Embodiment 1
[0027] The water-based solid-micro system fire extinguishing agent for extinguishing the combustion flame of lithium batteries comprises the following components in parts by weight:
[0028] In order, add 2 parts of dispersant, 0.2 part of dispersing aid, 0.2 part of polyamide wax conditioner, 0.1 part of bentonite conditioner, 0.5 part of thixotropic thickener, and 0.03 part of preservative in deionized water, and stir well After 10-30 minutes, add 10 parts of raw material powder and tris-HCl solution to adjust the pH to 8.0-8.5. Add enough deionized water, 100 parts in total, and continue stirring for 10-30 minutes to obtain a water-based solid-micro system fire extinguishing agent. The raw material powder is composed of magnesium iron aluminum silicate mineral (vermiculite) powder, magnesium aluminum silicate clay mineral (palygorskite) powder, chemically modified graphite powder, potassium sodium calcium magnesium iron alumina silicon Salt (montmorillonite) powder and wra...
