  • Silicone rubber and phenolic modified silicone rubber and methods for preparing the same
    Patent number: 11254790
    Abstract: The present invention discloses a silicone rubber and a method for preparing it, and a phenolic modified silicone rubber resin and a method for preparing it. The structural formula of the silicone rubber is shown as follows: Wherein x=70-80, y=10-20. The structural formula of the phenolic-modified silicone rubber resin is shown as follows: wherein n, x, y are degrees of polymerization, n=10-20, x=70-80, y=10-20. A method for preparing the phenolic-modified silicone rubber resin orderly comprises: adding 90-110 parts by mass of brominated phenolic resin and 180-220 parts of organic solvent into 100 parts by mass of silicone rubber, reacting at 70-80° C. for 24-48 h until the solution is clear and transparent; adding 9-11 parts by mass of capping agent, reacting for another 4-5 h to obtain a reaction liquid containing phenolic-modified silicone rubber resin.
