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 fire extinguisher and a preparation method thereof. Background technique [0002] Fire extinguisher, also known as fire extinguisher, is a portable fire fighting tool. The fire extinguisher contains chemicals to save the fire police. Fire extinguishers are one of the common fire prevention facilities and are stored in public places or places where fire may occur. Different types of fire extinguishers have different built-in components, and they are designed for different fire alarms. Commonly used fire extinguishers are generally portable or cart type. [0003] The patent application number 200910174865.9 discloses a transparent fire extinguisher bottle. The body of the fire extinguisher bottle is made of transparent high-pressure engineering plastic, which is corrosion-resistant, heat-resistant, UV-resistant, radiation-resistant, light in weight, good in insulatio...
