NOVELTY - Lubricant comprises 50-88 pts. wt. polya-olefin, 10-25 pts. wt. polyisobutylene, 0.2-2 pts. wt. graphene, 5-10 pts. wt. calcium petroleum sulfonate, 0.5-10 pts. wt. detergent,5-15 pts. wt. alkylnaphthalene sulfonate, 0.2-1.5 pts. wt. phosphate, and 1-15 pts. wt. fumed silica. USE - Lubricant for internet of things artificial intelligence device. ADVANTAGE - The lubricant has stable performance due to stabilized chemical balance of each component. It is suitable for lubrication of internet of things artificial intelligence equipment under wide temperature conditions (-30-300 degrees C working environment) and complex and harsh environments. The lubrication cycle of the lubricant is long, the equipment does not need maintenance and maintenance during use, and it is not necessary to change the lubricant to meet the requirements of full-life lubrication. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing lubricant, which involves uniformly mixing graphene, fumed silica and polya-olefin, and then heating the mixture to 40-60 degrees C, and then adding the remaining materials and stirring the reaction at a 40-60 degrees C for more than 2 hours.
