Abstract

The invention discloses a general modified epoxy antirust paint with high performances and high solids and a preparation method thereof. The paint comprises a component A and a component B, wherein the component A comprises 10-20 parts of an E44 epoxy resin, 10-20 parts of an NPPN-631 epoxy resin, 5-15 parts of a terpene resin, 4-18 parts of a cumarone resin, 0.1-1.0 parts of a BYK antifoaming agent, 0.1-1.0 part of an HX leveling agent, 0.1-1.5 parts of a rheological assistant, 5-20 parts of active silica, 10-20 parts of a mixed solvent and 10-30 parts of a pigment-filler; and the component B comprises 10-40 parts of cardanol modified amine and 0.5-3 parts of a modified silane coupling agent. The antirust paint of the invention has the advantages of compact coating, low viscosity, good compatibility and fast curing of a curing agent, high tough strength and strong adhesion of the coating, coating number reduction during the thick slurry curing, construction efficiency improvement, construction cost reduction, and anticorrosion life prolongation.

Description

technical field [0001] The invention relates to a paint technology, in particular to a high-performance, high-solid general-purpose modified epoxy antirust paint and a preparation method thereof. Background technique [0002] Corrosion is an objective law of nature. Corrosion causes metal damage every year worldwide, causing economic losses of 700 billion US dollars, accounting for 2 to 4% of domestic GDP, while my country's loss of 500 billion yuan accounts for 4% of GDP. There are many kinds of anti-corrosion technology, among which anti-corrosion coating has the characteristics of simple construction, wide adaptability, low cost, and can be used together with other anti-corrosion measures, and is generally favored by people. Among anti-corrosion coatings, epoxy coatings are one of the most widely used coating varieties. Epoxy coatings have excellent adhesion, mechanical strength and corrosion resistance, as well as good alkali resistance, water resistance, and insulation...
