Description

Technical Field

[0001] The invention relates to the technical field of antifreeze agents, and in particular to an antifreeze agent for automobile transportation of bulk ore and a preparation method thereof. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in an ore is called ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are often expressed in percentages. Ore grade is often used to measure the value of an ore, but the composition of the gangue (useless minerals in the ore or minerals with very little useful components and cannot be utilized) and the amount of harmful impurities in the ore also affect the value of the ore.

[0003] At present, during the transportation of ore in cold weather, antifreeze is usually sprayed on the ore to prevent the ore from freezing. However, the anti-corrosion performance of the existing antifreeze is limited, which will affect the use environment of the antifreeze. Therefore, an antifreeze for automobile transportation of bulk ore and a preparation method are invented. Summary of the invention
