METHOD FOR PRODUCING FIRE-RESISTANT THERMALLY INSULATING BOARD |
摘要 |
<p>A method for producing a fire-resistant, thermally insulating board, which comprises applying liquid hydrated sodium silicate (B) onto the inner surface of a facing material or sheet (A), spreading powdery hydrated sodium silicate (C) over the said applied surface, laying the said spread surface on (1) a facing material or sheet (D), (2) a facing material or sheet (D) applied in advance with liquid hydrated sodium silicate (B) or (3) a facing material or sheet having powdery hydrated sodium silicate (C) spread further over the applied surface of (2), implementing the heating and pressing procedure for gluing the assembly, and laminating the resulting fire-resistant board (E) with rigid isocyanurate foam (F). The fire-resistant, thermally insulating board shows reduced fusing and combustion of the rigid isocyanurate foam (F) even when exposed to flame and posseses superior mechanical properties.</p> |
