Abstract

The invention discloses an electromagnetic self-operated pressure-sensitive structure contact and a manufacturing method thereof. The core technology of the invention is a specially-made magnetic core; the magnetic core is composed of three components, namely pressure-sensitive colloid which is used as a matrix and has a methyl polysiloxane typical structure, soft magnetic material iron-nickel alloy which has an electromagnetic induction function, and a aluminum core silver shell particles which are used for improving the conductivity of a core body. The three components are uniformly distributed under the action of the pressure-sensitive adhesive body and promote each other, so that the 180-degree peel strength of 1.1 kN/m, the shear strength of about 0.85 MPa and the initial conductivityof 2000S/m-2500S/m (the initial conductivity can be improved to about 3500 S/m after being pressed) of the whole pressure-sensitive adhesive are obtained. The electromagnetic self-operated pressure-sensitive structure contact is self-actuated, good in fitting performance, increased in conductivity after actuation, resistant to impact and resistant to corrosion.

Description

technical field [0001] The invention relates to the technical field of electrical devices, in particular to a method for manufacturing an electromagnetic self-supporting pressure-sensitive structural contact. Background technique [0002] Silicone rubber has both the heat resistance of inorganic polymers and the flexibility of organic polymers. Its unique high and low temperature resistance makes it widely researched and applied in the field of cutting-edge defense technology. Composite conductive rubber prepared with silicone rubber as the base material and added with conductive fillers has the advantages of good formability, adjustable conductivity, high and low temperature resistance, and aging resistance. Based on the above advantages, conductive rubber has been widely used in military, electronics, medical and other fields. Commonly used conductive fillers mainly include carbon-based materials such as carbon black, graphite, carbon fiber, and carbon nanotubes, as well ...
