| titleOfInvention | A kind of additional organosilicon rubber tackifier and preparation method |
| abstract | The invention discloses the method that one kind prepares additional organosilicon rubber tackifier by the use of acidic cationic resin as catalyst, hydrolytic condensation method, prepared tackifier can be used for the addition-type silicon rubber application field with cementability requirement.The present invention is raw material using alkoxy silane of the three kinds or more containing different degrees of functionality, it is that solvent controls condensation reaction degree simultaneously using methanol or ethanol, catalyst is used as by the use of acidic cationic resin, part cohydrolysis condensation is carried out under the conditions of 40 ~ 80 °C, is filtered to remove and a kind of water white transparency is obtained after resin cation and removed under reduced pressure solvent and low volatile, the siloxane oligomer tackifier that the degree of polymerization is 3 ~ 6.The tackifier are suitable to the Si―H addition reaction silicon rubber system with cementability requirement.Present invention process control is simple and reaction condition is gentle, has preferably controllability and reappearance.It is expected to be used widely in fields such as electronic enterprises, LED chip encapsulation, photovoltaic bondings. |
