Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of oxidation resistant conductive resin coating.
Technical scheme: for achieving the above object, a kind of conductive resin coating provided by the invention, its component consists of the following composition by weight: 60～80 parts of acrylic resins, 20～35 parts of Resins, epoxy, 10～15 parts of expanded graphites, mass concentration are that 2～3 parts of the 48%EDTA disodium salt aqueous solution, 1～3 part of silane coupling agent, 15～25 parts of copper powders, mass concentration are that 30% 2～5 parts of the silver-colored solution of pin acid, 15～25 parts of carbon blacks, mass concentration are 22～36 parts of 20% ethanolic solns.
Preferably, described silane coupling agent is silane coupling agent KH-500.
The preparation process of above-mentioned conductive resin coating comprises:
(1) takes by weighing corresponding material component by above-mentioned weight part;
(2) preparation silver-plated copper powder: in the mass concentration 48%EDTA disodium salt aqueous solution, add copper powder, under 30～60 ℃, stir, the adding mass concentration is 30% the silver-colored solution of pin acid, make copper displace silver ions, allow the surface of deposition of silver at copper powder, at the silver-colored protective layer of Copper Powder Surface formation one deck densification, then with dry behind silver-plated copper powder usefulness alcohol solution dipping 15～24h, obtain conductive copper powder anti-oxidant, multilayered structure;
(3) acrylic resin, expanded graphite, Resins, epoxy acrylic resin and conductive copper powder are added in the pot of getting the raw materials ready, mix rear adding silane coupling agent, namely get coating after the stirring fully.
The EDETATE SODIUM salt brine solution that uses among the present invention, can promote silver to cover equably Copper Powder Surface, thereby make the copper powder resistance value lower, and comparatively stable, owing to wrapped up the copper powder of the multilayered structure of one deck organic acid acetic layer, remedied the inhomogeneous defective of silver-colored plating lid in the lower situation of silver content, more double-deck copper powder antioxidant property is good; The content of the acrylic resin among the present invention, copper powder and Resins, epoxy is just in time so that its conductivity is better.
Beneficial effect: the present invention in terms of existing technologies, the antioxidant property that has overcome metal in the metallic conduction coating is relatively poor, by the multilayered structure of one deck organic acid acetic layer, preferably antioxidant property are arranged at Copper Powder Surface; Can satisfy the requirement of hyundai electronics electrical equipment, have widely market outlook.
