Problems solved by technology

[0003] At present, the existing domestic safety boots have a single performance, but the operating environment of mines is complex, the injuries are diverse, and various foot protections are required
In recent years, various types of gas explosion accidents in coal mines have occurred frequently. Through research and analysis, coal miners currently prepare cotton anti-static clothing. If anti-static boots are prepared, the problem of static sparks can be basically solved. To solve the problem of static electricity in coal mines , it is necessary to add anti-static function on the basis of safety boots; in addition, workers wear safety boots for a long time, and the sweat on the feet is difficult to dissipate. In addition, there is no sunlight inside the boots for many years, and various molds are prone to occur, leading to various types of athlete's foot , athlete’s foot, from the perspective of occupational health of work, it is necessary to increase the antibacterial and deodorizing functions of safety boots; moreover, according to the working environment of miners, it is also necessary to increase chemical corrosion resistance, oil resistance and anti-smashing functions; in addition, the existing miner safety boots Without specific, targeted, and comprehensive technical standards, the products on the market are mixed with good and bad people, and the quality is uneven. It is impossible to guarantee supervision and management, making supervision and management blank. If things go on like this, it is not conducive to technological progress in product development.

Abstract

The invention discloses a pair of miner safety boots as well as a production method and a technical standard thereof. Boot uppers and boot soles are respectively prepared by the following components in percentage by weight: 15.9 and 15.9 PVC-S-1300, 35.1 and 29.3 DOP, 22.3 and 28.3 GLOBINEX-2340-S, 6.4 and 6.2 DOA, 2.5 and 2.5 composite rare-earth stabilizer, 1.9 and 1.9 inorganic Ag-system fungicide and 15.9 and 15.9 high-polymerised PVC. The preparation method of the safety boots comprises the following steps: firstly, respectively weighting the components in percentage by weight; producingplastic particles of the boot uppers and the boot soles in a granulator; and then, respectively adding the plastic particles to an injection machine to produce the safety boots by primary injection and twice injection. The miner safety boots achieve a certain technical standard, resist chemical corrosion, oiliness, smashing and bacteria and meet the practical needs of the mine operation for the miner safety boots.
