Problems solved by technology

[0003] Commonly used skeleton materials for polymer products include cord, cord, glass fiber, glass fiber cloth, carbon fiber, carbon fiber cloth, steel wire, etc. These skeleton materials are not only microscopically smooth, but also physically / chemically inert, and have no strong physical properties with the polymer matrix. / Chemical action, the combined action of the two aspects leads to a weak interface between the polymer matrix and the skeleton, and the polymer matrix-skeleton is easy to delaminate under the action of an external force, and the external load cannot be effectively transmitted to the skeleton, resulting in the skeleton being unable to exert reinforcement effect

Abstract

The invention belongs to the technical field of polymer-skeleton adhesion, and relates to a polymer-skeleton interface enhancing agent simulating mussel foot adhesion and a preparing method thereof. The polymer-skeleton interface enhancing agent is prepared from, by mass, 100 parts of polar polymers, 0.05-50 parts of nano filler, 0.01-10 parts of amine compounds, 0.01-10 parts of polyphenols and 0.01-10 parts of polyvalent metal salts. Based on an adhesion mechanism of mussel feet, by replacing expensive dopamine with the cheap and commercial polyphenols, the amine compounds and the polyvalentmetal salts, an adhesion enhancing system of imitative mussel foot muscle protein is constructed, and the polymer-skeleton interface adhesion strength is improved.

Description

technical field [0001] The invention belongs to the technical field of polymer-skeleton bonding, and in particular relates to a polymer-skeleton interface enhancer for imitating mussel foot adhesion and a preparation method thereof. Background technique [0002] The skeleton structure can significantly improve the mechanical and structural stability of polymer products, and can reduce the mechanical relaxation phenomenon (creep and stress relaxation) of polymer products, so that it can be used as structural parts instead of metal structural parts, which is conducive to the lightweight of products. Aerospace, automobile, rail transit and other fields have a wide range of application requirements. [0003] Commonly used skeleton materials for polymer products include cord, cord, glass fiber, glass fiber cloth, carbon fiber, carbon fiber cloth, steel wire, etc. These skeleton materials are not only microscopically smooth, but also physically / chemically inert, and have no strong...
