Problems solved by technology
[0003] The rubber coating layer of the existing ordinary rollers cannot work in chemicals such as acid, alkali, and salt solution. When the rubber coating layer of ordinary rollers is in contact with acid, alkali, and salt solution, it will cause corrosion, cause rubber swelling, and produce rubber molecules. Fracture, depolymerization, and decomposition and dissolution of compounding agents lead to a significant decrease in its mechanical strength and physical properties, and the rubber layer gradually becomes sticky, oxidized, hardened, embrittled, cracked, etc., and cracks occur due to the attack of ozone. So that the corrosion completely loses the ability to work

Embodiment 1
[0015] Get the following raw materials in parts by weight, natural rubber 100, sulfur 3, N-cyclohexyl-2-benzothiazole sulfenamide 1, zinc oxide and stearic acid 10, high wear-resistant carbon black 50, vaseline 15, N- Phenyl-a-naphthylamine 4, barium sulfate 20.
[0016] According to the following steps: first step, rubber preparation: prepare materials according to the above components and parts by weight; then carry out natural rubber mastication; then put the above raw materials into the internal mixer for mixing in turn, mix evenly Glue, glue removal temperature 120°C; press on the open mill, park to cool, then add vulcanizing agent on the open mill and release the tablet, park and cool for more than 8 hours for use;
[0017] The second step, molding: heat the rubber compound prepared in the first step above which is cooled and ready to be used on an open mill, and refine it to produce a sheet;
[0018] The third step, vulcanization: adopt the direct steam internal contro...

The invention discloses a rubber coated layer, the rubber coated layer comprises the following components by weight: 100 parts of natural rubber, 3-5 parts of sulfur, 0.6-1.5 parts of N-cyclohexyl-2-benzothiazole sulfonamide, 7-12 parts of zinc oxide and stearic acid, 40-70 parts of high wear-resistant carbon black, 7-20 parts of vaseline, 3-5 parts of N-phenyl-a-naphthylamine and 15-30 parts of barium sulfate. Compared with the prior art, the rubber coated layer is prepared from new formula material, and can keep original physical and mechanical properties for a long time under the action of acid and alkali bath, so that a conveyor roller can be used in acid and alkali and chemical medicine environment for a long time.
Description
[0001] technical field [0002] The invention relates to the technical field of conveyors, in particular to a rubber covering layer and a preparation method thereof. Background technique [0003] The rubber coating layer of the existing ordinary rollers cannot work in chemicals such as acid, alkali, and salt solution. When the rubber coating layer of ordinary rollers is in contact with acid, alkali, and salt solution, it will cause corrosion, cause rubber swelling, and produce rubber molecules. Fracture, depolymerization, and decomposition and dissolution of compounding agents lead to a significant decrease in its mechanical strength and physical properties, and the rubber layer gradually becomes sticky, oxidized, hardened, embrittled, cracked, etc., and cracks occur due to the attack of ozone. So that the corrosion completely loses the ability to work. [0004] With the continuous development of industrial production, the use of rollers is required to be more and more wide...
