一种新型煤炭阻燃添加剂及其阻燃机理

New coal fired retardant and fire retardant mechanism

煤是一种天然高聚物,按照高聚物阻燃设计的概念设计出一种新型煤炭阻燃添加剂,介绍了该阻燃添加剂的性能及其阻燃机理。该阻燃添加剂具有促进形成焦化炭层和阻断自由基链式反应的功能,具有明显的阻燃、隔热、隔气、保水和优异的粘附煤体的特性。实验证明该阻燃剂对煤炭的阻燃性能十分有效。

Coal is a natural high polymer. With the conception of the high polymer retardant theory, a new coal fired retardant was designed. The paper introduced the features and fire retardant mechanism of the coal fired retardant. The coal fire retardant has abilities to promote the formation of carbonized layer and cut the reaction of free chain. The coal fire retardent has obvious features of fire retarding, heat isolation, air isolation, moisture maintaining and excellent adhesive power. The results from laboratories showed that the coal fire retardant features were effective.
