Prepn process of hydrophobic fireproof heat-insulating material

Abstract

The present invention is technological scheme of preparing hydrophobic fireproof heat-insulating material. The hydrophobic fireproof heat-insulating material is prepared with cement, fly ash, sierozem powder, glass fiber, expandable graphite, emulsion, water, etc. in certain weight proportion, and through mixing.

Description

technical field [0001] The invention relates to a building material, in particular to a preparation method of a hydrophobic flame-retardant thermal insulation material. Background technique [0002] The insulation of building materials is achieved by reducing the heat transfer coefficient of building materials, and there are many factors that affect the insulation effect. Among them, water seepage is an important factor. When water penetrates into the insulation layer, the insulation layer will be destroyed, and the thermal conductivity will increase accordingly. If it is enlarged, the thermal insulation function will be greatly reduced. At the same time, water seepage will have different degrees of adverse effects on the structure of the building and the comfort of people's lives. At present, the commonly used rubber powder polystyrene particle insulation slurry is mostly made of cement, calcium hydroxide, a small amount of polymer and stirred, then added with water and pol...
