Abstract

The invention discloses a method for improving wear resistance of a plastic sealing element. The method comprises the operation steps as follows: (1) the formed plastic sealing element is subjected to oil and dirt removal treatment, and the treated plastic sealing element is placed in hot water and subjected to ultrasonic-assisted treatment for 20-25 min; (2) the plastic sealing element treated in the step (1) is soaked in a wear-resistant treatment solution for 2-3 h; (3) a stationary liquid is sprayed on the surface of the plastic sealing element treated in the step (2), ventilation treatment is performed for 1 h, and a finished product is obtained after drying. The operation method for improving wear resistance of the plastic sealing element is simple to operate, low in cost, green, safe and environmentally friendly, few three wastes are produced, original excellent performance of the sealing element cannot be damaged, the wear resistance of the surface of the sealing element can be effectively improved, and the service life of the sealing element is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of seal preparation, and in particular relates to a method for improving the wear resistance of plastic seals. Background technique [0002] Seals are materials or parts that prevent fluid or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from invading the internal parts of the machine. Although the seal is small, its function makes it a basic component and accessory in the main industries of the national economy such as national defense, chemical industry, petroleum, coal, transportation and machinery manufacturing, and occupies a very important position in the development of the national economy. Although the common plastic seals currently available on the market have excellent corrosion resistance, their wear resistance is poor, which seriously affects their service life. Contents of the invention [0003] In order to solve the above ...
