Abstract

The invention provides a nylon auxiliary agent oil and a preparation method and a use thereof, and is used for solving the problems that the dispersion of an added powder lubrication material is not good and thus the product strength and wear resistance are affected during preparation of casting nylon in the prior art; the nylon auxiliary agent oil includes the following components by weight: 88-94 wt% of lithium 12-hydroxystearate thickened lubricating grease, 1.0-2.0 wt% of an antioxidant, 1.0-2.0 wt% of modified montmorillonite, 3.0-5.0 wt% of an active bright yellow K6G, and 1.0-3.0 wt% of a toughening agent. The nylon auxiliary agent oil provided by the invention is mainly used for preparation of the casting nylon, and the impact strength and temperature resistance of the casting nylon prepared after the nylon auxiliary agent oil is added are greatly improved; in addition, the nylon auxiliary agent oil provided by the invention has good self lubrication performance, the friction coefficient of the casting nylon prepared after the nylon auxiliary agent oil is added is greatly reduced, the noise is low and the service life is long when the casting nylon is in use, and oil-free lubrication can be achieved.

Description

Technical field [0001] The invention relates to the technical field of polymer synthetic materials, in particular to a nylon auxiliary oil and its preparation method and application. Background technique [0002] Casting nylon is to directly polymerize the caprolactam monomer under the action of strong alkali (such as NaOH) and other co-catalysts to obtain the blank of the product. Because the polymerization and molding process are combined, the molding is convenient and the equipment investment is small. , It is easy to manufacture large machine parts such as tens of kilograms of gears, turbines, bearings, etc. The mechanical and physical properties of cast nylon are much higher than nylon. [0003] The existing domestic and foreign preparation process of cast nylon is mainly modified nylon material with solid inorganic powder, such as patent: self-lubricating high-strength cast nylon preparation method (application number: 201110009588.3, ​​publication number: 102153743A) using c...
