Description
Technical Field
The invention relates to the technical field of safety shoes, in particular to an acid-base-resistant and high-temperature-resistant rubber sole and a preparation process of a safety shoe.
Background
Protective safety shoes are a type of footwear used to protect the wearer from the harsh operating environment and from injuries caused by accidents. Protective safety shoes are often used in the industries of mining, smelting, casting and forging, electric power, chemical industry, fire fighting, forest felling and the like. The operation scenes comprise electrolytic aluminum furnace fronts, smelting and casting furnace fronts, electrolytic aluminum plants, aluminothermic power plants, fire rescue, natural disaster rescue and the like.
In the above-mentioned scene, the operation needs to face the problems of water accumulation, uneven ground, corrosive substances such as acid and alkali, dirt, waste hot water pollution and the like. The part of the protective safety shoes worn by the operator, which plays a role in protection, is mainly the sole. At present, the height of the side wall of the sole of the protective safety shoe on the market is less than 30mm, and the side wall of the sole is short, so that the joint of the upper and the sole is easily immersed into the upper by acid-base sewage, slag, waste hot water and the like, and the glue is broken at the joint of the upper and the sole of the protective safety shoe. In the process of walking operation, acid-base sewage and waste hot water can splash to the toe cap, gradually corrode the toe cap, lead to the toe cap to crack and split glue, and then lead to the vamp to break and crack at the sole junction. In addition, the mode that adopts the side seam line between the vamp of current protection safety shoes and the sole makes vamp and bottom seam line more firm, and side seam line department can touch high temperature slay etc. at high temperature operation in-process, causes the fusing of side seam line, loses side seam line reinforcing effect. The high-temperature radiation can cause the temperature rise of the toe cap position at the gluing position of the vamp and the sole, the glue can be broken when the temperature tolerance of shoe glue is exceeded, then the toe cap position contacts the high temperature frequently to cause the leather at the toe cap position to burn, age and crack to form a broken hole, then the protective toe cap is exposed, the protective toe cap can fall out when the shoe is used again seriously, and the shoe can not be worn again when the shoe is damaged. The above factors can be superposed to seriously shorten the service life of the protective safety shoes.
In some special operation scenes, safety shoes needing to be protected have multiple functions of electric insulation, toe protection, high temperature resistance, puncture resistance, corrosion resistance, acid and alkali resistance and water resistance, and the functions need to be made of insulating non-metallic materials. The high-temperature-resistant thermal contact protection function of the protection safety shoes in the market at present needs to drill holes on the shoe protection toe cap to perform seam lines at the joint of the upper and the side edge of the sole, which can destroy the performance of the toe protection of the nonmetal material protection toe cap to greatly reduce the impact resistance and the static pressure, and can not reach the national standard, the shoes using the metal material protection toe cap do not meet the material requirement of the electric insulation performance of the 6.4.3 clause of the national GB21148-2020 foot protection safety shoes after side seam lines are performed, the shoes should not use parts or accessories of metal materials, the requirement of up-and-down through seam lines should not be adopted in the combination of the upper and the bottom, and the labor safety of a wearer is not protected.
