    • The present invention provides one-pack type curing paste material to be used in a method of mechanically mixing and dispersing a low-pressure gas into a paste material to produce an expandable material, followed by discharging and expanding the expandable material to produce a curable product, especially a cured product with dense uniform closed-cells by using a mechanical foaming apparatus suitable for performing of the method. The one-pack type curing paste material of the present invention has viscosity characteristics included in the zone defined by points A, B, C and D in the graph of FIG. 1 showing the relationship between shear rate and apparent viscosity, said points A and B being at 50-30000 poises of an apparent viscosity (measured by a Brookfield rotary viscometer using spindle No.7, at 2 rpm, at 20° C.) in low shear rate region (0.43 sec−1) and said points C and D being at 20-2000 poises of an apparent viscosity (measured by an apparent viscosity meter according to JIS K2220, at 20° C.) in high shear rate region (783 sec−1).
    • 本发明提供了一种单组分固化糊料材料,用于将低压气体机械混合和分散到糊料中以制备可膨胀材料的方法,然后将可膨胀材料排出和膨胀以产生可固化产物 特别是通过使用适于执行该方法的机械发泡装置的具有致密均匀闭孔的固化产物。 本发明的单组分固化糊剂材料具有包含在由图A的曲线图中的点A,B,C和D定义的区域中的粘度特性。 1表示剪切速率和表观粘度之间的关系,所述点A和B的表观粘度为50-30000泊(通过使用锭号7的Brookfield旋转粘度计,以2rpm,20℃测定)在 低剪切速率区域(0.43秒-1),所述点C和D的表观粘度为20-2000泊(根据JIS K2220的表观粘度计,在20℃下测定) )在高剪切速率区域(783秒-1)。
