Problems solved by technology

[0003] The present invention aims at various problems existing in the actual use of the existing polypropylene plastic foaming materials, such as low fire flammability, long self-extinguishing time after leaving the fire, and molten drips that easily cause secondary combustion during the combustion process. These have buried hidden dangers for the occurrence of fire and the expansion of fire hazards. To provide a new type of flame retardant material and its preparation method

Embodiment 1

[0023] Mix 100 parts of polypropylene, 3 parts of maleic anhydride grafted polypropylene, 0.5 parts of MD-NA-28, 8 parts of HDC103 and 10 parts of compound flame retardant through a high-mixer, and mix them in a screw extruder Plasticized and melted, mixed with butane injected in the middle of the screw extruder, and then extruded and foamed to obtain a flame-retardant material with flame-retardant properties. The weight ratio of octabromoether and antimony trioxide in the composite flame retardant is 2:1.

Embodiment 2

[0025] Mix 100 parts of polypropylene, 3 parts of maleic anhydride grafted polypropylene, 0.5 parts of MD-NA-28, 8 parts of HDC103 and 5 parts of compound flame retardant through a high-mixer, and mix them in a screw extruder Plasticized, melted and extruded, and then foamed through a dipping tank filled with pentane to obtain a flame-retardant material with flame-retardant properties. The weight ratio of octabromoether to antimony trioxide in the composite flame retardant is 3:1.

Abstract

The invention relates to a new-type inflaming retarding material and a preparation method thereof. The inflaming retarding material comprises the following raw materials in parts by weight: 100 parts of polypropylene, 5-16 parts of modifier, 5-10 parts of compound flame retardant. The new-type inflaming retarding material has better fire resistance, can effectively lower the probability of occurrence of fire disasters, reduce the damages caused by fire disaster compared with other polypropylene plastic foam materials, and can prepare the inflaming retarding materials with different inflaming retarding performances through controlling the content of the compound flame retardant at the same foaming multiplying power.

Description

technical field [0001] The invention relates to a flame-retardant material and a preparation method thereof, in particular to a novel flame-retardant material and a preparation method thereof. Background technique [0002] At present, the existing EPP (Expanded polyproplene): polypropylene plastic foaming materials are all controlled by the expansion rate to control their flame retardancy, and they are all imported from abroad. There are many problems in these materials in the actual use process, such as small fire flammability, long self-extinguishing time from the fire, and molten drips that are easy to cause secondary combustion during the combustion process. And the expansion of fire hazards has buried hidden dangers. High price and easy burning characteristics limit the use of EPP materials. Contents of the invention [0003] The present invention aims at various problems existing in the actual use of the existing polypropylene plastic foaming materials, such as low...
