Preparation method of macromolecular silicone rubber tackifier

The invention discloses a preparation method of a macromolecular silicone rubber tackifier, and belongs to the technical field of tackifier preparation. The preparation method is characterized by comprising the following steps: a, adding bis(trialkoxysilylpropyl)allyl isocyanurate and boric acid ester into a three-neck bottle provided with a water segregator, starting stirring, conducting heating to 90-100 DEG C, conducting refluxing for 2-4 hours under an acidic condition, transferring the reaction system into a distillation device, conducting reacting until no fraction flows out, and adding sodium bicarbonate for neutralization to prepare an intermediate; b, preparing a tetrahydrofuran coordination complex solution; and c, dropwise adding the intermediate and a tetrahydrofuran coordination complex solution, conducting balancing at 90-100 DEG C for 2 hours, adding activated carbon, fully conducting mixing, and conducting filtering to obtain the macromolecular silicone rubber tackifier.
