Waterborne acrylic modified epoxy ester emulsion anticorrosive coating

Abstract

The invention discloses waterborne acrylic modified epoxy ester emulsion anticorrosive coating. The waterborne acrylic modified epoxy ester emulsion anticorrosive coating comprises a main material andauxiliary materials. The main material is waterborne acrylic modified epoxy ester, and defoaming agents, dispersing agents, titanium dioxide, precipitated barium sulfate, antirust pigment, driers, co-solvents, neutralizers and deionized water are mixed with one another to obtain the auxiliary materials. The waterborne acrylic modified epoxy ester emulsion anticorrosive coating has the advantagesthat modified epoxy ester which is the waterborne acrylic modified epoxy ester made from bisphenol A type epoxy resin and n-octanoic acid by means of mixing is used as the main material for preparingthe waterborne acrylic modified epoxy ester emulsion anticorrosive coating, epoxy ester is stably dispersed in water, the stability of molecules in the waterborne acrylic modified epoxy ester emulsionanticorrosive coating can be improved, accordingly, the water resistance, the acid resistance and the alkali resistance of the waterborne acrylic modified epoxy ester emulsion anticorrosive coating can be improved, and the waterborne acrylic modified epoxy ester emulsion anticorrosive coating is high in storage stability and smearing and drying speed; dispersion kettles are separately washed by deionized water by three times in preparation procedures, wash water is added into blending kettles to be used as a backing material, accordingly, sufficient fatty acid double bonds in the epoxy estercan be guaranteed, oxidative polymerization can be facilitated, raw materials can be saved, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the field of water-based paint, in particular to a water-based acrylic modified epoxy ester emulsion anticorrosion paint. Background technique [0002] With the continuous improvement of people's awareness of environmental protection and the increasingly stringent environmental regulations, water-based coatings have attracted more and more attention. The reason why people pay attention to water-based coatings is that they have the advantages of low combustion, low odor, low toxicity, and low pollution. Especially in recent years, the increasingly serious environmental pollution has prompted countries to formulate environmental protection regulations one after another, and the emission of organic compounds in traditional solvent coatings is increasingly restricted. Various types of machinery, tools, instruments, automobiles, mechanical and electrical products, metal products, machine parts, building materials, ships, iron tower...

Problems solved by technology

[0003] The object of the present invention is to provide a kind of water-based acrylic modified epoxy ester emulsion anticorrosion coating, by using modified epoxy ester to be the water-based acrylic modified epoxy ester that is made by mixing bisphenol A type epoxy resin and n-octanoic acid It is used as the main material for making coatings, so that epoxy esters can be stably dispersed in water, and the stability of the internal molecules of the coatings can be improved, thereby improving the water resistance, acid resistance and alkali resistance of the coatings, with strong storage stability and fast application and drying speed. Solve the problem that the water-based coatings currently on the market have poor anti-corrosion effects during use, and the problem that the surface solution of the coating generates bubbles in rainy weather
