Preparation method of thermal insulation coating material
The invention discloses a preparation method of a thermal insulation coating, and relates to the technical field of thermal insulation materials, and the preparation method comprises the following steps: preliminary preparation, preparation of a raw material A, preparation of a raw material B, preparation of a raw material C, preparation of a finished product, and coating for use. Pure calcium aluminate cement or high-alumina cement can keep good strength at the temperature of 200 DEG C or below, but the strength of the pure calcium aluminate cement or the high-alumina cement is sharply reduced along with temperature rise and crystal water discharge, but the strength of aluminum dihydrogen phosphate is in a trend of rising along with temperature rise, and the pure calcium aluminate cement and the high-alumina cement supplement each other, so that the pulverization phenomenon in the use process is avoided; on one hand, the requirement for the low heat conductivity coefficient is met, on the other hand, the strength is improved, the viscosity of the coating after water is added is improved by adding the silicon micropowder, the activated aluminum oxide micropowder, the cellulose, the water reducing agent and other additives, and coating construction is facilitated.
发明公开了一种隔热保温涂抹料的制作方法，涉及保温材料技术领域，所述步骤包括如下：初步准备，制备原料A，制备原料B，制备原料C，制得成品，涂抹使用，采用纯铝酸钙水泥或高铝水泥和磷酸二氢铝复合做主要结合剂，纯铝酸钙水泥或高铝水泥在200℃以下能保持较好的强度，但是随着温度升高，结晶水排出，强度会急剧下降，但是磷酸二氢铝随着温度升高强度呈上升趋势，二者相辅相成，避免了使用过程中粉化的现象，添加气相法白炭黑，一方面保证了低导热系数要求，另一方面增加了强度，添加硅微粉、活性氧化铝微粉、纤维素、减水剂等添加剂，增加涂抹料加水后的黏度，利于涂抹施工。
