Cold extrusion forming lubricant for low carbon steel part used for automobile and preparation method thereof

Abstract

The invention discloses a cold extrusion forming lubricant for a low carbon steel part used for an automobile. The main body of the lubricant comprises the following components by mass: 1% to 3% of an oiliness additive, 0.3% to 0.8% of a preservative, 3% to 6% of an antifriction agent, 0.1% to 0.5% of an antioxidant, 0.2% to 0.5% of a defoaming agent, 2% to 5% a dispersion agent, 1% to 3% of a cleaning agent, 0.1% to 0.5% of an active agent, 0.3% to 1.0% of an extreme pressure agent and 1% to 4% of an adsorbent, with the balance being deionized water. The invention also discloses a preparation method for the cold extrusion forming lubricant for the low carbon steel part used for the automobile. The lubricant and the preparation method provided by the invention have the advantages of low energy consumption, low pollution, low emission, etc.

Description

technical field [0001] The invention relates to a lubricant and a preparation method, in particular to a lubricant for cold extrusion of low-carbon steel parts for automobiles and a preparation method thereof. Background technique [0002] As the energy crisis becomes more and more serious, people will pay more attention to the quality of the environment, and promote the development of industries such as automobiles in the direction of light weight, high speed, and stability. Higher requirements are put forward, and the production of parts is developing in the direction of high efficiency, high quality, refinement, energy saving, and material saving. Due to the obvious advantages in the performance and forming process of metal cold extrusion products, it has developed rapidly in the automotive field, and the material utilization rate of cold extrusion parts has reached more than 80%. The material utilization rate increased to 92% during cold extrusion forming, and after t...

Problems solved by technology

Traditionally used lubricants mainly include liquid lubricants (mineral oil, vegetable oil, animal oil, emulsion, etc.), solid lubricants (graphite, molybdenum disulfide, soap and wax lubricants, etc.), and have the following disadvantages: 1. Waste The liquid volume is large and extremely difficult to handle; 2. The operating environment is harsh and the smoke is toxic, which affects the health of workers; 3. The waste liquid and gas seriously damage the ecological environment; 4. The surface quality of cold extrusion parts is poor and other problems
