Embodiment 1
[0032] It is an environment-friendly preparation method of rapid curing at room temperature and peelable blue glue, and its steps are as follows:
[0033] The first step: prepare modified styrene thermoplastic elastomer, tackifying resin, plasticizer, stabilizer, filler, solvent A, thixotropic agent and toner, the mass ratio of which is 1:0.5:0.05:0.001:0.5 :2:0.01:0.0001;
[0034] The second step: mix the tackifying resin, plasticizer, stabilizer, filler, solvent A, thixotropic agent and pigment together according to the above ratio, heat to 40°C, put it in a stirrer and stir at a low speed for 10 minutes to obtain Plasticizer system, the rotating speed of agitator low-speed stirring is 300 rpm;
[0035] The third step: Put the modified styrene thermoplastic elastomer into the mixer, heat it to 40°C, add the plasticizer system in the second step and stir at high speed for 20 minutes, cool and keep the temperature during the stirring process Below 70°C, the peelable blue glue ...
