Problems solved by technology

The introduction of sulfonate can endow polycarbonate with catalytic flame retardancy, and the organic sulfonate such as potassium diphenylsulfonesulfonate (KSS) which has been industrially applied has good catalytic flame retardancy for polycarbonate materials, but It is a small molecule flame retardant and the polycarbonate material matrix lacks physical entanglement and is easy to precipitate, so the application limitations are large

Abstract

The invention relates to the technical field of macromolecules, in particular to an anti-dripping polymer sulfonate flame retardant and a preparation method thereof, comprising the following steps: 1) according to weight parts, emulsifier, unsaturated sulfonate, unsaturated The monomer and part of the deionized water are mixed, heated and stirred until uniform, the mixture A is obtained and kept warm, and set aside; 2) the initiator is added to the mixture A, and heated and stirred for free radical reaction to obtain a polymer sulfonate copolymer emulsion, Standby; 3) Add another part of deionized water and polytetrafluoroethylene emulsion into the polymer sulfonate copolymer emulsion, heat up and stir to obtain mixture B, and set aside; 4) Add coagulant to mixture B and stir evenly After heating and reacting, the obtained precipitated product is washed, dried and pulverized to obtain an anti-dripping polymer sulfonate flame retardant. The anti-dripping polymer sulfonate flame retardant of the invention has both durable flame retardancy and anti-dripping properties.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to an anti-dripping polymer sulfonate flame retardant and a preparation method thereof. Background technique [0002] Thermoplastic materials have the advantages of being lightweight, easy to manufacture and industrialized production. They are used in all aspects of our daily production and life, and have brought great impetus to human development. However, thermoplastic materials are easy to burn, soften and deform when heated, and even drip. In the production process, flame retardants need to be added to make them have a wider scope of application. At present, the research and application of flame retardant modification of plastic products have proved that adding flame retardants can delay combustion and reduce the intensity of combustion. However, during the burning process of plastic products, in addition to burning themselves, other combustibles will be dripped and ignited, ca...
