Problems solved by technology

Lanthanum borate is a newly developed lubricating oil additive with relatively good performance, but most of the nano-lanthanum borate on the market is synthesized by grinding and pulverizing methods and physical methods. This kind of nanoparticles has large surface energy and high polarity. Agglomerated and not easy to disperse, can not give full play to the characteristics of nano-lanthanum borate, which also restricts the promotion and use of nano-lanthanum borate

Abstract

The invention provides a nano lanthanum borate antifriction agent and a preparation method and application thereof. The preparation method comprises the following steps: carrying out displacement reaction on borax, a phosphate coupling agent and lanthanum chloride, and crystallizing, filtering and cleaning sequentially after the reaction is finished to obtain nano lanthanum borate; and dehydratingand esterifying the nano lanthanum borate, heavy alkyl benzene and a hyperdispersant, and naturally cooling to normal temperature after the reaction is finished. The invention also provides the application of the nano lanthanum borate antifriction agent in preparing lubricating oil. The antifriction agent changes the surface characteristics of a material through the heavy alkylbenzene and the hyperdispersant, has excellent abrasion resistance, antifriction and extrusion load performance, does not pollute the environment and does not corrode metals. Compared with the traditional antifriction agent, the nano lanthanum borate antifriction agent can make the service life of the lubricating oil longer and can better protect the metal surface from abrasion under harsh conditions.

Description

technical field [0001] The invention relates to a friction reducer and a preparation method thereof, in particular to a nano-lanthanum borate friction reducer and a preparation method and application thereof. Background technique [0002] Borate additives have excellent tribological properties and do not corrode metals, but their disadvantages are poor oil solubility, cannot form a stable solid-oil dispersion system in oil, and cannot effectively enter the friction interface to play a role. At present, commercial borate lubricating oil friction reducers mainly rely on the addition of a large amount of surfactants to ensure that borate particles are evenly suspended in the oil. Lanthanum borate is a newly developed lubricating oil additive with relatively good performance, but most of the nano-lanthanum borate on the market is synthesized by grinding and pulverizing methods and physical methods. This kind of nanoparticles has large surface energy and high polarity. Agglomera...
