Elastomer for high and low temperature test chamber and manufacturing method of elastomer

Abstract

The invention relates to an elastomer for a high and low temperature test chamber and a manufacturing method of the elastomer, wherein the elastomer is formed by compounding a foaming inner core and a silica gel outer layer wrapping the foaming inner core, and the silica gel outer layer is tightly connected with the foaming inner core in a vulcanization coating mode. The manufacturing method comprises the steps of foaming molding, coating molding and finishing, and comprises the steps: firstly, obtaining a foaming body through a foaming process, making the foaming body into a required foaming inner core, then putting the obtained foaming inner core into a mold, and coating the periphery of the foaming inner core with a silica gel outer layer through a vulcanization coating process to form a composite elastomer; and finally, carrying out demolding and burr treatment operation on the obtained elastomer, and thus obtaining the elastomer suitable for the high and low temperature test box. The elastomer has excellent elasticity and space structure, is resistant to high and low temperature, and is suitable for manufacturing a hole plug of the high and low temperature test box so as to improve the workability of the test box. The manufacturing steps are simple, the product composite structure is compact and not easy to separate, the manufacturing cost is low, and industrial popularization and utilization are met.

AI Technical Summary

Problems solved by technology

The hole plug is a part used to cover the test hole on the high and low temperature test chamber. Most of the existing hole plugs are rubber entities of a single material, which are bulky in shape, insufficient in elasticity, and have a short service life. There is a problem of poor sealing of the test hole, which affects the work of the test chamber
