High-strength anti-stretching sealing strip and application thereof

The invention relates to the field of sealing strips, in particular to a high-strength anti-stretching sealing strip which comprises a main body structure and an anti-stretching structure, and the anti-stretching structure is wrapped or semi-wrapped by the main body structure; the main body structure comprises the following materials in parts by weight: 100 parts of vinyl-containing silicone rubber, 50-60 parts of a filling agent, 6-10 parts of an anti-structuring agent, 0.5-3 parts of a metal complex, 1-3 parts of a conditioning agent and 4-6 parts of a vulcanizing agent. The main body structure and the anti-stretching structure are made of the same materials, on one hand, the compatibility between the main body structure and the anti-stretching structure is increased, the phenomenon of cracking in a special environment is avoided, on the other hand, the main body structure has high strength, the anti-stretching structure has excellent tensile property, and the service life of the anti-stretching structure i
