Embodiment Construction

[0025] Further description will be made below in conjunction with specific embodiments.

[0026] This embodiment provides first a kind of low-temperature S-type fire extinguishing agent, which mainly consists of a mixture comprising the following components (weight ratio):

[0027] 45% to 75% of oxidizing agent, 15% to 25% of reducing agent, 3% to 10% of binder, and 7% to 10% of additive; wherein, the oxidizing agent is a mixture of strontium nitrate and nitroguanidine, and the reducing agent is The high-nitrogen energy-containing compound, the binder is a resin compound, and the additive is one or more of organic acid potassium salt and magnesium carbonate compound.

[0028] The particle size of the mixture constituting the above-mentioned fire extinguishing agent product is 40-100um, which has better diffuseness.

[0029] Among the 45%-75% of the oxidant, strontium nitrate accounts for 35%-60%, and nitroguanidine accounts for 10%-15%.

[0030] In the 15%-25% reducing agent...

Abstract

The invention relates to a low-temperature S-shaped fire extinguishing agent and a preparation method thereof. The low-temperature S-shaped fire extinguishing agent is composed of a mixture comprisingthe following components in percentage by weight: 45%-75% of an oxidizing agent, 15%-25% of a reducing agent, 3%-10% of an adhesive and 7%-10% of an additive. The oxidizing agent is a mixture of strontium nitrate and nitroguanidine, the reducing agent is a high-nitrogen energetic compound, the adhesive is a resin compound, and the additive is one or more of organic acid potassium salt and magnesium carbonate compounds. Kinetic energy can be provided for releasing the fire extinguishing agent composition, the diffusivity of an aerosol product is improved, potassium ions in the additive are combined, the fire extinguishing performance can be further enhanced, and flame suppression and cooling are achieved.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to a low-temperature S-type fire extinguishing agent and a preparation method thereof. Background technique [0002] Aerosol fire extinguishing agent has become a research hotspot at home and abroad because of its high fire extinguishing efficiency, no damage to the ozone layer and low production cost. The combustion of aerosol fire extinguishing agent can produce a large amount of gas / solid phase components. Because of its chemical inhibition, physical isolation and cooling effect, it can quickly extinguish fires and is suitable for applications in many fields such as building fire protection, communications, energy, transportation, marine, military, etc. . [0003] After more than ten years of development, domestic aerosol fire extinguishing agents have achieved a good market in the field of building fire protection. At present, the method of total flooding is ...
