Abstract

The invention relates to a polymer sulfonate fire retardant, containing a copolymer obtained by polymerization reaction from an unsaturated sodium sulfonate monomer, an unsaturated potassium sulfonate monomer and a vinyl monomer; the vinyl monomer is selected from any one or more of C6-C12 aromatic vinyl compounds, a (methyl) acrylate compound, a vinyl amide compound, a vinyl ether compound or a cyanation vinyl ether compound; the mole ratio of the total of the unsaturated sodium sulfonate monomer and the unsaturated potassium sulfonate monomer to the vinyl monomer in polymer sulfonate is (0.025 to 0.5):1; the mole ratio of the unsaturated sodium sulfonate monomer to the unsaturated potassium sulfonate monomer in the polymer sulfonate is (30:70) to (90:10); a number-average molar mass of the polymer sulfonate is 1000-200000. The invention also relates to a preparation method and application of the polymer sulfonate fire retardant.

Description

technical field [0001] The invention relates to the field of sulfonate flame retardants, in particular to a polymer sulfonate flame retardant and its preparation method and application. Background technique [0002] Polycarbonate (PC) is a thermoplastic engineering plastic with good comprehensive properties. It has good mechanical properties, excellent heat resistance, and electrical resistance. It also has high transparency, high impact strength, and low creep. , Widely used in electronic appliances, industrial machinery parts, medical equipment, automobile industry, construction industry and other fields. Polycarbonate itself has a certain self-extinguishing property, but with the improvement of flame retardant requirements, it is still difficult to meet the flame retardant performance requirements of some application fields, so it is necessary to modify polycarbonate flame retardant. [0003] Flame retardants are a class of functional additives that impart flame retardan...
