Abstract
The invention discloses a photocatalyst plate. The photocatalyst plate is characterized in that: the plate is prepared by blending a nanometer titanium dioxide photocatalyst, thermoplastic phenolic resin and a foaming agent; the plate is provided with a plurality of pores; and the plate is in a porous structure similar to the structure of sponge. A producing method of the photocatalyst plate comprises: (1) a step of weighing the raw materials, namely a step of separately weighing 75-92% by weight of the thermoplastic phenolic resin and 3-19% of the nanometer titanium dioxide photocatalyst, blending the weighed thermoplastic phenolic resin and the weighed nanometer titanium dioxide photocatalyst in a twin-screw extruder, granulating, adding the foaming agent, extruding and foaming in a foaming machine to form a plate having a perforated structure, and removing 3-5 mm of the surface layer of the plate so as to expose the pore structure; and (2) a step of surface activation, namely a step of dipping the photocatalyst base plate obtained in the step (1) in a commercially available photocatalyst emulsion for 5 min, taking the base plate out, and airing for 48 h to obtain the photocatalyst plate.
Description
Technical field
The present invention relates to a kind of photocatalyst plate with and production method, belong to photocatalyst technology field.
Background technology
Along with the raising of people's living standard, various upholstery materials, daily-use chemical industry articles for use constantly discharge pollutants to indoor, as the organic volatile in formaldehyde, coating in glued board, the chemical additive in leather etc., the serious harm people's of these pollutents health.Therefore a series of purifying air measure is arisen at the historic moment: charcoal absorption, chemical reagent oxidizes, ozone oxidation, nano photo-catalytic are processed etc.The life cycle of gac is short, easily reach capacity, and the use of chemical reagent and ozone easily causes secondary pollution.Photocatalyst is a kind of nano level metal oxide materials (titanium dioxide is more conventional), and it coats substrate surface, and the dry rear film that forms, under the effect of light, produces strong catalyzed degradation function: toxic and harmful in the air of effectively degrading; Can effectively kill various bacteria, antibiotic rate is up to 99.99%, and the toxin that bacterium or fungi can be discharged decomposes and harmless treatment; Also possesses the function such as deodorizing, anti-soil simultaneously.How to make photocatalyst be applied on sheet material with a problem demanding prompt solution.
Summary of the invention
The present invention is directed to the proposition of above problem, and develop a kind of photocatalyst plate with and production method.
The technical scheme that the present invention takes is as follows:
A kind of photocatalyst plate, is characterized in that: sheet material is by nano-titania photocatalyst, and novolac resin and whipping agent blend are made, and are distributed with porous in sheet material, is the similar spongy structure of porous.
A production method of producing a kind of photocatalyst plate as described in claim l, is characterized in that: comprise the following steps:
(1) taking of raw material
Taking respectively mass percent is the novolac resin of 75-92% and the nano-titania photocatalyst of 3-19%; The nano-titania photocatalyst taking and novolac resin be blend granulation on twin screw extruder, then adds whipping agent, and on foaming machine, extrusion foaming becomes the sheet material of open-celled structure; Remove again 3 to 5 millimeters of sheet material epidermal areas, expose pore structure.
(2) surface activating process
The photocatalyst plate substrate of gained in step (1) is immersed in commercially available photo-catalytic emulsion to 5 minutes, takes out to dry within 48 hours, obtaining photocatalyst plate.
A kind of production method of photocatalyst plate is further comprising the steps of: regeneration and activation technique is in the time that the use of photocatalyst plate exceedes 3 years, surface is covered by the organic substance of dust or decomposition and catalytic efficiency while declining, photocatalyst plate is immersed in in distilled water 5 minutes and takes out to dry within 48 hours, obtain photocatalyst plate.
Beneficial effect of the present invention: owing to having adopted technique scheme, the invention provides that it is simple in structure, be not only convenient to produce, and cost is very cheap is suitable for extensive popularization.
