Description
Technical field
The present invention relates to a kind of stationery adsorbent, its preparation method and method for using that can be used in purifying formaldehyde in the air.
Background technology
Contain formaldehyde mostly in present various finishing, the ornament materials; The situation that confined space formaldehyde exceeds standard in indoor, the car of people work, life etc. is very serious, and various thereupon purifying formaldehyde materials also occur in succession, the adsorbent of similar active carbon; With titanium dioxide and noble metal is the catalyst of representative; Various release fragrance are covered the air freshener of formaldehyde peculiar smell etc., and product form is also varied, nonwoven fabric charcoal bag, air purifier, spray, coagulating agent etc.
Existing formaldehyde adsorbent is realized the purification of PARA FORMALDEHYDE PRILLS(91,95) mostly with the form of the form of charcoal bag or clarifier; On the one hand; Because stopping of outer nonwoven fabric makes adsorbent abundant inadequately with contacting of air, the ability that purifies formaldehyde descends greatly; Though the clean-up effect of clarifier is better, expensive price also lets a lot of families hang back; On the other hand, existing formaldehyde adsorbent all is through realizing purifying to being dispersed into the approach that airborne formaldehyde adsorbs, and before being adsorbed, the dispose procedure of formaldehyde has caused adverse effect to human body.Though the formaldehyde decomposition catalyst of existing titanium dioxide and noble metal is decomposing formaldehyde thoroughly; But efficient is lower, and price is higher simultaneously, and the taste of formaldehyde is just temporarily covered in the effect of air freshener; Can not really remove formaldehyde, not have the purpose of protection indoor occupant respiratory health.
Chinese invention patent ZL200510035029.4 discloses a kind of paper or cloth of eliminating indoor formaldehyde and indoor organic volatile matter; It is to be carrier with papery or dry goods material; Formaldehyde is eliminated solvent adsorption on this papery or dry goods material; And dry the acquisition, wherein, formaldehyde is eliminated solvent and is formed (percentage by weight) by following component: amino-compound such as urea 45%, cyanamide compounds such as dicyandiamide 15%, carboxyl methyl cellulose 8.5%, nano titanium oxide 1.5% and water 30%.This is eliminated in paper or the cloth of indoor formaldehyde and indoor organic volatile matter, and active constituent content is less, and purification efficiency is not high, and it mainly carries out photocatalysis Decomposition formaldehyde with nano titanium oxide, thereby receives the restriction of illumination condition.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes prior art; A kind of improved formaldehyde absorption paper is provided; It is cheap, formaldehyde advantages of good adsorption effect and not limited by illumination condition, and can be attached at the inwall of sheet material, and the formaldehyde that sheet material is discharged directly absorbs.
The present invention also will provide a kind of preparation method of formaldehyde absorption paper simultaneously, and its technology is simple, and cost is lower.
The present invention also will provide a kind of method for using of formaldehyde absorption paper, and this method not only can guarantee IAQ, and the formaldehyde that also can break sheet material discharges balance, promotes sheet material formaldehyde to discharge, and reduces the cycle that sheet material formaldehyde discharges.
For solving above technical problem, a kind of technical scheme that the present invention takes is: a kind of formaldehyde absorption paper, it quantitatively is 140～160g/m
2, thickness is 0.2～0.3mm, air permeability>=200L/m
2S Δ 127Pa, bursting strength>=300KPa, the aperture is 30～100 μ m, formaldehyde adsorbance>=150mg/g, this formaldehyde absorption paper through with the formaldehyde adsorbent solution with after papermaking wood oar mixes, warp is pulled an oar, and manufactures paper with pulp, batches and make.
The another technical scheme that the present invention takes is: a kind of preparation method of formaldehyde absorption paper, it comprises the steps:
(1), with potassium permanganate and NaOH or potassium hydroxide or the mixture of the two in molar ratio 3～7: 15～18 ratio be formulated as the A solution that potassium permanganate content is 15g/L～25g/L;
(2), with zinc nitrate or zinc sulfate or the mixture of the two and cerous nitrate in 6～12: 1～2 ratio is mixed with the mixed solution that zinc ion concentration is 0.3～0.8mol/L; In this mixed solution, add papermaking wood pulp, gum rosin and aluminum sulfate then and obtain B solution; Wherein the amount of papermaking wood oar is 40～50g/L interpolations that be as the criterion to do the content of component in B solution, and gum rosin and aluminum sulfate are 1～6g/L and 1～3g/L interpolation by the content in B solution respectively;
(3), be 1～4: 1 according to the volume ratio of A solution and B solution, A solution is slowly joined in the B solution, stir, until reacting completely, promptly get said formaldehyde through pull an oar, manufacturing paper with pulp, batch at last and adsorb paper.
Preferably, in the step (1), the mol ratio of potassium permanganate and NaOH or potassium hydroxide or the mixture of the two is 5～6: 16～17, and the content of described potassium permanganate in A solution is 18～22g/L.In the step (2), make in the said mixed solution, zinc ion concentration is 0.5～0.7mol/L.The mol ratio of zinc nitrate or zinc sulfate or mixture of the two and cerous nitrate is 9～10: 1～2.Gum rosin is that 2～3g/L adds according to the content in B solution.In the step (3), with A solution and B solution 2～3: 1 mixed by volume.
The invention still further relates to the formaldehyde absorption paper that a kind of above-mentioned preparation method prepares, it quantitatively is 120～160g/m
2, thickness is 0.2～0.3mm, air permeability>=200L/m
2S Δ 127Pa, bursting strength>=300KPa, the aperture is 30～100 μ m, formaldehyde adsorbance>=150mg/g.
The another technical scheme that the present invention takes is: the method for using that a kind of above-mentioned formaldehyde adsorbs paper: formaldehyde is adsorbed paper be attached to the body surface that produces formaldehyde.The object of generation formaldehyde is indoor furniture for example.
Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
Formaldehyde of the present invention absorption paper is with formaldehyde adsorbent solution and the form that causes paper after papermaking wood oar directly mixes, and it is that nanoscale and content can be very high that formaldehyde adsorbs in the paper active component, advantages of good adsorption effect; Particularly in use, can it be attached at the inwall of sheet material, the formaldehyde that sheet material is discharged directly absorbs; Not only can guarantee IAQ; The formaldehyde that also can break sheet material discharges balance, promotes sheet material formaldehyde to discharge, and reduces the cycle that sheet material formaldehyde discharges.In addition, the preparation of formaldehyde absorption paper of the present invention is simple, cheap.
