Abstract
The invention relates to a preparation method of a blocking edge abrasion preventing conveying belt. The preparation method comprises the following steps of putting raw rubber, an active agent, an anti-aging agent and a filling reinforcing agent into an internal mixer for glue discharging after mixing and cooling after glue discharging so as to obtain a mixed rubber section I; mixing the section of mixed rubber and a vulcanizing agent on an open type rubber mixing mill, performing piece discharging after turning and cooling after piece discharging to obtain a mixed rubber section II; adding the mixed rubber section II into an extruder, and obtaining an upper covering rubber layer after extrusion; taking a tape core layer, a lower covering rubber layer and edge rubber, and performing one-time fitting of the upper covering rubber layer, the tape core layer, the lower covering rubber layer and the edge rubber on a forming machine to obtain a blank; and stretching the blank, attaching an ultra-high molecular polyethylene film on the upper surface of the upper covering rubber layer of the blank, and finally vulcanizing the blank adhering to the ultra-high molecular polyethylene film toobtain the conveying belt capable of preventing blocking edge abrasion. The ultra-high molecular polyethylene film is attached to the conveying belt to cover the two sides and to realize co-cross-linking through high-temperature vulcanization, so that the interface locking force is good.
Description
technical field [0001] The invention relates to a method for preparing a conveyor belt, in particular to a method for preparing a conveyor belt which prevents sidewall wear. Background technique [0002] When using the conveyor belt to transport materials, in order to prevent the material from leaking, set sidewall belts on both sides above the conveyor belt, but most of the sidewall belts are processed from used old belts. As we all know, rubber is a viscoelastic material, and there is a large friction coefficient between the rubbers. Clear wear marks can be seen where the edge belt and the conveyor belt contact. service life. [0003] In order to overcome the wear and tear of the sidewall belt, the research and development focus is on the sidewall belt. For example, Jiangyin Tianxiang Plastic Belt Co., Ltd. has developed a polyurethane combined sidewall conveyor belt; authorized announcement number: CN 207482706 U The development structure is "U" shaped Compression sidew...
