Abstract

The invention discloses a copper antioxidant and a preparation method thereof, aiming to provide a copper antioxidant with good protection, no corrosion and no fading over time, and a preparation method thereof. The technical points are: the copper antioxidant per liter Contains the following components: hydroxyethylidene diphosphonic acid 50-100g, ethanol 50-100g, hydrogen peroxide 80-15 corrosion inhibitor 20-40g, isothiocyanate 10-20g, alkyl sulfate 8-15g , sodium molybdate 10-20g, sodium triphosphate 8-12g, surplus is water; The preparation method of this copper antioxidant: 1) take each component; 2) step 1) the component that takes by weighing is put into reactor , add water to 1L, and then stir at 40-50°C for 20-60 minutes to obtain copper antioxidant; it belongs to the technical field of metal anti-oxidation.

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...
