The invention relates to a preparation method of a flame retardant acrylic resin. The flame retardant acrylic resin is prepared by the following materials in percentage by weight and the preparation method comprises the following steps of: adding acrylic monomers, 20 to 30% of deionized water and 1 to 3% of emulsifier into a reaction system, heating up to 70 to 90 DEG C, dripping 0.8 to 1.2% of initiator with dripping time of 0.5-1.5h, and insulating and reacting for 0.5 to 3 h, and obtaining the acrylic resin; and adding bentonite dispersion liquid with solid content of the acrylic resin of 10 to 20% and a phosphorus based flame retardant with the solid content of the acrylic resin of 10 to 30%, mixing for 30 to 60 min under conditions that the pH value is 7 and shearing and mixing speeds are 400 to 1600rpm, and obtaining the flame retardant acrylic resin. The flame retardant acrylic resin has good fire resistance and cheap price and can meet requirements of flame retardant leather products with low cost in the market. |
