Compression-molded heat-insulation mute rubber-plastic acoustic board and preparation method thereof

The invention relates to a compression-molded heat-insulation mute rubber-plastic acoustic board and a preparation method thereof. The compression-molded heat-insulation mute rubber-plastic acoustic board comprises a butyl rubber, a cis-polybutadiene rubber, polyvinyl chloride, a high-temperature foaming agent, antimonous oxide, zinc oxide, epoxidized soybean oil, an anti-aging agent, an antioxidant, protective wax, polyethylene glycol, stearic acid, aluminum hydroxide, a pore forming agent, an anti-scorching agent, a light stabilizer, sulfur and the like. According to the invention, the rubber-plastic foaming material is uniform and porous in foam holes, the density of the material is greatly reduced, the heat conductivity coefficient of foamed rubber and plastic can be increased, and a good heat insulation effect is achieved. 本发明涉及一种模压成型绝热静音橡塑吸声板及其制备方法，包括丁基胶、顺丁橡胶、聚氯乙烯、高温发泡剂、三氧化二锑、氧化锌、环氧大豆油、防老剂、抗氧剂、防护蜡、聚乙二醇、硬脂酸、氢氧化铝、开孔剂、防焦剂、光稳定剂、硫磺等。使橡塑发泡材料泡孔更加均匀多孔，大大的降低材料本身的密度，同时可以提高发泡橡塑的导热系数，达到很好的绝热作用。
