Abstract

The invention discloses an environment-friend lubricating grease and making method, which comprises the following parts: 15-95% basic oil, 5-85% thickener, 0. 01-5% additive. The making method comprises the following steps: 1. blending the basic oil and thickener; stirring; heating until the thickener is dissolved in the basic oil; insulating 0-8h; 2. heating the composition; stirring; insulating 0-5min; 3. cooling the composition; adding the additive; grinding or cutting. The invention improves the awl-in degree, dripping point, oxidizing stability and environment friendness, which simplifies the technique.

Description

technical field [0001] The invention relates to a lubricating grease and a preparation method thereof. Background technique: [0002] In many occasions where grease is applied, such as heavy construction and mining equipment, steering wheels, rails and axles, agricultural machinery, etc., grease shedding may occur, which will eventually pollute soil, water and air, and destroy the ecological environment and ecological balance. According to reports, the German and Swiss governments have ordered to prohibit the use of mineral lubricants for boats using boats or boats above 7kw. In order to prevent lubricants from polluting Bodeness Lake, this is also the first proposal to use biodegradable lubricants. At present, in Europe, especially in Northern Europe, Germany, Switzerland and Austria, environmental friendly lubricants are highly valued, and environmental protection laws have been enacted to limit the use of mineral oil. European environmental law mandates that by the year ...
