Abstract

The invention discloses a formula of a rubber piston. According to parts by weight, the formula comprises 288-352 parts of nitrile butadiene rubber, 14.4-17.6 parts of a reinforcing agent, 3.6-4.4 parts of a stearic acid, 117-143 parts of phenolic resin, 117-143 parts of white carbon black, 6.3-7.7 parts of an adhesive agent, 5.58-6.82 parts of a promoting agent, 28.8-35.2 parts of dibutyl ester, 10.8-13.2 parts of sulfur and 0-0.3 part of epoxy resin. The rubber piston has good sealing performance; and the sealing performance and deformation thereof achieve the operating requirements.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber formula and a preparation method for making pistons. Background technique [0002] With the advancement of science and technology, the current piston is generally used to isolate the material in the container from the outside world, and can be used to prevent oil, water, corrosion, seal gas or prevent leakage. It has a wide range of uses, but due to the limitations of the manufacturing process and formula of the piston, the sealing and deformation of the piston cannot reach a relatively best value, so the pistons currently on the market are generally poor in sealing and unreliable in quality, which is easy to cause losses. Contents of the invention [0003] The invention provides a formula and a preparation method of a rubber piston with good sealing performance, whose sealing performance and deformation meet the use requirements. [0004] In order to solve the above p...
