Abstract

A kind of method that utilizes vegetable gum to prepare sealing ring, first prepare vegetable rubber powder, the ratio of obtained vegetable rubber powder and natural rubber latex is 1:3, mix uniformly and make glue; Dried plain cotton canvas is dipped in glue for 20 After ~40 minutes, it is extruded by a double-roller calender (roller speed ratio is 1:1, and the roller distance is 3mm), and then dried to obtain the adhesive tape; the adhesive tape is cut according to the specification at an angle of 45° and spread into 2 to 3 layers. Compact it and put it into the sealing ring mold. The inner wall of the mold is coated with wear-resistant glue, and it is vulcanized at 145-155°C and 8-10-MPa for 30-45-minutes. After the formed sealing ring is put into Soak in 35 parts of strengthening agent for 2 hours, remove air bubbles in the system under low pressure, after drying, apply a layer of wax with plain cotton canvas, and then heat-treat at 100°C for 4 hours, and then it can be completely cured. The performance of the sealing ring of this method is stable, it is not easy to swell in the medium, the heat shrinkage effect is small, and the expansion strength, elongation and tear resistance are enhanced at the same time.

Description

Technical field: [0001] The invention relates to a sealing ring, in particular to a method for preparing the sealing ring by using vegetable glue. Background technique: [0002] The sealing ring is an annular cover composed of one or several parts, which is fixed on a ring or washer of the bearing and contacts with another ring or washer or forms a narrow labyrinth gap to prevent the leakage of lubricating oil and the intrusion of foreign objects. The sealing ring is a rubber ring with a circular cross-section. Because of its O-shaped cross-section, it is called an O-ring. [0003] The existing sealing rings include rubber sealing rings and metal sealing rings. Metal sealing rings have strong characteristics and do not contain any rubber components, while rubber sealing rings are mostly composed of rubber chemical components. The preparation process has a great impact on the staff. At the same time polluted environment. Invention content: [0004] The technical problem t...
