The invention discloses high-performance waterborne double-component
epoxy resin with relatively high
solid content and a preparation method. The high-performance waterborne double-component
epoxy resin is prepared from a component A and a component B, wherein the component A is prepared from the following components: waterborne
epoxy emulsion, modified
zinc phosphate, kaolin, ultrafine precipitated
barium sulfate, permanent violet
slurry, a dispersant A and a dispersant B, a de-
foaming agent A and a de-
foaming agent B, a rheological auxiliary agent A and a rheological auxiliary agent B, a flatting agent and de-ionized water; the component B is prepared from the following components: an epoxy curing agent, de-ionized water and matte
slurry; the component A and the component B are mixed according to the ratio of 2.7 to 1. The product disclosed by the invention has a
strong binding force with a matrix and has relatively high
corrosion prevention performance; the product has a relativelygood
adhesive force and certain decoration performance on a
machining surface of a
metal part; relatively thick
coating film thickness can be formed in one step; a
coating film on the product is transparent and matte; the high-performance waterborne double-component epoxy resin can be blended according to different color requirements and integrates
corrosion resistance, mechanical properties and adecoration function into a whole; the production cost is reduced and the emission of VOC (Volatile Organic Compounds) is reduced.
