[0054] Example 1
[0055] Prepare 1 kilogram of pyrotechnic aerosol-forming fire extinguishing composition, and add the following components in a paddle mixer: 111 grams of specific surface area is 1500 cm 2 / g of formaldehyde-phenol polycondensate and 19.59 grams of dichloromethane to obtain an 85% suspension. The suspension was prepared in a reactor with a water jacket at 20-25°C, and the rotation speed of the blades in the mixer was 85 rpm. The mixing time is 15 minutes.
[0056] In this suspension, 45 grams of a dispersion of polytetrafluoroethylene particles in butyl phthalate was added, and the ratio of polytetrafluoroethylene to butyl phthalate was 20:25. The dispersion was prepared in a reactor with a water jacket at 20-25°C. The rotation speed of the blades in the mixer was 85 rpm. The mixing time is 10 minutes.
[0057] In the prepared suspension of formaldehyde-phenol polycondensate in dichloromethane and the suspension of polytetrafluoroethylene dispersion of dibutyl p...
