The invention provides a room-temperature curing high-temperature-resistant organic
silicon rubber
coating as well as a preparations method and application of the room-temperature curing high-temperature-resistant organic
silicon rubber
coating. The organic
silicon rubber
coating is prepared from an organic
silicon rubber material; and the organic
silicon rubber material is characterized in that amatching
system of a hydroxy-terminated polysiloxane
polymer containing different functional groups, modified white
carbon black reinforced filler, high-temperature-resistant and
antioxidant filler,high-temperature-resistant and
ablation-resistant filler and fibers is designed and used and is matched with a proper
polysilazane curing agent based on a mechanism of an interaction among an organicsilicon
polymer chain, the reinforced filler, the high-temperature-resistant and
antioxidant filler, the high-temperature-resistant and
ablation-resistant filler and the fibers in order to meet the harsh requirement for excellent comprehensive performances such as
room temperature curing, high
temperature resistance and high mechanical properties required in the use of the high-temperature-resistant organic silicon
thermal protection coating, so that the formula design of a high-temperature-resistant elastic coating is simplified, and the use of a
char forming agent capable of generating hugeinfluences to the mechanical properties is reduced.
