Description
Technical Field
The invention relates to a new material and a processing method, in particular to a super-hydrophobic self-cleaning PVC composite material and a preparation method thereof.
Background
The super-hydrophobic material has a plurality of unique surface properties, such as self-cleaning, corrosion prevention, super-hydrophobicity and the like, so that the super-hydrophobic material has wide application scenes in production and life, such as antifogging and antiscaling of glass surfaces, desert water collection, self-cleaning building materials, waterproof and antifouling of textiles, waterproof and antifouling treatment and the like. In recent years, with the increasing attention of super-hydrophobic materials, artificially prepared super-hydrophobic materials are continuously appearing, such as super-hydrophobic coatings, super-hydrophobic films, super-hydrophobic gels, super-hydrophobic fabrics, super-hydrophobic metal surfaces and the like. However, research on superhydrophobicity of commonly used general-purpose plastics (e.g., PP, PE, PVC, etc.) has been rarely reported.
The PVC material has the advantages of high mechanical strength, good heat resistance, low cost, good chemical resistance, difficult corrosion, long service life and the like, and is widely applied to the aspect of building materials. For example, in a PVC drain pipe, impurities in the discharged sewage are easily adhered to the inner wall of the pipe to form dirt, which increases the fluid resistance of the pipe and reduces the sewage discharge capacity.
At present, most methods for improving the hydrophobicity of materials are to spray a super-hydrophobic coating on the surface or carry out simple surface treatment, but the coating is easy to peel off and has short service life; the surface treatment mostly adopts an etching method, and the environmental pollution is relatively large.
The present application was made based on this.

(6) The PVC composite material prepared by the invention has a super-hydrophobic surface which is not easy to damage and is suitable for long-term use.
