Expansion type fireproof plate and preparation method thereof
The invention relates to an intumescent fireproof plate and a preparation method of the intumescent fireproof plate. The intumescent fireproof plate comprises an adhesive, a catalyst, a charring agent, a foaming agent and filler, the adhesive comprises the following components in parts by weight: 20-60 parts of an adhesive; 10 to 30 parts of a catalyst; 20 to 40 parts of a charring agent; 1-30 parts of a foaming agent; 0-10 parts of a filler; wherein the mass ratio of the charring agent to the catalyst to the foaming agent is (1-5): (1-3): 1. According to the expansion type fireproof plate, a compact and firm expansion carbon layer can be formed at high temperature, the strength of the carbon layer of the fireproof plate can be enhanced, oxygen supply is effectively isolated, flame spreading is blocked, heat transfer is slowed down, and therefore the heat insulation performance of the expansion type fireproof plate is improved. Compared with a traditional fireproof plate, the expansion type fireproof plate provided by the embodiment of the invention has more excellent fireproof performance.
本申请涉及一种膨胀型防火板及膨胀型防火板的制备方法，该膨胀型防火板包括：粘合剂、催化剂、成炭剂、发泡剂和填料；各组分的重量份为：粘合剂20份～60份；催化剂10份～30份；成炭剂20份～40份；发泡剂1份～30份；填料0份～10份；其中，所述成炭剂、催化剂和发泡剂的质量比为(1～5):(1～3):1。本申请实施例的膨胀型防火板在高温下能形成致密坚固的膨胀碳层，能增强防火板的碳层强度，有效隔离氧气的供应阻断火焰的蔓延，减缓热量传递，以提高膨胀型防火板的隔热性能。相较于传统的防火板，本申请实施例的膨胀型防火板具有更优异的防火性能。
