Problems solved by technology

Traditional solvent-based acrylic paints will release a large amount of volatile organic compounds during the film formation process, causing pollution to the environment
However, there are still many deficiencies in water-based acrylic coatings, such as low hardness of the coating film, poor wear resistance, and unsatisfactory flame retardancy, etc., which hinder its development.

Abstract

The invention discloses a high-flame-retardancy paint which is prepared from a water-based acrylate emulsion, a water-based polyurethane resin, aluminasol, an epoxy resin, polydimethylsiloxane, zinc oxide, hollow glass microspheres, nano zirconium oxide, montmorillonite, nano silicon dioxide, a film forming aid, a defoaming agent, a leveling agent, a wetting agent, a flame retardant and water. The flame retardant is formed by mixing boron oxide, dimethyl methyl phosphonate, phosphorus pentoxide, tri(2-chloropropyl) phosphate, guanylurea phosphate, ammonium polyphosphate, pentaerythritol, melamine and hexamethyl disiloxane. The high-flame-retardancy paint has the advantages of favorable water resistance, favorable wear resistance, excellent flame retardancy and long service life.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a high flame retardant coating. Background technique [0002] Acrylic paint has high hardness, excellent gloss and chemical resistance after film formation, and low cost. It is widely used in the automotive, construction and furniture industries. Traditional solvent-based acrylic coatings will release a large amount of volatile organic compounds during the film formation process, causing pollution to the environment. However, water-based acrylic coatings still have many shortcomings, such as low film hardness, poor wear resistance, and unsatisfactory flame retardancy, which hinder its development. Summary of the invention [0003] Based on the technical problems existing in the background art, the present invention proposes a highly flame-retardant coating, which has good water resistance and abrasion resistance, excellent flame-retardant performance, and long service life. [0004] T...
