Abstract

The invention belongs to the field of electronic materials and relates to a preparation method of a soybean-fiber composite fuse. The preparation method has the characteristic of metallizing the surface of soybean fiber and comprises the following specific processes: cleaning the soybean fiber, modifying the surface, activating the surface and carrying out chemical copper plating and the like. The soybean-fiber composite fuse has the following advantages: (1) the use of toxic metals such as lead, tin and chromium is avoided; (2) the soybean fiber is protein fiber, belongs to renewable resources and is green and environment-friendly; (3) the content of metal copper is less, and the cost is low, so that the soybean-fiber composite fuse is a resource-saving type material; and (4) the application space of high-melting-point metals in the temperature fuse is expanded. The soybean-fiber composite fuse can be used for high and new-technology products such as flexible electronic devices and wearable electronic products, and is wide in market prospect.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to a preparation method of a soybean fiber composite fuse. Background technique [0002] The core of the thermal fuse is the fusible alloy. The traditional fusible alloy is a ternary or quaternary alloy composed of Sn, Pb, Bi, Cd and other metals. By adjusting the composition of the metal, alloy wires with different melting points can be obtained. People have mastered the Pb-Sn-Bi and Pb-Sn-Cd ternary phase diagrams, according to the phase diagrams, it is easy to prepare fusible alloys with melting points from 65°C to 300°C, so as to produce temperature for different environments and applications fuse. With the development of science and the progress of society, clear requirements and indicators have been put forward for the environmental protection performance of electronic products, and electronic products with green certification marks have become more a...
