Abstract

The invention discloses a flame-retardant polyacrylate emulsion and a preparation method thereof. The flame-retardant polyacrylate emulsion consists of 100 parts of polyacrylate emulsion and 5-35 parts of flame retardant by weight parts, wherein the polyacrylate emulsion consists of ethylhexyl acrylate, butyl acrylate, methyl methacrylate, methacrylic acid, crylic acid, functional monomer, reaction emulsifier, emulsifier OP, ammonium persulfate and deionized water; the flame retardant consists of carbonized catalyst, carbonizer and expanding agent. The preparation method of the flame-retardant polyacrylate emulsion includes: utilizing the combined process of pre-emulsifying and seeding polymerizing and adding expansion flame retardant. The flame-retardant polyacrylate emulsion prepared by the preparation method has excellent flame retardancy, adhesivity, filming ability and stability and excellent waterproofness, and can be widely used in the industries of adhesives and coatings and the like.

Description

technical field [0001] The invention relates to a flame-retardant polyacrylate latex and a preparation method thereof, which mainly solves the flame-retardant problem of polyacrylate latex, relates to the formula and process of polyacrylate latex polymerization, the composition, proportion and dosage of flame retardants, etc. content. Background technique [0002] Polyacrylate latex is the product of emulsion polymerization of acrylate or methacrylate and other vinyl ester monomers. Currently the most widely used are (meth)acrylate copolymer emulsion, vinyl acetate / (meth)acrylate copolymer emulsion, styrene / (meth)acrylate copolymer emulsion. The emulsion polymerization process generally includes batch emulsion polymerization, semi-continuous emulsion polymerization, continuous emulsion polymerization, pre-emulsification process, seed emulsion polymerization, etc. Because acrylate copolymer emulsions overcome the shortcomings of oily copolymers that are flammable, explosive...
