Problems solved by technology

In the process of coal mining, it is necessary to spray water on the mining surface to reduce dust, so that the mined coal contains a certain amount of water. During the transportation of coal in winter, the coal is very easy to freeze with the wagon. This has caused great difficulties, affecting the efficiency of vehicle turnover and coal transportation, and on the other hand, it also directly affects the economic benefits of cargo owners and railway departments.
[0004] At home and abroad, many different methods have been tried to solve the problem of coal freezing, such as electric heating, magnetic pulse vibration, and smearing paraffin or diesel on the surface of the car body. The service life of the carriage and the quality of the coal cannot fundamentally solve the problem

Embodiment 1

[0016] 1) Preparation of raw material oil: Weigh 30kg of lard and 0.3kg of stearic acid, mix and heat to 100°C under stirring, after all are dissolved, add 15kg of washing oil as mesophase oil under heat preservation, and stir for 30min after, standby;

[0017] 2) Weigh 0.5kg of industrial grade sodium hydroxide, 0.6kg of monoglyceride stearate and 53.6kg of water under stirring, and heat to 60°C. The raw material oil is slowly added in the state of stirring, and after stirring for 30 minutes, the heating is stopped, and the finished product is obtained after cooling to room temperature. This product can be used in the environment of -20—-40°C.

Abstract

The invention relates to an isolating anti-freezing liquid for a freight train body. The isolating anti-freezing liquid comprises components in percentage by mass as follows: 35%-55% of water, 0.1%-0.3% of an emulsifier I, 0.2%-0.6% of an emulsifier II, 5%-15% of intermediate phase oil, 30%-60% of raw oil and 0.1%-0.5% of sodium hydroxide. A preparation method of the isolating anti-freezing liquid for the freight train body comprises following preparation steps: preparation and synthesis of the raw oil. According to the technical scheme, the problem that the inner wall of a coal train carriage and coal are frozen together in a cold region in winter can be effectively solved on the basis that the anti-freezing liquid still has the fluidity and the cured film forming characteristic under the condition of low temperature, and the anti-freezing liquid has the characteristics of low investment, low cost, convenience in use and the like and can be used in the environment at the temperature of subzero 20-subzero 40 DEG C.

Description

[0001] Technical field [0002] The invention relates to an antifreeze liquid, in particular to an antifreeze liquid for isolation of freight train body. Background technique [0003] Railway is the main channel for coal transportation in my country. According to statistics, the transportation volume of water-containing coal by railway is close to more than 70% of the total transportation volume. In the process of coal mining, it is necessary to spray water on the mining surface to reduce dust, so that the mined coal contains a certain amount of water. During the transportation of coal in winter, the coal is very easy to freeze with the wagon. This has caused great difficulties, which has affected the efficiency of vehicle turnover and coal transportation, and on the other hand has directly affected the economic benefits of cargo owners and railway departments. [0004] At home and abroad, many different methods have been tried to solve the problem of coal freezing, such as e...
