Problems solved by technology

However, these products can only increase the viscosity of the product, but cannot improve the lubricating performance of the product, so additional oiling agents are required, such as trimethylolpropane oleate, pentaerythritol oleate, chlorinated paraffin, etc.
These are petroleum synthetic products, not environmentally friendly, and difficult to biodegrade
Moreover, the performance of the existing oil-based agents cannot fully meet the production needs of the product

Abstract

The invention discloses wind-blown polymerized vegetable oil as well as a preparation method and application thereof. Natural vegetable oil is used as a raw material, a composite catalyst is added, anormal-pressure reaction is carried out for 8-14 hours at the temperature of 130+ / -5 DEG C, air is continuously blown in the reaction process, the wind-blown polymerized vegetable oil is obtained, andthe kinematic viscosity of the obtained wind-blown polymerized vegetable oil can be regulated and controlled by controlling the reaction time. The wind-blown polymerized vegetable oil disclosed by the invention has excellent lubricating property, adhesiveness and chemical stability as well as excellent protectiveness to metal surfaces, can meet the requirements of relatively high lubricating property and kinematic viscosity, and is particularly suitable for being applied to lubricating oil or metal processing industry.

Description

technical field [0001] The invention belongs to the field of new natural environment-friendly lubricating materials, and in particular relates to a wind-blown polymerized vegetable oil and its preparation method and application. Background technique [0002] Domestic research on environmentally friendly lubricants is still in the initial stage of exploration, and there is still a big gap with practical applications. Judging from the research on vegetable oil as lubricating oil and metal processing additives in recent years, the development of new and efficient multifunctional lubricating oil and metal processing fluid additives has a good development prospect. [0003] At present, the chain polymers that can increase the viscosity in lubricating oils or metalworking fluids are commonly used polyethylene n-butyl ether, polyisobutylene, ethylene-propylene copolymer, sodium polyacrylate, etc., and their molecular weights range from tens of thousands to several million. .
