The invention belongs to the technical field of material preparation, and particularly relates to a coal pile flame-retardant composite covering agent and a preparation method thereof. The coal pile flame-retardant composite covering agent comprises the following components in parts by weight: 5-8 parts of a binder, 5-7 parts of a thickening agent, 0.2-0.6 part of a surfactant, 2-5 parts of a stopping agent and 75-90 parts of water. The prepared flame-retardant composite covering agent for the coal pile can effectively prevent oxygen from entering a coal body, can effectively absorb free radicals generated in a coal oxidation process, and further prevents a low-temperature oxidation reaction in the coal pile from occurring. 本发明属于材料制备技术领域，具体涉及一种煤堆阻燃复合覆盖剂及其制备方法。所述煤堆阻燃复合覆盖剂，包括以下重量份计的组分：粘结剂5～8份、增稠剂5～7份、表面活性剂0.2～0.6份、阻化剂2～5份、水75～90份。本发明制得的煤堆阻燃复合覆盖剂能够有效隔绝氧气进入煤体内部，同时还能够有效吸收煤氧化过程中产生的自由基，进一步阻止煤堆内部低温氧化反应的发生。
