Abstract

The invention discloses self-repairing resin, coating and film as well as a preparation method and application of the film, and belongs to the technical field of coatings. The self-repairing resin comprises the following components, in parts by weight: 30-50 parts of an oligomer, 3-20 parts of a curing agent and 20-70 parts of a solvent, wherein the oligomer is a double-layer carbon long-chain structure containing a curable functional group. According to method provided by the invention, the double-layer carbon-carbon long-chain structural oligomer containing the curable functional group is added, so that the wear-resistant, elastic and self-repairing product can be obtained.

Description

technical field [0001] The invention relates to a technology in the field of coatings, in particular to a self-repairing resin, a coating, a film and a film preparation method and application. Background technique [0002] Polymer matrix composites with self-healing function is an important research in the field of coatings. However, the current self-healing coatings have the following problems: it is necessary to add repair materials to the body and then release the repair materials for repair, or it needs a specific environment (light, heating, pH value) for repair. The former has complicated preparation process and limited number of repairs. The life is short, and the latter has a relatively large limit on the scope of use of the coating. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention proposes a preparation method and application of a self-repairing resin, coating, film and film. By adding a double-...
