubber, postpones the aging of rubber, the work-ing life of improving high temperature-resistance conveyor belt.
Be not that all multi-crystallization water compounds all can satisfy the use needs, they must possess following performance:
1 has well actively mutually with rubber, rubber is had strengthening action preferably.
2 are difficult for dehydration in the course of processing of rubber.
Temperature lowers and can absorb water after 3 high temperature dehydrations, and namely process is reversible.
4 thermal conduction capability are low
The crystal water of 5 combinations is many.
6 do not promote the effect of ageing of rubber.
