Abstract

The invention discloses a preparation method for a self-repairing coating material and application thereof. The coating material comprises a material of a repairing layer located at an inner layer and the material of a surface layer located at an outer layer; urea-formaldehyde resin coated epoxy resin microcapsule (EP-UF microcapsule) is added into the repairing layer so as to provide an epoxy resin (EP) repairing agent; and the repairing agent repairs damages through the action with a curing agent in the surface layer. The self-repairing coating has a self-repairing function, the advantages of large adhesion force to a matrix, high surface hardness, good flame retardancy, excellent surface decorativeness and corrosion resistance, etc., and the characteristics of simple and convenient molding process, low technical requirements and good decorativeness and self-repairability, and is applicable to surface coating of a variety of resin-based composite plate materials.

Description

technical field [0001] The invention relates to the field of preparation of coating materials, in particular to a preparation method and application of a self-repairing coating material. Background technique [0002] As the outer protective and decorative material of the product, the coating will inevitably be damaged by rubbing, scratching, scratching, etc. during the use of the product. Most of the damage cannot be repaired in time, which greatly reduces its protective and decorative effect on the product. If the damage of the coating material can be automatically repaired, it is bound to be able to effectively improve the protection ability and safety reliability of the coating. Contents of the invention [0003] The invention provides a preparation method and application of a self-repairing coating material, which solves the problems existing in the prior art. The prepared coating has a self-repairing function, and also has large substrate adhesion, high surface It ha...
