[0056] The present invention also provides a kind of synthetic method of tackifier, comprises the following steps:
[0057] Mixing the silicone oil with the structure shown in formula (i) and the polar compound, heating and reacting to obtain the tackifier;
[0058]
[0059] In the synthetic method provided by the invention, in formula (i), R 0 for NH 2 -(CH 2 ) n - and / or SH-(CH 2 ) n -, n is an integer ≥ 0, specifically 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10.
[0060] In the synthetic method provided by the invention, in formula (i), R 2 , R 4 , R 5 , R 6 , R 7 and R 8 Both are based on R’-(CH 2 ) x - represents the same or different groups. Among them, R' is methyl, hydrogen, amino, mercapto, carboxyl, halogen, phenyl, trifluoropropyl, epoxy, vinyl, piperazinyl, N-(β-aminoethyl)-γ- Aminopropyl, one or more of γ-glycidyl etheroxypropyl and γ-methacryloyloxy, preferably one of vinyl, methyl, phenyl, trifluoropropyl and hydrogen atom or more, more preferably met...

[0080] Synthesize tackifier according to the reaction route shown in the following formula:
[0081]
[0082] Concrete synthetic steps include:
[0083] Add vinyl-terminated amino silicone oil and methyl acrylate into a glass reactor at a molar ratio of amino group to methyl acrylate of 1:2.5; at 50°C, mechanically stir (speed 100r / min) for 6 hours; The viscosity is 0.09MPa, and the thickener is obtained by distillation under reduced pressure at 60°C;
[0084] Wherein, the vinyl-terminated amino silicone oil is prepared according to the following steps:
[0085] Vinyl terminated simethicone (10 g), aminopropylmethyldiethoxysilane (100 g, 0.524 mol), water (18.9 g, 0.105 mol), KOH (0.0980 g, 0.00175 mol) and DMSO ( 1.0g) was added to a 250mL three-neck flask, equipped with a spherical condenser and a mechanical stirrer; the mixture was gradually heated to 100°C under heating in an oil bath, and stirred at reflux for 4 hours for hydrolysis prepolymerization; the mixture was...
