2）使用数控海绵切割机切割泡棉材料形成沙发造型的海绵体；
3）配置表面涂层剂A和表面涂层剂B，所述的表面涂层剂A由聚氨酯预聚体85-90重量份、聚碳酸酯5-10重量份，消泡剂6800 0.5-1重量份、乙二酸丁二酸酯5-10重量份混合后升温至70-90℃反应5-6小时制成，表面涂层剂B由甲苯二异氰酸酯60-70重量份、异佛尔酮二异氰酸酯20-30重量份、碳酸丙酯5-10重量份、山梨醇5-10重量份、抗菌纳米粉1-3重量份和环氧树脂1-3重量份混合后升温至65-85℃反应2-3.5h制成；
4）对沙发造型的海绵体除底部以外的表面先用表面涂层剂A涂饰，再用表面涂层剂B涂饰；
5）表面涂层干燥；
6）配置底面涂层剂，所述的底面涂层剂由甲苯二异氰酸酯70-80重量份、玻化微珠4-8份重量份、羟丙基甲基纤维素2-6重量份和乙二酸聚酯10-15重量份混合后升温至90-120℃反应1.5-2.5h制成；
7）对沙发造型的海绵体除底部用底面涂层剂涂饰；
8）底部涂层干燥；
9）采用表面涂层剂A再次向沙发造型的海绵体除底部以外的表面进行远距离喷涂形成表面颗粒机理；
10）使用弹性抗UV漆对沙发造型的海绵体进行涂饰；
11） UV颜色固化；
12）干燥；
