Polyurethane(PUR) foam was filled by corn stalk broken powder. The effects of content and particle size of corn stalk broken powder on density and compressive strength of PUR foam were studied, and the heat conduction performance of PUR foam was researched. The results showed that the performance of corn stalk broken powder filled PUR foam board was equivalent with unfilled PUR foam board, but the cost was relatively cheap. The corn stalk broken powder filled polyurethane foam board could be used as anti-seepage insulation material for canals.
