Abstract

The invention discloses nanometer lubricating oil used for a special coating welding wire not plated with copper and a preparation method of the nanometer lubricating oil and relates to the technical field of chemical engineering. The nanometer lubricating oil is prepared from 55-75% of palm oil, 3-16% of polytetrafluoroethylene, 4-20% of carbon black, 2-7% of graphene, 2.5-7.5% of MoS2, 0.3-5% of nanometer CuO and 0.2-1.6% of nanometer TiO2. The preparation method includes the following steps that the basic oil in the above weight percentage is added into a reaction kettle and is stirred for 1 h at the constant temperature of 75-90 DEG C, and heating stops; and the polytetrafluoroethylene, the carbon black, the MoS2, the nanometer CuO, the nanometer TiO2 and the graphene in the above mass percentage are thrown into the reaction kettle, heating is performed at the pressure intensity of 0.4-1.7 Mpa till the temperature of 50-75 DEG C is achieved, a reaction is performed for 1 h, and then only homogenizing and degassing are needed. The nanometer lubricating oil is coated on the surface of the special coating welding wire not plated with copper and guarantees good wire feeding performance, rust resistant performance and electric arc stability of the special coating welding wire not plated with copper.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a nano lubricating oil for non-copper-plated special coating welding wire and a preparation method thereof [0002] technical background [0003] In 2014, the total output of welding materials in my country reached 5.68 million tons, and the proportion of gas shielded solid welding wire has reached 35.3%. According to the report of the International Federation of Robotics (IFR), the global sales of industrial robots reached 225,000 units in 2014, among which, the sales of industrial robots in the Chinese market increased by 54%. With the development of domestic welding robots, gas shielded solid welding wire will usher in a greater development space. However, a series of environmental protection problems will arise in the production and use of copper-plated welding wire: the use of electroplating or electroless plating in production, the use of chemicals such as strong ...
