The commonly used thickener in the market is polyether. For example, the patent (CN 102086642 A) uses 12%-15% water-soluble polyether as a thickener, and the patent (CN 10134874 A) uses 15%-25% water-soluble polyether as a thickener. Ether is used as a thickener, but in order to achieve a better thickening effect, the amount of polyether added often needs to be higher. The traditional method of adding thickener polyether has poor thickening effect, large dosage, low dissolution rate and Disadvantages such as difficulty in cleaning

Embodiment 1
[0020] Weigh the raw materials (kg) according to the following ratio:
[0024] The mass concentration of anionic polyacrylamide solution is 0.5%, the relative molecular mass of anionic polyacrylamide is 10 million, and the relative molecular mass of polyether is 50,000-100,000.
[0025] The production method is as follows:
[0026] Firstly, anionic polyacrylamide with a relative molecular mass of 10 million is prepared into a solution with a mass concentration of 0.5%, and then a solution of the required mass is taken, and polyether with a relative molecular mass of 50,000 to 100,000 is added and stirred. The solution is clear and transparent Add polyacrylic acid and ...

Abstract
The invention discloses a water-alcohol type hydraulic fluid thickener as well as a preparation method and an application of the thickener. The technical scheme has the important points that the water-alcohol type hydraulic fluid thickener mainly contains the following raw materials in parts by weight: 30-50 parts of polyether, 10-20 parts of polyacrylic acid, 10-30 parts of sodium polyacrylate, 10-30 parts of anionic polyacrylamide with the mass concentration of 0.5%. The invention also discloses the preparation method of the water-alcohol type hydraulic fluid thickener, a water-ethylene glycol hydraulic fluid prepared from the water-alcohol type hydraulic fluid thickener, and a preparation method of the water-ethylene glycol hydraulic fluid. The water-alcohol type hydraulic fluid thickener is easy to degrade, free of toxic and side effects on environment and human bodies, and safe to use, so that the thickened water-ethylene glycol hydraulic fluid is widely applied to hydraulic systems of steel-making equipment, iron-smelting equipment, hot rolling equipment, metal die-casing equipment and the like.
Description
Technical field [0001] The invention relates to the technical field of hydraulic fluid thickeners, in particular to a water-alcohol type hydraulic fluid thickener, and a preparation method and application thereof. Background technique [0002] Water-glycol hydraulic fluid is currently widely used as a transmission medium in many hydraulic equipment at home and abroad. It has excellent flame resistance, cold resistance, abrasion resistance, excellent rust resistance, foam resistance and extremely long service life. , It can meet the high standards of environmental protection requirements and other advantages. Since 1970, it has been widely used in metallurgy, mining, machinery manufacturing, casting and military processing. In recent years, with the continuous improvement of equipment oil standardization, the demand for water-glycol hydraulic fluid has also increased. [0003] The water-glycol hydraulic fluid has a water content of about 50% or higher, and the viscosity of the wate...
