Problems solved by technology

Antifreeze for hydraulic supports can meet the requirements of low freezing point, but the antifreeze for hydraulic supports in the prior art is different from emulsified oil or concentrated liquid for hydraulic supports, antifreeze is used directly without dilution, so for the user It is said that while the use is easier, the cost will increase; the existing antifreeze is basically made of high-temperature saponification, using a variety of raw materials for reconciliation, the production time is long, the production process is unsafe, there are pollution problems, and the production efficiency is low. not tall

Abstract

The invention provides a high-performance environmentally-friendly antifreeze solution for hydraulic supports. A preparation method of the antifreeze solution comprises the following steps: stirring and reacting glycerol, castor oil polyoxyethylene ether, boric acid, potassium hydroxide and water at 60 DEG C to generate an extreme pressure lubricant; and mixing ethylene glycol used as a main anticoagulant, sodium nitrite used as an antirust agent, the extreme pressure lubricant, sodium nitrite and water according to a certain ratio, and performing stirring and blending at 35-40 DEG C until thesystem is uniform and transparent in order to obtain the stable-performance antifreeze solution for hydraulic supports. The antifreeze solution has the advantages of low antifreeze point, stable usestate, good lubrication, rust prevention, extreme pressure and compatibility properties, and simplicity in production; the preparation method has the advantages of shortening of the production periodby half, avoiding of long-time high-temperature saponification reaction process in the production process, reduction of the material cost, safety and environmental protection; and insoluble substancesare not mixed into the product, so that the product quality is high.

Description

technical field [0001] The invention belongs to the technical field of coal mining, and in particular relates to a high-performance, environment-friendly antifreeze for hydraulic supports and a preparation method. Background technique [0002] Hydraulic support is one of the key equipment in fully mechanized mining face, and it is the most important underground roof support equipment, which is used to prevent roof collapse in goaf. The support, elevation, forward movement, backward slide and overload protection of the hydraulic support all rely on pressure liquid - high water content hydraulic fluid. Under normal circumstances, high-water-containing hydraulic fluid is the power transmission medium after the emulsified oil or concentrated liquid passes through the liquid. Due to the different use environments in coal mines, it is difficult to grasp the concentration during the liquid preparation process, and because the manufacturer’s formula system is different. , The refra...
