Abstract

The invention discloses a production technology of a hexagonal-boron-nitride-modified wire drawing lubricant for a varnished wire. The production technology comprises the following steps that a, hexagonal boron nitride powder is added to deionized water to obtain a mixture; b, the mixture is heated to 50-70 DEG C and stirred for 8-12 minutes to obtain mixed liquid; c, (0.8 to 1.4) to 10 in parts by weight of the mixed liquid and copper wire emulsifying lubricating oil are subjected to shearing on a shear emulsifying machine for 25-35 minutes, and hydrous emulsified liquid is obtained; d, 3.0-11.0 % of the hydrous emulsified liquid is added to a wire drawing lubricant pool/tank containing wire drawing lubricant oil, and wire drawing emulsified liquid is obtained through recycling of a circulating water pump of the wire drawing lubricant pool/tank; and e, the pH value of the wire drawing emulsified liquid is adjusted to be 8.0-9.0, and a finished product is obtained. The production technology of the hexagonal-boron-nitride-modified wire drawing lubricant for the varnished wire has the characteristics that the long-lasting anti-oxidant property is good, the viscosity is low and the lubricating effect is good.

Description

technical field [0001] The invention relates to a production process of wire drawing lubricant for enameled wire, in particular to a production process of hexagonal boron nitride modified wire drawing lubricant for enameled wire. Background technique [0002] Wire drawing is an essential process in the processing of wires, cables, magnet wires and other cables. In the wire drawing process, a wire drawing lubricating fluid is required. The basic function of the wire drawing lubricating fluid is first to reduce the friction in the wire drawing deformation area and reduce the energy consumption during wire drawing; secondly, to cool and clean the wire drawing wire, take away the metal powder, and avoid metal The powder sticks to the surface of the mold to improve the surface quality of the metal being machined. In the actual wire drawing production process, the conventionally used wire drawing lubricating fluid has high viscosity during use, is easy to oxidize, and has a fast ...
