泡沫塑料轻质耐火板研制成功以泡沫塑料为芯材的墙体是墙体材料改革的一种新趋势，近年来在我国发展较为迅速，有的以聚氨酯泡沫为芯材，外加钢板或合金钢保护体，组合成复合轻质墙体材料；也有一些企业用聚苯乙烯泡沫为芯材，以金属网架为骨架，水泥砂浆作护围材料，组合成“ Foam Plastic Lightweight Fire-Resistant Boards The successful development of foam-cored wall materials is a new trend in the reform of wall materials. In recent years, it has developed rapidly in China, with polyurethane foam as the core material and steel or alloy steel. Protective bodies are combined into composite lightweight wall materials; there are also some companies that use polystyrene foam as the core material, metal mesh frames as the skeleton, and cement mortar as the enclosing material, which are combined into
