Self-healing material

Abstract

The invention discloses a self-healing material which is mainly prepared from a porous material, paraffin, a polymer composite material, dicyclopentadiene liquid and a Grubbs' catalyst, wherein the polymer composite material is prepared from carbon, glass and resin. The porous material fully absorbs the dicyclopentadiene liquid, the porous material containing the dicyclopentadiene liquid is wrapped in the paraffin to be prepared into microcapsules, the microcapsules are doped into the polymer composite material containing the Grubbs' catalyst, and the self-healing material is obtained. The self-healing material has the advantages that cost is low, the manufacturing technology is simple, and the self-healing performance is remarkable.

Description

technical field [0001] The present invention designs building materials, and in particular relates to a self-healing material. Background technique [0002] Existing self-healing materials mainly include three parts: 1. Composite materials, most of which are epoxy polymer composite materials. 2. Repairing agent sealed with microcapsules, which is an adhesive used in the repair of micro-cracks formed on composite materials. The repair compound is a liquid called dicyclopentadiene, or DCPD. The fluid is encapsulated with small blisters that can be diffused throughout the composite. Catalyst In order for polymerization to occur, the repair agent must come into contact with a catalyst. Catalyst has a patented product called Grubb Catalyst for this self-healing material. It is important that the catalyst and repair compound be separated before they can be used to close cracks. When a microcrack forms in a composite material, it spreads across the surface of the material. So...
