Abstract

The invention relates to a formaldehyde absorption board.The formaldehyde absorption board comprises a water-containing layer, wherein the aqueous solution of amino acid infiltrates the water-containing layer, a porous layer wraps the water-containing layer, a breathable waterproof layer wraps the porous layer, the porous layer is made of diatomite or sepiolite, the water-containing layer is made of cotton and sponges, and the aqueous solution of the amino acid is the aqueous solution of one or more of glycine, alanine, valine, leucine, tryptophan, methionine, proline, tyrosine, cysteine amino acid, asparagine, threonine, serine and glutamic acid.The formaldehyde absorption board has the advantages that the aqueous solution of the amino acid infiltrates the water-containing layer, the aqueous solution of the amino acid can outwardly infiltrate to enter the pores of the porous layer and contact with air, and the amino acid reacts with the formaldehyde so as to remove the formaldehyde; the formaldehyde absorption board is of a board shape, the contact area with the air can be increased, and the formaldehyde removing effect is increased.

Description

Formaldehyde absorbing plate
Technical field
The present invention relates to a kind of formaldehyde absorbing plate.
Background technology
Building materials, furniture that current house decoration is used usually bring formaldehyde pollution, and the method removing formaldehyde common at present is to arrange charcoal bag, but charcoal bag is little with air contact area, and adsorption effect is unsatisfactory.
Summary of the invention
The technical problem to be solved is: provides a kind of formaldehyde absorbing plate, has bigger air contact area, can adsorption removal formaldehyde faster.
The technical solution adopted for the present invention to solve the technical problems is:
Formaldehyde absorbing plate, including water-bearing layer, described water-bearing layer is impregnated with amino acid whose aqueous solution, and water-bearing layer is wrapped with porous layer, and porous layer is wrapped with ventilative water blocking layer；Described porous layer material is kieselguhr or meerschaum.
Further, described water-bearing layer material is Cotton Gossypii, sponge.
Further, described amino acid whose aqueous solution is the aqueous solution of one or more in glycine, alanine, valine, leucine, tryptophan, methionine, proline, TYR, cysteine, agedoite, threonine, serine and glutamic acid.
Further, described ventilative water blocking layer material is non-woven fabrics.
The invention has the beneficial effects as follows: this formaldehyde absorbing plate, water-bearing layer has amino acid whose aqueous solution, can outwards infiltrate in the pore entering porous layer, with air contact, aminoacid and formaldehyde reaction, make formaldehyde removing, and this device is tabular, the contact area with air can be increased, increase formaldehyde removing effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the formaldehyde absorbing plate of the present invention；
In figure, accompanying drawing is labeled as: ventilative water blocking layer 1, porous layer 2, water-bearing layer 3.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Formaldehyde absorbing plate, including water-bearing layer 3, described water-bearing layer 3 is impregnated with amino acid whose aqueous solution, and water-bearing layer 3 is wrapped with porous layer 2, and porous layer 2 is wrapped with ventilative water blocking layer 1.
Above-mentioned formaldehyde absorbing plate, being impregnated with amino acid solution in its water-bearing layer 3, it is possible to infiltration enters in the pore of porous layer 2, contaminated air enters into porous layer 2 through ventilative water blocking layer 1 and contacts with Freamine Ⅲ, formaldehyde and aminoacid react, it is achieved remove the purpose of formaldehyde.
Concrete, water-bearing layer 3 can store and adsorb amino acid solution, for instance can be material be the material of Cotton Gossypii, sponge etc.
Amino acid whose aqueous solution can be the aqueous solution of one or more in glycine, alanine, valine, leucine, tryptophan, methionine, proline, TYR, cysteine, agedoite, threonine, serine and glutamic acid.
Porous layer 2 can be provided with the plate of intensive pore, it is preferred that can be that kieselguhr, meerschaum, bentonite or activated carbon etc. have punctulate solid material.
Ventilative water blocking layer 1 is used for stoping or reduce aqueous solution and flows outwardly, and allows the material of air permeable, it is preferred that can be non-woven fabrics.
