Example Embodiment
[0027] Embodiment 1: low temperature resistant high temperature resistant high and low temperature universal hot melt pressure sensitive adhesive and its preparation
[0028] raw material:
[0029]
[0030]
[0031] Preparation:
[0032] Step 1: Heat naphthenic oil, white oil or their mixture to 140°C, add SIS, wait for it to dissolve, discharge, cool in natural state, and set aside.
[0033] The second step: add a small amount of petroleum resin, and after it is melted, add amorphous α-olefin copolymer 1, 2, 3 in stages to dissolve it, and control the temperature at 160 ° C at this time.
[0034] The third step: add the spare material of the first step and stir, after it is fully dissolved, add PB in stages, after the dissolution is uniform, lower the temperature to 140 ° C, add terpene resin and C5 hydrogenated petroleum resin, and wait for it to melt Afterwards, antioxidants are added, the mixture is kept stirring for 30 minutes, and the material is discharged to ob...
