Problems solved by technology

[0003] However, the current dust cover for the plug-in port of new energy vehicles has many shortcomings due to its unreasonable formula: for example, it is rare to consider both its electrical performance and oil resistance in the transition from traditional vehicles to new energy vehicles. The weather resistance performance will lead to the loss of the function of the dust cover for the plug-in port of the new energy vehicle, which seriously affects the use of the new energy vehicle
[0004] At the same time, at present, the dust cover for the plug-in port of new energy vehicles has also seriously affected the performance of the dust-proof cover for the plug-in port of new energy vehicles due to the irrationality of its preparation method, and the process of the whole preparation method is complicated and difficult. Meet the needs of rapid vulcanization and mass production of injection machines

Embodiment Construction

[0026] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings, however, the contents of the drawings and the specific implementation manner are not intended to limit the present invention.

[0027] The invention relates to a dustproof cover for a new energy vehicle plug-in port and a preparation method thereof. In the present invention, the material for preparing the dust cover consists of the following components by weight: 10-100 parts of nitrile rubber, 5-100 parts of nitrile rubber / polyvinyl chloride blend, 10-100 parts of N550 carbon black 100 parts, 10-100 parts of nano kaolin, 10-100 parts of activated calcium carbonate powder, 1-50 parts of dioctyl terephthalate and 8-12 parts of vulcanizing agent.

[0028] Among them, nitrile rubber is prepared by emulsion polymerization of butadiene and acrylonitrile. Nitrile rubber has excellent oil resistance, high wear resistance, good heat resistance, goo...

Abstract

The invention relates to a dustproof cover of a charge port of a new energy vehicle and a preparation method thereof. The dustproof cover is prepared from, by weight, 10-100 parts of nitrile butadienerubber, 5-100 parts of blend nitrile butadiene rubber / polyvinyl chloride, 10-100 parts of N550 carbon black, 10-100 parts of nano-kaolin, 10-100 parts of active CaCO3 powder, 1-50 parts of dioctyl terephthalate, and 8-12 parts of a vulcanizer. The dustproof cover is excellent in dielectic breakdown voltage performance, has excellent weather resistance, anti-tearing effect and flame-retarding property, and has great rebound resilience.

Description

technical field [0001] The invention belongs to the field of vehicle equipment, and relates to a dust cover and a preparation method thereof, in particular to a dust cover for a new energy vehicle plug-in port and a preparation method thereof. Background technique [0002] The plug-in port of new energy vehicles must be equipped with a dust cover to prevent dust and other pollutants from entering the plug-in port and affecting charging and use. Existing dust covers for plug-in ports of new energy vehicles are usually made of rubber. However, due to its special purpose, the dust cover for the plug-in port of new energy vehicles requires that the rubber dust cover should have good breakdown voltage resistance, good fuel resistance, weather resistance, tear resistance, and good return elastic properties. [0003] However, the current dust cover for the plug-in port of new energy vehicles has many shortcomings due to its unreasonable formula: for example, it is rare to conside...
