| description | The invention discloses a preparation method of a tackifier for an addition type silicone pouring sealant, which comprises the following steps that (1) at room temperature of 25 DEG C, acrylic hydroxy ester and glycidyl ether alkoxysilane are evenly mixed; (2) while stirring, 1% wt of titanate is added, and after evenly stirring, the temperature is raised to 60-110 DEG C and the reaction is undergone for 1 to 8h to obtain a reaction mixture; and (3) a low-boiling-point substance is removed from the reaction mixture at a temperature of 80 DEG C and the degree of vacuum of 0.1MPa to obtain the tackifier. The thermal conductivity of the pouring sealant is improved by the tackifier prepared by the preparation method disclosed by the invention, and the pouring sealant added with the tackifier has good liquidity and meets pouring requirements. |
