Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a filtering device for preparing a flame retardant coating emulsion. Background Art

[0002] Flame retardant emulsion is an emulsion technology based on the copolymerization of vinyl chloride and ethylene. Since vinyl chloride-ethylene copolymer has a high limiting oxygen index, it means that the polymer itself is a flame retardant material. At the same time, due to the high content of chlorine in the emulsion, the chlorine element can capture hydrogen bond free radicals generated during the combustion process in the gas phase environment, thereby reducing the generation of combustible gases.

[0003] When preparing the flame retardant emulsion, acrylate monomer, 2-hydroxyethyl methacrylate phosphate, emulsifier and water are mixed, and then pre-emulsified by high-speed stirring for 15 minutes to 30 minutes. Zirconium phosphate is added thereto, and pre-emulsification is continued for 10 minutes to 20 minutes to obtain a pre-emulsion; zirconium phosphate modified polyacrylate emulsion is prepared by semi-continuous pre-emulsification emulsion polymerization; the pH of the emulsion is adjusted to 8 to 9, and a nitrogen-containing phenolic resin aqueous solution is added. After uniform mixing, a zirconium phosphate synergistic nitrogen-containing phenolic resin flame retardant water-based polyacrylate emulsion is obtained.

[0004] After the flame retardant emulsion is produced by the reactor, the finished product needs to be filtered to filter out the impurities in the finished product. Nowadays, most reactors are equipped with filters, but the filters are fixed in the innermost part of the reactor. Especially for some large reactors, operators need to use ladders to climb into the reactor to clean the filters, which is quite troublesome. Utility Model Content
