Description
Technical field
The present invention relates to sorbing material technical field, specifically a kind of sorbing material for insole deodorization.
Background technology
It is foul smell with the improvement of living standards, people constantly pursue the living environment of comfortable health, and in air, different
Taste, it is not only unpleasant, also harmful to health.So in daily life, people are also continuous to the needs of deodorant
Increase, various deodorant also come into being.The most frequently used deodorant is physical absorption principle, and main sorbing material is to live
Property charcoal, carbon fiber, all kinds of zeolites, certain metal oxides and large pore macromolecular material etc..It is removed currently, the country is also in common use
Smelly dose mainly has：A few major class products such as natural plant liquid deodorant, biological deodorant, fragrant and deodorizing agent, macromolecular deodorizer.Its
In, natural plant liquid deodorant, fragrant and deodorizing agent belong to spreadability deodorant, are specifically exactly no elimination stink, but
Fragrance is added in stink to neutralize stink, is allowed to reduce the influence of stink from sense organ.Other deodorant currently on the market
There are specific surface areas it is small, adsorbance is low, regeneration is difficult, of high cost, odor removal efficient is low, deodorizing effect is poor the deficiencies of.
Shoes are the object of people's indispensability, but foot odour, shoes caused by pin sweat, tinea pedis are smelly, socks are smelly annoyings always.In order to solve
This problem, people have correspondingly invented the articles for use such as stink prevention hosiery, deodorizing shoe-pad, but all to there is the deodorization time short, anti-for this kind of article
The problems such as smelly effect is poor.The present invention puts deodorization adsorbent by simple operations in shoes can effectively remove the peculiar smell of footwear.
Invention content
The present invention for existing footwear deodorization there are the problem of, a kind of sorbing material for footwear deodorization, the suction are provided
Enclosure material has many advantages, such as large specific surface area, large amount of adsorption, can efficient absorption stink, cost is relatively low, preparation process is simple.
In order to achieve the goal above, the technical solution adopted by the present invention is as follows：
A kind of sorbing material for footwear deodorization includes the raw material composition of following parts by weight：50-100 parts of modified activated carbon,
30-50 parts of modified coal ash, 3-8 parts of crosslinking agent, 5-10 parts of chitosan and total with dimethyl diallyl ammonium chloride-acrylamide
4-8 parts of polymers.
Further, the activated carbon is that coffee grounds is prepared through peroxophosphoric acid and the modification of coconut oleoyl amine alkanol sodium sulphate
It arrives.
Further, the preparation method of the activated carbon is：Coffee grounds is crushed to 100-300 mesh, is soaked with phosphoric acid solution
2-12h is steeped, is dried after cleaning, is roasted 2-3h at 300-500 DEG C, obtain activated carbon；Coconut oleoyl amine alkanol sodium sulphate is dissolved in water
It is made into the solution of a concentration of 5-10%, activated carbon is added in coconut oleoyl amine alkanol metabisulfite solution, stirs evenly, is dried, you can
Obtain modified activated carbon.
Further, the mass concentration of the phosphoric acid solution is 10-15%.
Further, the addition of the coconut oleoyl amine alkanol sodium sulphate is the 3-5% of coffee grounds quality.
Further, the modified coal ash is that sodium hydroxide solution is added in flyash to impregnate 1-3h, is washed with water
After dry；Poly- aminopropyltriethoxy silsesquioxane is dissolved in the solution that water is made into concentration 10-20%, poly- ammonia is added in flyash
Hydroxypropyl methyl silsesquioxane solution, stirring 20-30min is to get to modified coal ash.
Further, the addition of the poly- aminopropyltriethoxy silsesquioxane is the 4-6% of flyash quality.
Further, the crosslinking agent is N hydroxymethyl acrylamide, the double isopropyl titanate esters of double triethanolamines, three hydroxyl first
One or more combinations in base propane three (3- aziridinyls propionic ester).
The preparation method of sorbing material of the present invention for footwear deodorization, includes the following steps：
（1）Crosslinking agent, chitosan and dimethyl diallyl ammonium chloride-acrylamide copolymer are dissolved in 100-200 parts of water, obtained
Mixed liquor；
（2）50-100 parts of modified activated carbon, 30-50 parts of modified coal ash are added in mixed liquor, stirs 30-60min, it is dry,
The particle of 1-2mm grain sizes is made, packs, obtains the sorbing material for footwear deodorization.
The deodorizing method of sorbing material of the present invention is：Packaged sorbing material is placed in shoes can deodorization.
Compared with prior art, it advantages of the present invention and has the beneficial effect that：
1, sorbing material provided by the invention is smelly to shoes has good suction-operated, can fast and effectively remove shoes stink,
Easy to operate, highly reliable, cost is more cheap, preferably removes the peculiar smell that shoes are smelly, socks are smelly, has good social benefit, life
State benefit and economic benefit.
2, the present invention comprehensively utilizes waste, reduces the cost system of sorbing material using coffee grounds as the material of activated carbon
Standby activated carbon has many advantages, such as that large specific surface area, adsorption effect are good, and activated carbon phosphoric acid and coconut oleoyl amine alkanol sodium sulphate change
Property, aperture and the specific surface area of activated carbon can be increased, absorption property significantly improves, and improves the ability of absorption shoes stink.
3, the flyash that the present invention uses first uses aminopropyltriethoxy silsesquioxane to be modified again with soaking with sodium hydroxide, improves
The activity of flyash and aperture, improve the specific surface area and deodorizing capability of flyash, waste resource are made to have obtained sufficient profit
With, and reduce the cost of adsorbent.
4, be additionally added in raw material of the invention crosslinking agent, chitosan and with dimethyl diallyl ammonium chloride-acrylamide
Copolymer makes deodorant have superior adhesive force, and adsorption capacity is big, and the rate of adsorption is fast, notable to the absorption property of peculiar smell
It improves.
