Problems solved by technology

[0004] The purpose of the present invention is to provide an anti-ultraviolet and anti-discoloration ultra-clean hydraulic oil to solve the above-mentioned background technology. Other functions require other additives to have other special functions, which limits the scope of application of the product and does not have the effect of anti-ultraviolet rays. In summer, when the ultraviolet rays are strong or it is used outdoors, it may damage the equipment. It will cause damage and affect its normal use. At the same time, under long-term use, the inside of the device may appear discolored. It is inconvenient for maintenance personnel to identify the state of its use. It needs to be disassembled before it can be identified. , which increases the difficulty of work, prolongs the time for maintenance work, reduces the speed and efficiency of work, and at the same time, the mixture of products and additives is prone to irritating odor due to the different internal components, which affects the working environment Air, problems with high turbidity

Abstract

The invention discloses anti-ultraviolet anti-discoloration ultra-clean hydraulic oil which is prepared from the following components in parts by weight: base oil, methyl silicone oil, benzotriazole, sodium tripolyphosphate, a demulsifying agent, nano silicon dioxide, a UV-531 ultraviolet light absorber, an antioxidant, an anti-wear agent, a dispersing agent, a viscosity modifier, a defoaming agent, a lubricating agent and a cosolvent. According to the anti-ultraviolet anti-discoloration ultra-clean hydraulic oil, the problems that hydraulic oil in the existing market cannot resist ultraviolet and discoloration and is high in turbidity are solved, the protection effect on equipment after the product is used is improved, the anti-ultraviolet and anti-discoloration capacity is improved, meanwhile, a lubricating medium is used for slowing down abrasion of the product, the hydraulic oil has the functions of cleaning, preventing pollution and the like, prevents sedimentation and agglomeration of particles, improves the use effect of a product, delays yellowing, blocks physical property loss, better meets the use requirements, helps to improve the working speed and can facilitate work of workers.

Description

technical field [0001] The invention relates to the technical field of hydraulic oil, in particular to an anti-ultraviolet, anti-discoloration and ultra-clean hydraulic oil. Background technique [0002] Hydraulic oil is the hydraulic medium used in the hydraulic system using liquid pressure energy. It plays the role of energy transmission, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling, etc. in the hydraulic system. For hydraulic oil, it should first meet the requirements of the hydraulic device. Requirements for liquid viscosity at working temperature and starting temperature, since the viscosity change of lubricating oil is directly related to hydraulic action, transmission efficiency and transmission accuracy, it is also required that the viscosity-temperature performance and shear stability of the oil should meet the requirements of different uses There are many types of hydraulic oils, and the classification methods are different. For a long time, it...
