    • PURPOSE: Provided is a fireproof insulation-coating composition with a low specific gravity by including water-carrying materials instead of conventional foaming agent for forming pores in compacts. CONSTITUTION: The low specific gravity coating composition is prepared by mixing 75-85wt.% of main composition comprising portland cement, expanded perlite, mineral fiber, calcium carbonate and aluminum hydroxide with 15-25wt.% of polyacryl amide and potassium acrylate saturated with water in a ratio water/polymer of 200 to 500. Also the coating composition is prepared by mixing main composition, 0.05-4wt.% of water-carrying agent(powder), and water. The resultant compositions are coated on the surface of steel and concrete by a sprayer or trowel, resulting in 5-15% of decrease in density.
    • 目的:提供一种具有低比重的耐火绝缘涂料组合物,其中包括含水材料代替常规发泡剂,用于在压块中形成孔隙。 构成:低比重涂料组合物是通过将75-85wt%的主要组合物与波特兰水泥,膨胀珍珠岩,矿物纤维,碳酸钙和氢氧化铝混合15〜25wt。%的聚丙烯酰胺和饱和的丙烯酸钾 水/聚合物的比例为200-500。另外,通过将主要组合物,0.05-4重量%的载水剂(粉末)和水混合来制备涂料组合物。 所得组合物通过喷雾器或t刀涂覆在钢和混凝土的表面上,导致密度降低5-15%。
