Problems solved by technology

Defects of solvent-based epoxy resin antirust paint: 1. Poor outdoor weather resistance; 2. Poor low-temperature curing; 3. Release a small amount of toxic and harmful substances, endangering human health and polluting the environment
[0007] Although the existing water-based anti-rust paint can avoid the defects of solvent-based epoxy resin anti-rust paint to a certain extent, there are limitations in stability, acid and alkali resistance and other comprehensive properties, which cannot meet market demand

Abstract

The invention relates to a waterborne epoxy antirust paint and a preparation method. The antirust paint mainly comprises a component A and a component B; the component A comprises the following constituents in percentage by mass: 40-55% of paint paste mixture, 43-58% of epoxy resin emulsion and 1.2-8% of auxiliary II, wherein the total of the constituents aforementioned is 100% by weight; the paint paste mixture comprises the following constituents in percentage by mass: 40-85% of pigments and fillers, 0.3-6% of auxiliary I and the balance of water; and the component B is a curing agent. The preparation method comprises the following steps of: preparing the paint paste mixture according to prescription amounts, and mixing and stirring the paint paste mixture, the epoxy resin emulsion and the auxiliary II according to prescription amounts to obtain the component A; and packaging the component A and the component in a ratio by mass. The waterborne epoxy antirust paint obtained by the prescription disclosed by the invention is excellent in water-resistant, oil-resistant, acid-base-resistant, salt-mist-resistant performances and the like, excellent in anti-rust and anti-corrosion performances, and good in mechanical performances of adhesion force, flexibility, impact resistance and the like.

Description

technical field [0001] The invention relates to the technical field of antirust paint, in particular to a water-based epoxy antirust paint and a preparation method thereof. Background technique [0002] As people pay more and more attention to environmental protection, safe production, etc., as well as awareness of sustainable and healthy development, countries all over the world have higher and higher environmental protection requirements for coatings. The level of VOC content has become a measure of whether a coating is It is the standard of environmental protection paint. Driven by national environmental protection laws and regulations, the development of my country's coatings industry is moving towards the direction of convenient construction, resource saving, health and environmental protection. Safe, non-toxic and efficient water-based coatings are growing rapidly by leaps and bounds. Therefore, promoting the development, production and use of water-based coatings has...
