Description
Technical field
The present invention relates to consumer goods industries, in particular to a kind of health insoles with activated carbon from bamboo.
Background technology
Shoe-pad is indispensable a kind of daily necessities in everyone daily life.Occur number of types of at present on the market
Shoe-pad contains activated carbon composition although having in part shoe-pad, but this traditional activated carbon is not excessive due to its pore radius
It is exactly too small, to the adsorption capacity of foreign matter difference it is impossible to removing peculiar smell, causing bacteria breed, residual, thus causing user foot
Sense of discomfort.
Content of the invention
It is an object of the invention to provide a kind of health insoles with activated carbon from bamboo, this health insoles have suction
Sweat, deodorant function, and the deodorizing layer of this shoe-pad is less than micro- lifes such as fine particle and the bacterium of 100nm to particle diameter in shoes
Thing has fabulous removal ability, can effectively improve the cleanliness factor of air in shoes, prevent bacteria breed, so that user foot is done
Refreshing comfortable.
In order to realize the above-mentioned purpose of the present invention, spy employs the following technical solutions:
A kind of health insoles with activated carbon from bamboo, this health insoles includes rebasing, the guarantor setting gradually from bottom to top
Strong layer, deodorizing layer and pad face, heath care layer is made of addition Chinese medical extract in yarn fabric, and deodorizing layer is in super absorbent resin
Middle addition activated carbon from bamboo is made；
Activated carbon from bamboo is prepared from accordance with the following methods:
Bamboo scraps are mixed with phosphoric acid solution and carry out to mediate 10-30min, wherein, bamboo scraps with the impregnating ratio of phosphoric acid solution are
1:1.4-1.6；The granularity of bamboo scraps is 6-35 mesh, and the water content of bamboo scraps is 12-20%；The concentration of phosphoric acid solution is 50-
55%；
The flue gas of the material after mediating and 400-650 DEG C is carried out adverse current directly contact 3.5-4.5h, so that material charcoal
Activated material is obtained, activated material, after washing, being dried and pulverize, obtains final product activated carbon from bamboo after changing and activating.
Air quality runs down in recent years, and in the air is suspended with substantial amounts of fine particle, wherein contains a substantial amounts of huge sum of money
The harmful substances such as genus, microorganism.The diameter of this fine particle of the overwhelming majority is less than 100nm, and this fine particle has very strong
Penetration capacity, vamp can be penetrated and contact with foot.And carry activated carbon although having in part shoe-pad at present, but this
The hole of activated carbon mostly is macropore (with diameter greater than 100nm) or micropore (diameter is less than 4nm), and this activated carbon exists for particle diameter
The adsorption capacity of the microorganism such as the fine particle of 4-100nm and bacterium is poor.And current, hole is transitional pore (a diameter of 4-
The production method of activated carbon 100nm) only has two kinds, and a kind of is the activated carbon to be produced for raw material with coal, another kind be by
Activated carbon after use carries out activating and regenerating.The activated carbon that both approaches produce is although hole is how based on transitional pore, but lives
Property charcoal be contained within the numerous heavy metal of content so as to purposes is limited only in the industry such as sewage disposal, and cannot be used for shoe-pad etc.
Consumer goods industries.

Experimental example
The performance characterization of the activated carbon from bamboo being prepared using the method that the present invention provides:
Due to current, hole is that the production method of the activated carbon of transitional pore a diameter of (4-100nm) only has two kinds, a kind of
It is the activated carbon to be produced for raw material with coal, another kind is that the activated carbon after using is carried out activating and regenerating.Both approaches
The activated carbon producing is although hole is how based on transitional pore, but activated carbon is contained within substantial amounts of heavy metal it is impossible to lead for food
Domain.And the activated carbon sold on the market at present, how based on wood activated charcoal and active fruit shell carbon, therefore, in the present embodiment
Compareed using commercially available wood activated charcoal and commercially available active fruit shell carbon, the performance of the activated carbon from bamboo in the present invention is entered
Row characterizes.
Sample comes from the activated carbon from bamboo producing according to the method for embodiment, and commercially available wood activated charcoal and shell
Activated carbon is as reference substance.
According to method specified in gb/t 12496-1999, the traditional performance of above-mentioned sample is measured,
According to method specified in gb/t13803.1-1999, the intensity of above-mentioned sample is measured.
Using the full-automatic specific surface area of asa p2020 type and pore size distribution determining instrument, do adsorbate with liquid nitrogen, carry out static state
The mensure of liquid nitrogen absorption method.
As shown in table 1, in other embodiments, the characterization result of activated carbon from bamboo is similar to Example 1 for the result of embodiment 1.
The performance test results of table 1. activated carbon from bamboo
As known from Table 1:
Because wood activated charcoal and active fruit shell carbon comprise only a small amount of transitional pore, so institute in the health insoles of the present invention
The performance of activated carbon from bamboo is substantially better than commercially available wood activated charcoal and active fruit shell carbon.
By contrasting to the pore diameter of each sample in table 1, it can be found that the method being provided using the present invention is made
Ratio in the range of 4-100nm for the pore diameter of standby chemical carbon is many, illustrates that its hole mostly is transitional pore.Meanwhile, also contain
A small amount of micropore, its diameter is less than 4nm.And the quantity of macropore is then relatively few a lot.As can be seen here, contain in deodorizing layer in this shoe-pad
Some activated carbon from bamboo, containing abundant transitional pore and a small amount of aperture, specific surface area is big, and diameter is less than with thin of 100nm
The grain microorganism such as thing and bacterium has good suction-operated.This activated carbon from bamboo is added in shoe-pad, can effectively go
Except in shoes, particle diameter is less than the microorganisms such as fine particle and the bacterium of 100nm, thus improving the cleanliness factor of air in shoes, prevent
Only bacteria breed, makes the foot dry of user comfortable.
Additionally, the iodine sorption value of wood activated charcoal that provides of the present invention and methylene blue adsorption value are substantially high commercially available wooden
Activated carbon and active fruit shell carbon, and the intensity of this activated carbon from bamboo is better than wood activated charcoal, is slightly weaker than active fruit shell carbon.Explanation
The absorption property of the activated carbon from bamboo prepared by method being provided using the present invention is good, intensity is larger, quality is high.
Although illustrate and describing the present invention with specific embodiment, but it will be appreciated that without departing substantially from the present invention's
Many other changes can be made in the case of spirit and scope and change.It is, therefore, intended that in the following claims
Including all such changes and modifications belonging in the scope of the invention.
