Description
Technical field
The present invention relates to field of compound material, belong to a kind of sand that purification gas and sound-absorbing are realized by generating anion
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.
Summary of the invention
Therefore, the technical problem to be solved in the present invention is that overcome in the prior art anion excitation material overbrushing be overlying on dress
Material surface is repaired, because of the abrasion of coat, is fallen off, so that finishing material is lost the defect for removing the function of formaldehyde, to mention one
There is kind the sand of silencing function to mould partition wall.
A kind of sand with silencing function moulds partition wall, including inner panel and is arranged in the inner panel) on sand mould plate；It is special
Sign is that the sand mould plate includes the raw material of following parts by weight:
25-35 parts of quartz sand, 5-7 parts of anion-generating material, 15-20 parts of acrylic resin, polyvinyl resin 17-25
Part, 2-5 parts of coupling agent, 7-10 parts of silicon carbide whisker, 10-15 parts of adhesive and 2-3 parts of surfactant；
The anion-generating material includes magnesium aluminate spinel and the anion excitation material that is supported on magnesium aluminate spinel；
The adhesive is made of epoxyn, sodium carboxymethylcellulose and Aluminum sol.
Preferably, in the sand modeling partition wall with silencing function, in the adhesive, the epoxide-resin glue
The mass ratio of stick, the sodium carboxymethylcellulose and the Aluminum sol is (3-5): (1-2): (1-3).
Preferably, in the sand modeling partition wall with silencing function, the raw material of the sand mould plate further includes pore-creating
0.5-2 parts of agent；The pore creating material is made of dehydrated alcohol and ethylene glycol.
Preferably, in the sand modeling partition wall with silencing function, in the pore creating material, dehydrated alcohol and second two
The mass ratio of alcohol is (5-7): (1-3).
Preferably, in the sand modeling partition wall with silencing function, the raw material of the sand mould plate further includes anti-pollution
3-5 parts of agent；The anti-staining agent is the mixture of acetic acid and anti-pollution auxiliary agent, and the anti-pollution auxiliary agent is molybdenum disulfide and anhydrous sorbitol
Aliphatic ester.
Preferably, in the sand modeling partition wall with silencing function, the matter of the acetic acid and the anti-pollution auxiliary agent
Amount is than being (7-10): (1-3)；The mass ratio of the molybdenum disulfide and sorbitan fatty acid ester is (2-4): (9-13).
Preferably, in the sand modeling partition wall with silencing function, in the anion-generating material, magnalium point
The mass ratio of spar and anion excitation material is (80-100): (1-4)；The partial size of the magnesium aluminate spinel is 2-5mm；It is described
Anion excitation material is nano-tourmaline.
Preferably, in the described sand modeling partition wall with silencing function, between the sand mould plate and the inner panel according to
It is secondary to be provided with the first noise reduction layer and polyethylene board；The through-hole that several apertures are 3-5mm is offered on the polyethylene board.
