Embodiment 1

[0036] A phosphorus-based synergistic flame retardant, prepared by the following method:

[0037] Weigh magnesium chloride, ammonium chloride, trisodium phosphate, dispersant, and antioxidant according to the weight ratio, mix them and add them to the reaction kettle, heat up to 100°C, react at constant temperature for 2 hours, cool down to room temperature, and discharge to the washing tank for further processing Washing, dehydration by a centrifuge to remove moisture, and drying in a cyclone dryer to remove remaining moisture. The drying temperature is 180°C to obtain the product polyphosphate.

[0038] The dosage ratio is: 10% magnesium chloride; 30% ammonium chloride; 59% trisodium phosphate; 0.5% dispersant; 0.5% antioxidant.

Embodiment 2

Abstract

The invention belongs to the technical field of phosphorus-containing synergistic flame retardants and discloses a phosphorus synergistic flame retardant and a manufacturing method and application thereof. The phosphorus synergistic flame retardant is prepared by using the following components in mass percent: 40 to 55 percent of halide salt, 45 to 60 percent of phosphate, 0.1 to 1 percent of dispersing agent and 0.1 to 1 percent of antioxidant, wherein the total mass percent is 100 percent. When the phosphorus synergistic flame retardant disclosed by the invention and a halogen-antimony flame-retardant system coexist, a dual synergistic effect is achieved, and the phosphorus synergistic flame retardant and halogen in the halogen-antimony flame-retardant system form another halogen-phosphorus flame-retardant synergistic system to enable the flame-retardant efficiency of the original halogen-antimony flame-retardant system to be superposed. During combustion, bromine-phosphorus and halogen-antimony flame-retardant systems undergo polymerization or hybrid coupling reaction, such that solid-phase and gas-phase systems are enabled to simultaneously have bromine-phosphorus and halogen-antimony molecule dual flame-retardant superposed synergistic effects, the flame-retardant effect is enhanced and a good flame-retardant and smoke-inhibiting effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of phosphorus-containing synergistic flame retardants, in particular to a phosphorus-based synergistic flame retardant and its manufacturing method and application. Background technique [0002] Although there is a certain amount of production of both halogen-free intumescent flame retardants and halogen-free environmentally friendly flame-retardant plastics in my country, they have not yet formed a scale and a wide range of applications, and their proportion in flame-retardant products is relatively small. The development of flame retardants and environmentally friendly flame retardant plastics in China should be positioned at halogen-free, environmentally friendly, high-efficiency, and industrializable varieties with good comprehensive performance, increase the research and development technology of new environmentally friendly flame retardant materials, and further formulate product standards (including ma...
