Problems solved by technology

[0004] However, because butyl stickers are made of polymer materials such as isobutyl rubber, their cost is relatively high, and butyl stickers also need to be injected into the sealing strip through an off-line glue machine when in use. Complicated, special glue injection machine is needed for artificial glue injection, and there is also the problem of low production efficiency

Abstract

The invention provides a water-stopping sponge rubber material, a preparation method thereof, a sealing strip and a preparation method of the sealing strip and an automobile, the water-stopping spongerubber material is prepared from the following components in parts by weight: 100 parts of ethylene-propylene-diene monomer v8600, 20-30 parts of terpene resin, 20-30 parts of brominated butyl rubber, 6-10 parts of zinc oxide, 1-3 parts of stearic acid, 1-3 parts of polyethylene glycol, 30-50 parts of carbon black HS45, 70-90 parts of R-2291 paraffin oil, 6-10 parts of an OBSH foaming agent, 6-10parts of an AC foaming agent, 5-7 parts of foaming assistant K4-P, 1.5-2.5 parts of sulfur, 7-12 parts of hygroscopic agent CaO and 6-10 parts of an accelerant. The water-stopping sponge rubber material disclosed by the invention has the characteristics of low density, low damping and high viscosity, can be conveniently arranged in a sealing sleeve, has good water stopping performance, and has very good practicability.

Description

technical field [0001] The present invention relates to the technical field of preparation of sealing strips, in particular to a water-stop sponge compound used for sealing strip products, the invention also relates to a preparation method of the water-stop sponge compound, and a water-stop sponge compound applied thereto Sealing sleeve and preparation method thereof. In addition, the present invention also relates to an automobile equipped with the weather strip. Background technique [0002] There are a large number of sealing strips installed on the car. Take the trunk door sealing strip as an example. Most of the trunk door sealing strips are installed on the sheet metal protruding from the trunk position of the body. The fit of the strip and the trunk door plays a sealing effect to prevent external wind, rain and dust from entering the car, keep the car clean, and reduce the vibration of the trunk door during the driving process of the car, extending the length of the ...
