Sealing strip butt joint sheet rubber material and preparation method, and processing method and processing device for seal strip butt joint thin film

Abstract

The invention provides a sealing strip butt-joint thin slice rubber material and a preparation method thereof, and a sealing strip butt-joint thin slice rubber sheet processing method and processing device. According to the sealing strip butt-joint thin slice rubber material and the preparation method thereof, various raw material components are screened and compounded, a rubber one-section mixing process is adopted, and the sealing strip butt-joint thin slice rubber material for preparing a sealing strip butt-joint thin slice rubber sheet having excellent properties by an extruding process can be obtained. Compared with a conventional sealing strip butt-joint thin slice rubber sheet processing method, the sealing strip butt-joint thin slice rubber sheet processing method can significantly improve the processing efficiency and the product quality, solves the storage problems of a product in a conventional process, and is beneficial to wide application.

Description

technical field [0001] The invention relates to the technical field of butt jointing of sealing strips, in particular to a rubber material for butt jointing of sealing strips and a preparation method thereof. The invention also relates to a processing method and a processing device for preparing a sealing strip butt joint thin film film from the sealing strip butt joint thin film rubber material. Background technique [0002] The main function of the sealing strip is to play the role of sealing, dustproof, waterproof, shock absorption and decoration. According to different assembly parts, the automobile sealing strip is mainly divided into door sealing strip, door frame sealing strip, glass groove sealing strip, trunk sealing strip Sealing strips and cabin sealing strips, etc., and the production processes of different types of sealing strips are not exactly the same. Among them, the production processes of door frame sealing strips and trunk sealing strips are basically the...

Problems solved by technology

The traditional method of butt jointing of rubber sheets is to use unvulcanized rubber to roll into rubber sheets on an open mill, and use scissors to cut square sheets with suitable length and width for jointing. The disadvantage of this method is that the roll distance of the open mill is not easy to control, so batch The thickness of the sheets cannot be accurately controlled between times, and because the rubber sheets need to be placed on a large hanger to prevent the sheets from sticking after rolling out, it is inconvenient to store, and the surface of the sheets is easily dirty due to long-term exposure to the air, resulting in joint strength. Reduced production pass rate, short shelf life of flakes, etc.

In order to solve the problem that the thickness of the sheet cannot be accurately controlled, an extrusion process can be used to obtain a sheet with a fixed thickness, but the sheet prepared by the existing rubber material through the extrusion process has a short validity period of only a few hours, which cannot meet the docking requirements The problem
