Suck appropriate negative ion every day, of great advantage to health: to make people full of vitality, Ginseng Extract and burnout, increase work efficiency; Improving water flood, eliminates neurasthenia; Reduce disease incidence, preventing cold and respiratory tract disease; Improve the symptom of Cardial or cerebral vascular diseases; Prevention air conditioning disease.To get along our mattress of having a rest and pillow of time the longest company with us, therefore, exploitation has the first-selection that the mattress of anion releasing and pillow are research workers.
Those skilled in the art has done a large amount of effort, as:
In order to provide a kind of simple and practical, safety and environmental protection, long service life, the negative ion health mattress of and health care useful to people.Application number is 201220126223.9, and patent name is that the Chinese patent of " a kind of negative ion health mattress " discloses a kind of negative ion health mattress: described negative ion band is provided with mineral substance anionic particle.Mineral substance negative ion health mattress uses supersonic machine producing the mineral substance such as mineral substance negative ion powder, then packs with medical adhesive-bonded fabric and form, and with cotton cloth, mineral substance bag is combined into cloth pad.Make spring net and balance net, the cloth pad that can produce mineral substance negative ion is placed on above spring net, by heat and the friction generation negative ion of human body, finally uses fabric cloth packaging, and with slide fastener convenient " negative ion mineral " displacement, extend its work-ing life.
Producing vibration and negative ion to provide a kind of, vertebra being remained on the most comfortable state, good ventilation property being provided and having by use pillow and the pillow of sanatory additional function.Application number is 200680000304.1, the Chinese patent that patent name is " producing the pillow of vibration and negative ion " discloses the pillow of generation vibration and negative ion: it comprises negative ion generating part, wherein pad coating part is formed in the top of negative ion generating pad and on pad coating part, forms bonding part to be connected to pillow, and described pillow structure is that semi-cylindrical is to hold described vibration production part and negative ion generating part.Situation is that described negative ion generating part is formed as belt-typed pad to join the bonding part be formed in pillow body to, and described liner is coated with the porous material that can control negative ion generation.Another kind of situation is that the powder that the belt-typed pad of described negative ion generating part produces liquid phase negative ion by mixing is formed as gasket shapes.
Application number is 201220532721.3, the Chinese patent that patent name is " a kind of sponge matress with moisture absorption antibacterial and deodouring function " discloses a kind of sponge matress with moisture absorption antibacterial and deodouring function, comprise mattress body and the mattress cover being covered in mattress body surface, mattress body comprises the first spongy layer and second spongy layer of upper and lower superimposed setting, described first spongy layer is environmental protection memory cotton layer, second spongy layer is high-rebound polyurethane spongy layer, first spongy layer gathers a plurality of pore, and described pore internal fixtion inlays the activated carbon granule extracted from bamboo charcoal.This structure sponge matress, in environmental protection memory cotton layer, activated carbon granule has superpower adsorption, and its negative ion produced can play the unpleasant odor eliminating human body, the humidity, clean rooms air etc. that regulate bedding, also has effect that is antibacterial, deodorizing simultaneously.
Patent CN201410233684 Quanzhou Heng Ang Trade Co., Ltd. discloses the bedclothes of anion releasing " a kind of can ", is that tourmalinite super-fine powder, TiO2 photocatalyst, silane coupling agent and foam material hybrid reaction are prepared can the bedclothes of anion releasing.
Above patent mainly by can produce the article of negative ion and bedclothes carry out simply structural combine or by surface-modifying agent, modification carried out to negative ion breeze reach the object improving negative ion breeze and urethane consistency, but negative ion breeze is being combined on bedclothes or being filled in bedclothes material of machinery, bonding force is poor between the two, do not form organic whole, have impact on the mechanical property of material to a certain extent.Particularly in porous urethane bedclothes, due to the existence of abscess, if negative ion breeze and polyurethane molecular are in conjunction with bad, the abscess avalanche of the porousness urethane bedclothes easily caused, product life is caused to shorten, the defects such as negative ion burst size is few.
In order to ensure that negative ion breeze and urethane bedclothes form organic whole, ensure that the mechanical property of the urethane bedclothes when filling negative ion breeze remains unchanged, we utilize the hydroxyl on negative ion breeze surface, make it the main raw material isocyanate reaction with polyurethane material, thus define isocyano on negative ion breeze surface grafting, improve negative ion breeze and urethane consistency, and participate in the formation of polyurethane molecular chain, form negative ion breeze and be organically combined with polyurethane molecular.
