Description
Technical field
The present invention relates to technical field of air purification, be specifically related to a kind of air purifying preparation and preparation method thereof.
Background technology
Adsorption cleaning method is at present for one of method most widely used in method for treating indoor air pollution.Wherein: activated carbon of sorbent has good adsorption cleaning ability, but price is relatively expensive.In recent years, some natural minerals are as novel sorbing material, and have aboundresources, cheap, adsorptivity strong, the features such as product is environmentally friendly, receive and pay close attention to widely, as zeolite, diatomite, montmorillonite, rectorite etc.For obtaining higher adsorption cleaning disposal ability, need to purify, the deep processing transformation such as modification to natural minerals, or carry out the compound of multiple natural minerals, this has become the emphasis of environment mineral material research.
Publication number is that the patent of invention of CN1554447 discloses a kind of super fine active compound adsorptive indoor air purifying agent, specifically by the Concave-convex clay rod after activation process and super-fine processing or sepiolite clay and zeolite by suitable proportioning mixing, carry out combination granulation and dry, mix according to a certain percentage with granular active carbon again, to obtain final product.The described air purifying preparation of this invention has good air purification effect, but its preparation method has the following disadvantages: (1) need soak activation to mineral material acid or alkali, use clear water rinsing afterwards, producing a large amount of waste water in preparation process needs process, and environmental protection pressure is large; (2) by the dried mineral material ultra-fine grinding of activation to 800-2000 order, need consume energy higher; (3) with the active carbon of 5-60%, cost need be increased.
Summary of the invention
The technical problem to be solved in the present invention is to provide in a kind of preparation process and produces and air purifying preparation of good air purification effect and preparation method thereof without waste water.
The preparation method of air purifying preparation of the present invention, comprises the following steps:
1) get α sepiolite, pulverize, soak 7-10 days, filter, in gained filter residue, add the lime solution immersion 7-10 days that mass concentration is 1-1.5%, filter, filter residue and drying, pulverize, obtain the sepiolite after ripening;
2) get itaconic acid to add water and be made into the solution that mass concentration is 10-20%, obtain itaconic acid solution;
3) take the sepiolite after ripening by the weight proportion of 60-80:20-40 and itaconic acid solution carries out granulation, under 120-200 DEG C of condition, activate 1-3h afterwards, namely obtain air purifying preparation.
The step 1 of above-mentioned preparation method) in, the addition of described water is soaking the water yield required for 7-10 days for meeting α sepiolite, generally, the α sepiolite of 1kg needs the water adding 10-15kg could meet 1kg α sepiolite to soak 7-10 days under normal temperature condition.Described lime solution be by according to concentration requirement a certain amount of quick lime is placed in water dissolve should and obtain.The addition of described lime solution is after water soaking, filter the 1-3% of gained filter residue weight, preferably after water soaking, filters 2% of gained filter residue weight.In this step, normally α sepiolite powder is broken to 60-100 order, then before soaking; Normally by soaking through lime solution, filter, the filter residue of dry gained is crushed to 80-120 order.Special ripening is carried out to sepiolite, sepiolite of can effectively purifying, make sepiolite content in the sepiolite after this process to reach 80-85%, substantially increase the adsorption cleaning disposal ability of sepiolite.
The step 2 of above-mentioned preparation method) in, preferably get itaconic acid and add water and be made into the solution that mass concentration is 15%.
The step 3 of above-mentioned preparation method) in, preferably take the sepiolite after ripening by the weight proportion of 65-75:25-35 and itaconic acid solution carries out granulation, be more preferably and take the sepiolite after ripening by the weight proportion of 70:30 and itaconic acid solution carries out granulation.
The present invention also comprises the air purifying preparation that said method prepares.
Compared with prior art, feature of the present invention is:
1, only need sepiolite water and lime solution to soak respectively to the modifying processing step of sepiolite, do not relate to the use of the reagent such as acid, alkali in process, thus the pollution of environment can not be caused, omit the sewage disposal operation existed in prior art; On the other hand, sepiolite water and lime solution immersion are filtered the filtrate obtained afterwards and can be repeated to use, as water can continue for soaking in the production of next round, lime solution soaks the preparation that rear filtrate of filtering gained then can continue on for lime solution, without waste water, waste discharge in whole modifying process.
2, the present invention first carries out special ripening effectively to improve its adsorption cleaning disposal ability to sepiolite, the sepiolite after ripening and itaconic acid is carried out mixing rear granulation, activation more afterwards, to improve the clean-up effect of gained air purifying preparation further.
