Description
Technical field
The present invention relates to a kind of anti-pin bubble shoe-pad for march of being born a heavy burden for high intensity and preparation method thereof, belong to high-hydroscopicity
The application field of resin.
Background technology
Bearing a heavy burden on the march, generation and the vola overload of pin bubble, the size of shoes are improper, foreign matter in footwear, walk
The factor such as humidity is relevant in fault, footwear.Wherein, humidity is most important reason in vola overload and footwear.Sole sweat
Wet to cause vola epidermis softening, vola is puted forth effort and rubbed for a long time in addition, oozes out local organization liquid and forms pin bubble.From 20 generation
Record the seventies, my army just attaches great importance to the prevention and treatment work of pin bubble.The early loading prophylactico-therapeutic measures that pin steeps on the march
Mainly there are two methods：（1）The processing of pin bubble is worn out in march way；（2）Using kerosene preventing and treating pin bubble.The former punctures row after pin bubble
Pain is more violent when walking, and easily pollution causes suppuration, recovers slower.The latter's toxicity certain because kerosene has, and pin bubble is broken
When bursting, kerosene can stimulate part, cause pain.In the 1990s, my army starts to use before daily upper and lower noon march,
Smear the method preventing and treating pin bubble such as march powder, march cream, soap, and rubberized fabric in vola.The main purpose of these methods is to pass through
The friction between vola and socks is reduced, the generation for preventing pin from steeping.It it is due to the march time although this method is cheap and easy to get
Extension, these methods also can not fundamentally prevent and treat pin bubble.Since 21 century, increasing soldier will have high-hydroscopicity energy
Sanitary napkin be used as preventing and treating pin bubble new method.Sanitary napkin is attached to the surface of shoe-pad by they, because sanitary napkin has absorbing sweat appearance
The features such as amount is high, absorbing sweat speed is fast, absorption sweat is not easily runed off, the heavy burden sweat that sole occurs on the march can be fast by sanitary napkin
Speed is absorbed, and vola epidermis is difficult softening, and the effect for preventing that pin bubble from producing is played to a certain extent.But, sanitary napkin is attached to footwear
Pad surface unsightly, disfigurement is as while durability and comfortableness are also poor during march.Therefore, develop a kind of absorbing sweat capacity height, inhale
Sweat speed is fast, protecting sweat performance, good and attractive in appearance, durable shoe-pad is to prevent and treat high intensity and bear a heavy burden to march the key of pin bubble occur.
The content of the invention
The present invention relates to a kind of anti-pin bubble shoe-pad for march of being born a heavy burden for high intensity and preparation method thereof, the shoe-pad, which has, to be inhaled
Sweat capacity is high, absorbing sweat speed is fast and protects the advantages of sweat performance is good, and attractive in appearance, durable, can solve my army of long-standing problem high-strength
Pin is produced during degree heavy burden march and steeps this protrusion problem, while at civilian aspect（Such as：Training athlete, mountaineering tour）
There is certain application prospect.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of anti-pin bubble shoe-pad for march of being born a heavy burden for high intensity, including insole body, the insole body is from top to bottom successively
