Embodiment 1

[0056] Raw material formula (weight%): polyamide 66: 75%, decabromodiphenylethane 5%, expanded graphite 15%, cuprous iodide: 1%, N,N'-bis-(3-(3,5 -Di-tert-butyl-4-hydroxyphenyl)propionyl)hexamethylenediamine 0.5%, silicone powder: 0.5%, nano silicon dioxide 3%.

[0057] Preparation method: Dry the granular polyamide raw material at 90°C for 2 hours, then mix it with decabromodiphenylethane in a mixer for 20 minutes (conditions: normal temperature, stirring speed 60rpm), and then add Expanded graphite, nano-silica, silicone powder, N,N'-bis-(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyl)hexamethylenediamine, cuprous iodide. Mix in a mixer for 30 minutes (conditions: normal temperature, speed 60 rpm). Then the mixed material is mixed and extruded by a twin-screw extruder. After the extruded material is water-cooled and drawn, it is pelletized by a pelletizer and then sieved, dehydrated, and dried. The drying temperature is 100 ° C. The drying time was 1 hour. Obtain the flam...

Abstract

The invention relates to the field of fire fighting, in particular to a composition for a flame-retardant floating cover, a flame-retardant floating cover material and a preparation method of the flame-retardant floating cover material. The composition for the flame-retardant floating cover contains polyamide and a flame retardant, the flame retardant comprises a first component and a second component, the first component is selected from expanded graphite, and the second component is selected from at least one of bis (hexachlorocyclopentadiene) cyclooctane, decabromodiphenyl ethane, brominated polystyrene, antimony trioxide, aluminum hydroxide and magnesium hydroxide; the weight ratio of the first component to the second component is 1: (0.1-5). The composition for the flame-retardant floating cover can play a role in reducing the volatilization rate of the liquid level of an oil product, the composition is thrown in when a fire accident occurs, the flame intensity can be reduced, and the purpose of rapidly extinguishing fire is achieved.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to a composition for a flame-retardant floating cover, a material for a flame-retardant floating cover and a preparation method thereof. Background technique [0002] Petrochemical enterprises need to use storage tanks to store a large amount of crude oil, intermediate materials and refined oil products, and also collect a certain amount of oily wastewater discharged during the production process in wastewater pools or storage tanks. The types of storage tanks currently used include inner floating roof tanks, outer floating roof tanks and vaulted roof tanks. The floating roof tank has less volatile organic compounds (VOCs) emissions due to the liquid surface floating cover and edge soft seal, and the other part is the vaulted roof tank. The respiration generated by the rise and fall of the liquid level will discharge VOCs to the outside of the storage tank, causing environmental poll...
