Preparation Technology of Polyurethane Foam Concrete

Preparation Technology Abstract. Polyurethane foam concrete is prepared by solventless two-component polyurethane materials, cement, KC-15 composite blowing agents and calcium stearate foam stabilizer. It discussed the synthesis mechanism and studied the preparation process for the preparation of polyurethane foam concrete in the paper. The effects of materials addition order for foams quality and molded concrete are analyzed in detail. The key factor affecting foams quality is the additional order of polyurethane aggregates and foams. Two cement systems are suitable for polyurethane film forming and foams stable. Post addition of polyurethane aggregates can significantly decrease the bubble bursting. The preparation method referred a reference for the preparation of polyurethane foam concrete.
