Abstract

The invention relates to the field of building materials, in particular to a flame-retardant thermal-insulation hollow brick and a manufacturing method thereof, wherein the hollow brick is prepared from the following raw materials in parts by weight: 20-28 parts of fly ash floating beads, 15-25 parts of expanded perlite, 3-6 parts of stearic acid, 1-5 parts of polyvinyl alcohol, 2-5 parts of antimony trioxide powder, 1-4 parts of decabromodiphenyl ether, 2-6 parts of expandable graphite, 6-10 parts of sericite powder, 1-4 parts of polystyrene, 0.6-1 part of a silane coupling agent KH570 and aproper amount of water. The flame-retardant thermal-insulation hollow brick provided by the invention can effectively overcome the defects of poor mechanical property and weak flame retardancy existing in an existing hollow brick.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a flame-retardant and heat-retaining hollow brick and a manufacturing method thereof. Background technique [0002] Hollow bricks are made of clay, shale, etc. as the main raw materials, and are made through raw material processing, molding, and sintering. They are light in weight, high in strength, and have good thermal insulation and noise reduction performance. In recent years, with the development of the construction industry and the progress of the whole society, people's living standards have been continuously improved, and more and more people are asking for houses with multiple functions such as high heat insulation, flame retardant, and durability. Higher requirements are put forward for the performance of hollow bricks. [0003] At present, Chinese patent CN106007641A discloses a thermal insulation and flame retardant hollow brick and its preparation method, which is ...
