Abstract

The invention relates to a method for preparing a flame-retardant core-shell type waterborne acrylate resin coating. The method comprises the following steps of adding water, an emulsifier and acrylic acid, raising the temperature to 40 DEG C, stirring for 30 minutes, adding a monomer A, emulsifying for 15-45 minutes, raising the temperature to 70 DEG C, starting to introduce recirculation water, raising the temperature to 80 DEG C, reacting for 2 hours, dropwise adding an initiator for 2-4 hours, and reacting for 1-2 hours; adding manganese amino acid, stirring and reacting for 1-4 hours at 80 DEG C, adding a metal salt to adjust the pH value to be 4, adding manganese acetate, stirring and reacting for 1-2 hours at 60 DEG C to obtain a core layer emulsion; simultaneously dropwise adding a monomer B and an initiator into the core layer emulsion for 1-3 hours, stirring and reacting for 3 hours at 70-85 DEG C, adding a crosslinking agent, reacting for 1-3 hours at 70-90 DEG C, cooling to 40 DEG C, adding molybdenum di(2-ethylhexyl)phosphorodithioate and an emulsifier, reacting for 40 minutes, adding the material B, stirring and reacting for 1-3 hours at 65-85 DEG C and adding aqueous ammonia to adjust the pH value to be 7-8 to obtain the flame-retardant core-shell type waterborne acrylate resin coating. By virtue of the preparation method, the flame resistance of the acrylate resin can be greatly improved and the shortcoming of yellowing of a traditional acrylate resin film can also be improved.

Description

[0001] This application is a divisional application of the Chinese invention patent application with the application number 2014103589573 submitted on July 27, 2014, and the title of the invention is a method for preparing a flame-retardant core-shell water-based acrylic resin coating. technical field [0002] The invention relates to a preparation method of a water-based acrylic resin, in particular to a preparation method of a core-shell type water-based acrylic resin coating for buildings and furniture. Background technique [0003] Compared with traditional solvent-based coatings, water-based coatings have the advantages of low price, safe use, saving resources and energy, and reducing environmental pollution and public nuisance, so it has become the main direction of the current development of the coatings industry. water-based acrylic Ester resin coatings are the fastest-growing and most diverse non-polluting coatings among water-based coatings. [0004] The largest ma...
