NOVELTY - The utility model claims a new fireproof sealing rubber strip with graphene expansion strip; the outer side of the sealing rubber layer is provided with a fireproof layer and a wearable layer; the sealing rubber layer is provided with a graphene strip; the graphene strip is provided with a buffer structure; the buffer structure is provided with an expansion ball structure; the lower part of the sealing rubber layer is provided with a mounting rubber column and a mounting rubber tooth; the inner part of the mounting rubber column is provided with an outer supporting cabin; the inner part of the outer supporting cabin is provided with an elastic metal supporting sheet through a fixing plate; The utility model makes the buffer performance of the sealing rubber strip better by the buffer structure in the sealing rubber layer; at the same time, the fireproof layer is matched with the graphene strip to improve the fireproof performance of the sealing rubber strip; the graphene powder in the expansion ball structure graphene powder cabin expands the expansion ball body after being heated and is filled with buffer cabin; so that the sealing rubber strip has better sealing and fireproof performance when meeting the fire; and the mounting rubber tooth is matched with the elastic metal supporting sheet to make the sealing rubber strip easily adapt to the mounting groove with different sizes; the universal performance is greatly increased.
