Abstract

The invention discloses a highly-flame-retardant modified acrylate coating. The raw materials for preparing the coating comprise the following ingredients: 65-80 parts of phosphate ester modified acrylic emulsion, 5-10 parts of polysiloxane, 3-10 parts of waterborne polyurethane emulsion, 2-6 parts of resorcinol bis(diphenyl) phosphate, 0.5-1.8 parts of tri-isopropylphenyl phosphate, 10-30 parts of nanometer aluminum hydroxide, 15-32 parts of titanium dioxide, 5-20 parts of nano-silica, 19-35 parts of ammonium polyphosphate, 5-10 parts of dipentaerythritol, 3-10 parts of beta-cyclodextrin, 3-8 parts of an organic solvent, 3-5 parts of a film-forming additive, 2-5 parts of an auxiliary, and 30-60 parts of water. The highly-flame-retardant modified acrylate coating disclosed by the invention is good in flame retardancy, high in heat resistance, high in strength, and long in service life.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a highly flame-retardant modified acrylate coating. Background technique [0002] Acrylic emulsion is usually a product obtained by emulsion polymerization of acrylate monomers or methacrylic monomers and monomers containing vinyl esters. Acrylate polymer emulsion has been widely used in architectural coatings, anti-corrosion coatings, decorative coatings, etc. because of its excellent UV aging resistance, film-forming properties, environmental protection and pollution-free, etc., and has become a research hotspot. However, polyacrylate is a flammable polymer, which has brought major safety hazards to people's lives. Therefore, people put forward higher requirements for the flame retardancy of such materials. The current acrylic coatings have poor flame retardancy and cannot meet the requirements of the society, and further research and development are needed. Contents of th...
