Abstract

The invention discloses a throwing type fire extinguisher and a manufacturing method thereof. The throwing type fire extinguisher comprises a fire extinguishing agent and a fire extinguisher bottle for storing the fire extinguishing agent. The throwing type fire extinguisher is characterized in that the fire extinguishing agent comprises the following components: a fluorinated surfactant, potassium carbonate, ammonium sulfate, urea, ammonium polyphosphate, an anionic surfactant, lauryl sodium sulfate and water; the fire extinguisher is a polyvinyl-chloride-resin bottle with self extinguishment. The throwing type fire extinguisher disclosed by the invention has the advantages that due to ingenious utilization of self extinguishment, flame resistance and cold resistance of polyvinyl chloride, normal use can be achieved at the temperature of minus 30 DEG C; the size of impact resistance is proper, breaking can not be finished by hands, the breaking rate is high in throwing, and broken scraps are not splashed and do not hurt persons.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a throwing type fire extinguisher and a preparation method thereof. Background technique [0002] A fire extinguisher, also known as a fire extinguisher, is a portable fire extinguishing tool. Fire extinguishers contain chemicals to put out fires. Fire extinguishers are one of the common fire prevention facilities and are stored in public places or places where fires may occur. Different types of fire extinguishers contain different ingredients and are designed for different fire alarms. Commonly used fire extinguishers are generally portable or cart-type. [0003] The patent application number is 200910174865.9 discloses a transparent fire extinguisher bottle, the fire extinguisher bottle body is made of transparent high-pressure engineering plastics, corrosion resistance, heat resistance, ultraviolet resistance, radiation resistance, light weight, good insulation, an...
