Example Embodiment
[0033] Example 1
[0034] A TPU hot-melt adhesive film with low melting point and high bonding strength, which is prepared in parts by weight from the following raw materials:
[0035]
[0036] The tackifier is petroleum resin.
[0037] The filler is kaolin.
[0038] The thickness of the adhesive film is 0.03-2mm, and the thickness of the adhesive film is uniform, which can be changed according to the thickness of the composite board.
[0039] The method for preparing TPU hot melt adhesive film with low melting point and high bonding strength as described above, the method includes the following steps:
[0040] (1) Dry the ingredients of the formula at 80-100°C;
[0041] (2) Extruding the dried raw material, cooling, winding, and packaging to obtain a TPU hot melt adhesive film.
[0042] Among them, an extruder is used for extrusion. The barrel temperature of the extruder is 120°C, 127°C, 155°C, 155°C, 147°C and 140°C, and the die temperature is, for example, 134°C, 131°C, and 131°C. ℃, 1...
