摘要
以三氟丙基甲基环三硅氧烷(D_3F)、八甲基环四硅氧烷(D_4)、四甲基四乙烯基环四硅氧烷(D_4Vi)作为单体,以短链乙烯基硅油作为封端剂,通过阴离子开环聚合的方式合成氟含量不同的乙烯基氟硅液体胶;通过阳离子开环聚合的方式分别合成了交联剂含氢氟硅油及Karstedt铂金催化剂,考察氟含量、乙烯基含量、填料含量等因素对加成型固化氟硅橡胶物理性能的影响。结果表明,当端乙烯氟硅液体胶含氟基团摩尔分数为30%、填料DM-30S的用量为31.5份时,固化后氟硅橡胶的邵尔A硬度可以达到44,拉伸强度达到8 MPa,断裂伸长率达到689%,撕裂强度达到38.9 kN/m。
Vinyl-terminated poly(methyltrifluoropropyl-dimethyl)siloxane with different fluorine contents were synthesized by anionic ring-opening polymerization,which using trifluoropropylmethylcyclotrisiloxane,Octamethylcyclotetrasiloxane and tetramethyltetravinylcyclotetrasiloxane as raw materials,short-chain vinyl silicone oil as capping agent.Hydrogen-containing fluorosilicone oil was synthesized by acid catalytic condensation reaction,using gas phased hydrophobic white carbon black as filler.Karstedt platinum catalyst was synthesized.Effects of fluorine content, vinyl content,and filler content on the physical properties of the addition-curing fluorosilicone rubber were discussed.Results showed that hardness could reach 44,and tensile strength reached 8 MPa,and elongation at break was 689% and tear strength was 38.9 kN/m when using 30% molar fluoro grouped vinyl-terminated fluorosilicone liquid glue and 31.5 part DM-30 S.
