Description
Technical Field
The utility model relates to an absorb articles for use technical field, especially relate to an absorption core and absorption articles for use that are provided with small-size particle diameter porous adsorption granule.
Background
Absorbent articles such as diapers, disposable diapers, pull-ups, sanitary napkins, nursing pads, panty liners, maternal towels and the like. The function of the absorbent article is to contain the discharged materials and to isolate these materials from the body of the wearer and from the clothing and bedding. Absorbent articles, such as diapers and sanitary napkins, typically consist of a liquid pervious topsheet, a liquid impervious backsheet and an absorbent core disposed between the liquid pervious topsheet and the liquid impervious backsheet to absorb and contain liquid. Body fluids, such as urine, are collected and stored in absorbent products and are prone to produce odors. It is important for the wearer that these odors do not diffuse into the environment. The wearer needs to feel safety when using leakage and odour preventing or controlling absorbent products. The use of odour prevention in combination with absorbent products such as incontinence products is therefore an important comfort factor for the consumer.
In the field of absorbent products, several different approaches are used to prevent odours. For example, perfumes or deodorizing compounds may be used to mask odors. Odors can also be adsorbed or absorbed with particles having a large surface area, such as activated carbon, zeolites, and starch-based particulate materials. Acidic and/or alkaline odors may be neutralized by the use of materials such as baking soda and/or citric acid. For inhibition of bacteria, substances with low pH values or metal salts may be used. Accordingly, different odour control agents can be used to prevent odours in different ways.
Particulate odour control agents such as activated carbon, zeolites and starch based materials have proven to have excellent odour absorption characteristics due to the large surface area of their particles. The prior art discloses a number of absorbent articles provided with odour control agents in particulate form, all based on odour absorbing materials such as activated carbon, zeolites, silica, diatomaceous earth and the like. For example, CN1352574A discloses a superabsorbent-containing composite material composed of a particulate odor control agent such as precipitated silica, fumed silica, silicon dioxide, zeolite, clay, perlite, etc., and a fluidized bed coating material. CN1314188A discloses an absorbent article with deodorizing function, which comprises zeolite, silica gel, activated carbon, diatomite, water-soluble antibacterial compound, and cyclodextrin.

CN1241926A discloses an extensible and or flexible disposable core absorbent article comprising odour control agents such as zeolites, absorbent gelling materials, activated carbon, silica, etc. which is attached to the skin of the wearer by means of an adhesive. CN1225570A discloses a breathable absorbent article having an odour control system based on silica. CN1225571A discloses an absorbent article with an odour control system of silica, zeolite, activated carbon, absorbent gelling material and with a chelating agent.
The pore diameter of the granular porous gas absorbing material is 10-100nm, and the diameter of common peculiar smell molecules is about 0.5-1nm, such as ammonia after urine decomposition. The theory of the granular microporous material with large pore diameter is that the material can not adsorb peculiar smell molecules such as ammonia and the like. CN105393923A discloses a pet diaper, the inner pad of which is made of ramie, jute, bamboo fiber, kapok, coconut fiber, abaca, sodium alginate, ammonium acrylate-acrylate copolymer cross-linked substance, sodium bicarbonate, nano mineral crystal and photocatalyst, the patent puts the sodium alginate, the ammonium acrylate-acrylate copolymer cross-linked substance, the sodium bicarbonate, the nano mineral crystal and the photocatalyst into a reaction kettle to stir and heat to prepare deodorant odor control water-locking particles with 0.5-0.6cm of large-particle size particles, the deodorant odor control water-locking particles with the particle size are troublesome to prepare and too coarse, and the particles are easy to have strong granular feeling when contacting with skin, and are not suitable for infants and adults.
The nano mineral crystal is prepared by deep purification and scientific compatibility of natural nano mineral materials such as sepiolite, attapulgite, diatomite, bentonite, zeolite and the like through unique process technology, is pure natural and pollution-free, has good air purification effect, and can effectively remove toxic and harmful gases such as formaldehyde, ammonia, benzene series, TVOC and the like. The nano-mineral crystal has a large number of pores, the structure of the nano-mineral crystal is close to that of a 3A, 4A and 5A molecular sieve, and the pore diameter of each micropore is about 0.3-0.9 nanometer, so that three characteristics of the nano-mineral crystal are formed, and the super-strong adsorption capacity of the nano-mineral crystal is determined: only nano-scale gas molecules are adsorbed; the surfaces of the lattice pores have polarity, and the polar gas compounds are actively and preferentially adsorbed.
Therefore, compared with granular odor control materials such as active carbon, zeolite, diatomite and the like, the nano-mineral crystal particles have more efficient odor control performance on ammonia gas and the like generated after body fluid decomposition, and are pure natural substances, free of peculiar smell, clean, free of dust, non-toxic and tasteless. Meanwhile, negative ion powder can be added in the synthesis of the nano-mineral crystal, so that the nano-mineral crystal has nano-mineral crystal particles with the function of releasing negative ions.
The utility model discloses to the problem that the graininess odor control agent that discloses at present or be applied to the absorption articles for use is poor to peculiar smell molecule adsorption effects such as ammonia or the too big problem of the crystallized deodorization odor control lock water granule of industrialization's nanometer.
