AI Technical Summary

Technical Problem

Existing aerosol fire extinguishing agents cannot simultaneously achieve high efficiency, low toxicity, low smoke, and stability in enclosed or semi-enclosed spaces. In particular, they suffer from problems such as unstable storage, highly irritating smoke, and high risk of contamination to precision equipment under wide temperature and humidity conditions.

Method used

A wide-temperature stable system was constructed by using composite stabilizers and gradient coating of double-layer microcapsules. Combined with smoke-suppressing compound and nano-catalyst for complete combustion, and polyethylene glycol was used to assist in smoke elimination, forming a low-smoke control system, thus preparing a low-toxicity and high-efficiency aerosol fire extinguishing agent.

Benefits of technology

It maintains stable storage within a wide temperature and humidity range, starts up quickly, produces low smoke and low irritation, improves fire extinguishing efficiency, and reduces the risk of smoke generation and residual pollution.

Abstract

This invention belongs to the field of aerosol fire extinguishing agent technology, and discloses a low-toxicity, high-efficiency aerosol fire extinguishing agent composition and its preparation method. The composition comprises, by weight, 70-82 parts of a fire extinguishing core component, 7-10 parts of a wide-temperature stabilizing system, 8-16 parts of a low-smoke control system, and 1-3 parts of a binder. The wide-temperature stabilizing system contains a composite stabilizer and a double-layer microcapsule coated on the surface of the core component. The double-layer microcapsule consists of an inner layer of ammonium polyphosphate coating and an outer layer of modified silane coupling agent coating, with a total coating thickness of 5-15 μm. The low-smoke control system contains a smoke suppression component, a combustion completion control component, and an auxiliary smoke elimination component. The method includes the steps of modified raw material preparation, compounding, gradient coating, mixing and granulation, and drying and packaging. This composition combines low toxicity, high efficiency, wide-temperature stability, and low smoke and low irritation.
