A heat-fusion bonding adhesive is prepared by heating a thermoplastic resin to a temperature of no less than the softening temperature of the resin and then dispersing the resin in the softened state in an aqueous medium. Dispersing the thermoplastic resin in the aqueous medium is conducted, for example, by applying a shear force to the aqueous medium by stirring. In this case, stirring of the aqueous medium is preferably conducted till the thermoplastic resin is divided into particles with a weight-average particle size of 0.1-20µm.
热熔粘合剂的制备方法是将热塑性树脂加热至不低于其软化温度,然后将软化状态的树脂分散在水介质中。例如,通过搅拌对水介质施加剪切力,可将热塑性树脂分散在水介质中。在这种情况下,最好对水介质进行搅拌,直到热塑性树脂分散成平均粒径为 0.1-20µm 的颗粒。
