Abstract

The invention discloses a heat-resistant nano-silver conductive paint and a manufacturing process thereof. The heat-resistant nano-silver conductive paint comprises the following components in parts by weight: polypropylene random, heat-resistant polyethylene, diisopropylbenzene peroxide, a viscosity modifier, tackifying resin, graphite powder, silver powder and nano-silver wire dispersion liquid. Nanoscale conductive silver wires are mixed into water-soluble or oil-soluble resin, so that the conductivity of the resulting paint is greatly improved; the heat-resistant polyethylene and the tackifying resin are mixed into the solution, so that the pain has the characteristics of high adhesion and heat resistance; the superconductivity of the graphite powder and the silver powder is matched with the nanoscale conductive silver wires, so that the paint is low in resistivity and has superconductivity. The preparation method is simple, the added auxiliaries are few, the raw materials are cheap and easy to obtain, the reaction conditions are mild, the pollution is free, and the method is suitable for mass production.

Description

technical field [0001] The invention relates to the field of conductive coatings, in particular to a heat-resistant nano-silver conductive coating and a manufacturing process thereof. Background technique [0002] Conductive coating is a special functional coating developed rapidly along with modern science and technology, and has a development history of about half a century. In 1948, the United States published a patent for making conductive adhesive from silver and epoxy resin, which was the earliest disclosed conductive paint. my country also began to study and apply conductive coatings in the 1950s. In recent years, conductive coatings have been applied in various military and civilian industrial fields such as electronics, electrical appliances, aviation, chemical industry, and printing. Correspondingly, the theoretical research on conductive coatings has also developed rapidly, and has promoted the increasingly mature and perfect application technology. [0003] Na...
