Description

Micro-powder reinforced polyurethane-based high-strength waterproof thermal insulation decorative integrated material and preparation method thereof Technical field

The invention relates to a micro-powder reinforced polyurethane-based high-strength waterproof thermal insulation decorative integrated material and a preparation method thereof.

Background technique

In recent years, real estate has flourished. With the improvement of building energy conservation, safety and environmental protection requirements, the development of building waterproof and thermal insulation materials has become an important topic in the construction industry. China is a country with large building energy consumption. The heating energy consumption per unit area is equivalent to 2 to 3 times that of countries with similar climatic conditions. Building energy consumption accounts for 1/3 of total social energy consumption. Building energy conservation has a long way to go; in addition, modern building requirements for waterproofing It is also getting higher and higher. How to solve the waterproof problem of buildings from the source is also the focus of modern architecture. Looking at the existing waterproof and thermal insulation materials at home and abroad, the following problems mainly exist:

(1) The waterproofing and heat preservation of existing building materials usually cannot be well balanced. The general thermal insulation effect of the organic building materials is high, the water absorption rate is high, the waterproof performance is greatly reduced, and the fireproof rating is low. The waterproofing effect of general organic building materials is low in strength and easy to damage, and can not meet the demand of high-strength integrated materials and long-term high-efficiency waterproof insulation for modern buildings.

(2) When the existing waterproof layer is constructed, various materials are required, and multiple constructions are required, and the process is complicated. In addition, most waterproof layers are expensive and cost about 80-110 yuan/m2.

(3) When the existing thermal insulation material adopts inorganic materials, it exhibits high water absorption rate, easy cracking, easy water seepage, and poor heat insulation and waterproofing effect during use.

(4) The current insulation materials such as EPS board, XPS board and PU rigid foam occupy more than 80% of the foreign wall insulation market. 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 the high fireproof standard.

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