Abstract

The experiment is to extract lignin from straw as the basic material, then to develop cheap resin. By mechanical foaming, we are to research lignin-based epoxy compounds with commercial foaming agent or sodium lauryl sulfate and the foam stabilizing effect under the experimental condition that adding or not coagulant. The study shows that the actual amount of foam can change the strength and weight of foam concrete to some extent. The results of experimental show that the lignin-based epoxy resins prepared by inexpensive straw can be applied YX-M-8-type foaming agent and the modification of sodium dodecyl sulfate in order to improve the utilization of straw, with great social and economic benefits.
