Abstract
The utility model relates to a self-cleaning PVC pipe applied in construction, water supply, electricity and communication fields, which is composed of a PVC (1), a thin layer (2) containing titanium dioxide and made on the inner surface of the PVC (1), a thin layer (3) containing silicon dioxide and made on the outer surface of the PVC (1), as well as a thin layer (4) containing titanium dioxide and made on the surface of the thin layer (3). The utility model has the function of the self-cleaning decontamination and sterilization on the outer surface of the PVC pipe and the inner surface without oil stain under the natural light or sun light.
Description
Technical field:
The present invention relates to a kind of automatically cleaning pvc pipe material, be used for fields such as building, water supply, power supply, communication.
Background technique
The pvc pipe material is widely used in building, water supply, power supply, communication and other various fields.At present, known pvc pipe material easily bond greasy dirt and dust, not only influence external attractive in appearance, and in some application as drainage pipeline the time, also can cause line clogging because of the bonding and the accumulation of greasy dirt.
Summary of the invention:
In order to overcome easily the bond deficiency of greasy dirt and dust of existing P VC tubing, the invention provides a kind of automatically cleaning pvc pipe material.
Automatically cleaning pvc pipe material is formed by PVC (1) with at the thin layer that contains titanium dioxide (4) of the thin layer that contains titanium dioxide (2) for preparing on the internal surface of PVC (1), the thin layer that contains silica (3) that is preparing on the outer surface of PVC (1) and preparation on thin layer (3) surface.
The present invention has under natural light or solar irradiation, and the outer surface of pvc pipe can self-cleaning decontamination, sterilization, and the internal surface function of sticking greasy dirt.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
Embodiment:
Pvc pipe is cleaned up by known method, adopt conventional rubbing method evenly to apply one deck SiO at the outer surface of pvc pipe
2Colloidal sol, and make it dry under 30 ℃～90 ℃ environment, adopt chemical liquid deposition again after the dry cooling, placing pvc pipe with distilled water or deionized water is solvent and the solution that mixes that contains a certain amount of hexafluoro acid titanium ammonium and boric acid, 50 ℃～95 ℃ deposit, obtain uniform Detitanium-ore-type TiO at the inner and outer surface of pvc pipe
2Film promptly obtains having the pvc pipe of self-cleaning function behind the cool drying.SiO
2Colloidal sol can be added in the anhydrous alcohol and fully stirred by a certain amount of ethyl orthosilicate, drips a certain amount of water again and is hydrolyzed, and obtains after fully stirring a period of time; TiO
2Colloidal sol can directly be dissolved in the titanium alkoxide in the anhydrous alcohol and obtaining through hydrolysis.
Claims (1)
1. automatically cleaning pvc pipe material, form by pvc pipe (1), it is characterized in that it also be included in the thin layer that contains titanium dioxide (2) for preparing on the internal surface of PVC (1), at thin layer that contains silica (3) for preparing on the outer surface of PVC (1) and the thin layer that contains titanium dioxide (4) that on thin layer (3) surface, prepares.
