Antiseptic wear-resisting freezing adhesion-resisting one coat paint and preparation method thereof

Abstract

The invention provides an antiseptic wear-resisting freezing adhesion-resisting one coat paint which comprises a component A and a component B, wherein the component A comprises the following materials in percentage by weight: 10-40% of isocyanate, 30-75% of amine terminated polyether, 1-15% of fluorine-containing siloxane and 5-25% of anhydrous butylacetate; and the component B comprises the following materials in percentage by weight: 15%-55% of steric hindrance type alkyl secondary amine, 1%-15% of nano freezing adhesion-resisting material, 10%-55% of pigment and filler, 0.5%-2.5% of dispersing agent, 0-2% of thixotropic agent, 0-3% of ultraviolet absorber and 5%-30% of solvent. The antiseptic wear-resisting freezing adhesion-resisting one coat paint provided by the invention is double-component paint comprising a curing agent component and an auxiliary component; and a spraying process is mainly adopted, so that the formed functional coating has the advantages of good antiseptic effect, abradability and freezing adhesion resistance, thus the paint is especially suitable for occasions in which requirements on wear-resistance, corrosion resistance and freezing adhesion resistance are high, such as heavy-duty vehicle coating, wind turbine blades and the like.

Description

A kind of anti-corrosion, wear-resistant, anti-freezing, anti-freeze, sticky bottom and surface all-in-one coating and preparation method thereof technical field The invention relates to the field of coatings, in particular to an anti-corrosion, wear-resistant, anti-freezing, anti-freezing and bottom-surface-integrated coating and a preparation method thereof. Background technique At present, most of the existing domestic anti-corrosion coating systems use primers, intermediate paints, top coats or composite anti-corrosion coating systems of primers and top coats. The main function of the primer is to lay a good foundation on the substrate, which has good adhesion to the substrate and has anti-rust performance; the main function of the intermediate paint is to increase the film thickness, so as to play a more effective shielding effect, and to make the The surface is smooth, which is conducive to topcoat coating; the main function of the topcoat is to prevent harmful corro...

AI Technical Summary

Problems solved by technology

However, the existing coating protection technology for wind turbine blades in China is difficult to meet the requirements of anti-corrosion, wear resistance and anti-icing at the same time.
