Inflating valve suitable for new energy automobile and production process of inflating valve

Abstract

The invention discloses a production process of an inflating valve suitable for a new energy automobile. The production process comprises the following steps of I, pretreatment of the surface of the inflating valve: firstly, preparing a mixed acid solution, and adding zinc oxide into the mixed acid solution; adding a metal nozzle body into the mixed acid solution to be washed, and removing an oxide layer on the surface of the metal nozzle body; after washing, drying in a drying oven at 40-55 DEG C till complete drying; and preparation of a rubber material: putting the raw materials in parts by weight into an internal mixer for weight pressing, carrying out weight lifting and cleaning, weight pressing, weight lifting and cleaning, discharging rubber when weight pressing is conducted to the temperature of 70-120 DEG C, carrying out roller passing for 2-7 times through an open mill, and carrying out cooling to obtain the rubber material; adding the rubber material into gasoline, stirring and mixing, dip-coating the metal nozzle body in the rubber material for 30 minutes, airing, and carrying out rubber coating and vulcanization on the dipped metal nozzle body, so as to prepare the inflating valve suitable for the new energy automobile. The rubber material of the inflating valve has the advantages of good adhesion and ageing resistance.

Description

technical field

[0001] The invention belongs to the technical field of new energy vehicles, and relates to, in particular, a valve suitable for new energy vehicles and a production process thereof. Background technique

[0002] The valve is an important part of the inner tube. It is generally made of copper and connected with the inner tube carcass as a whole through the valve rubber pad.

[0003] In the prior art, the adhesive rubber material produced by the rubber pad valve is mainly divided into two types: natural rubber and butyl rubber, which are respectively used for laminating the natural rubber inner tube and the butyl rubber inner tube. The production of the rubber pad inner tube valve needs After the two main production processes of metal valve surface pretreatment and encapsulation vulcanization, the currently used adhesive rubber has problems of insufficient adhesion and anti-aging performance.
