HIGH TEMPERATURE-RESISTANT DAMPING THERMOPLASTIC SILICONE RUBBER MATERIAL CAPABLE OF BEING REPEATEDLY PROCESSED, PREPARATION METHOD THEREFOR, AND USE THEREOF

WIPO Patent Application WO/2023/169042

A1

The present invention provides a high temperature-resistant damping thermoplastic silicone rubber material capable of being repeatedly processed, a preparation method therefor and the use thereof. The thermoplastic silicone rubber material comprises the following components in parts by weight: 20 to 40 parts of a thermoplastic component; 35 to 55 parts of silicone rubber; 5 to 20 parts of a plasticizer; 5 to 20 parts of a damping agent; 2 to 12 parts of a filler; 0.5 to 1 part of a crosslinking initiator; 0.5 to 1.5 parts of a crosslinking promoter; and 0 to 1.5 parts of other auxiliaries. The number average molecular weight of the damping agent is 150 to 8000, and the crosslinking promoter contains unsaturated fatty chains. The material has a good damping effect even at a high temperature, and the loss factor tanδ min at between -50°C and 150°C is greater than or equal to 0.45.
