Description
Technical field
The present invention relates to a kind of air purifying preparation.
Background technology
Air purifying preparation is applicable to various indoor environments such as newly-decorated room, automobile, office space, hotel, market.At present, mostly air purifying preparation is to cover based on fragrance the freshener aromatic etc. of peculiar smell, can not play sterilizing and removing formaldehyde, functions such as benzene series thing.And the product of independent removing formaldehyde can not be taken into account removing benzene series thing, ammonia, functions such as general volatile gas TOVC simultaneously.Chinese patent CN201110113811.9 discloses a kind of plants essential oil air purifying preparation and preparation method thereof, and it is with following raw materials by weight percent: eucalyptus essential oil 0.3, tea tree ethereal oil 0.3, argy wormwood essential oil 0.3, grape fruit essential oil 0.3, lime essential oil 0.4, lemon 0.4, peppermint essential oil 0.4, Lavender 0.6, fish pelargonium essential oil 0.9, cdear essential oil 0.4, Rosa Damascana 0.7, Pogostemon cablin essential oil 0.4, and diluent 94.6 is mixed with and forms.Be mainly used in removing in the automobile, indoor smoke and other peculiar smell purify the air of a room, and is of value to the healthy of people, its deficiency is that removal effect is not so good, can't act on PARA FORMALDEHYDE PRILLS(91,95), benzene series thing etc. volatility is polluted and the removing of bacterium class.Chlorine dioxide air cleanser that CN101143225 discloses a kind of applied range, cost is low, easy to use and keeping life is long and preparation method thereof.Air purifying preparation is made up of citric acid and the sodium chlorite aqueous solution that is potted in the bottle, and sodium chlorite aqueous solution's concentration is 3-25% mass concentration, and citric acid is sheet, granular or powdery, and the citric acid quality is 0.2-2% of sodium chlorite solution's quality.This air purifying preparation takes out citric acid in use, puts into the sodium chlorite aqueous solution, tightens bottle cap and shakes up, and namely slow release goes out chlorine dioxide, thereby reaches lasting, economical, safe purifying air.Its deficiency is to use not too convenient, to the benzene series thing, and ammonia, it is little that TOVC etc. remove the effect effect.
Summary of the invention
Technical problem to be solved by this invention provides a kind of free matter composition such as formaldehyde that sterilizing effect and interior decoration cause that has concurrently, benzene series thing, ammonia, the air purifying preparation that TOVC etc. pollutes.
This cleanser is divided into liquid reactants A component and solid-state adsorption reaction agent B component is formed.Place the B component again after wherein with the A component space of needs or environment place being sprayed earlier and adsorb decomposition, reach quick and durable completely to bacterium class and volatile formaldehyde jointly, the benzene series thing, ammonia, the reaction decomposes of TOVC etc. is removed effect.Be the omnibearing air cleaning prescription of the full effect of a kind of multi-functional goods.
For solving the problems of the technologies described above, air purifying preparation of the present invention is made up of A component liquid reactants, B component solid-state reaction adsorbent, by weight percentage,
A component liquid reactants is made by following material:
Percarbamide 15-55;
Diammonium hydrogen phosphate: 1-5
Ammonium chloride: 1-10;
Sodium lignin sulfonate: 0.5-5;
Tea Polyphenols: 0.5-3;
Soluble perfume: 0.1-5;
Deionized water: 40-79.9.
It is even that above-mentioned each composition is dissolved in deionized water for stirring in described ratio, is loaded in the bottle and sprays.Have the characteristic of urea and hydrogen peroxide after the percarbamide dissolving wherein concurrently.In water, be decomposed into urea, hydrogen peroxide and elemental oxygen, but the PARA FORMALDEHYDE PRILLS(91,95) molecular oxidation is removed and the dual highly effective reaction of amino addition at normal temperatures, has the sterilization to environment concurrently.
B component solid-state reaction adsorbent is made by following material:
Porous adsorbent class: 45-90;
Tourmaline: 5-20;
Load-reaction absorber class: 5-50.
Described porous adsorbent class: get active carbon, bamboo charcoal, treated earth, bentonite, attapulgite, diatomite, a kind of to multiple in the medical stone; Get the high temperature modified zeolite of acid-wash activation, sepiolite, one or more in the montmorillonite; Get activated alumina, 10X or 13X molecular sieve, Kiselgel A, a kind of to multiple in the vermiculite, mixed proportion is not limit.
Described load-reaction absorber class: by strong oxidizers such as one or more load acid potassium permanganates in the porous adsorbent or hydrogen peroxide, the mixed proportion of porous adsorbent is not limit.
Get final product stirring after the components in certain proportion mixing of 3 groups, being respectively charged into again in the ventilative class packing.Porous adsorbent is all selected bigger serface large pore volume class for use, utilize Van der Waals force to the benzene series thing, ammonia, TVOC etc. have the good adsorption removal effect, have the pyroelectric effect that the heat release temperature difference effect of utilizing when adsorbing excites the instant high-voltage of tourmaline concurrently, molecule to absorption has killing action, can also discharge the anion fine-purification air.The zeolite of modification, sepiolite, imvite has the performance of absorption and ion-exchange concurrently.Hyperthermia drying during the load-reaction absorbent is above by one or more (except tourmaline) 60 degree in the porous adsorbent, remove in the duct behind the contained gaseous impurity, be soaked in stirring and adsorbing in the strong oxidizers such as acid potassium permanganate or hydrogen peroxide, time discharges for waiting for no bubble, saturated the getting final product of duct absorption.Pick up the hyperthermia drying rear venting and remove the composition of surface absorption.Load-reaction absorbent PARA FORMALDEHYDE PRILLS(91,95) behind the load acid potassium permanganate, toluene, dimethylbenzene have extraordinary absorption afterreaction to remove effect.
The solid-state reaction adsorbent of B component is compared to load-reaction interpolations targetedly such as the single active carbon of the most products in market or bamboo charcoal PARA FORMALDEHYDE PRILLS(91,95), and it is efficiently obvious to remove effect.And the active carbon of market single component or bamboo charcoal are very limited to free formaldehyde molecule suction-operated through many-sided theory and practice confirmation, are that certain adsorption effect is arranged to the benzene series thing.And the absorption of the active carbon of single component or bamboo charcoal is saturated easily, and effective acting time is short, can only physical absorption, be subjected to the easy desorptions of ambient influnence such as temperature and humidity after the absorption, and can not use for a long time, repeatedly defective such as circular regeneration.And solid-state reaction adsorbent of the present invention not only has the absorption assimilation effect and has ion-exchange and chemical reaction oxidation scavenging action concurrently, discharges multiple adsorption removal effects such as instant high-voltage and anion, can use for a long time, and effect is not subject to the other factor influence.It is complete that this solid-state reaction adsorbent possesses the long action time effect than like product, and passive absorption is initiatively removed multi-pronged, acts on effects such as thorough, selects for use the raw material nonhazardous not constitute secondary pollution etc. advantage.
The present invention is compared to the market like product and has quick removing, lasting effectively advantage.Have sterilizing concurrently, remove volatility dusty gas double effects, effect thoroughly generates the low toxicity non-poisonous material.Raw material of the present invention are easy to get, prepare simple, cost is not high, make things convenient for industrialization production, and the removal effect of high, normal, basic concentration being polluted through experiment confirm many times all can reach more than 92%.
