Abstract
The invention discloses a kind of method except formaldehyde coating and its obtained remove formaldehyde filter, set on carrier and remove formaldehyde catalyst coating and catalyst fixed bed, catalyst fixed bed is arranged on catalyst coat outer layer, catalyst fixed bed will be fixed well except formaldehyde catalyst coating, prevent it from coming off, and avoid catalyst exposure and absorb moisture content in atmosphere, reduce the activity of catalyst；Catalyst fixed bed will not will remove formaldehyde catalyst coating covering parcel simultaneously, ensure that the effect except formaldehyde.
Description
Technical field
The present invention relates to be made except formaldehyde process, especially a kind of method and application this method except formaldehyde coating
Remove formaldehyde filter.
Background technology
Current air-conditioning, the performance of air purifier have strict antibacterial, purification to require that air conditioner filter has certain
Can stamp the mark of " purification air-conditioning " except the function of formaldehyde, air-conditioning；After standard appearance, the State Bureau of Quality Supervision is in the market
" purification " electrical equipment is spot-check, and testing result shows that " purification air-conditioning " of multiple brands is unable to reach the requirement of national standard, has
Functional circuit be that the filter of prestowage has certain function of removing formaldehyde, but the performance of functional circuit complete machine is joined with Standard
Number greatly differs from each other, or even the functional circuit having has no function of removing formaldehyde and can sayed, it is necessary to develop new purification techniques to make complete machine
Purification function meets the requirement of national standard.
In addition, prior art removes formaldehyde catalyst coating, when making in order to play the effect of catalyst to greatest extent,
The adhesive ratio of addition is less, and catalyst coat can come off in use, filter is reduced except formaldehyde performance, and urge
Agent exposes in atmosphere the moisture content in easily absorption air, greatly reduces the activity of catalyst；But if add excessively
Adhesive, or selection adhesive are improper, and catalyst can be completely wrapped again, can not play the effect of it removes formaldehyde.
The content of the invention
In order to overcome prior art easily to be come off except formaldehyde coating, and moisture content in meeting absorption air, influence remove effect of formaldehyde
Deficiency, the invention provides one kind to prevent catalyst coat from coming off, and what catalyst performance can give full play to removes formaldehyde coating
Method.
The technical solution adopted for the present invention to solve the technical problems is：
It is a kind of except the method for formaldehyde coating,
One carrier is provided first；
Mixing will be configured in proportion except formaldehyde catalyst coating each component, and be sufficiently stirred；
Except formaldehyde catalyst coating any of spraying, immersion, coating mode will be used to be added to carrier；
It is dried by the way of the one or more combination in natural drying, pneumatic conveying drying, microwave drying or vacuum drying；
Catalyst fixed bed each component is configured into mixing in proportion, and is sufficiently stirred；
Catalyst fixed bed is added to except formaldehyde catalyst coating surface using any of spraying, immersion, coating mode；
Carried out again by the way of the one or more combination in natural drying, pneumatic conveying drying, microwave drying or vacuum drying
Dry.
Except formaldehyde catalyst coating by mass percent be 5%-50% except formaldehyde catalyst, 10%-70% adhesive, 0-
2% thickener and water is made, and above-mentioned prescription quality percentage total amount is 100%.
Except formaldehyde catalyst be metal oxide catalyst, noble metal catalyst, one kind in rare-earth metal catalyst or
Several combinations.
In order to which what is be optimal removes formaldehyde performance, except formaldehyde catalyst is nm-class catalyst, granularity is 5-100 nanometers.
Adhesive is Aqueous Adhesives and/or inorganic adhesive, in order to be fixedly secured catalyst, and plays urge to greatest extent
Agent removes formaldehyde performance, the preferred vinyl acetate class adhesive of Aqueous Adhesives, polyacrylic adhesive, water-based polyurethane
Adhesive or neoprene type of latex type adhesive；The preferred Ludox of inorganic adhesive or titanium colloidal sol.
In order to avoid catalyst coat comes off and prevents that catalyst from absorbing the moisture content in excessive air and causes active reduction,
Catalyst fixed bed by mass percent be 10%-70% Aqueous Adhesives, 0.1%-1% thickener, 0-1% defoamer, 0-
5% pigment and water is made, and above-mentioned prescription quality percentage total amount is 100%.
In order to allow catalyst surface to be higher than 800mPas by uniform fold, the viscosity of catalyst fixed bed.
The preferred vinyl acetate class adhesive of above-mentioned Aqueous Adhesives, polyacrylic adhesive, water-based polyurethane gluing
Agent or neoprene type of latex type adhesive, above-mentioned thickener preferred cellulose class thickener, subtract swelling type catalyst or association type catalysis
Agent.
In order to which catalyst coat surface is completely covered, while the performance of catalyst coat is not influenceed again, the catalyst is consolidated
The one side addition weight of given layer is 30-200g/m2。
A kind of to remove formaldehyde filter except formaldehyde coating process using above-mentioned, filter surfaces are provided with except formaldehyde catalyst
Coating, described removing are provided with catalyst fixed bed above formaldehyde catalyst coating.
Described filter is the structure of cellular, tabular, rugosity, one or more combination in corrugated.
The beneficial effects of the invention are as follows：Catalyst fixed bed will be fixed well except formaldehyde catalyst coating, prevent it
Come off, and avoid catalyst exposure and absorb moisture content in atmosphere, reduce the activity of catalyst；While catalyst fixed bed is not
Formaldehyde catalyst coating covering parcel can will be removed, ensure that the effect except formaldehyde.
