Lubricating oil special for numerical control machine tool gear and preparing method thereof

Abstract

The invention relates to lubricating oil special for a numerical control machine tool gear and a preparing method thereof. The lubricating oil comprises biological base oil and an additive; the biological base oil is prepared from, by weight, 10-30 parts of peanut oil, 12-20 parts of sunflower seed oil, 7-10 parts of castor oil, 4-8 parts of peony seed soil, 2-5 parts of linseed oil soil, 2-4 parts of rice bran oil, 3-4 parts of shiny-leaved yellowhorn oil, 2-5 parts of tea oil and 1-3 parts of algal oil; the additive is prepared from, by weight, 20-50 parts of antioxidant, 6-10 parts of dispersant, 10-15 parts of foam inhibitor, 12-18 parts of viscosity improver and 8-10 parts of oiliness agent. Though the selected biological base oil is high in cost, the increased expense is sufficient to offset environmental governance expense caused by using other kinds of mineral oil and synthesizing the base oil, and by adding the additive, the lubricating oil is high in antioxidation, corrosion resistance and foaming resistance and is particularly suitable for the rotating gear of a high-precision machine tool.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a special lubricating oil for numerically controlled machine tool gears and a preparation process thereof. Background technique [0002] China is the third largest consumer of lubricating oil in the world, with an annual consumption of nearly 4 million tons and an increasing trend year by year. In China's lubricating oil market, after years of competition, the competition pattern has gradually formed. Most of my country's high-end automotive lubricating oil market is occupied by foreign well-known brands, domestic companies mainly occupy the mid-range oil product market, and most local and private enterprises rely on mid-range oil products. , The low-grade oil market can survive. Judging from the actual situation of domestic lubricating oil production enterprises, although we already have lubricating oil enterprises with international advanced level, such as the Great Wall Lubricat...

Problems solved by technology

Judging from the actual situation of domestic lubricating oil production enterprises, although we already have lubricating oil enterprises with international advanced level, such as the Great Wall Lubricating Oil Company affiliated to Sinopec, there are still some small non-specialized production enterprises in domestic lubricating oil enterprises. Large-scale enterprises, they cannot complete the production of high-end lubricating oil products by themselves, so their products are mostly concentrated in the middle and low-end range

[0003] With the development of high-precision CNC machine tools, gears, as the most commonly used transmission mechanism, also put forward higher requirements for gears. When the gears rotate for a long time, a large amount of heat will be generated during the rotation process. To lubricate and also to play a cooling role, so it is necessary to use low-viscosity lubricating oil with good lubricating properties, and at the same time need to have good anti-oxidation, anti-corrosion, anti-rust and anti-foaming properties, the existing lubricating oil Due to the lack of formula and preparation process, it is difficult to meet such requirements
