Embodiment 1

[0013] The novel anti-wear hydraulic oil is characterized in that it is prepared from the following raw materials in parts by weight: No. 46 base oil: second-line oil reduction: benzotriazole fatty acid amine salt: isopropyl palmitate: polyisobutylene vulcanization: tertiary Butylphenol: silicone oil = 87:75:0.65:0.85:0.7:0.2:0.2.

[0014] The No. 46 base oil can be replaced by the third line oil.

[0015] The technological method of preparing described novel anti-wear hydraulic oil:

[0016] According to the formula ratio, first add the above raw materials into the refining kettle with clay, the addition amount is 3-8% of the raw material oil and stir evenly, use a vacuum system to heat up and dehydrate, control the temperature at 120-140°C, 10-20min, filter as soon as possible Clay clay, cooled to 65-90°C, then slowly add other raw materials, stir evenly, cool and filter to obtain the finished product.

Embodiment 2

[0018] The new anti-wear hydraulic oil is prepared from the following raw materials according to the ratio of parts by weight: No. 46 base oil: reduced second-line oil: benzotriazole fatty acid amine salt: isopropyl palmitate: polyisobutylene vulcanization: tert-butylphenol : silicone oil=79:81:0.08:1.2:1.2:0.3:0.4. Others are with embodiment 1.

Embodiment 3

[0020] The new anti-wear hydraulic oil is prepared from the following raw materials according to the ratio of parts by weight: No. 46 base oil: reduced second-line oil: benzotriazole fatty acid amine salt: isopropyl palmitate: polyisobutylene vulcanization: tert-butylphenol : silicone oil=95:60:0.05:0.3:0.6:0.07:0.09. Others are with embodiment 1.

Abstract

The invention relates to hydraulic oil, in particular to novel wear-resistant hydraulic oil with good adaptability. The ratio of No.46 base oil to base VGO No.2 oil to benzotriazole fatty acid amine salt to isopropyl palmitate to vulcanized polyisobutene to tert-butyl phenol to silicone oil is (79-95): (60-81): (0.05-0.08): (0.3-1.2): (0.6-1.2): (0.07-0.3): (0.09-0.4). The novel wear-resistant hydraulic oil has good viscosity-temperature performance, extreme pressure wear resistance, anti-oxidation stability, hydrolytic stability and thermal stability, so the aging and the degradation are not easy to occur, the service life is prolonged, the normal lubrication of friction pairs under the rigorous conditions of high pressure and high speed is realized, and the abrasion is reduced. The foam generated under the conditions of violent mechanical stirring in the operation process can be ensured to fast disappear, and in addition, air mixed into the oil can be released in a short time for realizing the accurate, sensitive and stable static pressure transmission.

Description

technical field [0001] The invention relates to a hydraulic oil, in particular to a novel anti-wear hydraulic oil with good adaptability. Background technique [0002] Hydraulic oil is the hydraulic medium used in the hydraulic system that utilizes liquid pressure energy. It plays the role of energy transmission, system lubrication, anti-corrosion, rust prevention, cooling, etc. in the hydraulic system. For hydraulic oil, it should first meet the requirements of the hydraulic device on the viscosity of the liquid at the working temperature and the starting temperature. Since the viscosity change of the oil is directly related to the hydraulic action, transmission efficiency and transmission accuracy, the viscosity-temperature performance of the oil and the Shear stability should meet the various needs raised by different uses. There are many kinds of hydraulic oils, and the classification methods are different. For a long time, it is customary to classify them by use, and s...
