Problems solved by technology

[0005]However, for a long time, the domestic market has been mainly occupied by skateboard lubricants imported from Japan. The main reason is that the quality of domestic skateboard lubricants is not perfect enough
It is mainly manifested in several aspects: first, the oxidation resistance is poor, and the lubricating coating is quickly lost due to air oxidation during the working process of the skateboard, which leads to the failure of the number of slides to meet the requirements; second, the lubricant coating of the skateboard Covered on the surface of the skateboard, the drying speed is slow, especially in winter, which affects the actual production efficiency of the skateboard; third, the paint has poor suspension and is prone to sedimentation, so the storage life is much lower than similar products imported from Japan

Abstract

The invention discloses a high-temperature lubricating agent and a preparation process thereof. The high-temperature lubricating agent comprises the following components in parts by weight: 25-35 parts of graphite micro powder, 0.1-0.5 part of acid dispersant, 5-10 parts of xanthan gum, 2-10 parts of hexagonal boron nitride, 0.5-1 part of lithium-based bentonite, 10-20 parts of aluminium dihydrogen phosphate powder, 0.1-0.5 part of kathan and 90-95 percent of purified water, wherein the surface of the graphite micro powder is subjected to nickel-plated treatment. The preparation process for preparing the high-temperature lubricating agent comprises the following steps of: preparing nickel-coated graphite micro powder; and preparing a pre-mixed solution; and adding the hexagonal boron nitride, the graphite micro powder obtained in the first step and the pre-mixed solution prepared in the second step into a ball milling machine to obtain the high-temperature lubricating agent. The invention aims at providing the high-temperature lubricating agent capable of providing high-temperature oxidation resisting protection for the surface of a sliding plate and the preparation process of the high-temperature lubricating agent.

Description

Technical field [0001] The present invention involves a high -temperature lubricant, especially for a high -temperature sliding plate lubricant material for sliding water in a steelmaking continuous casting equipment, which is a high -temperature lubricant field. Background technique [0002] In the steelmaking connection equipment, sliding water inlet is one of the most critical components. Its role is to control the flow of the steel water in the process of casting.Influence.With the improvement of the quality requirements of steel metallurgy at home and abroad, higher technical requirements have also been put on the performance of sliding water.Skateboarding is one of the important components of sliding water inlet. Its shape is oval, and the surface of the plate has a consistent round hole. When the round holes of the two skateboards are aligned, the steel water can flow out of the hole.In the steel bag, the skateboard is the most important component to control steel water fl...
