Description

technical field

[0001] The invention belongs to the field of rubber, and in particular relates to a color throttle oil-resistant rubber material. Background technique

[0002] The throttle is a controllable valve that controls air entering the engine. It is connected to the air filter on the top and the engine block on the bottom. It is called the throat of the car engine. Whether the car can accelerate flexibly has a lot to do with the cleanliness of the throttle valve. The rubber parts connected to the throttle valve include seals, vacuum tubes, etc. Since the throttle valve is connected to the engine, air filter device, etc., in order to ensure good air tightness, it needs to have good oil resistance and low compression deformation.

[0003] Due to the improvement of customers' requirements for product appearance, many original black rubber materials are required to be made into colored rubber materials, but the reinforcing performance of white fillers is far inferior to...
