Manufacturing method of carbon foam using waste marble powder

摘要

The present invention relates to a method for producing a carbon foam using waste artificial marble, and more particularly, a method for producing a dough by dissolving waste artificial marble powder and CMC in water (step 1); Treating the dough produced in step 1 with radiation or heat to crosslink the dough (step 2); Drying the cross-linked dough obtained in the step 2 by radiation or heat treatment to prepare a composite material (step 3); And carbonizing the dried composite material in the step 3 (step 4). The present invention also relates to a method for producing carbon foam using waste artificial marble. By manufacturing the carbon foam using the waste artificial marble powder according to the present invention, it is possible to recycle or reuse abandoned artificial marble powder to increase the resource efficiency and to minimize the environmental pollution. In addition, But it is a simple and easy way to manufacture and provide carbon foam.
