Lightweight thermal-insulation high-toughness fireproof plate and preparation method thereof
The invention discloses a preparation method of a lightweight thermal-insulation high-toughness fireproof plate. The lightweight thermal-insulation high-toughness fireproof plate takes a glass fiber mat as a core layer and resin and hollow glass beads as core layer dipping slurry, and is formed by hot pressing after dipping, and the preparation method comprises the following specific steps: preparing the core layer dipping slurry; impregnating the glass fiber mat into the core layer impregnating slurry to obtain a prepreg; and stacking the plurality of pre-impregnated materials and a piece of decorative veneering paper, and then carrying out hot press molding. Compared with the prior art, the glass beads are added into the fireproof plate, on the premise that the fireproof grade reaches the grade A of a non-combustible plate, light weight and heat preservation are achieved, and meanwhile the mechanical strength of the plate is improved by adding the glass fiber fabric. The internal weight is light, the hollow microbeads and the buffer material can effectively absorb shock and improve the structural safety, and the toughness of the internal structure is improved and the impact resistance is enhanced through the use of the glass fiber net. The fireproof effect is good, certain moisture-proof and waterproof effects are achieved, high temperature resistance is achieved, and the service life is long.
本发明公开了一种轻质保温高韧性防火板材的制备方法，是以玻璃纤维薄毡作为芯层，树脂和空心玻璃微珠作为芯层浸渍浆料，浸渍后热压而成，具体步骤为：配制芯层浸渍浆料；将玻璃纤维薄毡浸渍入芯层浸渍浆料，得预浸料；将若干预浸料与一装饰贴面纸堆叠后热压成型。与现有技术相比，本发明将玻璃微珠加入防火板材，在防火等级达到不燃板材A级的前提下还轻量保温，同时玻纤织物的加入提高了板材的力学强度。本发明内部质量轻，具有的中空微珠和缓冲材料，可有效减震，提高结构安全，通过玻纤网的使用提高内部结构的韧性，增强抗冲击力。防火效果好，还具有一定的防潮、防水效果、耐高温、使用寿命长。
