Preparation method of nano-composite gel foam inhibitor for inhibiting spontaneous combustion of coal

The invention provides a preparation method of a nano composite gel foam inhibitor for inhibiting spontaneous combustion of coal. The preparation method comprises the following steps: uniformly mixing a gel inhibitor grafted with an antioxidant, a nano material and a foaming agent; the gel inhibitor grafted with the antioxidant is composite gel prepared by graft polymerization of the antioxidant and gel inhibitor raw materials under the action of a cross-linking agent and an initiator. By means of the method, the nano-composite gel foam stopping agent which is economical, environmentally friendly, long-acting, high in performance and convenient to use is prepared. 本发明提供一种抑制煤自燃的纳米复合凝胶泡沫阻化剂的制备方法，包括：混合均匀的接枝抗氧化剂的凝胶阻化剂、纳米材料、发泡剂；接枝抗氧化剂的凝胶阻化剂为由抗氧化剂、凝胶阻化剂原料在交联剂与引发剂作用下接枝聚合制成的复合凝胶。通过本发明的方法，制备得到经济、环保、长效高性能、使用方便的纳米复合凝胶泡沫阻化剂。
