Abstract

The invention relates to a nanometer intelligent thermal insulation and heat preservation material for a building outer wall and a preparation method thereof. The nanometer intelligent thermal insulation and heat preservation material is prepared from porous nano SiO2, nano rutile type TiO2, nano composite suspended emulsion, vitrified hollow glass beads, an inorganic light-weight material, a functional additive and pure water. Compared with the traditional heat preservation board material, the nano intelligent thermal insulation and heat preservation material for the building outer wall has the advantages of light weight, thin layer, good thermal insulation and heat preservation effect, simplicity in construction, high efficiency, resource conservation, low construction comprehensive cost, safety, environmental protection and the like and is a novel nano intelligent thermal insulation and heat preservation material for the building outer wall. The nano new-tech product of the invention can adjust the nano intelligent thermal insulation and heat preservation technical indexes according to different energy-saving and emission-reduction technical requirements of different building thermal technology climate zones, the wall body structure and the engineering so as to achieve a best engineering application effect and ideal cost performance.

Description

【Technical field】 [0001] The invention belongs to the technical field of thermal insulation materials for building exterior walls. More specifically, the present invention relates to a nano-intelligent thermal insulation material for building exterior walls, and also relates to a preparation method of the nano-intelligent thermal insulation material for building exterior walls. 【Background technique】 [0002] At present, my country's high energy consumption building area accounts for more than 95% of the total building area, and the heating energy consumption per unit area is equivalent to 5 to 8 times that of developed countries with similar climate conditions. Building energy consumption is huge. Therefore, my country has clearly stipulated energy conservation and emission reduction standards in urban construction planning, design, construction and use, and building construction must carry out thermal insulation treatment of external walls. However, due to the traditional...

Problems solved by technology

However, due to the traditional passive building heat insulation boards, such as EPS boards, XPS boards, PU hard foam and other organic heat insulation boards, inorganic mineral wool, rock wool boards and other materials, due to their complex engineering construction technology and many auxiliary materials, comprehensive High cost, unsatisfactory insulation effect, large amount of materials used, waste of resources and energy, and serious pollution, poisonous, harmful, and flammable during production and use construction, etc., often cause major accidents, which seriously affect and Restricts the development of my country's building thermal insulation and energy-saving technology and the overall technical level of the material industry

[0003] The fire performance of traditional building organic heat insulation boards and the mechanical connection of building walls are poor

Major fire accidents in building exterior wall insulation projects and accidents of overall collapse, falling off and hurting people happen from time to time, resulting in serious losses and causing adverse effects on the society.

These major fires and collapse accidents and negative preventive measures have greatly limited the application of traditional building insulation panels in construction projects

However, inorganic thermal insulation panels, such as rock wool, mineral wool, glass wool, and foamed concrete, have poor mechanical properties, strong water absorption, and even failure when exposed to water due to loose fibers. It is difficult to achieve ideal thermal insulation in construction projects. effect, and serious pollution in production and construction, which has direct harm to workers
