Detailed description of the invention
Hereinafter, describing the preferred embodiment of the present invention and the physical property of each composition in detail, this is simply so that technology belonging to the present invention is led
The degree that the those of ordinary skill in territory can easily carry out an invention describes in detail, and the technological thought of the present invention and category are also
The most therefore this it is confined to.
The preparation method of the automobile VOC abatement plate of the present invention includes: melt-blown nonwoven layer of cloth forming step
S101, melt-spraying spinning macromolecule resin forms a diameter of 1 to 10 micron and have 20 to 500g/m2Surface density
Nonwoven layer 10；Dispersion steps S103, in the nonwoven layer formed by above-mentioned melt-blown nonwoven layer of cloth forming step S101
10 to 300g/m is disperseed in 102The VOC abatement powder 11 of amount；Surface layer Stacking steps S105,
By above-mentioned dispersion steps S103 disperseed VOC abatement powder 11 nonwoven layer 10 upper side and
Bottom surfaces laminate surface layer 20；Adhesion step S107, makes the duplexer prepared by above-mentioned surface layer Stacking steps S105
Bondd by heating roller；And forming step S109, utilize press fixture to make by above-mentioned adhesion step S107
And the duplexer bondd shapes.
In above-mentioned melt-blown nonwoven layer of cloth forming step S101, it is micro-that melt-spraying spinning macromolecule resin forms a diameter of 1 to 10
Rice and there is 20 to 500g/m2The nonwoven layer 10 of surface density.
Above-mentioned macromolecule resin comprises more than one that select from TPO, polyamide-based and polyesters, by melt-blown
Mode is with 20 to 500g/m2Surface density spinning, as it has been described above, a diameter of with the macromolecule resin of melt-blown mode spinning
1 to 10 micron, and it is denoted as the self-adhesive (self-bonding) of three-dimensional fiber aggregation, thus play and condense upon
State scattered VOC in dispersion steps S103 and cut down powder 11 to suppress VOC to cut down
Powder is to the effect of outside drain.
Now, if the surface density of nonwoven layer 10 is less than 20g/m2, then dispersion can be supported in above-mentioned dispersion steps S103
VOC abatement powder 11 ability decline, thus be not provided that the inside of automobile produce volatility
The plate of the abatement excellent of organic compound, if the surface density of above-mentioned nonwoven layer 10 is more than 500g/m2, then system is increased
The weight of standby VOC abatement plate and preparation expense.
In above-mentioned dispersion steps S103, in the nonwoven layer 10 formed by above-mentioned melt-blown nonwoven layer of cloth forming step S101
Middle dispersion 10 to 300g/m2The VOC abatement powder 11 of amount, and, by via above-mentioned melt-blown nothing
Spin dispersing volatile organic compound abatement powder 11 in the nonwoven layer 10 that layer of cloth forming step S101 is formed, and utilize
Physical method adsorbs or by chemical method decomposing volatile organic compound, thus gives abatement function.
If the amount of scattered VOC abatement powder 11 is less than 10g/m in above-mentioned dispersion steps S1032,
The abatement effect of the VOC then produced at automotive interior reduces, if above-mentioned VOC abatement
The dispersion amount of powder 11 is more than 300g/m2, then the non-woven fabrics prepared by above-mentioned melt-blown nonwoven layer of cloth forming step S101
The cohesive force of layer 10 declines, and likely produces and peeled off by the surface layer 20 of above-mentioned surface layer Stacking steps S105 stacking
Phenomenon.
It addition, a diameter of 1 micron to 1 millimeter of above-mentioned VOC abatement powder 11, above-mentioned volatility
Organic compound abatement powder 11 comprises selection from porous natural minerals, metal-oxide and amine organic compound
More than one, mentioned component the VOC abatement powder 11 formed is adsorbed or by changing by physical method
Method decomposing volatile organic compound, and make relief performance outstanding.
Now, it is preferable that above-mentioned porous natural minerals comprise from kieselguhr, zeolite, silicon dioxide, kaolinite, angstrom
In Lip river stone, sericite, montmorillonite, bentonite and activated carbon select more than one, above-mentioned metal-oxide comprises from two
In titanium oxide, zinc oxide, niobium type oxide, zirconium oxide, titanate and tantalates select more than one, above-mentioned amine
Organic compound comprise from ammonium sulfate (CAS No.7783-20-2), tetramethyl thiourea (CAS No.2782-91-4), six
Methine tetramine (CAS No.100-97-0), hexanediol acid (CAS No.124-04-9) and adipic acid hydrazides (CAS No.
1071-93-8) in select more than one.
In above-mentioned surface layer Stacking steps S105, disappeared by above-mentioned dispersion steps S103 dispersing volatile organic compound
Subtract stacking surface layer 20 in the upper side of the nonwoven layer 10 of powder 11 and bottom surfaces, above-mentioned surface layer Stacking steps S105
Realize by the following method, i.e. cutting down powder by above-mentioned dispersion steps S103 dispersing volatile organic compound
In the upper side of the nonwoven layer 10 of 11 and bottom surfaces, stacking surface density is 10 to 50g/m2And comprise from TPO, gather
More than one the surface layer 20 selected in amide-type and polyesters.
If by above-mentioned surface layer Stacking steps S105 laminate surface layer 20, then can suppress to be scattered in waving of nonwoven layer 10
The property sent out organic compound abatement powder 11 flows out to outside, and improves the automobile volatile organic prepared by the present invention
The presentation quality of compound abatement plate.
Now, if the surface density of above-mentioned surface layer 20 is less than 10g/m2, then the volatility of above-mentioned nonwoven layer 10 it is scattered in
Organic compound abatement powder 11 is likely to the outside outflow of plate, if the surface density of above-mentioned surface layer 20 is more than 50g/m2
Weight, then prepare VOC abatement plate during can reduce and the bonding of above-mentioned nonwoven layer 10
Power, and likely it is peeling phenomenon.
In above-mentioned adhesion step S107, the duplexer prepared by above-mentioned surface layer Stacking steps S105 is made to pass through heating roller
Bond, and, make the duplexer prepared by above-mentioned surface layer Stacking steps S105 pass through with 160 to 200 DEG C
The warmed-up roller of temperature, bond above-mentioned nonwoven layer 10 and above-mentioned surface layer 20.
If above-mentioned duplexer passes through the warmed-up roller of temperature with 160 to 200 DEG C via above-mentioned adhesion step S107, then go up
State nonwoven layer 10 and the melt surface of above-mentioned surface layer 20 and show cohesive force, by above-mentioned nonwoven layer 10 and above-mentioned
Surface layer 20 bonding is got up.
Now, if the temperature of above-mentioned roller is less than 160 DEG C, the surface of the most above-mentioned nonwoven layer 10 and above-mentioned surface layer 20 is not
Melted, and reduce the effectiveness of bonding process, if the temperature of above-mentioned roller is higher than 200 DEG C, then can be because of above-mentioned nonwoven layer 10
Area excessively melted, adsorbable VOC reduce, the effectiveness of VOC abatement plate
Decline, and the phenomenon that the form likely producing plate deforms.
In above-mentioned forming step S109, utilize press fixture to make by the duplexer of above-mentioned adhesion step S107 bonding and shape,
Further, utilize the fixture of easily dimmable pressure to make by the duplexer of above-mentioned adhesion step S107 bonding and shape, and make above-mentioned
Duplexer has regulation shape.
Now, by the form of the products formed of above-mentioned forming step S109 molding according to being suitable for the form of top of plate and suitable
Different with position, above-mentioned fixture is used for automobile sheetsteel, as long as easily dimmable pressure, is just not particularly limited, can use
Any one.
