Description

Technical Field

[0001] The invention relates to the technical field of building materials, and in particular to an energy-saving heat-insulating material for building construction. Background Art

[0002] Energy conservation and environmental protection have become major issues that humans must face in the 21st century, and have also become important issues that our construction industry must focus on solving. Improving the thermal insulation performance of houses is an important measure for building energy conservation and consumption reduction. Under the advocacy of the state, many new buildings and many old buildings are applying thermal insulation layers on the exterior and interior walls to achieve the thermal insulation effect in the house, that is, in the hot summer, the thermal insulation materials of the interior and exterior walls are used to prevent heat radiation from transmitting into the house, reducing the energy consumption of household appliances such as air conditioners, and in the cold winter, the thermal insulation materials of the interior and exterior walls are used to prevent the high indoor temperature from being transmitted to the cold outdoors. At present, the thermal insulation layer materials used in the market are mainly polymer organic and inorganic materials. Commonly used polymer thermal insulation materials include: expanded polystyrene foam board, cross-linked polyethylene foam board, and foamed polyurethane board. Inorganic material boards include: foamed cement board and foamed magnesium oxychloride cement board. The main advantages of organic material boards are low density, high thermal insulation efficiency, and good toughness. The disadvantages are poor fire resistance, easy to ignite after catching fire, and toxic smoke will be produced during the combustion process, which seriously endangers life safety. There are also defects such as poor aging resistance, short service life, complex installation procedures, and high costs. The advantages of inorganic material thermal insulation layers are: low cost, difficult to burn, no smoke generated during fire, good aging resistance, the same life as the building, easy installation, and low cost. The disadvantages are that it will increase the overall weight of the building and the material lacks toughness.

[0003] Although the current thermal insulation materials have good thermal insulation effects, the materials are easily penetrated and cracked, and their own sound insulation effect needs to be improved by installing sound insulation boards, resulting in defects in the effect of the thermal insulation materials themselves. An energy-saving thermal insulation material for construction is needed to solve this problem. Summary of the invention
