Description
Technical field
The invention belongs to the preparation field of formaldehyde absorbent, particularly relate to a kind of preparation method of high-efficiency absorber for formaldehyde.
Background technology
Along with the raising of people's living standard and the improvement of living conditions, a large amount of new decorative materials are widely used in the house decoration, and the indoor environmental pollution that is caused thus also becomes serious day by day.Formaldehyde is a kind of colourless easily molten irritative gas, and formaldehyde can be absorbed by the body through respiratory tract, skin, and health is had negative effect.The problem of the free formaldehyde of indoor hardware fitting release in recent years more and more draws attention, when people live in the environment that formaldehyde exceeds standard for a long time, symptoms such as stomachache, breathing problem, hepatic injury, renal failure, chromosome pathology can occur, so the protection of PARA FORMALDEHYDE PRILLS(91,95) has become urgent problem.Improvement people to indoor air pollutants have developed many methods in succession, mainly contain chemical reaction method, light-catalyzed reaction method and absorption method etc., and the whole bag of tricks respectively have its characteristics under particular environment.Wherein, absorption method mainly is to utilize some material that adsorption capacity is arranged to adsorb harmful components and reach to eliminate to be harmful to the purpose of polluting.Adsorbent commonly used mainly contains active carbon, silica gel, zeolite etc.Absorption method by force, does not cause advantages such as secondary pollution owing to have enrichment function, becomes the effective ways of administering low concentration unwanted gas in recent years.
Summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method of high-efficiency absorber for formaldehyde, and this preparation method is simple, cost is low, has good economic benefit, is applicable to suitability for industrialized production; And the formaldehyde high-efficiency adsorbents adsorb formaldehyde effect that makes is remarkable, and non-secondary pollution can use for a long time.
The preparation method of a kind of high-efficiency absorber for formaldehyde of the present invention comprises:
(1) carboxylic acid part and nitrate were dissolved in the solvent in 1: 2 in molar ratio～2: 1, synthesize under 70～180 ℃ by hydrothermal synthesis method, the reaction time is 12～20 hours; Filter and remove mother liquor acquisition crystalline material, crystalline material is washed,, carry out mechanical crushing after the oven dry to remove unreacted organic ligand and metal ion with deionized water;
(2) will synthesize good crystal and carry out the vacuum activation processing under 120 ℃～200 ℃ temperature, vacuum is 0.06～0.08Torr, and soak time is 4～25 hours.
Carboxylic acid part in the described step (1) is selected from one or more the mixture in terephthalic acid (TPA), phthalic acid, M-phthalic acid, the trimesic acid;
Nitrate in the described step (1) is one or more the mixture that is selected from copper nitrate, zinc nitrate, ferric nitrate, the manganese nitrate;
Solvent in the described step (1) is volume ratio DMF: ethanol: the mixed solvent of water=1: 1: 1.
The formaldehyde high-efficiency adsorbent of the present invention's preparation can be used for interior decoration field, automotive interior processing with fresh air, industrial protection mouth mask, hospital ward etc., and also can be applied to the surface of textile in the mode of coating, or be applied in the mode of filling.
Beneficial effect
(1) preparation method of the present invention is simple, cost is low, has good economic benefit, is applicable to suitability for industrialized production;
(2) this formaldehyde high-efficiency adsorbents adsorb formaldehyde effect is remarkable, and non-secondary pollution can use for a long time.
