Self-repairing material and preparation method and application thereof

Abstract

The invention discloses a self-repairing material and a preparation method and application thereof. The self-repairing material comprises lacunose teflon film, holes in the teflon film are filled withperfluocarbon polymer, plasma processing is carried out on the teflon film for modification, and the perfluocarbon polymer accounts for more than 0.1 wt% of mass proportion of the teflon film. The preparation method comprises the steps of washing, drying after washing, the plasma processing for modification and vacuum impregnation, wherein the teflon film is washed with a washing agent for ultrasonic cleaning; the modified teflon film is impregnated in a melting liquid of the perfluocarbon polymer for impregnation; a solvent is used for removing residual perfluocarbon polymer remaining on thesurface of the teflon film, and storage at an indoor temperature is performed to obtain the self-repairing material. The contact angle between the self-repairing material and a liquid is greater than98 degrees, that is, the surface of the material is below 25 Mn / m, and the self-repairing material has antifouling and water-proof functions and has properties of good adhesion, easy coating, corrosion resistance, convenient processing, aging resistance, long-acting slow release, and environment protection.

Description

technical field [0001] The invention relates to the field of environmental protection materials, in particular to a self-repairing material and its preparation method and application. Background technique [0002] So far, the anti-biological pollution is mainly through the coating of tin or copper-containing coatings, so that these toxic metals slowly release toxicity, so as to achieve the purpose of killing biological pollution; however, the toxic substances contained in these coatings will eventually follow the biological chain into the human body. At present, although silicone coatings are widely used, they still have certain limitations, such as poor antifouling effect on algae and short service life. Therefore, they cannot meet the needs of users for environmental protection and service life. Contents of the invention [0003] In view of this, the present invention provides a self-repairing material, which has strong anti-fouling and waterproof functions, and also ha...
