Problems solved by technology

There are serious quality problems in the radiator plate rubber sealing strip assembly in the domestic vehicle engine cooling system, such as rubber tear strength, elongation at break, tear strength, compression deformation, high temperature aging resistance and cooling liquid aging resistance Therefore, most of the rubber parts used in domestic medium and high-end cars still use imported parts.
This has greatly increased the cost of automobile production and restricted the development of my country's automobile industry.

Abstract

The invention provides a radiator plate-typed sealing strip assembly in an automobile engine cooling system and a manufacturing process thereof. The radiator plate-type sealing strip assembly in the automobile engine cooling system consists essentially of EPDM rubber, carbon black and the like; the manufacturing process mainly comprises the steps of: synthesizing rubber, sulfur treatment, trimming, two-process sulfur treatment, testing and putting into storage. The radiator plate-type sealing strip assembly manufactured by the process has good tensile strength at break, good elongation at break, good tear strength, good compression deformation and time effect of high-temperature resistance and cooling fluid resistance, thus ensuring good sealing property.

Description

technical field [0001] The invention relates to a rubber component for a vehicle and a manufacturing process thereof, in particular to a radiator plate rubber sealing strip component used in a vehicle engine cooling system and a manufacturing process thereof. Background technique [0002] Judging from the development trend of the domestic automobile industry, the automobile engine cooling system has been using radiators for cooling. At present, the improvement of radiators has been carried out in aspects such as heat sinks and circulation methods, and rubber products have been used for the seals connecting the plastic shells and aluminum and copper shells, and no other alternative products have appeared. Some just make some adjustments in product structure and rubber material selection. With the continuous prosperity of the car market, the use of radiators has been increasing year by year, especially with the global integrated procurement, the market competition has become ...
