Abstract
The invention relates to the field of copper wire machining, in particular to copper wire annealing liquid. The copper wire annealing liquid comprises the following components of, by weight part, 10-20 parts of base oil, 15-25 parts of lubricant, 20-30 parts of palm oil, 10-20 parts of ricinolein, 1-5 parts of metal antioxidant, and the balance distilled water. The copper wire annealing liquid islow in production cost and reasonable in compounding ratio, plasticity and flexibility of a copper wire are improved, strength of the copper wire is improved from previous 240 mpa to 300-400 mpa, theelongation rate of the copper wire is increased by 8%-10%, and the antioxidant degree of the copper wire is increased from previous 10 days to about 35 days.
Description
technical field [0001] The invention relates to the field of copper wire processing, in particular to a copper wire annealing liquid. Background technique [0002] Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize size, and reduce deformation and cracks. Tendency to refine the grain, adjust the structure, and eliminate the defects of the structure; to be precise, annealing is a heat treatment process for materials, including metal materials and non-metal materials. During the annealing process, an annealing liquid is needed, and most of the existing annealing liquids have certain defects, which make the copper wire insufficient in plasticity, easily oxidized, poor in flexibility, low in strength, and low in elongation.
