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
Design building material of the present invention, particularly relates to a kind of self-healing material.
Background technology
Existing self-healing material, mainly comprise three parts: 1, matrix material, wherein most of material is all epoxy polymer matrix material, and polymer composites belongs to advanced material, is made up of carbon, glass or Kai Er pressgang fiber and resin; 2, micro-encapsulated healant is used, a kind of tackiness agent used when this is the microfracture formed on repair composite material.Healant is a kind of liquid being called dicyclopentadiene or DCPD.This liquid capsule is wrapped in, and vesicle is equipped with in the inside, can be spread to each place of matrix material.Catalyzer, in order to polymerization reaction take place, healant must and catalyst exposure.Catalyzer has a kind of patented product, and Ge Labu catalyzer by name, can be used for this self-healing material.Catalyzer and healant are being used for must separating before healed fracture, and this point is very important.When matrix material being formed microfracture, it can come in material surface diffusion.Therefore, this crack can make microcapsules rupture, thus discharges healant.Healant will trickle along crack, so just inevitably encounter Ge Labu catalyzer, thus start polymerization process.Crack finally can be glued together by this process, and through test, the matrix material of self-healing can recover 75% of its green strength.
The main drawback of current self-healing material is exactly that complex structure, manufacturing cost are high, not easily popularizes.
Summary of the invention
