Abstract

The invention discloses anticorrosive paint with green and environmental protection property and excellent corrosion resistance, namely polyaniline-chopped glass fiber-phenolic resin paint. The paint is composed of the following raw materials (by weight): 20-40 parts of polyaniline-chopped glass fiber composite material, 40-70 parts of phenolic resin, 2-10 parts of filler, 0.05-1.5 parts of a dispersant, 0.05-1.5 parts of an organosilicon leveling agent, 0.2-1 part of an anti-sag agent Dapro BEZ 75, 10-60 parts of a solvent and 3-8 parts of a polyamide curing agent. According to the method, polyaniline and an inorganic material chopped glass fiber modified composite material is firstly prepared; and then, the composite material is added into phenolic resin to prepare the phenolic resin paint. Meanwhile, the influence of the composite material on corrosion resistance of the phenolic resin paint is studied. The paint of the invention has heat stability, dispersity, mechanical property and corrosion resistance, is pollution-free to human body and the nature, and is a new environment-friendly paint.

Description

[0001] Technical field: [0002] The invention relates to a new type of polymer material in the field of metal anticorrosion technology, specifically a polyaniline-chopped glass fiber-phenolic resin coating and a preparation method thereof. Background technique [0003] Metal materials have a long history and a wide range of applications. In modern life, you can always see the shadow of metal materials. Metal materials have become the most important and commonly used engineering materials, and they are inseparable from the construction of bridges, buildings, ships and other national economy. Because metal materials are severely damaged by corrosion in the external environment, they lose use value. The harm of metal corrosion has caused great losses to the national economic construction and people's daily life, which are generally divided into direct and indirect losses. The direct loss includes the cost of various anti-corrosion measures adopted in the destruction of materials, e...
