Abstract

The invention discloses a three-dimensional structure attapulgite / graphene / polyaniline composite anti-corrosion filler, which comprises a one-dimensional structure attapulgite / polyaniline composite material and a two-dimensional structure attapulgite / polyaniline composite material. Polybasic acid is added into a system, so that the effect of a doping agent is achieved, and the effect of a cross-linking agent is also achieved. Aniline monomers adsorbed at the attapulgite surface and the graphite oxide layer take an in-situ oxidation polymerization reaction, and meanwhile, a graphite oxide sheet layer is supported open through a soft chemistry effect; then, polyaniline gel is generated through the effect of the cross-linking agent; meanwhile, one-dimensional attapulgite and two-dimensional graphene are connected, so that three-dimensional cross-linking structure attapulgite / graphene / polyaniline composite gel is formed; after freezing and drying, the three-dimensional cross-linking structure of the composite material can be still maintained; after the composite gel is added into paint, the anti-corrosion performance of a coating can be greatly improved.

Description

technical field

[0001] The invention belongs to the field of anticorrosion fillers for coatings, and in particular relates to an attapulgite / graphene / polyaniline composite anticorrosion material and a preparation method thereof. Background technique

[0002] Metal corrosion has caused serious losses to the national economy and serious harm to social life. In order to prevent metal corrosion, anti-corrosion paint is usually coated on the metal surface to isolate the corrosive medium from contacting the metal surface, so as to achieve anti-corrosion effect. Anti-corrosion fillers are the key components in anti-corrosion coatings. However, at present, most anti-corrosion fillers are metals or metal compounds, which contain heavy metals such as hexavalent chromium and lead. There are problems such as high cost, short anti-corrosion period and heavy metal pollution. subject to strict restrictions. Polyaniline has become a new generation of friendly and efficient anti-corrosion ...
