Preparation and Property Study of Organosilicon Antisticking Coatings

الملخص EN

In this article, an organosilicon antisticking coating was synthesized from vinyl silicone oil, hydrogen-containing silicone oil, and platinum catalyst.

Firstly, the methyl vinyl MQ (mono and quad) silicone resin was added.

When the silicone content was 30 wt.%, the shore hardness and tensile strength increased to about 27.4% and 115.9%, respectively.

Furthermore, nano-SiO2 powder was added to further improve its antisticking property.

This was due to the change of the surface roughness, which could greatly improve the antisticking performance.

When the nano-SiO2 powder content was 2 wt.%, the surface free energy and antisticking force were the lowest and the antisticking effect was the best as well and the mechanical properties of silicone rubber had been improved.
