摘要

(CN106633175) 本​发明​公开​种​增强​蜜​胺​泡​绵​的​制备​方法，包括​如下​步骤：步骤​1：热固性​树脂​处理：使用​热固性​树脂​溶液，对​已经​发泡​成型​的​蜜​胺​泡​绵​进行​浸渍​或者​喷淋​处理，然后​对​蜜​胺​泡​绵​干燥；步骤​2：固化剂​处理：将​步骤​1​中​干燥​后的​蜜​胺​泡​绵​采用​固化剂​溶液​进行​浸渍​或者​喷淋​处理，得到​待​热处理​的​蜜​胺​泡​绵​前体；步骤​3：热​固化​工艺：在​100～200℃温度​下，将​待​热处理​的​蜜​胺​泡​绵​前体​放入​热​烘干​装置​中​进行​热​固化​处理；步骤​4：热​熟化​工艺：将​步骤​3​中​处理​后的​蜜​胺​泡​绵​置于​60～150℃的​热处理​装置​中​进行​热​熟化。通过​本​发明​得到​的​增强型​蜜​胺​泡​绵​外观​优良，热​收缩率​极小，孔隙​率​高，无​塌陷，回弹​率​高，适于​大规模​生产​应用​和​推广。
