AI Technical Summary

Problems solved by technology

At present, most of the high-temperature and high-humidity operating environments in coal mines have adopted mechanical cooling. Due to the continuity of underground heat sources, the all-round three-dimensional cooling mode cannot be fully realized.
Although the cold storage capacity of the existing cold storage agents on the market meets the requirements, the temperature is relatively low (below -20°C), which is not suitable for mining cooling clothing.

Abstract

The invention discloses a cold storage agent for mining cooling clothes. The cold storage agent comprises the following raw materials: xanthan gum, sodium alginate, tween-80, ethylene glycol and water. The mass ratio of ethylene glycol to water is (1: 6)-(1: 12), the mass ratio of xanthan gum to water is (1: 20)-(1: 50), the mass ratio of sodium alginate to water is (1: 20)-(1: 50), and the mass ratio of tween-80 to water is (1: 16)-(1: 40) according to the mass ratio of each raw material to water. The invention also provides a preparation method of the cold storage agent for the mining cooling clothes. The prepared cold storage agent for the mining cooling clothes has good freezing resistance, cold insulation performance and latent heat characteristics, and can be recycled after heat exchange with a human body.

Description

technical field [0001] The invention belongs to the technical field of cold storage agents, and in particular relates to a cold storage agent for mine cooling clothes and a preparation method thereof. Background technique [0002] With the increase of coal mining depth and the improvement of mechanization, the high temperature and high humidity of the mining face become more and more serious. Occupational hygiene research and a large number of survey data show that miners work in a high-temperature and high-humidity underground environment. When the ambient temperature exceeds 28°C, the incidence of miners (low fever, dizziness, high blood pressure, stomach problems, and skin diseases, etc.) is obvious. Rise; more than 30 ℃, began to appear heat stroke accidents. At present, for the high-temperature and high-humidity operating environment in coal mines, most of them adopt mechanical cooling. Due to the continuity of underground heat sources, the all-round three-dimensional ...
