Polystyrene board and other materials have fire resistance effect, which is easy to cause fire and cannot be used in large areas
Due to the low tensile strength and high water absorption of rock wool board, its application range is not wide
Some cement-based thermal insulation mortars and foamed cement products have unstable formulations during use, and it is difficult to control on-site construction, which affects thermal insulation and heat insulation effects
[0004] Putty is one of the important materials for architectural decoration and decoration. In addition to filling and leveling the defects of building walls, it can also play a variety of special functions such as waterproofing, reinforcement, crack resistance, and mildew resistance. However, the research on functional putty rare

Abstract
The invention discloses a thermal insulation putty and a preparation method thereof. The thermal insulation putty contains the following components: polymer emulsion: 10% to 30%; hollow ceramic microspheres: 7% to 15%; silica airgel: 1% to 10%; heavy calcium powder : 5% to 10%; talcum powder: 5% to 10%; fly ash floating beads: 5% to 10%; reinforcing fiber: 0.3% to 0.5%; additives: 1% to 3% , Auxiliaries include: dispersants, defoamers and antifungal agents; and the balance of water. The thermal insulation putty of the invention has the advantages of good thermal insulation effect, simple construction and good water seepage resistance.
Description
technical field [0001] The invention belongs to the technical field of chemical materials, and in particular relates to a thermal insulation putty and a preparation method thereof. Background technique [0002] The hot summer and cold winter region refers to the middle and lower reaches of the Yangtze River and its surrounding areas. The thermal insulation and insulation of exterior walls in this area has always been a difficult problem. Buildings must have thermal insulation in summer and thermal insulation in winter. The energy consumption of the enclosure structure accounts for more than 70% of the energy consumption of the entire building, and the outer wall is the main part of the enclosure structure. Due to the special climatic conditions in hot summer and cold winter regions, the external wall envelope structure measures that take into account both thermal insulation and heat insulation are not mature in the market. Although the light envelope structure composed of p...
