Problems solved by technology

[0002] The weather resistance and aging resistance of the existing flexible decorative bricks are low. According to the national industry standard "Flexible Decorative Bricks"
[0003] It is required that the aging resistance time of its artificial aging resistance is only 500-1000h, which is much different from the service life of building exterior wall insulation > 25 years, and the difference is even greater than that of building service life > 50 years. , Multiple replacements within the life cycle of the building, resulting in waste

Abstract

A weather-resistant and aging-resistant cement-based flexible facing brick disclosed by the invention comprises a cement-based decorative layer and a cement-based matrix. The cement-based decorative layer is prepared from, by weight, 30-80 parts of cement, 30-80 parts of fine aggregate, 0.6-6 parts of pigment, 6-40 parts of mixed glue solution of polymer emulsion or redispersible polymer glue powder and water, and 3-20 parts of water. The cement-based matrix is prepared from, by weight, 30-80 parts of cement, 30-120 parts of fine aggregate, 6-40 parts of mixed glue solution of polymer emulsion or redispersible polymer glue powder and water, and 5-40 parts of water. The flexible facing brick has the remarkable advantages of extremely excellent durability and weather resistance. After 2160 hours of all-weather aging test, the performance of the flexible facing brick is still the same as that of cement mortar and even slightly improved, while the existing product can only lasts 500-1000 hours. The flexible facing brick is exquisite in decoration effect, excellent in comprehensive performance, low in cost and suitable for building outer walls, inner walls and roofs.

Description

technical field [0001] The invention belongs to the technical field of production of building decoration materials, and in particular relates to a weather-resistant and aging-resistant cement-based flexible decorative brick and a manufacturing method thereof. Background technique [0002] The weather resistance and aging resistance of the existing flexible decorative bricks are low. According to the national industry standard "Flexible Decorative Bricks" [0003] It is required that the aging resistance time of its artificial aging resistance is only 500-1000h, which is much different from the service life of building exterior wall insulation > 25 years, and the difference is even greater than that of building service life > 50 years. , The building is replaced many times during the life cycle, resulting in waste. Therefore, it is of great significance to improve the weather resistance and aging resistance of flexible facing bricks. Contents of the invention [000...
