Problems solved by technology
[0002]In the field of hydraulic oil production, due to many deficiencies in the performance and source of mineral oil base oils, non-petroleum hydraulic oils have been more widely and deeply used. At present, the most widely used fire-resistant hydraulic oil is water-glycol liquid, but it has problems such as corrosion of metals, poor lubricity, flame resistance and wear resistance, and long defoaming time in use, which limits it to a certain extent. The scope of application of fire-resistant hydraulic oil is limited, and the existing preparation process of water-based fire-resistant hydraulic oil is mostly direct heating reaction and simple filtration, resulting in low cleanliness of water-based fire-resistant hydraulic oil

Embodiment 1
[0017] The preparation process of the water-based fire-resistant hydraulic oil of the present embodiment is characterized in that the process steps are as follows:
[0018] (1) Material preparation: It is composed of the following raw materials according to mass percentage: water 40%, ethylene glycol 41.3%, thickener 10%, anti-wear agent 1%, defoamer 1‰, preservative 1‰, rust inhibitor 5 %, metal deactivator 5‰ and detergent dispersant 2%;
[0019] (2) Reaction: Add the raw materials into the reaction tank, heat up and stir for 2-3 hours, and the temperature rises to 60-80°C to obtain the initial product;
[0020] (3) Detection and filtration: Sampling the primary product in the reaction tank, testing the kinematic viscosity, anti-wear performance, defoaming time and Ph value of the sample, and after passing the test, perform three-layer filtration treatment to obtain the secondary product;
[0021] (4) Re-reaction: Add the secondary product into the large reaction tank and s...
Embodiment 2
[0025] The rest are the same as in Example 1, the difference is that the three-stage filtration in step (3) is filtered by an ordinary filter element filter tank. Although the operation is more convenient, time-saving and labor-saving, the filtering effect is not good, and the obtained finished product is clean The degree cannot reach NS6 level.
[0026] According to experiments, through the preparation process of the above-mentioned water-based fire-resistant hydraulic oil, different high-standard and high-quality water-based fire-resistant hydraulic oils can be produced according to the reasonable ratio of raw materials, and the process is reasonable and clear. It greatly improves the production efficiency, is suitable for the needs of its production process, effectively improves the quality of the enterprise's products, and the produced products have excellent flame resistance, lubricity and rust resistance, and can be widely popularized and applied.

Abstract
The invention relates to a preparation process of water-based fire resistant hydraulic oil. The process comprises the following steps: (1) preparing the following raw materials in percentage by mass: 40 percent of water, 41.3 percent of ethylene glycol, 10 percent of a thickening agent, 1 percent of an anti-wear agent, 0.1 thousandth of a deforming agent, 1 thousandth of a preservative, 5 percent of an antirust agent, 5 thousandths of a metal passivator and 2 percent of a purification dispersant; (2) reacting the raw materials; (3) testing and filtering a reaction product; (4) reacting the reaction product once again; and (5) filling a final reaction product. The preparation process is easy to operate, and is stable in mixture ratio. The produced water-based fire-resistant hydraulic oil has superior fire resistance, lubricity and anti-rust property, and has high cleanability.
