Problems solved by technology

Some people have studied to improve the compression resistance of asbestos-free cork rubber pads used in ships, but because no breakthrough has been made in the proportion of nitrile rubber, cork powder and various accelerators, the current domestic production of asbestos-free cork The compression resistance of rubber mats is generally low, and it still needs to be imported from abroad

Abstract

The invention discloses a marine rubber, which is composed of the following components in mass percentage: nitrile rubber 26: 22-35, 4# cork powder (40-60 mesh): 14-16, 5# cork powder (60-mesh 100 mesh): 17~25, light calcium carbonate: 16~20, zinc oxide: 1.7~2.5, accelerator sulfur: 0.25~0.37, accelerator TDTM: 0.37~0.5, accelerator DM: 0.37~0.5, antioxidant RM: 0.37~0.5, stone powder: 6.2~9.92, solid Malone: ​​1~1.49, resin 2123: 1.24~1.49. The marine rubber disclosed by the invention greatly improves the compressive performance of the non-asbestos rubber pad, basically meets the requirements for installation of ship equipment, does not pollute the environment, and meets the requirements of the International Maritime Organization for ship transportation.

Description

technical field [0001] The invention relates to polymer materials, in particular to a marine rubber. Background technique [0002] Cork rubber pads are widely used in pipe flange connections on ships. In order to improve the compression resistance of cork rubber pads, an appropriate amount of asbestos is often added to cork rubber pads. In recent years, the International Maritime Organization has stipulated that the use of asbestos-containing products on ships is prohibited. In the face of my country's growing ocean transportation force, whether it is new ships or ship repairs, it is urgent to solve the problem of low compressive performance of asbestos-free cork rubber mats. . Some people have studied to improve the compression resistance of asbestos-free cork rubber pads used in ships, but because no breakthrough has been made in the proportion of nitrile rubber, cork powder and various accelerators, the current domestic production of asbestos-free cork The compression re...
