AI Technical Summary
Existing mica fireproof boards are prone to punching cracks or penetrating cracks around the pressure relief holes during the production process, resulting in a pressure relief threshold of less than 0.5MPa, which affects quality and processing yield, and increases production costs.
The mica fireproof board with a honeycomb structure is made of surface-modified mica powder and double-cured modified silicone water. It forms a three-dimensional network structure through cross-linking and curing, which enhances mechanical properties and heat resistance, avoids cracking problems during stamping and die cutting, and recycles scraps to reduce costs.
It improves the production yield and quality stability of honeycomb mica fireproof panels, reduces production costs, meets the needs of automakers for burst threshold, and provides long-lasting thermal runaway protection.
