Wear-resistant and scratch-resistant modified alloy and preparation method thereof

Abstract

The invention discloses a wear-resistant and scratch-resistant modified alloy. The added doped polypyrrole is conductive; when used as an anti-corrosion material to protect metal, the doped polypyrrole always reacts partially with the surface metal first, so that the surface metal is corroded and purified. The self-corrosion potential is generally reduced; the molybdic acid functional group is used as an anti-corrosion functional group; when contacting with a metal material, the molybdic acid functional group may be separated from a polypyrrole molecular chain more quickly and react with the metal, so that the metal surface is protected and passivated; and the sulfosalicylic acid doped copolymer with large organic groups is embedded between copolymer molecular chains due to large-size counter ions, so that the extension degree of the polymer chains can be increased, and the chain spacing can be increased; the anticorrosive paint provided by the invention has strong cohesiveness with abase material, and is not easy to fall off; the PC / PET alloy has excellent wear resistance, scratch resistance and heat resistance while having respective excellent properties of PC and PET, and has the advantages of favorable processability, high strength, favorable dimensional stability and small thickness deviation.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a wear-resistant and scratch-resistant modified alloy and a preparation method thereof. Background technique [0002] In recent years, polyaniline, as a new type of conductive polymer material, has attracted more and more attention. Its synthesis process is simple, no pollution to the environment, low cost, and has stable thermodynamic and chemical properties, making it widely used in various fields. In particular, its excellent anti-corrosion performance makes it widely used in the field of anti-corrosion. However, the weak adhesion and insoluble properties of its paint film have greatly restricted its application. If the excellent chemical corrosion resistance of polyaniline is combined with the excellent adhesion and mechanical properties of epoxy resin to prepare blended coatings, this will greatly improve the anti-corrosion ability of epoxy resin coatings, and al...

Problems solved by technology

However, since PC is an amorphous polymer, PET is a crystalline polymer, and PC / PET is a typical amorphous / crystalline blend system, the compatibility of the two is poor, resulting in poor toughness and low strength, and the surface of the product The wear resistance and scratch resistance are poor, which affects its application in some fields
