Embodiment according to the present utility model, it is attached on 1 surface of air-conditioning filter net in order to improve dirt resistance coatings composition
Put forth effort, before coating dirt resistance coatings composition, air-conditioning filter net 1 can be cleaned, such as using spray, impregnating mode
It is cleaned.
Embodiment according to the present utility model, in order to guarantee preferable dust-proof effect, dust-proof coating 1000 with a thickness of 0.1
Micron~10 microns, for example, can be 0.1 micron, 0.5 micron, 1 micron, 2 microns, 3 microns, 4 microns, 5 microns, 6 microns, 7
Micron, 8 microns, 9 microns or 10 microns.Dust-proof effect is preferable as a result, and guarantees the micro-nano knot of the dust-proof coating surface of the thickness
Structure 1100 has the protrusion of suitable height；If the thickness of dust-proof coating 1000 is less than 0.1 micron, dust-proof 1000 integral thickness of coating
It is relatively thin, the uniformity of the meeting dust-proof coating 1000 of relative reduction, and then influence attachment of the dust-proof coating 1000 on air-conditioning filter net 1
Power, and then relative reduction dust-proof effect；If dust-proof 1000 thickness of coating is greater than 10 microns, the waste of raw material will cause, and due to
Twine 120 is relatively thin, the pressure that blocked up dust-proof coating meeting relative increase applies twine 120, and then may destroy twine
120, in addition, the gap between twine 120 is smaller, thicker dust-proof coating 1000 can further reduce twine 120 relatively
Between spacing, in this way, the working efficiency of the air conditioner using the air-conditioning filter net 1 may be will affect.
Embodiment according to the present utility model, in order to obtain the micro-nano structure 1100 of the protrusion with suitable height, oxidation
The partial size of composition granule is 10 nanometers~200 nanometers (i.e. the partial size of oxide particle is distributed in 10 nanometers~200 nanometer ranges),
For example, can be 10 nanometers, 20 nanometers, 30 nanometers, 40 nanometers, 50 nanometers, 60 nanometers, 70 nanometers, 80 nanometers, 90 nanometers, 100
Nanometer, 120 nanometers, 140 nanometers, 160 nanometers, 180 nanometers or 200 nanometers.Since micro-nano structure 1100 is by preparing dust-proof painting
What the oxide particle of layer 1000 was formed, the big of the big minor adjustment micro-nano structure 1100 of adjusting oxide particle partial size can be passed through
It is small, and the oxide particle within the scope of this can make the protrusion in micro-nano structure 1100 have suitable height, guarantee dust-proof
Coating 1000 has preferable dust-proof effect；If the micro-nano structure 1100 that the partial size of oxide particle less than 10 nanometers, is formed
Relatively unobvious, i.e., the height of the protrusion in micro-nano structure 1100 is relatively low, cannot reduce dust and dust-proof coating well
The adhesion strength of 1000 contact area, i.e. dust on dust-proof 1000 surface of coating is relatively large, and then the dust-proof painting of relative reduction
The dust-proof effect of layer 1000；If the partial size of oxide particle is greater than 200 nanometers, opposite will increase aoxidizes in dust-proof coating 1000
Gap between composition granule, and then adhesive force of the dust-proof coating 1000 on air-conditioning filter net 1 is reduced, and then dust-proof painting may occur
The phenomenon that layer 1000 falls off, finally influences dust-proof effect, in addition, twine 120 is relatively thin, and the gap between twine 120 is smaller, adopts
The stability for the dust-proof coating 1000 for being not easy to the preparation of dust-proof coating with the oxide particle of greater particle size, and being prepared
It is relatively bad, finally influence dust-proof effect.It should be noted that the protrusion in micro-nano structure 1100 refers to dust-proof 1000 table of coating
The protrusion that the micro-nano structure 1100 in face is formed.
Embodiment according to the present utility model, in order to improve the dust-proof effect of dust-proof coating 1000, referring to Fig.1, micro-nano knot
The height H of protrusion in structure 1100 is 10 nanometers~400 nanometers, for example, can receive for 10 nanometers, 20 nanometers, 30 nanometers, 40
Rice, 50 nanometers, 60 nanometers, 70 nanometers, 80 nanometers, 90 nanometers, 100 nanometers, 120 nanometers, 140 nanometers, 160 nanometers, 180 receive
Rice, 200 nanometers, 250 nanometers, 300 nanometers, 350 nanometers or 400 nanometers, wherein height of projection is greater than oxide particle maximum grain
The protrusion of diameter is as caused by the superposition of two or more oxide particles, and height of projection is larger but is less than oxide particle most
Large-sized protrusion is it could also be possible that caused by superposition as multiple small size particles.The micro-nano structure 1100 can be big as a result,
The big contact area for reducing dust and dust-proof 1000 surface of coating, and then greatly improve the dust-proof effect of dust-proof coating 1000；Phase
To the micro-nano structure 1100 in above range, if the height of the protrusion in micro-nano structure 1100 is lower than 10 nanometers, micro-nano structure
1100 is relatively unobvious, cannot reduce the contact area of dust and dust-proof coating 1000 well, i.e., dust is in dust-proof coating
Adhesion strength on 1000 surfaces is relatively large, and then the dust-proof effect of the dust-proof coating 1000 of relative reduction；If micro-nano structure 1100
In the height of protrusion be higher than 400 nanometers, then on the one hand need to use the biggish oxide particle of partial size, and the biggish oxidation of partial size
Composition granule opposite can increase intergranular gap in dust-proof coating 1000, and then reduce dust-proof coating 1000 in air-conditioning filter net 1
On adhesive force, finally influence dust-proof effect, in addition, twine is thinner, and the gap between twine 120 is smaller, using larger grain
The stability for the dust-proof coating 1000 that the oxide particle of diameter is not easy to the preparation of dust-proof coating 1000, and is prepared is also opposite
It is bad, finally influence dust-proof effect；On the other hand it needs more multiple oxide particles to be superimposed to be formed, protrusion can be made unstable, hold
Easily receive extraneous damage.
Embodiment according to the present utility model, in order to enable dust-proof coating 1000 is preferably attached to air-conditioning filter net 1
