Problems solved by technology

In the preparation of polyacrylate emulsion, by adding fluorine-containing acrylic acid monomer, the synthetic polymer coating has good water repellency and thermal stability and excellent washing resistance; however, acrylate polymers and most polymers Similar to the material, it is a flammable material. When heated in the air, it will decompose and generate some volatile combustibles. When the temperature of the system and the concentration of combustibles are too high, it will burn

Abstract

The present invention discloses a preparation method for an organic-phosphorus-modified fluorine-containing polyacrylate flame retarding finishing agent. The method is implemented in accordance with the following steps of: step 1, mixing butyl acrylate, methyl methacrylate, a fluorine-containing monomer, a phosphorus-containing monomer, a reactive emulsifier, and deionized water to prepare pre-emulsion; step 2, weighing ammonium persulfate and deionized water respectively, and dissolving the ammonium persulfate into the deionized water to prepare an aqueous solution of ammonium persulfate; and step 3, mounting a reaction apparatus, adding the pre-emulsion prepared in the step 1 and the aqueous solution of ammonium persulfate prepared in the step 2 into the reaction apparatus, and preparing the organic phosphorus-modified fluorine-containing polyacrylate flame retarding finishing agent after reaction. The preparation method for organic phosphorus-modified fluorine-containing polyacrylate flame retarding finishing agent provided by the invention adopts the organic phosphorus-modified polyacrylate material for the flammable property, and endows the material with durable, low-smoking, non-toxic, and environmentally friendly flame retardant properties.

Description

technical field [0001] The invention belongs to the technical field of preparation methods of flame-retardant finishing agents, and in particular relates to a preparation method of organophosphorus-modified fluorine-containing polyacrylate flame-retardant finishing agents. Background technique [0002] In modern production and life, polymer materials are widely used and have become important materials for economic construction and scientific and technological development. However, these materials are usually combustible or combustible materials, which need to be endowed with flame retardancy by adding flame retardants, otherwise it is easy to bury fire hazards. In addition, polymer materials will also produce toxic gases when they burn, such as: toluene will be produced when polystyrene is burned, and hydrogen chloride will be produced when polyvinyl chloride is burned, which will easily cause harm to the surrounding environment and people's lives. [0003] Acrylate polymer...
