High-elasticity waterproof O-type ring

Abstract

The invention discloses a high-elasticity waterproof O-type ring. The O-type ring is prepared by the following raw materials in parts by weight: 40-60 parts of methyl methacrylate, 10-20 parts of acrylonitrile, 1-10 parts of polypropylene, 15-35 parts of organic silicone resin, 1-10 parts of vulcanized rubber, 5-15 parts of organic fluorine polymer, 1-5 parts of zinc oxide, 0.5-6 parts of an antioxidant, 0.5-2.5 parts of a plasticizer, 1-10 parts of ethyl acrylate, and 10-25 parts of styrene. The product can satisfy the basic usage requirement of the O-type ring, can greatly increase the product elasticity, and has the advantages of good waterproof performance, antioxidation and corrosion resisting performance.

Description

technical field [0001] The invention relates to a health-care sand, in particular to a high-elasticity waterproof O-ring. Background technique [0002] O-ring O-ring (O-rings) is a kind of rubber sealing ring with a circular cross-section. Because of its O-shaped cross-section, it is called an O-ring rubber sealing ring, also called an O-ring. It began to appear in the mid-19th century, when it was used as a sealing element for steam engine cylinders. O-rings are the most common mechanical design for seals because of their low cost, simplicity of manufacture, reliable function, and simple installation requirements. O-rings are subjected to pressures of tens of Pascals (thousands of pounds). O-rings can be used in static applications as well as in dynamic applications where there is relative movement between components, such as shafts of rotary pumps and pistons of hydraulic cylinders. [0003] At present, the O-rings in the market basically meet the conditions of use, but...
