Abstract

The invention discloses a method for preparing anticorrosive protective paint with polyaniline / attapulgite clay composite particle and an application thereof. The method comprises the following steps: firstly preparing polyaniline / attapulgite clay composite particles through the in-situ method; secondly preparing acrylic acid / methylmethacrylate / butyl methacrylate terpolymer solution; and finally mixing the polyaniline / attapulgite clay composite particles with the terpolymer solution in a certain ratio, and performing ultrasonic stirring to obtain the anticorrosive protective paint. The methoduses the polyaniline / attapulgite clay composite particles as the main raw material to prepare the anticorrosive protective paint; and the paint has good uniformity, adhesivity, coating processing property and corrosion resistance, thus effectively increasing the economic value added of attapulgite clay and effectively saving resources and energy.

Description

technical field [0001] The invention relates to a method and application for preparing an anti-corrosion protective coating by using polyaniline / attapulgite composite particles, and belongs to the manufacturing technology of material protective coating in the field of metal protection. Background technique [0002] Corrosion of metal is a phenomenon in which metal is destroyed by chemical or electrochemical action of environmental medium. Corrosion of metals spreads across various industries and brings huge losses to the national economy. According to the survey and statistics of developed countries in the world, the direct economic loss caused by corrosion accounts for 1-4% of the total output value of the national economy, the annual corroded and rusted steel accounts for about 20% of the output, and about 30% of the equipment is scrapped due to corrosion. In my country, the economic loss caused by metal corrosion is as high as 30 billion yuan per year, accounting for 4% ...
