Description
Technical field
The utility model relates to field of compound material, belong to a kind of by generating anion realization purification gas and sound-absorbing
Sand mould partition wall.
Background technique
It is well known that will use a large amount of coating and adhesive during the finishing in house, and coating and adhesive
In can usually contain a large amount of formaldehyde.It will lead to that indoor air formaldehyde content is exceeded in this way, to cause the damage to human body.Mesh
The preceding common method for removing indoor formaldehyde pernicious gas is mainly physical method and chemical method.Wherein physical method is to use
The porous materials such as active carbon adsorb indoor formaldehyde gas, to realize the effect for reducing indoor harmful gas content.But
It is this quadrat method, due to the limited sorption capacity of active carbon, so the removing of PARA FORMALDEHYDE PRILLS(91,95) is not highly desirable.Chemical method is main
It is to have reached the effect for removing the harmful substances such as indoor formaldehyde by using chemical reagent such as formaldehyde scavengers.But this kind of side
Although method can timely remove the formaldehyde in room air, the formaldehyde being adsorbed in construction material can not be removed.
Since the mode of above-mentioned removing indoor formaldehyde is all there are biggish defect, and then research is removed indoor first by people
On the directional steering of aldehyde finishing material.For example, to disclose a kind of PVC wood plastic compound by Chinese patent literature CN104895285A
Floor, this method are that scratch resistance antimicrobial paint surface layer and anion reaction paint are from top to bottom successively coated on PVC wood plastic clad plate
Surface layer and nano water-proof sealant layer.Air or vapor pass through the micropore or hole of scratch resistance antimicrobial paint surface layer, anti-with anion
Answer in lacquer painting layer the anions excitation material such as negative ion powder to contact, generated under the action of these anion excitation materials bear from
Son, later by negative ion decomposition formaldehyde in air, to realize the function of removing indoor formaldehyde.Since anion reacts lacquer painting
Layer is set to the surface of PVC wood plastic clad plate, with the extension of use time, be easy to cause the abrasion of lacquer painting, pollutes and take off
It falls, to lose the function of removing formaldehyde.
Sand plastic composite materials are a kind of emerging materials, are with sandstone and resin, polyethylene, polypropylene, polyvinyl chloride
It is prepared Deng mixing, then through plastic processings such as extruding, molding, injection moldings.Sand plastic composite materials its not only have it is outer
Table feature beautiful and generous, but also have that hardness is high, good flame resistance, and also there is good anti-corrosion, antibacterial and mothproof etc.
Performance.But be mostly at present the research concentrated on in its bending strength, thermal and insulating performance to the research of sand plastic composite materials,
It is studied in purification gas less.If can prepare it is a kind of with the complex sand moulding material for removing formaldehyde gas, will can
So that sand plastic composite materials are widely used.

Gas anion induces measurement examination, and test data is shown in Table 2.
Table 2
| The negative aeroion amount of inducing, a/s.cm2 | |
| Sand mould plate A | 1000 |
| Sand mould plate B | 1145 |
| Sand mould plate C | 1220 |
| Sand mould plate D | 1255 |
| Sand mould plate E | 1280 |
| Sand mould plate F | 670 |
3. couple sand mould plate A-F removes the aptitude tests of formaldehyde, test data is shown in Table 3.
Test method: being cut into 5cm × 5cm × 3cm thin plate for sand mould plate A-F, after which is placed in outdoor 3 days, wipes
Wipe clean thin sheet surface, be placed in the container of 5L, to container vacuum-pumping, backward container be filled with containing concentration of formaldehyde
15mg/m3Initial testing gas at 25 DEG C of temperature, stand 48h until air pressure restores to 1 atmospheric pressure in container.Later from
1L gas is extracted in container, the gas of extraction is named as termination test gas, and detection terminates the changing value of concentration of formaldehyde in gas.
Concentration of formaldehyde is tested according to the prescriptive procedure in standard GB-13197-91, i.e., with a certain amount of absorbing pure water gas
Formaldehyde in body, later with the formaldehyde in spectrophotometric determination water.Formaldehyde collecting rate calculates according to the following equation:
Wherein, A0It is respectively initial testing gas and the absorbance for terminating test gas with Ax.
Table 3
| Formaldehyde collecting rate, % | |
| Sand mould plate A | 90.24% |
| Sand mould plate B | 91.13% |
| Sand mould plate C | 93.51% |
| Sand mould plate D | 93.69% |
| Sand mould plate E | 94.01% |
| Sand mould plate F | 69.23% |
Test thin plate after outdoor placement 3 days, anti-staining agent sand mould plate B remove formaldehyde ability be obviously not so good as added with
The sand mould plate C-E of anti-staining agent removes the ability of formaldehyde；
Sand mould plate F instead results in the ability decline of the removing formaldehyde of sand mould plate due to using different anti-staining agents.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes among the protection scope created still in the utility model.
