Abstract

The invention discloses a water-based paint prepared from waste slag and a preparation method thereof, belonging to the field of paints in fine chemical engineering. The water-based paint comprises 20-45 parts of silicone-acrylic emulsion, 5.0-15.0 parts of epoxy modified acrylate emulsion, 5.0-20.0 parts of water-based polyurethane, 5.8-9.0 parts of aid, 3.5-10 parts of pigment and 30-40 parts of waste mineral particle powder. The waste mineral left by metallurgy is recovered and made into powder or granules; the epoxy modified acrylate emulsion and silicone-acrylic emulsion are utilized to compositely modify the paint, thereby overcoming the defect in the common water-based paint; the obtained paint has the advantages of no toxicity, no solvent and no pollution; and the metallurgical mineral waste is recycled, and the high-quality paint formula is obtained. The paint can be used as a high-grade building external wall stone-like lacquer paint and other external wall paints.

Description

technical field [0001] The invention belongs to the field of fine chemical industry, and more specifically relates to a water-based coating containing waste slag and a preparation method thereof. The coating material is suitable for exterior wall coatings such as anti-stone and real lacquer coatings for building exterior walls, and can also be used as an anti-corrosion bright topcoat , such as outdoor anti-corrosion paint, automotive chassis, automotive topcoat repair, interior decoration and other surface coatings. Background technique [0002] With the deteriorating environment and the gradual depletion of resources in our country, the recycling of waste metallurgical minerals is not only in line with the current sustainable development route, but also greatly reduces environmental pollution (a large amount of waste slag falls on lakes, farmland, and dust floats, which is harmful to surrounding people or Food and beverages bring considerable harm; typical problems such as ...
