Problems solved by technology

However, due to the difficulty of foaming and vulcanization technology of foamed silicone rubber, and the consequence of its poor adhesive performance due to its excellent chemical stability, there are only a large number of standard silicone rubber materials extruded on the market. The strip-shaped foamed silicone rubber produced by the equipment and vulcanization equipment is used as the sealing material, and it is difficult to see the circular sealing ring
A complete circular sealing ring is usually only manufactured by a special foaming mold, which is technically difficult and expensive, which seriously limits the popularization and application of foamed silicone rubber rings

Embodiment Construction

[0019] Referring to Figures 1 and 2, use long strips of elastic foamed silicone rubber (also known as silicone rubber sponge) sold on the market, and cut obliquely according to the circumference of the required sealing port diameter, and keep the foamed silicone rubber strip 1 by the cutting process. The obtained two planar end surfaces 2 form an angle of 45° with the longitudinal direction α of the foamed silicone rubber strip 1 . Clean end face 2 with alcohol and allow to dry. Then apply a layer of Loctite 596 adhesive evenly on the two end faces 2, then surround the foam silicone rubber strip 1 into a circle and make the two end faces 2 butt together, and then use a simple clamp to keep them close to each other In the pasted state, let it stand at room temperature for 24-48 hours in this close-fit state, and a firm and elastic foamed silicone rubber ring 3 will be formed. The bonded tensile strength of the obtained foamed silicone rubber ring 3 at the position of the joint...

Abstract

The invention relates to a production method of foaming silicon rubber rings. The steps in sequence adopted are: (1) cutting long foaming silicon rubber into prearranged length; (2) coating Loctit 596 adhesive on end face of a foaming silicon rubber strip cut in the step (1); (3) leading the end faces of the foaming silicon rubber strip obtained in the step (2) to be aligned and attached, standing silently. The production method of the rubber rings applies simple production equipment and short production process period, and the foaming silicon rubber rings obtained have good adhesive intensity and notable environmental and economic benefits.

Description

technical field [0001] The invention relates to a method for making a foamed silicon rubber ring, in particular to a method for making a ring-shaped rubber ring by using a strip-shaped foamed silicon rubber rod as a raw material. Background technique [0002] The integrated process box or split process box is a container for storage and supply of developer such as toner for laser copiers, laser printers and other office equipment. Usually after the toner contained in the process cartridge is depleted, it needs to be refilled with toner before it can be used for subsequent copy or print jobs. The filled toner is generally stored in bottled toner containers corresponding to capacity specifications according to different storage requirements. On the other hand, most of the toners put on the market by suppliers are packaged in drums or bags with a capacity of tens to hundreds of kilograms, for example, 40, 80 or 400 kilograms. Secondary packaging of this large barrel of toner ...
