Abstract
The utility model relates to a photocatalytic board for air purification, which is characterized in that plank is formed by blending nano titanium dioxide photocatalyst and thermoplastic resin, a plurality of pores are formed in the plank, and the plank is in the shape similar to sponge integrally. The photocatalytic board adopts a multi-hoe and opening structure, thereby increasing the contact area of the air and material, and ensuring higher photocatalysis efficiency; the nano titanium dioxide photocatalyst is combined in plastic base material, and the feature that the titanium dioxide is separated from the interface of the base material is adopted, so as to ensure that the titanium dioxide is exposed on the surface of the base material and can be simultaneously bonded on the surface firmly, thereby prolonging the active life and service life of the material; the concentration of photocatalyst on the surface is further increased by activating the photocatalytic board through photocatalytic emulsion, and the activity is increased; moreover, after a period of time of use, the photocatalytic board can be dunk in the photocatalytic emulsion for activation, thereby ensuring that the photocatalytic board can be used repeatedly, and saving cost.
Description
[technical field]
This utility model relates to a kind of air cleaning photocatalyst plate.
[background technology]
Raising along with people's living standard, various upholstery materials, daily-use chemical industry articles for use constantly discharge pollutants to indoor, as: the formaldehyde in the plywood, the organic volatile in the coating, the chemical addition agent in the leather or the like, the harm people's that these pollutant are serious health.Therefore a series of air cleaning measure is arisen at the historic moment: activated carbon adsorption, chemical reagent oxidizes, ozone oxidation, nano photo-catalytic are handled or the like.The life cycle of active carbon is lacked, is reached capacity easily, and the use of chemical reagent and ozone causes secondary pollution easily.And nano photo-catalytic is looked at as the parent that a kind of safe, simple and effective technology more and more is subjected to people.
The nano photocatalyst product of Cai Yonging mainly is divided into two kinds in the market: photo-catalytic emulsion and photocatalyst plate.Photo-catalytic emulsion is easy to use, but it is slow to take effect, and is covered by dust easily and loses purification function; Normal optical catalyst plate be with photocatalytic spray at metal or nonmetal planar surface, reach the purpose of dispeling noxious substance by contacting with air, its surface area is less, photocatalyst is bonding stable inadequately, breaks away from and loses efficacy from plate surface easily.
[summary of the invention]
At the problems referred to above, a purpose of the present utility model provides that a kind of surface area is big, the higher photocatalyst plate of photocatalysis efficiency; Another purpose provides big, the difficult photocatalyst plate that comes off from plate surface of a kind of surface light catalyst concentration.
For achieving the above object, technical solution adopted in the utility model is as follows:
A kind of air cleaning photocatalyst plate has porous in the sheet material, be the similar spongiosis of porous.
Sheet material is made up of nano titanium oxide photocatalyst and thermoplastic resin.
Described thermoplastic resin is polystyrene or polyethylene or polypropylene or polymethyl methacrylate.
During making, at first with nano titanium oxide photocatalyst and thermoplastic resin, extrusion foaming becomes to have the sheet material of open-celled structure on foaming machine, is immersed in the photo-catalytic emulsion after removing epidermal area, dries after ultrasonic 5 minutes promptly to obtain the photocatalyst plate; This photocatalyst plate can soak photo-catalytic emulsion once more after use a period of time and activate.
Some apertures are arranged in this utility model sheet material, and integral body is similar spongiosis, and its surface area increases greatly, makes the gas that sees through wherein that the bigger stop catalysis time be arranged in sheet material, has improved its photocatalysis efficiency; Sheet material adopts thermoplastic resin and nano titanium oxide to form, the nano titanium oxide photocatalyst is compounded in the plastic basis material, utilize the isolating characteristics of titanium dioxide and substrate interface, make titanium dioxide be exposed to substrate surface, simultaneously again can be firm be bonded in the surface, make its surface light catalyst concentration increase the activity and the service life that have increased material; Utilize photo-catalytic emulsion activation light catalyst plate, further increased surface light catalyst concentration, increased activity.

[specific embodiment]
As shown in Figure 1, a kind of air cleaning photocatalyst plate, sheet material is made by nano titanium oxide photocatalyst and thermoplastic resin, and some apertures are arranged in the sheet material, and integral body is similar spongiosis.During making, at first get mass fraction and be 70～98% thermoplastic resin and 2～20% nano titanium oxide photocatalyst, the blend pelletize on double screw extruder with nano titanium oxide photocatalyst and thermoplastic resin, add foaming agent then, extrusion foaming becomes to have the sheet material of open-celled structure on foaming machine, remove the sheet material epidermis, expose pore structure; The photocatalyst plate substrate is immersed in the commercially available photo-catalytic emulsion, ultrasonic 5 minutes, takes out to dry promptly obtaining the photocatalyst plate.
Shown in accompanying drawing 2 and 3, the photocatalyst plate is porous and open-celled structure, can increase the contact area of air and material, makes its photocatalysis efficiency higher; The nano titanium oxide photocatalyst is compounded in the plastic basis material, utilize the isolating characteristics of titanium dioxide and substrate interface, make titanium dioxide be exposed to substrate surface, simultaneously again can be firm be bonded in the surface, the activity and the service life of material have been increased, utilize photo-catalytic emulsion activation light catalyst plate, further increased surface light catalyst concentration, increased activity; And this utility model can soak photo-catalytic emulsion once more after use a period of time and activate, and makes it reusable, has saved cost.
