Abstract

The invention discloses a high-performance pore-free exothermal flux for a copper conductor. The high-performance pore-free exothermal flux for the copper conductor includes the following raw materials of, by weight, 70-80 parts of spherical copper oxide with particle size of 50-80 meshes, 11-18 parts of aluminite powder with particle size of 200 meshes, 4-8 parts of fluorite powder with particlesize of 200 meshes and 0.5-1.5 parts of yttria oxide with particle size of 60-80 meshes. A preparation method of the exothermal flux includes the following steps that the spherical copper oxide with particle size of 50-80 meshes, the aluminite powder with particle size of 200 meshes, the fluorite powder with particle size of 200 meshes and yttria oxide powder with particle size of 60-80 meshes arefirstly prepared, the prepared spherical copper oxide, aluminum powder, fluorite powder and yttrium oxide powder are then added into a high-speed mixer to be uniformly mixed, then drying is carried out to constant weight, vacuum sealing and storing are carried out, and the exothermal flux is prepared to obtain. According to the high-performance pore-free exothermal flux for the copper conductor,the problems of difficult separation between a base and welding slag, welding slag adhering to the joint surface and honeycomb pores of a welding joint in a copper welding process are solved.

Description

technical field [0001] The invention relates to the technical field of copper material welding, in particular to a high-performance non-porous exothermic flux for copper conductors. Background technique [0002] The service life of the grounding system and the value of grounding resistance are crucial to the operation of the entire power grid. With the continuous expansion of power, especially the construction of ultra-high voltage power grids and ultra-high voltage power grids, the capital investment in power facilities is very large. Grounding is a basic concealed project. The traditional method is to use hot-dip galvanized materials as the grounding grid, while the ultra-high voltage power grid and UHV power grid are designed to have a long service life and require high electrical stability. In this case, a large number of copper materials are used as the grounding grid, which has a long service life and a firm and stable grounding system. [0003] Copper welding has al...
