Embodiment 1-5

[0040]Embodiment 1 is taken as an example below for description.

Embodiment 1

[0042] Anti-wear hydraulic oil in embodiment 1 is prepared according to the following steps:

[0043] (1) Mix polyethylene glycol and alkaline clay evenly, heat at 80° C. for 2 hours, pulverize after cooling, and obtain mixture 1 after passing through a 200-mesh sieve;

[0044] (2) Put the mixture 1, the antioxidant and the preservative into the degradable base oil and stir evenly to obtain the anti-wear hydraulic oil. Among them, the degradable base oil is made of vegetable oil and mineral oil according to the weight ratio of 1:1.1, the vegetable oil is soybean oil, the content of phospholipid in soybean oil is 1.2%, the mineral oil is 500N base oil; the preservative is 2.2- Dibromo-3-cyanoacetamide, anti-oxidant is selected from erythorbic acid.

[0045] As shown in Table 1, the difference between Examples 1-5 mainly lies in the different ratios of raw materials

[0046] Table 1

[0047]

Embodiment 6

[0049] The difference between this embodiment and embodiment 3 is that the weight ratio of vegetable oil to mineral oil in the degradable base oil is 1:1.2. As shown in Table 2, the difference between Example 3 and Examples 6-9 mainly lies in the weight ratio of vegetable oil to mineral oil in the degradable base oil.

Abstract

The invention relates to the technical field of hydraulic oil, and particularly discloses anti-wear hydraulic oil and a production process thereof. The formula of the anti-wear hydraulic oil comprises the following raw materials in parts by weight: 90-110 parts of degradable base oil, 1-2 parts of a preservative, 1-2 parts of an antioxidant, 2-4 parts of polyethylene glycol and 2-4 parts of alkaline carclazyte, wherein the degradable base oil is prepared by compounding vegetable oil and mineral oil. The polyethylene glycol and the alkaline carclazyte have a synergistic effect, so that the possibility of degradation of the anti-wear hydraulic oil in the use process is reduced, and the service life of the anti-wear hydraulic oil is prolonged.

Description

technical field [0001] The application relates to the technical field of hydraulic oil, more specifically, it relates to an anti-wear hydraulic oil and its production process. Background technique [0002] Hydraulic oil is the hydraulic medium used in hydraulic systems that utilize liquid pressure energy. Traditional hydraulic oil is compounded from mineral oil. Mineral oil is difficult to degrade in nature, and it is easy to cause environmental pollution. In order to meet the requirements of environmental protection, the call for the development of degradable hydraulic oil has become more and more loud in recent years. [0003] The Chinese patent with the notification number CN104845711B discloses an environmentally friendly anti-wear hydraulic oil, which includes components A, B and C, and component A includes components A and B, and its components include the following components: Component A: Component A : linseed oil, castor oil, sunflower oil; B component: sorbitan mo...
