NOVELTY - Green and environmentally friendly flame extinguishing agent comprises 50-70 pts. wt. deionized water, 5-15 pts. wt. plant extracts, 5-10 pts. wt. sodium carbonate, 1-5 pts. wt. sodium bicarbonate, 1-5 pts. wt. salt (low sodium type), 1-5 pts. wt. active agent, 5-15 pts. wt. biological polysaccharide, 10-15 pts. wt. potassium chloride, 2-4 pts. wt. magnesium stearate, 2-8 pts. wt. borate, 6-12 pts. wt. ammonium dihydrogen phosphate, 5-15 pts. wt. cyclic phosphate, 0.1-1 pts. wt. graphene oxide and 5-20 pts. wt. anti-freezing agent. USE - Used as green and environmentally friendly flame extinguishing agent. ADVANTAGE - The green and environmentally friendly flame extinguishing agent has deionized water and natural plants as main components, which have zero pollution to the kitchen environment, food materials and air. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing green and environmentally friendly flame extinguishing agent, comprising (i) washing the fresh purslane, placing for 15-26 hours, pulverizing with plant pulverizer to obtain paste, extruding and filtering to obtain filtrate, adding deionized water into the obtained solid material, filtering the filtrate, re-grinding, combining the two filtrates, allowing to stand for 10-15 hours, and filtering to obtain clear yellow green solution, (ii) extracting with proper amount of ethyl acetate, recycling the inorganic phase part as the raw material of the next step, processing other two plant raw materials by the same method, (iii) adding 3-8 L plant extract into 100 L stirring tank, adding 50 L de-ionized water, uniformly stirring at 200-400 revolutions/minute for 30 minutes, adding sodium carbonate, sodium bicarbonate and salt continuously stirring for 1 hours, completely dissolving the material, without obvious particles, adding surfactant and continuously stirring for 30 minutes, where the material liquid is semi-transparent, and (iv) adding biological polysaccharide, potassium chloride, magnesium stearate, borate, ammonium dihydrogen phosphate, cyclic phosphate, graphene oxide and anti-freezing agent, quantifying to obtain the finished product.
