Environment-friendly light thermal insulation material and preparation method thereof
The invention belongs to the field of thermal insulation materials, and particularly discloses an environment-friendly light thermal insulation material and a preparation method thereof. The environment-friendly light thermal insulation material comprises a low-density inorganic thermal insulation layer and a protective layer. The protective layer wraps the outer side of the low-density inorganicthermal insulation layer, the low-density inorganic thermal insulation layer is composed of furnace slag, inorganic fibers, opacifier, inorganic adhesive, limestone and nanoparticles, the protective layer is made of non-woven fabric materials, and a low-permeability gas barrier film is arranged on the surface of the protective layer. The environment-friendly light thermal insulation material is light in weight, capable of effectively reducing the load of industrial equipment, capable of reducing the transportation cost, convenient to carry, high in temperature resistance stability, high in heat insulation performance, capable of being recycled, capable of saving energy and environmentally friendly, and the heat conductivity coefficient w/(m.K) of the material at 500 DEG C is within 0.01 and has no linear shrinkage change.
本发明属于绝热材料领域，具体公开了一种环保型轻质绝热材料及其制备方法，包括低密度无机绝热层和保护层，所述保护层包裹在低密度无机绝热层外侧，所述低密度无机绝热层由炉渣、无机纤维、遮光剂、无机胶黏剂、石灰石、纳米颗粒组成，所述保护层由无纺布材料制成，所述保护层表面设置有低渗透阻气膜。本发明轻质、有效减轻工业设备荷重、降低运输成本、搬运便捷，具有高耐温稳定、高绝热性能，500℃导热系数w/(m·K)在0.01以内且无线形收缩变化，且可循环使用，节能环保。
