Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a high-adhesion and high-strength flame-retardant water-based coating. Background technique [0002] Coatings that use water as a dispersion medium are called water-based coatings, including water-soluble coatings, water-dilutable coatings, and water-dispersible coatings. At present, the adhesion and strength of water-based coatings on the market are not high, and the mechanical properties and flame retardancy are not strong; the introduction of fluoride ions into acrylates, so that the products have excellent weather resistance, water resistance, mechanical properties and other advantages is the current research hotspot How to use this new material to develop a new type of coating that can overcome the shortcomings of water-based coatings has become the focus of current research. Contents of the invention [0003] Based on the technical problems existing in the b...
