ALPHA-SILANE COUPLING AGENT AND APPLICATION THEREOF
-
Paragraph 0062, (2019/02/13)
The present invention discloses an α-silane coupling agent and application thereof. The α-silane coupling agent has a structure formula of formula (I): R1 is alkyl with 1 to 6 carbon atoms; R2 is alkyl with 1 to 6 carbon atoms; R3 is alkyl with 1 to 6 carbon atoms; R4 or R5 is selected from one of hydrogen, alkyl with 1 to 18 carbon atoms, aryl, benzyl, ester-containing group, carbamido-containing group or heterocyclic alkane; R4 and R5 are the same or different. The α-silane coupling agent is applied to silicone rubber, which can be cured without adding a catalyst, and the curing speed is fast; the α-silane coupling agent has strong reactivity, the surface curing time is less than 2 minutes; and the α-silane coupling agent has good stability, which can be stored stably under conditions at room temperature for 6 months, and does not easily turn yellow.
