Technical Field

The invention relates to the technical field of rubber plates, in particular to a rubber plate with good corrosion resistance.

Background

The rubber plate is a sheet product with a certain thickness and a large area, which is called a rubber plate for short, and is prepared by vulcanizing rubber serving as a main material (which can contain reinforcing materials such as fabric, metal sheets and the like). The rubber plate has higher hardness and general physical and mechanical properties, and can work in the air with low pressure and the temperature of 20 to +140 ℃. The rubber sheet is produced by calendering, laminating or extruding the rubber compound, and vulcanizing the rubber compound with a press vulcanizer or continuously vulcanizing the rubber compound with a drum vulcanizer. The rubber gasket is widely used in industrial and mining enterprises, transportation departments, house floors and the like, and is used as a sealing rubber ring, a rubber gasket, a door and window seal, a laying workbench and a floor.

The traditional rubber plate has poor corrosion resistance, the service life of most rubber plates is about 1-3 years, and if the environment is severe, the rubber plates are not required to be replaced within one year, so that the use cost is greatly increased, and therefore, an improved technology is urgently needed to solve the problem in the prior art.
