Embodiment 1
[0056] S1. In a reaction kettle with a stirrer and a condenser, put in the solvent methylcyclohexane, butanone and SBS elastomer according to the formula, and dissolve at room temperature for 2 hours;
[0057] S2. After the SBS is completely dissolved, add the monomers methyl methacrylate, vinyl acetate, and acrylic acid; raise the temperature to 80°C under normal pressure, and add the initiator BPO;
[0058] S3. Stir and react for 3-5 hours at 85-90°C with a rotation speed of 80-120 rpm, allowing the SBS elastomer to be synthesized by grafting monomers to obtain high-molecular polymers;
[0059] S4. Cool down to 60°C, add the polymerization inhibitor BHT;
[0060] S5. Cool down to below 40°C, add a certain amount of tackifying resin terpene resin, petroleum resin, glycerin resin, and rosin;
[0061] S6. Stir evenly, the appearance is slightly yellow and clear, and the detection viscosity range is 4000~5000CPS at room temperature. After the index is qualified, it can be disch...

Embodiment 3
[0096] S1. In a reaction kettle with a stirrer and a condenser, put in the solvent methylcyclohexane, butanone and SBS elastomer according to the formula, and dissolve at room temperature for 2 hours;
[0097] S2. After the SBS is completely dissolved, add the monomers methyl methacrylate, vinyl acetate, and acrylic acid; raise the temperature to 80°C under normal pressure, and add the initiator BPO;
[0098] S3. Stir and react for 3-5 hours at 85-90°C with a rotation speed of 80-120 rpm, allowing the SBS elastomer to be synthesized by grafting monomers to obtain high-molecular polymers;
[0099] S4. Cool down to 60°C, add the polymerization inhibitor BHT;
[0100] S5. Cool down to below 40°C, add a certain amount of tackifying resin terpene resin, petroleum resin, glycerin resin, and rosin;
[0101] S6. Stir evenly, the appearance is slightly yellow and clear, and the detection viscosity range is 4000~5000CPS at room temperature. After the index is qualified, it can be disch...
