Abstract

The invention discloses a copper antioxidant and a preparation method thereof and belongs to the technical field of metal anti-oxidation. According to the copper antioxidant and the preparation method thereof, the copper antioxidant is good in protective property and does not corrode for a long time and does not fade. The copper antioxidant is characterized in that the copper antioxidant per liter contains the following ingredients by weight: 50-100g of hydroxy ethylidene diphosphonic acid, 50-100g of ethanol, 80-150g of hydrogen peroxide, 20-40g of a corrosion inhibitor, 10-20g of isothiocyanate, 8-15g of alkyl sulfate, 10-20g of sodium molybdate, 8-12g of sodium tripolyphosphate and the balance of water. The preparation method of the copper antioxidant comprises the steps: (1) weighing all the ingredients; (2) putting the ingredients weighed in the step (1) in a reaction vessel, adding water until the volume is 1L, and then, stirring for 20-60 minutes at the temperature of 40-50 DEG C, thereby obtaining the copper antioxidant.

Description

technical field [0001] The invention relates to an antioxidant, in particular to a copper antioxidant and belongs to the technical field of metal oxidation resistance. Background technique [0002] Copper metal has good luster, and its electrical conductivity is almost equal to that of silver, but the price is only one-twentieth of silver. Therefore, in terms of cost performance, copper powder is an ideal conductive filler. These characteristics of copper powder make it widely used in conductive adhesives, conductive plastics, conductive coatings and other fields. However, the fine copper powder has a large specific surface area, active chemical properties, and is prone to oxidation in the air, resulting in darkening of the material and poor decoration, and the oxide is an insulator, which makes it difficult for conductive materials to be used for a long time. Maintain good electrical conductivity. Therefore, how to prevent copper powder from being oxidized during the prep...
