High-weather-resistant fireproof particle acoustic board and preparation method thereof
The invention provides a high-weather-resistance fireproof particle acoustic board and a preparation method thereof. The particle acoustic board is formed by bonding inorganic particles and an adhesive. The adhesive wraps the surfaces of the inorganic particles and is solidified, micropore channels exist among the particles, sound waves penetrate through the micropore channels and are consumed under the action of friction, resonance and the like, and then the sound absorption effect is achieved; the adhesive at least comprises the vinyl resin and the nano silicon dioxide resin, the vinyl resin molecular main chain is a stable carbon-carbon single bond, the vinyl resin molecular main chain is difficult to generate chain scission degradation under the action of light and damp heat under the outdoor condition, and the nano silicon dioxide resin has the characteristics of high hardness, noninflammability and the like; therefore, the two kinds of resin are used after being matched, the finally displayed performance is enough to be applied to manufacturing of outdoor particle boards, and then the weather-proof and fireproof performance of the acoustic board is effectively improved.
本申请提供的一种高耐候防火微粒吸声板及其制备方法，该微粒吸声板由无机颗粒和胶粘剂粘合而成；胶粘剂包裹在无机颗粒表面并凝固，颗粒之间存在微孔通道，声波穿透其中经过摩擦、共振等作用而被消耗，进而达到吸声效果；且本申请的胶粘剂至少包括乙烯基树脂和纳米二氧化硅树脂，由于乙烯基树脂分子主链是稳定碳碳单键，其在户外条件下受光，湿热的作用很难发生断链降解，且纳米二氧化硅树脂具有硬度高，不燃等特点；因此，本申请将两种树脂进行搭配后使用，最终展现的性能足够应用于户外微粒板的制作，进而有效提升吸声板的耐候防火性能。
