Description
Technical Field
The invention relates to a rubber conveying belt, in particular to a special conveying belt for a special large-scale mine.
Background
With the improvement of automation and mechanization degree, the development of large-scale mines at home and abroad is increased year by year. Therefore, higher and harsher requirements are provided for various related supporting facilities, the conveying belt transportation is the most economic transportation mode for transporting mine materials which are inconvenient, rugged and steep on roads, but the working conditions are extremely severe and mainly appear in the following aspects: large material diameter (mostly 200-600 mm), sharp and irregular material fall (mostly falling to more than 2 meters), heavy material ratio and the like. Therefore, the conveyor belt is also required to have impact resistance, cutting resistance, and no delamination.
At present, the problem of short service life of conveying belt products at home and abroad generally exists under the working condition, and various damages occur after the conveying belt products are used for 1-2 months, so that the conveying belt products cannot be continuously used and the working efficiency and the benefits are seriously influenced. Among the most common forms of damage are: (1) impact damage and delamination of the framework material; (2) the working face covering layer is impacted and cut to fall off the blocks; (3) the working surface covering is worn away from the powder. Therefore, it is necessary to develop a long-life rubber conveyor belt for large mine working conditions.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide the special conveying belt for the special large-scale mine, the conveying belt has the advantages of impact resistance, cutting resistance, wear resistance and the like, the framework is not easy to damage and delaminate, the conveying belt is used for large-scale mine development, and the conveying belt has the advantage of long service life, so that the working benefit and the economic benefit are improved.
The technical scheme adopted by the invention is as follows:
the special large-scale mine conveying belt comprises a working surface covering rubber layer, a framework layer and a non-working surface covering rubber layer; the framework layer comprises a spiral steel mesh belt core and core glue which is compounded with the spiral steel mesh belt core into a whole; the formula proportion of the working face covering glue layer is as follows in parts by weight: comprises 60 to 80 portions of neoprene, 40 to 50 portions of natural rubber, 2 to 7 portions of sulfur, 1 to 5 portions of assistant cross-linking agent TAIC, 20 to 30 portions of zinc oxide, 1 to 5 portions of stearic acid, 1 to 2 portions of calcium stearate, 40 to 57 portions of modified composite filler and 1 to 5 portions of anti-aging agent.
Further, the formula proportion of the modified composite filler is as follows in parts by weight: 3 to 4 parts of 2-bromine-2-methylpropionyl bromide, 2 to 3 parts of 4-dimethylaminopyridine, 20 to 25 parts of lignin, 20 to 30 parts of acrylic acid monomer, 60 to 70 parts of acrylonitrile monomer, 130 to 150 parts of ethyl orthosilicate, 1 to 2 parts of 2,2' -bipyridine, 0.3 to 1 part of reactant, 2 to 3 parts of coconut diethanolamide and 2 to 3 parts of sodium carboxymethylcellulose.
