Problems solved by technology

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and then return to their original shape after the external force is removed. Among them, rubber spring is a non-metallic spring, because it is easy to process , easy to use and widely favored by consumers, but the traditional rubber spring still has the following defects in the process of use: insufficient corrosion resistance, easy aging, affecting the normal use of the spring

Abstract

The invention discloses a corrosion-resistant rubber spring. The corrosion-resistant rubber spring contains a body and a corrosion-resistant layer which is adhered to the surface of the body through high-temperature adhesion; the body is prepared from fluorine rubber and nitrile-butadiene rubber through mixing, wherein the content of the fluorine rubber in the body is 35% to 45% (mass percent), and the content of the nitrile-butadiene rubber in the body is 55% to 65% (mass percent); the corrosion-resistant layer is prepared from epoxy resin and polyester resin through fusing, wherein the content of the epoxy resin in the corrosion-resistant layer is 73% to 77% (mass percent), and the content of the polyester resin in the corrosion-resistant layer is 23% to 27% (mass percent). By the manner, the corrosion-resistant rubber spring can have the characteristics of high corrosion resistance, high aging resistance and good heat resistance, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to the field of springs, in particular to a corrosion-resistant rubber spring. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and then return to their original shape after the external force is removed. Among them, rubber spring is a non-metallic spring, because it is easy to process , easy to use and widely favored by consumers, but the traditional rubber spring still has the following defects in the process of use: insufficient corrosion resistance, easy aging, which affects the normal use of the spring. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a corrosion-resistant rubber spring, which can have the characteristics of high corrosion resistance, strong aging resistance and good heat resistance, and greatly increase the service life.
