Shanghai Pulitong New Material Technology Co., Ltd. has obtained a project entitled "a room temperature curing self-adhesive silicone composition and its preparation method and application", authorized notice No. CN116083045B, the application date is December 2022.

The patent abstract shows that the invention belongs to the technical field of organic silicone rubber, and more specifically relates to a room temperature curing self-adhesive silicone composition and a preparation method and application thereof. By combining two alken-based sealed polydimethylsiloxanes with different viscosity, the fluidity and toughness of the silicone composition can achieve better balanced performance, and the mechanical properties of the silicone composition can be adjusted by choosing the mass ratio of two alken-based sealed polydimethylsiloxanes with different viscosity, which can adapt to the requirements of different substrates and application scenarios. The invention also creatively synthesizes a silyl ether tackifier with an alken-based structure, and the tackifier has good compatibility with the system, and can greatly improve the adhesive force on a variety of substrates. The preparation of the organosilicon composition of the invention has simple operation and mild conditions, and is suitable for large-scale industrial production.
