一种井下留存二氧化碳的防灭火材料
摘要：
本发明公开了一种井下留存二氧化碳的防灭火材料，其中A组分占配成水溶液后的比例为7％-25％，B组分占配成水溶液后的比例为5％-8％。A组分的主要作用为吸收二氧化碳，主要由醇胺类组成，其中醇胺类吸收剂占配成水溶液后的比例为7％-25％。B组分主要由水玻璃及表面活性剂组成，其中水玻璃占配成水溶液后的比例为4.5％-7.5％，表面活性剂占配成水溶液后的比例为0.5％。本发明的有益效果是该材料不仅能够留存二氧化碳从而起到防止煤炭自燃的作用，而且有效降低了排放到大气中的二氧化碳的量，减轻了温室气体的排放，对环境有益。
摘要（英）：

The invention discloses a down-hole fire preventing and extinguishing material with a carbon dioxide retaining function. A component A accounts for 7%-25% of the weight of prepared water solution, a component B accounts for 5%-8% of the weight of the prepared water solution, the component A is mainly used for absorbing the carbon dioxide and mainly comprises alcohol amine substances, and an alcohol amine absorbing agent accounts for 7%-25% of the weight of the prepared water solution. The component B mainly comprises water glass and a surface active agent, the water glass accounts for 4.5%-7.5% of the weight of the prepared water solution, and the surface active agent accounts for 0.5% of the weight of the prepared water solution. The material has the advantages that the material can retain the carbon dioxide to prevent spontaneous combustion of coal, the carbon dioxide emitted to the atmosphere can be effectively reduced, emission of greenhouse gas is relieved, and the material is beneficial to environments.
