Problems solved by technology

However, there are still many disadvantages in the water-based lubricating and antifriction agents currently available in the market: first, the high-temperature lubricating performance and heat resistance are poor (the high-temperature friction coefficient is generally greater than 0.1, and the thermal decomposition rate is generally greater than 40%); the second is the formula The components all contain toxic and harmful substances such as heavy metals and aromatic hydrocarbons, which affect human health and poor safety and hygiene quality

Abstract

The invention discloses a water-based type lubricating antifriction agent for an ultra-large type die-casting machine. The water-based type lubricating antifriction agent is prepared from vegetable oil, synthetic ester, inorganic powder, an antirust agent, a novel surfactant and water. The water-based type lubricating antifriction agent does not contain graphite and has excellent continuous high-temperature lubrication performance, emulsion stability and heat resistance.

Description

technical field [0001] The invention relates to a water-based lubricating and antifriction agent. Background technique [0002] Die-casting machines are widely used in industries such as automobiles and household appliances to die-cast metal products. Die-casting is characterized by high speed and high pressure. During die-casting, the plunger rod (also called punch) and the pressure chamber of the die-casting machine are in direct contact with the molten metal under high speed and high pressure, and they rub against each other at high speed. In order to reduce the wear of the cylindrical surface of the punch and prolong the service life of the punch and the pressure chamber, it is required that the lubricating and anti-friction agent used together must have excellent continuous lubricity and heat resistance. As the market demand for super-large metal parts continues to increase, the application of super-large die-casting machines is becoming more and more extensive. Ultra...
