Embodiment 1

[0010] An industrial grease extreme pressure additive, consisting of base oil; molybdenum disulfide; chlorinated paraffin; diarylamine; ethoxylated phenols; Isobutylene; composed of polyethylene. The base oil is composed of three components of M14 and 32# of mineral oil and rapeseed oil of vegetable oil, and the weight ratio of the three components is 1:1:1. The weight percent of each component is: 32% of base oil; 28% of molybdenum disulfide; 20% of chlorinated paraffin; 3% of diarylamine; 3% of ethoxylated phenols; Dialkyldithiophosphate 5%; Polyisobutylene 4%; Polyethylene 2%. The above base oil; molybdenum disulfide; chlorinated paraffin; diarylamine; ethoxylated phenols; Parts shall be measured in percentage by weight. Mix evenly, heat and control the temperature between 60-80°C, and stir for 120 minutes to obtain the product of the present invention.

[0011] Adding this product to ordinary lubricating grease according to the dosage of 5% has the following advantages...

Abstract

The invention relates to an industrial grease extreme pressure additive which is basically characterized by comprising the following compositions in percentage by weight: 28-32 percent of molybdenum disulfide, 20-22 percent of chlorinated paraffin, 3-5 percent of diarylamine, 3-5 percent of ethoxy phenols, 3-5 percent of double salicylidene diaminopropane, 5-7 percent of dialkyl dithiophosphate, 4-6 percent of polyisobutylene, 2-3 percent of polyethylene and the balance of base oil. The invention has the advantages of simple preparation, convenience, easy application, economy and practicability, can keep good grease consistency for a long time, ensures stable extreme pressure resistance of a gear, a bearing and a mechanical part which has heavy load and is subjected to impact load, enhances comprehensive maintenance on various equipments using lubricating grease, and comprehensively promotes various performances of the grease and prolongs a use period of the grease while ensuring that the extreme pressure resistance of various mechanical equipments is improved.

Description

(1) Technical field [0001] The invention relates to a lubricating grease additive, in particular to a preparation scheme and a preparation method of an industrial lubricating grease extreme pressure additive. (two) background technology: [0002] Because the semi-solid state of the grease makes it easier to seal the grease into the bearing, the grease also acts as a seal against contamination in wet and dusty environments. Therefore, the use of lubricating grease is in great demand. With the progress of society and the development of human science, all kinds of mechanical equipment are constantly developing, so it is required to improve the working performance of various lubricants. Grease should improve various performances because of its working characteristics. In applications where shock loading occurs, such as in large excavator bearings and some conveyor belt bearings, the rapid loading of the load can cause galling of the metal before the dissolved extreme pressure a...
