Preparation method of protective nano elastic insole

Abstract

The invention relates to a preparation method of a protective nano elastic insole, which comprises the following steps: putting natural rubber into an open mill for plastication, adding nitrile rubberin a certain proportion into the open mill for mixing with the natural rubber, and then adding perfume prepared from chlorhexidine hydrochloride, nano silicon dioxide, zeolite powder, tourmaline andother materials according to a certain proportion into the open mill; conducting uniform stirring, sequentially adding a plasticizer, calcium carbonate, carbon black, zinc oxide and other materials according to a formula ratio, and conducting mixing to form a rubber compound; preparing a rubber sheet on a calender, then extruding the rubber sheet into a mold through an extruder, conducting vulcanizing for 1 h at the vulcanizing temperature of 100 DEG C, and then taking out the vulcanized material, and conducting slicing through a slicing machine according to the required thickness. The insoleprepared by the preparation method has the characteristics of thorough deodorization and sterilization effects, long function duration, no side effect on a human body, safety, sanitation, easiness inmanufacturing and the like, and can be widely applied to special shoes.

Description

technical field [0001] The invention relates to a method for preparing protective nano-elastic insoles. Background technique [0002] Special types of workers, such as hardware manufacturing, forestry, exploration and rescue operations, need to work in some special environments. Therefore, new designs need to be made for special safety protective shoes of special types of work. Due to the particularity of the occupation, such as military personnel, firefighters and other personnel, the load far exceeds that of ordinary people, and some lower limb injuries often occur, mainly manifested in excessive stretching of the arch ligament, calcaneal pain, forefoot pain and other symptoms. This is due to excessive peak pressure in the forefoot and heel area, resulting in severe compression of the nerves in the foot. In response to this situation, it is necessary to improve the protective insoles. There are many types of insoles used now, such as elastic foam materials EVA, TPU, clot...
