Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] The fluorine-coated antibacterial film material of the present invention is processed from polytetrafluoroethylene film, nitrile rubber sealing gasket and antibacterial compound, and the specific steps are as follows:

[0021] 1) Activation treatment of PTFE film;

[0022] Degrease the polytetrafluoroethylene film with a mixture of ethanol and ether, the ratio of ethanol and ether is 3:1, and clean it with deionized water;

[0023] Put the degreased polytetrafluoroethylene film into the acetone cleaning solution for ultrasonic vibration cleaning and activation;

[0024] The activated polytetrafluoroethylene film is vacuum-dried;

[0025] 2) In a working room with a temperature of 20-28°C and a relative air humidity of less than 65%, clean...

Abstract

The invention belongs to the machine manufacturing field and specifically relates to a processing method of a fluoride-coated antibacterial film material. The fluoride-coated antibacterial film material is formed by using a polytetrafluoroethylene thin film, a nitrile rubber gasket and an antibacterial compound; the polytetrafluoroethylene thin film is activated previously, and then coated with the antibacterial compound in a working chamber at a temperature of 20-28 DEG C and relative air humidity of less than 65%, next, the coated polytetrafluoroethylene thin film is held down and pasted to the surface of the nitrile rubber gasket, air between the pasted layers is removed, and finally, the nitrile rubber gasket pasted with the polytetrafluoroethylene thin film is dried in a drying oven at a temperature of 90 DEG C for 10 minutes. The processing method is high in production efficiency, and also high in product percent of pass, and thus wide in application prospect.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a processing method of a fluorine-coated antibacterial film material. Background technique [0002] The fluorine-coated antibacterial film material is made by bonding the PTFE film to the working surface of the rubber gasket when the rubber gasket is vulcanized. In addition to maintaining the original characteristics of the rubber gasket, it also has the advantages of small friction coefficient, good wear resistance and good self-lubrication, and is suitable for movable sealing. At present, fluorine-coated antibacterial film materials are in demand on various models and have good application prospects. The applicable working conditions (medium, temperature, pressure) depend on the properties of the coated rubber. However, due to the difficulty in the production of fluorine-coated antibacterial film materials, the production process is complicated and the quali...
