Abstract

A high-weatherability nanometer composite material for buildings comprises the following raw materials in percent by weight: 20-40% of natural chevkinite modified powder, 15-30% of mica-quartzose schist powder, 10-15% of fine muscovite powder, 5-10% of hole-closed perlite, 15-30% of ceramic micro powder, and 5-10% of heavy calcium powder. By reasonably selecting the raw materials, the high-weatherability high-acid-alkali-resistance nanometer composite material for buildings is obtained, is applied to building external walls for prolonging service life of buildings, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a nanocomposite material for high weather resistance buildings. Background technique [0002] Because the nano-dispersed phase has the characteristics of large specific surface area and strong interfacial interaction, and thus produces quantum effects and surface effects, nanomaterials not only exhibit properties different from general macroscopic materials, but may also have special properties that the original components do not have. And functions, it has broad prospects for the preparation of high-performance, multi-functional composite materials. [0003] For a long time, the houses that people live in have changed from the earliest mud constructions to the walls of the concrete buildings. The current wall not only has a stronger structure, but also looks very beautiful overall. Now with the acceleration of urbanization, the construction industry is booming, and ...
