As an important organosilicon compound, diphenylsilanediol plays a key role in modification and composite material applications.

First, regarding the modification of diphenylsilanediol, it is characterized by its high reaction temperature and long reaction process, which makes it selective in the modification process. It can be used as a structural control agent for silicone rubber to reduce the structuring phenomenon of silicone rubber, thereby improving the processing performance of silicone rubber. In addition, diphenylsilanediol can also be used to synthesize phenyl silicone oil, phenyl silicone resin, phenyl silicone rubber, etc.

In the application of composite materials, the modification effect of diphenylsilanediol has been fully demonstrated. For example, it can be used as a modified intermediate for polyurethane resin, epoxy resin, acrylic resin, PP, PET, PE, etc., to give new products high and low temperature resistance, radiation resistance, aging resistance and other properties. Specifically, through a specific preparation process, diphenylsilanediol can be introduced into tung oil-based polyol to produce flame-retardant polyurethane rigid foam. This material not only has increased dimensional stability, but also has high flame retardant performance and flame retardant durability, and its limiting oxygen index can reach 26.50%.

In addition, diphenylsilanediol can also be used to prepare silicone cross-linking agents for LED chip packaging, showing its application potential in the optoelectronic field.

In summary, the modification of diphenylsilanediol and its application in composite materials are extensive and diverse. These applications not only improve the performance of the materials, but also promote the development of related industries. However, with the advancement of technology and changing needs, continuous research and exploration are still needed on the modification of diphenylsilanediol and its new applications in composite materials.
