Abstract

The invention discloses nanometer solvent-free epoxy antirust paint and a preparation method thereof. The nanometer solvent-free epoxy antirust paint comprises the following raw material components in parts by weight: component A: 20-40 parts of E-44 epoxy resin, 5-15 parts of active diluent, 10-20 parts of zinc phosphate, 5-20 parts of mica powder, 10-20 parts of nanometer alumina, 10-20 parts of ferric oxide powder and 5-10 parts of aluminum triphosphate; component B: alicyclic amine or anacardol serving as a curing agent. The weight ratio of the component A to the component B is (6-8): 1. The nanometer solvent-free epoxy antirust paint disclosed by the invention is good in antirust property, environment-friendly, free of VOC emission, not harsh in construction conditions and low in requirements on base material, and the paint can be thickly coated once; the nanometer solvent-free epoxy antirust paint can be widely applied to a variety of fields, for example, bridge, guardrail steel structure, building material, machinery, etc.

Description

technical field [0001] The invention relates to an anti-corrosion coating, which belongs to the technical field of chemical coatings, in particular to a nano-solvent-free epoxy anti-rust paint and a preparation method thereof. Background technique [0002] Solvent-free epoxy liquid anti-corrosion paint / anti-corrosion coating is a high solids, room temperature curing (hardening) solvent-free epoxy anti-corrosion coating.
