Abstract
The invention relates to polyurea grease and a preparation method thereof, which is a production technology of a mechanical lubrication product, and the polyurea grease is prepared by the following raw materials: HVI Ia 650 base oil, 150BS base oil, diphenylmethane diisocyanate MDI, tricresyl phosphate TCP, octadecanol, n-octyl amine, aniline, T202, T706 and castor oil. The range of applications covers the lubrication of fan-shaped segment roller ways, drawing and straightening machines, pendulum shear machines, conveying rollers and the like. The polyurea grease has the following significances: 1) the polyurea grease has excellent extreme pressure air anti-wear property, and spherical thickener particles can form a rolling ball layer on the contact surface, thereby effectively reducing the surface friction of metal and prolonging the life cycle of equipment; and 2) the polyurea grease has excellent anti-rust and anti-corrosion properties, and can be resistant to erosion of the friction surface of the metal caused by seawater.
Description
One, technical field: the present invention relates to a kind of production technology of power lubrication product, especially polyurea grease and preparation method.
Two, background technology: at present, mechanical used lubricating grease is varied, has satisfied the production needs to a certain extent, but along with development of science and technology, original lubricating grease can not satisfy the needs of special mechanical.
Three, summary of the invention: the purpose of this invention is to provide a kind of polyurea grease that can satisfy the demand and preparation method, satisfied the needs of producing to a certain extent, the object of the present invention is achieved like this, and it is made by following raw material:
