Non-metal conductor used for button switches and preparation method of non-metal conductor

Abstract

The invention relates to the technical field of button switches, in particular to a non-metal conductor used for button switches. The non-metal conductor comprises the following raw materials in partsby weight: 75-85 parts of polymer elastic particles, 23-31 parts of polydodecalactam, 2-8 parts of an alkali metal salt, 85-105 parts of a conductive material, 15-20 parts of carbon black and 2-4 parts of an active agent. The polymer elastic particles enable the conductor to have good elasticity, and the surfaces of the polymer elastic particles are coated with a vulcanizing agent, so that the conductive elastomer has a low percolation value. An organic polymer polyelectrolyte is prepared by complexing and coordinating alkali metal ions with a polydodecactam polyether block, and the polyetherblock (C-O-C) generally have flexibility and can form an associated matter with an electron acceptor or certain inorganic electrolytes. Through addition of an auxiliary conductive agent, surface activity of the polymer elastic particles can be improved and conductivity is improved. The non-metal conductor has outstanding substantive characteristics and remarkable progress.

Description

technical field [0001] The invention relates to the technical field of push button switches, in particular to a non-metallic conductor used for push button switches and a preparation method thereof. Background technique [0002] The push button switch refers to a switch that uses a button to push the transmission mechanism to make the moving contact and the static contact press on or off and realize the circuit switching. The push button switch is a kind of master electrical appliance with simple structure and wide application. In the electrical automatic control circuit, it is used to manually send control signals to control contactors, relays, electromagnetic starters, etc. This kind of button switch is often used in factories. The button switch is mainly composed of button caps, fixed contacts, moving contacts, etc. The fixed contacts are usually made of metals, metal alloys and semiconductors, and the button switches are turned on and off by pressing. However, due to th...

In the electrical automatic control circuit, it is used to manually send control signals to control contactors, relays, electromagnetic starters, etc. This kind of button switch is often used in factories. The button switch is mainly composed of button caps, fixed contacts, moving contacts, etc. The fixed contacts are usually made of metals, metal alloys and semiconductors, and the button switches are turned on and off by pressing. However, due to the limitation of the elastic modulus of metals, metal alloys and semiconductor materials, their flexibility is poor and mechanical The magnitude of the change is small, and the sensitivity is poor, the structure is complex, and the manufacturing cost is high. After a long time of use, the fixed contact will be deformed, and the contact with the moving contact will be poor or not, which will affect the production. Therefore, we propose a method for Non-metallic conductor used in push button switch and preparation method thereof
