Abstract

The invention discloses a foot blister resistant shoe pad for high strength load bearing march and a preparation method of the foot blister resistant shoe pad. The preparation method comprises the following steps: (1) mixing EVA, a foaming agent and a cross-linking agent, and mixing the mixture by using an internal mixer to obtain a mixed material; (2) putting the mixing material into a sheet extruder so as to be processed into required shoe pad body embryos, enabling the body embryos to be subjected to hot-pressing foaming molding, forming by cooling to obtain an EVA foaming material of the required shoe pad ventilation sweat permeating layer; (3) cutting micro-polypropylene fiber fabric into a shoe pad shape, then utilizing EVA glue to sticking the micro-polypropylene fiber fabric on the ventilation sweat permeating layer, perforating a stuck fabric layer and a ventilation sweat permeating layer by using a perforating machine so as to enable the ventilation sweat permeating layer to be filled with fine holes uniformly; and (4) filling compression resistant salt tolerant super absorbent resin in a buffering water absorbing layer blind hole, sticking the ventilation sweat permeating layer and a buffering water absorbing layer by using the EVA glue to obtain the foot blister resistant shoe pad. The foot blister resistant shoe pad can be used for solving the problem that foot blisters are generated in the process of high strength load bearing march.

Description

technical field [0001] The invention relates to a foot-bubble-proof insole for high-strength load-bearing marches and a preparation method thereof, belonging to the application field of superabsorbent resins. Background technique [0002] During the weight-bearing march, the occurrence of foot blisters is related to factors such as excessive load on the soles of the feet, improper size of shoes, foreign objects in shoes, incorrect walking posture, and moisture in shoes. Among them, the soles of the feet are overloaded and the moisture in the shoes is the most important reason. Sweaty soles cause the skin on the soles of the feet to soften, coupled with long-term force and friction on the soles of the feet, causing local tissue fluid to ooze out and form foot blisters. Since the 1970s, our army has attached great importance to the prevention and treatment of foot blisters. There are two main methods for the prevention and treatment of foot blisters during the early load-bea...
