Problems solved by technology

[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 that of carbon black, and the compression deformation is generally poor, and the processing performance is not good. , so the development of colored rubber materials that can meet the requirements of oil resistance, low temperature and low pressure change has always been in great demand

Embodiment 1-4

[0023] The preparation method of the colored throttle oil-resistant rubber material of the present invention is as follows: 1) putting nitrile rubber into a banbury mixer for masticating, and parking for use; 2) putting the masticated rubber material into a banbury mixer, and then adding reinforcement agent, calcined hard clay, environmentally friendly plasticizer, stearic acid, fully stirred, mixed evenly, and parked for use; 3) Put the banburyed rubber into the internal mixer, and then add sulfur and the remaining accelerator, zinc oxide , processing aids and other raw materials for banburying; 4) Extrude and granulate through an extruder to obtain a colored throttle valve oil-resistant rubber compound.

[0024] See Table 1 for the names and proportioning of raw materials in the rubber compound of the present invention.

Abstract

The invention discloses a colored throttle valve oil-resistant rubber material, which comprises the following components: nitrile rubber NBR 2865, nitrile rubber NBR 1965, a reinforcing agent ZJ355, calcined hard pottery clay, an environment-friendly plasticizer J288, zinc oxide, stearic acid, an antioxidant KY405, an antioxidant RD, a processing aid WB42, polyethylene glycol PEG4000, a coupling agent HP669, sulfur S, an accelerator DM, accelerator DPTT and an accelerator TT. The rubber material has the advantages of excellent oil resistance, favorable low-temperature properties, low permanentcompression set and favorable basic physical and mechanical properties, and is suitable to be used as a colored oil-resistant rubber material.

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...
