AI Technical Summary

Technical Problem

Existing flame-retardant rubber sheets are prone to breakage when subjected to heavy impacts, and their flame-retardant effect is insufficient, failing to effectively buffer the impact force of heavy objects.

Method used

A high-strength flame-retardant composite rubber sheet was designed, which adopts a buffer flame-retardant mechanism, including a wave-shaped structure composed of a rubber layer and an internal metal plate. The flame-retardant components and metal strips are combined to form a cavity to improve the buffering and flame-retardant effect.

Benefits of technology

It effectively mitigates the risk of breakage caused by heavy impacts, improves the impact resistance and flame retardant properties of the board, reduces heat transfer, and enhances the overall performance.

Abstract

This utility model relates to a high-strength flame-retardant composite rubber sheet, belonging to the field of composite board technology. The high-strength flame-retardant composite rubber sheet includes: an upper substrate, with a lower substrate disposed at its lower end; a buffer flame-retardant mechanism disposed between the upper and lower substrates, the upper end of the buffer flame-retardant mechanism extending above the upper substrate, and the lower end extending below the lower substrate; wherein the buffer flame-retardant mechanism includes two flame-retardant components, the upper flame-retardant component being mounted on the upper end of the upper substrate; the rubber layer alleviates impact and enhances the impact resistance of the corrugated inner metal plate against the upper surface; the connecting strip and the arc-shaped plate cooperate to undergo compression deformation; the localized pressure of the rubber layer is concentrated on the protruding part of the lower inner metal plate, and the rubber layer in this area, combined with the circular holes, achieves better pressure resistance, forming a good buffer against weight, reducing the possibility of board breakage, and ensuring the performance of the sheet.
