A micropowder-reinforced polyurethane-based high-strength waterproof, thermal insulation and decorative integrated material and its preparation preparation method

technical field

The invention relates to a micropowder-reinforced polyurethane-based high-strength waterproof heat preservation and decoration integrated material and a preparation method thereof.

Background technique

In recent years, real estate has developed vigorously. With the improvement of people's requirements for building energy saving, safety and environmental protection, the research and development of building waterproof and thermal insulation materials has become an important topic in the construction industry. my country is a country with large building energy consumption. The energy consumption per unit area of heating is equivalent to 2 to 3 times that of countries with similar climate conditions. Building energy consumption has accounted for 1/3 of the total energy consumption of the society. Building energy conservation has a long way to go. In addition, modern buildings require waterproof How to solve the waterproof problem of buildings from the source is also the focus of attention of modern buildings. Looking at the existing waterproof and thermal insulation materials at home and abroad, there are mainly the following problems:

(1) The waterproof and thermal insulation of the existing building materials are usually not well balanced. Generally, the organic building materials with good thermal insulation effect have high porosity and high water absorption rate, and their waterproof performance is greatly reduced, and their fire protection rating is low. Generally, organic building materials with good waterproof effects have low strength and are easily damaged, which cannot meet the needs of modern buildings for integrated materials with high strength and long-term efficient waterproof and thermal insulation.

(2) During the construction of the existing waterproof layer, there are various types of materials required, and multiple constructions are required, and the process is complicated. In addition, the cost of most waterproof layers is high, and the cost is about 80-110 yuan/㎡.

(3) When the existing thermal insulation material adopts inorganic materials, it shows the defects of high water absorption rate, easy cracking, easy water seepage and poor thermal insulation and waterproof effect during use.

(4) At present, organic insulation materials such as EPS board, XPS board, and PU rigid foam occupy more than 80% of the external wall insulation market in my country. Although this type of organic thermal insulation material has the characteristics of small thermal conductivity and good thermal insulation performance, its fireproof performance is poor and cannot meet high fireproof standards.

(5) Due to the low degree of integration of the construction process, cracks of different degrees often appear on the window sills, columns, beams, etc. of the exterior walls of the building. During the maintenance and use process, these cracks will expand and deepen, which will lead to the destruction of the thermal insulation and waterproof system. And this is just a difficult point of existing building exterior wall design, construction.

Therefore, high-efficiency, energy-saving, green, safe, and low-cost waterproof, thermal insulation and decorative integrated materials have good industry competitiveness and market prospects.
