一种ABC类干粉灭火剂及其制备方法
摘要：
本发明提供一种ABC类干粉灭火剂及其制备方法。本发明提供的ABC类干粉灭火剂粒径为D90为5～20μm，按质量含量计，由包括以下组分的原料混合聚合反应得到：灭火基料60～80％，活性白土0.1～5％，云母0.5～8％，滑石粉0.5～8％，硬脂酸钙0.2～5％，二茂铁0.05～1％，疏水白炭黑1～15％，改性乳液2～15％；所述改性乳液为有机硅改性剂、水、汽油和乳化剂的混合物。本发明以有机硅改性剂、水、汽油和乳化剂的混合物作为改性乳液，使有机硅改性剂分散均匀，在活性白土和二茂铁的催化作用下对灭火基料进行改性处理，与疏水白炭黑和硬脂酸钙共同作用在物料表面形成疏水组分，同时在滑石粉和云母的作用下提高流动性。
摘要（英）：

The invention provides an ABC type dry powder extinguishing agent and a preparation method thereof. With a particle size D90 of 5-20mu m, the ABC dry powder extinguishing agent provided by the invention is prepared by mixing the following raw materials in percentage by mass for a polymerization reaction: 60-80% of extinguishing base material, 0.1-5% of activated clay, 0.5-8% of mica, 0.5-8% of talc powder, 0.2-5% of calcium stearate, 0.05-1% of ferrocene, 1-15% of hydrophobic white carbon black and 2-15% of modified emulsion, wherein the modified emulsion is a mixture of organic silicone modifier, water, gasoline and emulsifier. According to the ABC type dry powder extinguishing agent provided by the invention, the mixture of organic silicone modifier, water, gasoline and emulsifier is adopted as the modified emulsion, thus the organic silicone modifier is dispersed uniformly; under the catalytic action of the activated clay and ferrocene, the extinguishing base material is modified, and a hydrophobic component is formed on the material surface through joint action with the hydrophobic white carbon black and calcium stearate; meanwhile, the fluidity is improved under the actions of the talc powder and the mica.
