Inorganic cooling coating and preparation method thereof
The invention discloses an inorganic cooling coating and a preparation method thereof. The coating is prepared from the following raw materials in parts by weight: 40-70 parts of magnesium oxide; 5-20parts of an additive; 0-30 parts of a filler; 0-5 parts of pigment; 0-5 parts of a modifier; and 30-80 parts of deionized water. The preparation method comprises the following steps: adding the filler, the pigment, the modifier and the magnesium oxide into the deionized water, mixing the components, adding the additive, continuously mixing the components, and forming the inorganic cooling coatingon the surfaces of cement, wood, stone and the like through spraying, brush coating or roller coating. The inorganic heat reflecting material takes magnesium oxide as a cementing material, which forms strong light scattering and infrared radiation together with functional filler. The inorganic heat reflection material is wide in raw material source, high in cost performance and simple in preparation process, has the sunlight reflectivity as high as 96% and the hemispherical emissivity as high as 0.94, and can be used for heat insulation and cooling of occasions such as buildings and industries.
本发明公开了一种无机降温涂层及其制备方法，该涂层由以下重量份的原料制成：氧化镁40～70份；添加剂5～20份；填料0～30份；颜料0～5份；改性剂0～5份；去离子水30～80份。制备方法包括：将填料、颜料、改性剂和氧化镁加入到去离子水中，混合，再加入添加剂持续混合，通过喷涂、刷涂或辊涂，可在水泥、木材、石材等表面形成无机降温涂层。该无机热反射材料以氧化镁为胶凝材料，并与功能填料共同形成强烈的光散射和红外辐射。本发明的无机热反射材料原料来源广、性价比高、制备工艺简单，并具有高达96％的太阳光反射率和0.94的半球发射率，可用于建筑、工业等场合的隔热降温。
