Problems solved by technology

At present, the known PVC pipes are easy to stick to oil and dust, which not only affects the external appearance, but also in some application fields such as sewer pipes, the pipes will be blocked due to the adhesion and accumulation of oil.

Embodiment Construction

[0011] see figure 1 , the PVC pipe 1 is cleaned according to the known method, and a layer of titanium dioxide sol is evenly coated on the inner and outer surfaces of the PVC pipe 1 by a conventional coating method, and dried at an environment of 30° C. to 90° C. Then use the chemical liquid phase deposition method, place the PVC pipe in a solution that uses distilled water or deionized water as a solvent and contains a certain amount of ammonium titanium hexafluorate and boric acid, and deposit it at 50°C to 95°C. Uniform anatase-type titanium dioxide films 2 and 3 are obtained on the inner and outer surfaces of the PVC pipe 1. After cooling and drying, an oil-resistant PVC pipe is obtained. 4 is a protective layer to prevent damage to the outer titanium dioxide film 3 during transportation. The thickness of the titanium dioxide films 2 and 3 is generally 0.02-0.1 mm.

[0012] Although the embodiments of the present invention have been shown and described, those skilled in t...

Abstract

The invention relates to an oil-stain-resistant PVC pipe which is used in the fields such as building, water supply, power supply and communication. The inner surface and the outer surface of the PVC pipe are respectively coated with a titanium dioxide thin film. Each titanium dioxide thin film is an anatase type titanium dioxide thin film, and the thickness of each titanium dioxide thin film is 0.02-0.1mm. The oil-stain-resistant PVC pipe has the advantages that under the natural light or sunlight condition, dirt on the outer surface of the PVC pipe can be removed automatically so that the outer surface of the PVC pipe is cleaned, sterilization of the outer surface of the PVC pipe is achieved automatically, no oil can adhere to the surface of the PVC pipe, the mechanical strength and the adhesive force of the thin films are improved, cracks are avoided, ultraviolet light and moisture are prevented from penetrating through the PVC pipe, and the service life of the thin films is prolonged; meanwhile, the titanium dioxide thin films on the surfaces of the PVC pipe have the good covering capacity, the titanium dioxide thin films are similar to white lead, and the white lead can become black but the titanium dioxide thin films do not become black; the PVC pipe also has the durability the same as that of zinc white, the PVC pipe is not prone to chemical changes, the appearance of the PVC pipe is snow-white all the time, and the good visual effect is achieved.

Description

technical field [0001] The invention relates to an oil-stain-resistant PVC pipe, which is used in the fields of construction, water supply, power supply, communication and the like. Background technique [0002] PVC pipes are widely used in construction, water supply, power supply, communication and many other fields. At present, the known PVC pipes are easy to adhere to oil and dust, which not only affects the appearance of the pipe, but also causes pipeline blockage due to the adhesion and accumulation of oil in some application fields such as sewer pipes. Contents of the invention [0003] In order to overcome the disadvantage that the existing PVC pipes are easy to stick to oil and dust, the present invention provides an oil-proof PVC pipe, which can decompose surface oil by itself and prevent blockage. [0004] The technical solution adopted by the present invention to solve the technical problem is: an oil-stain-resistant PVC pipe, including a PVC pipe, the inner an...
