Preparation method for anti-wear reagent at extreme pressure and application in full synthetic water-based molding liquid

Abstract

The invention discloses a preparation method for an anti-wear reagent at extreme pressure and an application in full synthetic water-based molding liquid and relates to the field of metal forming lubricant. The anti-wear reagent at extreme pressure comprises the following components by weight percent: 70%-85% of base liquor, 10%-19% of oiliness agent, 2.3-8% of anti-wear reagent at extreme pressure and 2-8.7% of antirust agent. The full synthetic water-based molding liquid is prepared according to the following steps: weighting mixture of water and ethylene glycol, water-soluble polyether, benzotriazole and phthalocyanine lanthanum modified graphene oxide compound; putting the weighted mixture of water and ethylene glycol into a stirring reaction kettle; adding water-soluble polyether; heating to 60 DEG C in water bath and continuously stirring till the solution in kettle is transparent and uniform, and then stopping heating; adding benzotriazole and phthalocyanine lanthanum modified graphene oxide compound into the acquired solution in turn, wherein another reagent shall be added after uniformly stirring and mixing each previously added component; stirring 10-30 minutes till uniformly mixing after adding all the components.

Description

technical field [0001] The invention relates to the field of metal forming lubricants, in particular to a preparation method of an extreme pressure antiwear agent and its application in a fully synthetic water-based forming fluid. Background technique [0002] Since the advent of water-based metalworking fluids in the 1940s, due to the incomparable cooling performance and low cost of oil-based fluids, it has attracted widespread attention in the market, resulting in the original oil-based metalworking fluids being gradually replaced by water-based metalworking fluids. (especially fully synthetic water-based metalworking fluid) instead. [0003] Water-based metalworking fluids have gone through the process of developing from emulsions to synthetic fluids and then to microemulsions in western developed countries, and microemulsions have been developed and applied unprecedentedly. In my country, metalworking fluids are still dominated by emulsions. In the 1980s, there was an u...

Problems solved by technology

[0005] Because traditional extreme pressure antiwear agents face various environmental protection problems, and have poor multifunctionality, anti-oxidation, anti-cleaning properties, and weak repair functions, people have paid more attention to rare earths and their compounds in recent years.
