Metal hot processing solid-state lubricant

Abstract

The invention discloses a metal hot processing solid-state lubricant, and relates to a solid-state lubricant. The metal hot processing solid-state lubricant comprises lubricants, heat-resistant components, stabilizers and preservatives. The metal hot processing solid-state lubricant particularly comprises, by weight, 25-40% of molybdenum disulfide, 20-30% of stearic acid, 10-20% of paraffin wax, 10-20% of oleic acid, 0.5-2% of sodium phosphate, 2-8% of silicone oil, and 0.5-2% of sodium benzoate. A method for preparing the metal hot processing solid-state lubricant includes placing the silicone oil, the paraffin wax and the stearic acid into a water bath kettle, and mixing and heating the silicone oil, the paraffin wax and the stearic acid with one another until the temperatures reach 80 DEG C so as to obtain first mixtures; stirring the first mixtures by an electric stirring machine, and slowly adding the molybdenum disulfide into the first mixtures after the first mixtures are uniformly stirred; sufficiently stirring the molybdenum disulfide and the first mixtures to obtain second mixtures and simultaneously adding the oleic acid, the sodium benzoate and the sodium phosphate intothe second mixtures; uniformly stirring the oleic acid, the sodium benzoate, the sodium phosphate and the second mixtures to obtain third mixtures, then pouring the third mixtures into molds and cooling the third mixtures to obtain the metal hot processing solid-state lubricant. The metal hot processing solid-state lubricant has the advantages of good mold release effect and stability, high-temperature resistance and environmental protection. Besides, the metal hot processing solid-state lubricant can be used for lubricating large complicated aluminum alloy die castings and forged pieces in the field of metal hot processing industry.

Description

technical field [0001] The invention relates to a solid lubricant, in particular to a solid lubricant for metal thermal processing. Background technique [0002] Metal thermal processing is a basic industry in the manufacturing industry. The quality of thermal processing parts directly affects the quality of subsequent processing and the quality of final products. With the progress of society and the continuous updating of industrial technology, the requirements for product quality are also increasing. The higher it is, this requires strict control of each production process of thermal processing. At present, in order to better shape the parts in metal thermal processing, different types of water-based coatings are sprayed manually or automatically in production. Die-casting is the use of manual or automatic spraying of water-based die-casting coatings in production. The purpose is to evenly coat the surface of the mold cavity to ensure that the die-casting parts can be dem...
