Abstract

The invention discloses a solvent-free epoxy self-leveling heavy anticorrosive terrace coating, which is composed of the following raw materials (by weight): 40-50% of epoxy resin, 5-10% of a diluent, 30-40% of a filling material, 5-10% of pigment, 3-10% of a curing agent and 1-2% of an auxiliary agent. Total percentage of the above components is 100%. According to the invention, modified liquid epoxy resin, a nonactive epoxy diluent and a cashew nut shell oil modified amine epoxy resin solvent-free curing agent are used as raw materials to obtain the terrace coating. The coating has good resistance to chemical corrosion, and the problem that existing solvent-free epoxy terrace coatings have strong smell and are poisonous is solved.

Description

technical field [0001] The invention belongs to the technical field of building materials and relates to a solvent-free epoxy self-leveling heavy-duty anti-corrosion floor paint. Background technique [0002] Epoxy resins are widely used in adhesives, potting materials, coatings and other industries due to their excellent adhesion and resistance to chemical media corrosion. At present, the epoxy resin used in the coating industry accounts for about half of its total output, and a variety of high-performance coatings are produced. Epoxy resins are used in anti-corrosion coatings with liquid coatings accounting for the largest share, but conventional solvent-based epoxy resin coatings mostly use aromatic hydrocarbons, esters, ketones, etc. as solvents. Most of these solvents are toxic and cause more environmental pollution after volatilization. Governments all over the world have successively imposed restrictions on the content of volatile organic compounds. In view of this,...
