Description

Aerogel shoe-pad

Technical Field

The utility model relates to a protection shoes field, concretely relates to aerogel shoe-pad.

Background

The insole is a shoe lining which is made into a sole shape and is attached in the shoe. The foot is the most concentrated part of the human body, and has about 25 ten thousand sweat glands. In the daily walking process of most people, particularly after a large amount of sports, the sweat secretion amount is increased sharply, in a relatively closed environment in shoes, the relative humidity is close to 100%, the temperature reaches 35-40 ℃, and the high-humidity, high-temperature and high-nutrient environment in the shoe cavity causes the high-speed propagation of bacteria, so that the stink in the shoe cavity and the foot diseases such as dermatophytosis, tinea pedis and the like are caused. Sweat contains water, salt, lactic acid and urea. Because the sweat gland of the sole heart is abundant and easy to sweat, under the condition of hyperhidrosis, bacteria on the foot multiply and decompose cutin, and urea and lactic acid in sweat are added, so that odor can be generated. If the shoes are not breathable and the air is not circulated, the odor is more concentrated. The insole is a daily article which can not be detached every day along with the soles of people, and the health of people is influenced directly by the quality of the insole.

The traditional mode of realizing the heat preservation performance of the insole products mainly can be divided into two ways of heating and heat preservation. The electric heating insole is required to introduce large-area solid elements such as a battery, a heating wire, a heating film, a temperature control wire and the like, so that the hardness and the weight of the insole are greatly increased, the practicability and the convenience of the product in the use process are low, and some problems also exist in the safety. Most of the traditional warm-keeping insoles adopt different warm-keeping materials, and the material structure keeps as much as possible of still air so as to achieve the effect of heat insulation. Such an approach often sacrifices other properties of the insole to achieve better warmth, such as too thick an insole, too poor air permeability, too soft and inelastic material, etc. Some products adopt metal materials with far infrared reflection function to realize the temperature locking effect, but because the area of the insole is very small, the heat preservation performance of the product in practical application is very limited.

In the prior art, the aerogel has low density and good heat insulation effect, is applied to upper lining materials and soles of shoe bodies, realizes the heat insulation effect of shoe cavities, and is helpful for lightening shoes. Because aerogel gas tightness is good and a hydrophobic material, so can make human foot in the sweat of sealing that shoes chamber produced, the experience of wearing is poor, moreover in the use because under the effect of foot sweat, moist, can produce foul smell, beriberi. More importantly, the gel has a certain expansion rate after absorbing moisture, and if the gel material is directly used as the interlayer of the insole, the insole is easy to distort and deform due to overhigh expansion rate.
