Definitions
- the present invention relates to the field of fire extinguishing technology, and more particularly to an aerosol fire extinguishing composition containing a saccharide and a saccharide derivative.
- Aerosol fire extinguishing technology has been recognized and widely used as one of the most attractive alternatives to halon in recent years.
- the aerosol fire extinguishing agent releases a large amount of heat while releasing the aerosol after the combustion reaction, so that the temperature of the fire extinguishing device is high, and on the one hand, the excessive temperature may cause burns to the operator, and on the other hand, it may be sprayed. After the release, a secondary fire is caused.
- the physical cooling method and the chemical cooling method are usually employed. The physical cooling method is to cool the front end of the pyrotechnic agent in the fire extinguishing device by adding a cooling system, but this easily leads to the device structure.
- the chemical cooling method is to provide a chemical cooling layer in the spraying direction of the pyrotechnic agent.
- the existing chemical coolant affects the fire extinguishing performance of the pyrotechnic agent, so that the pyrotechnic agent does not easily penetrate the fire plume and directly reaches the root of the fire source.
- most of them will decompose a certain amount of gas particles that are harmful to the human body, which is not conducive to environmental protection.
- the present invention provides a novel fire extinguishing composition containing a saccharide and a saccharide derivative.
- a fire extinguishing composition containing a saccharide and a saccharide derivative which comprises a saccharide derivative, a saccharide substance and an auxiliary fire extinguishing agent, the mass percentages thereof being respectively:
- the fire extinguishing composition is a pyrotechnic agent as a heat source and a power source, and is burned by using a pyrotechnic agent
- the high temperature causes it to be decomposed or reacted by heat, and the fire-extinguishing substance is sprayed out together with the pyrotechnic agent to achieve the purpose of extinguishing the fire.
- the saccharide derivative is one or more selected from the group consisting of sodium gluconate, potassium gluconate, zinc gluconate, calcium gluconate, magnesium gluconate, copper gluconate, ferrous gluconate or manganese gluconate.
- the saccharide substance is one or more of dextrin, glucose, chitosan, starch or fructose.
- the auxiliary fire extinguishing agent in the fire extinguishing composition containing a saccharide and a saccharide derivative of the present invention is an organic salt.
- the organic salt is sodium oxalate, potassium oxalate, potassium citrate, sodium citrate, potassium tartrate, sodium tartrate, potassium hydrogen tartrate, sodium hydrogen tartrate, potassium dihydrogen tartrate, sodium potassium tartrate, potassium acetate, sodium acetate
- ammonium acetate, hexamethylenetetramine or sodium methoxide is sodium oxalate, potassium oxalate, potassium citrate, sodium citrate, potassium tartrate, sodium tartrate, potassium hydrogen tartrate, sodium hydrogen tartrate, potassium dihydrogen tartrate, sodium potassium tartrate, potassium acetate, sodium acetate
- ammonium acetate, hexamethylenetetramine or sodium methoxide is ammonium acetate, hexamethylenetetramine or sodium methoxide.
- the fire extinguishing composition of the present invention further comprises a performance additive in a mass percentage of from 2% to 18%.
- the performance additive is one or more of magnesium stearate, zinc stearate, acetal gum, hydroxypropylmethylcellulose, sodium carboxymethylcellulose or a phenolic resin.
- the components of the fire extinguishing composition of the present invention and the mass percentage thereof are:
- Carbohydrate derivatives 35 % - 55 %
- the fire extinguishing composition of the present invention mainly comprises a sugar derivative and a saccharide substance, the saccharide substance is a carbohydrate, is easily decomposed by heat, and the decomposition product is CO, water, 0 2, etc., is non-toxic and harmless, so the spray
- the product is free from pollution to the environment, and the metal particles in the saccharide derivative can be combined with the radicals in the flame combustion reaction to cut off the combustion reaction chain, thereby exhibiting the flame suppression effect of the metal particles and not affecting the environment, thereby improving the entire Fire extinguishing performance of fire extinguishing compositions.
- the auxiliary fire extinguishing agent containing an organic salt in the fire extinguishing composition of the present invention can generate a large amount of gas by thermal decomposition, increase the overall gas pressure of the hot aerosol, increase the spray intensity of the aerosol, and facilitate the passage of the aerosol through the fire plume. Cut off the fire source and effectively control the fire source.
- the invention optimizes the proportion of each component, so that the overall fire extinguishing performance of the fire extinguishing composition is high, and The effective utilization of each component is high.
- the fire extinguishing composition of the present invention has stable performance and is easy to store for a long time.
- the fire extinguishing composition comprises a sugar derivative, a saccharide substance, an auxiliary fire extinguishing agent and a performance additive, and the mass percentage thereof is: 30% ⁇ 60%, preferably 35% ⁇ 55 %, of the sugar derivative, and the sugar substance 10 % ⁇ 40%, preferably 15% ⁇ 35%, auxiliary fire extinguishing agent 10% -30%, preferably 12% - 24%, performance additive 2% ⁇ 18%, preferably 2% ⁇ 10%; among which sugar derivatives can be selected Or one or more selected from the group consisting of sodium gluconate, potassium gluconate, zinc gluconate, calcium gluconate, magnesium gluconate, copper gluconate, ferrous gluconate or manganese gluconate; the saccharide may be selected from the group consisting of dextrin, One or more of glucose, chitosan, starch or fructose; the auxiliary fire extinguishing agent is an organic salt, specifically sodium oxalate,
- the specific fire extinguishing mechanism is: the fire extinguishing composition can be decomposed and released at a high temperature to release a fire extinguishing substance, which can pass through a radical or a chain combustion reaction, and one or more of OH?
- the reaction is carried out to cut off the chain combustion reaction, and the oxygen partial pressure can be reduced by physical action to suppress the flame, or physical and chemical inhibition can be simultaneously achieved to achieve the fire extinguishing effect, and at the same time, synergistic effect with the pyrotechnic agent is produced. , further improving the fire extinguishing performance of the fire extinguishing agent and greatly shortening the effective fire extinguishing time.
- the gluconate salt, the saccharide substance and the auxiliary fire extinguishing agent and the performance additive in the above examples are selected to be 100 g, and according to the ratio in the following Table 1, the granules can be prepared into a regular solid piece by a process such as mixing granulation and tableting.
- a fire extinguishing device containing 100g of K-type hot aerosol generating agent, according to BS6165: 2002 "Specification for small disposable fire extinguishers of the aerosol type" under the same conditions and prior art fire extinguishing agent (S type fire extinguishing 100g, K-type fire extinguishing agent 100g) 93# gasoline fire test comparison, the results are shown in Table 1.
