Problems solved by technology

[0002] Materials will be transported in the form of lumps, granules and powders of different shapes and sizes through the conveyor belt. The rubber conveyor belt used for outdoor operation, if it encounters wet or low temperature, rain and snow, the material with strong water absorption is easy Moisture, and the wet material is easy to adhere to the surface of the conveyor belt during transportation, severely wears the belt body, shortens the service life of the conveyor belt, and enters the return section with the conveyor belt, causing material accumulation on the transportation line, and material adhesion is equivalent to adding Enlarging the local diameter of the roller will cause the conveyor belt to deviate on the driving roller or the tail roller, and the adhered material will make the conveyor belt slip, reduce the conveying efficiency, and may also cause problems such as structural deformation and breakage of the conveyor belt
Once these problems occur, it is difficult to deal with them quickly on site, causing great losses to production
The materials adhered to the surface of the conveyor belt cannot be cleaned by the cleaner in time, and they are scattered around the conveyor, which seriously affects the on-site environment, and wastes materials, increasing the workload of cleaning the on-site environment
If a cleaner is installed, it is easy to scratch the belt body by the cleaner scraper, which also shortens the service life of the cleaner; if manual cleaning is arranged, the cost is high, and the flying materials may be harmful to the human body
Adhesive material on the surface of the conveyor belt not only reduces the conveying efficiency, the conveyor belt slips and consumes electric energy, but also the material is acid-base or corrosive, which will corrode the conveyor belt all the time and reduce the service life of the conveyor belt. The material adheres to the conveyor belt and causes extreme pollution. It is easy to cause the conveyor belt to be scratched or even broken, and there is also the possibility of work-related accidents

Abstract

The invention discloses an anti-adhesion conveying belt and a preparation process thereof. Comprising upper covering glue, upper sticking glue, a belt core, lower sticking glue and lower covering glue. The 5-chloroisophthalic acid modified chlorinated paraffin and the superfine active pottery clay are added into the adhesive tape, so that the adhesive strength of the conveying belt under repeated flexing in the using process is guaranteed. Oleamide and a perfluorinated copolymer are added into the covering rubber to play lubricating and anti-adhesion roles, and meanwhile, an anti-adhesion film of which the surface is of a micro-nano double-layer coarse structure is coated on the surface of the covering rubber, and a micro-nano second-order composite surface structure formed by the anti-adhesion film is adopted, so that the form and stability of water drops on the surface of the covering rubber are kept. The original hydrophobic structure can be kept for a long time without being damaged, the hydrophobic stability is relatively good, the anti-adhesion effect is good, and industrial transportation and use are facilitated.
