The oil-resistant rubber sheet is a sheet-like rubber product having a certain thickness and a large area which is obtained by vulcanizing oil-resistant rubber as a main material, and the nitrile rubber and the nitrile reclaimed rubber are main raw materials for producing oil-resistant rubber sheets. The nitrile oil resistant rubber sheet can be used as a rubber mat, a sealing strip, a floor, a laying workbench, etc. in the case of contact with oil media such as industrial, mining, transportation, and house floors. The high proportion of recycled rubber in the oil resistant rubber sheet can significantly reduce the cost of raw materials.
Nitrile rubber, 20 parts; nitrile reclaimed rubber, 100 parts; fine odorless reclaimed rubber, 200 parts; zinc oxide, 6 parts; sulfur, 3.5 parts; accelerator M, 0.5 parts; accelerator DM, 1.5 parts; CZ, 1.5 parts; accelerator TMTD, 0.2 parts; stearic acid, 2 parts; paraffin, 2 parts; antioxidant SP-C, 2 parts; semi-reinforcing carbon black, 40 parts; sericite powder, 80 parts; : 459.2 parts.
The nitrile reclaimed rubber is mainly processed from the products of nitrile rubber, nitrile water, and waste nitrile gloves. It retains most of the molecular structure and performance characteristics of nitrile rubber, and has excellent oil resistance and replaces nitrile. Rubber production of oil-resistant rubber sheet can not only ensure the excellent oil resistance of rubber sheet, but also significantly reduce the cost of raw materials; a small amount of nitrile rubber can further improve the oil resistance of oil-resistant rubber sheet and will not bring too much burden to the cost. Small investment, big gain"; fine and odorless tire reclaimed rubber has low price, good fineness and no irritating odor. Adding a large amount to the nitrile oil resistant rubber sheet can reduce the production cost and improve the wear resistance of the rubber compound; To meet the comprehensive requirements of oil-resistant rubber sheet for oil resistance and heat resistance, soft carbon black is generally used in the formulation; sericite powder can effectively shield ultraviolet, microwave, infrared, improve the aging resistance of oil-resistant rubber sheet, soft carbon The combination of black and semi-reinforcing carbon black can maintain the properties of the rubber compound while reducing the cost of the oil resistant rubber sheet.
Mixing process: nitrile reclaimed rubber, fine and odorless reclaimed rubber as the main raw material of the nitrile oil resistant rubber sheet. When mixing, first need to masticize 20 parts of nitrile rubber. After the mastication is completed, the rubber is refined. After the 3-5 times of thinning on the machine, the nitrile reclaimed rubber and the fine and odorless reclaimed rubber are added 3-5 times, and then the nitrile rubber, the nitrile reclaimed rubber and the fine and odorless reclaimed rubber are uniformly mixed according to the ordinary mixing process. Mixing.
The oil-resistant rubber sheet produced by using nitrile rubber, nitrile reclaimed rubber and fine odorless reclaimed rubber has excellent oil resistance and low production cost, and can be drawn in the fierce market competition; in order to satisfy more users of oil-resistant rubber sheets The specific requirements of various performances, manufacturers can also adjust the application ratio of nitrile rubber, nitrile and fine odorless reclaimed rubber according to the actual situation, to meet the needs of customers as the primary goal, purposefully reduce the low cost in the premise of ensuring quality.
