Problems solved by technology

[0003] (1) The weather resistance is poor, and it will gradually age, and the service life will be relatively short
[0004] (2) It is not fireproof and easy to burn. It will decompose benzene volatile gas when exposed to high temperature, which can easily cause suffocation and death.
[0005] (3) The strength is low, the compressive strength is only 0.1-0.2MPa, the load-bearing capacity is small, and the safety and stability are poor
[0006] (4) The construction is difficult, professional construction is required, and the project cost is high
[0007] (5) Its resources are limited and it is difficult to recycle. The above-mentioned thermal insulation materials are all oily organic foam materials, which are mainly processed from petroleum, and are difficult to recycle and comprehensively utilize.
[0008] (6) The eco-environmental protection is very poor, which may cause new environmental protection problems
The wall insulation layer made of the above-mentioned plastic-related insulation materials is not only difficult to recycle, but also causes a great waste of resources and seriously pollutes the environment.

Description

technical field [0001] The invention relates to a construction mortar, in particular to an inorganic thermal insulation mortar used for building exterior walls and a preparation method thereof. Background technique [0002] With the intensification of the world's energy crisis and the further deterioration of the ecological environment, the contradiction between energy and environmental protection in my country has become more prominent due to the sustained and rapid economic development. It is required that the outer walls of buildings should be insulated. The construction of thermal insulation and energy saving has attracted the attention of the industry. The use will be amazing, and the existing building exterior wall insulation technology adopts expanded polystyrene board (EPS), extruded board (XPS), sprayed polyurethane (SPU) and rubber powder polystyrene particle insulation mortar. The above-mentioned thermal insulation materials are all organic thermal insulation mater...
