Embodiment Construction

[0025] The technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings and specific embodiments. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] Such as Figure 1-3 As shown, the self-healing coating material of the present invention includes an inner repair layer material and an outer surface layer material. The repair layer material is added with urea-formaldehyde resin coated epoxy resin microcapsules, and the surface layer material is added with a curing agent. The preparation and application of materials and surface materials include the following steps:

[0027] Step A, preparing epoxy resin microcapsules (EP-UF microcapsules): First, in a three-necked flask, dissolve 50 parts of urea in 90-100 parts of formaldehyde solution, and adjust the pH of the solution with triethanolamine = 8.0~10.0. React at ~80℃ for 30~40min to obtain vis...

Abstract

The invention discloses a preparation method and application of a self-repairing coating material. The coating material includes an inner repairing layer material and an outer layer material, and urea-formaldehyde resin is added to the repairing layer to coat epoxy resin microcapsules (EP ‑UF microcapsules) to provide an epoxy (EP) repair agent that repairs damage by interacting with the curing agent in the surface layer. In addition to the self-healing function, the self-healing coating also has the advantages of large substrate adhesion, high surface hardness, good flame retardancy, excellent surface decoration and corrosion resistance, and has the advantages of simple molding process, low technical requirements, decorative It is suitable for the surface coating of various resin-based composite panels due to its good properties of safety and self-healing.

Description

Technical field [0001] The invention relates to the field of preparation of coating materials, in particular to a preparation method and application of self-repairing coating materials. 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, thus greatly reducing its protective and decorative effects on the product. If the damage of the coating material can be automatically repaired, it is bound to be able to effectively improve the protective ability and safety and reliability of the coating. Summary of the invention [0003] The invention provides a preparation method and application of a self-healing coating material, which solves the problems existing in the prior art. The prepared coating has a self-healing function, and also has high substrate adhesion, high surface hardness and res...
