NOVELTY - Water-soluble titanium alloy hot rolling lubricant having multi-particles synergistic effect comprises 6-9 wt.% phosphate, 0.05-0.1 wt.% graphene, 1-3 wt.% oxide nano powder, 1-2 wt.% polyvinylpyrrolidonen and 86-92 wt.% deionized water, where the lubricant is solid-liquid mixed lubricant. USE - Used as water-soluble titanium alloy hot rolling lubricant having multi-particles synergistic effect. ADVANTAGE - The titanium alloy hot rolling lubricant: has excellent stability, excellent anti-friction and abrasion resistance properties and excellent lubricating performance during hot rolling; and maintains lubricating performance for long time during rolling. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing water-soluble titanium alloy hot rolling lubricant, comprising (i) adding phosphate into deionized water at 40 degrees C using a magnetic stirrer to obtain primary solution, (ii) quickly heating primary solution to 80 degrees C by the temperature control system of the magnetic stirrer, controlling the stirring speed to 1100 revolutions/minute, mixing graphene aqueous dispersion with primary solution under stirring to obtain secondary solution, (iii) adding polyvinylpyrrolidone into secondary solution at a stirring speed of 1-2 g/per 100 ml liquid and stirring at a stirring speed of 1100 revolutions/minute for 1.5 hours to obtain mixed solution, (iv) cooling step (iii) product to 35 degrees C, then adding into oxide nano powder and stirring for 30 minutes, and (v) subjecting step (iv) product to ultrasonic treatment at a power of 1500 W to obtain final product.
