Low-VOC anti-rust oil used for thermal treatment of precise thin-wall bearing of robot

Abstract

The invention discloses a low-VOC anti-rust oil used for thermal treatment of a precise thin-wall bearing of a robot. The anti-rust oil is prepared from Yubase 4 Plus, 5# white oil, palm oil, Span 80,Span 85, Tween 80, an ethylene a-olefin copolymer, C12-15 alkanol polyether-2, an isomerous C13 alcohol ethyoxyl compound, diethylene glycol monobutyl ether, 3-methoxy-3-methyl-1-butanol, Irganox L 57 and Irganox L64. The anti-rust oil is low in VOC content, excellent in thermal decomposition performance and good in anti-rust performance.

Description

technical field [0001] The invention relates to an antirust oil for heat treatment of thin-walled bearings. Background technique [0002] As one of the key supporting components of industrial robots, industrial robot bearings directly affect the performance, quality and reliability of major equipment and host products, and are known as the "heart" components of equipment manufacturing. The precision, friction torque and rigidity of the supporting bearings directly affect the stability and safe operation of the entire harmonic reducer and even the robot. Industrial robot bearings mainly include equal-section thin-walled bearings, thin-walled crossed cylindrical roller bearings, harmonic reducer bearings, linear bearings, joint bearings, etc., but the first two types of thin-walled bearings are the most used. The development of modern industrial robots tends to be lightweight. Bearings must be installed in a limited space. They must be small in size and light in weight. Only...

Problems solved by technology

At present, the common anti-rust oils on the market are all solvent-diluted anti-rust oils. The products contain a large amount of volatile kerosene and solvent oil that are poisonous to the human body. The VOC (volatile organic compound) content exceeds the standard, which seriously affects the working environment and human health.

In addition, the current commercially available antirust oils for bearing heat treatment all contain metal salt rust inhibitors such as barium petroleum sulfonate and calcium petroleum sulfonate. If the amount is too high, the reflectivity is usually <50%, which will cause the surface of the bearing to become black after heat treatment and seriously affect the product quality
