Abstract

The invention relates to a processing technology of a novel antibacterial and mildew-proof building material, and belongs to the technical field of building materials. The processing technology of theantibacterial and mildew-proof building new material comprises the following steps: (1) burdening; (2) mixing and ball milling; (3) mixing the mixed and ball-milled raw materials with other raw materials except water; (4) feeding the mixed raw materials into a stirrer, adding water, and stirring the raw materials to obtain slurry; (5) carrying out standing treatment; (6) pouring the slurry afterstanding into a forming mold, and then trowelling, closing the mold and curing the slurry; (7) demoulding the shaped material to obtain a blank, and maintaining and drying the demoulded blank; and (8)carrying out burr finishing on the blank to obtain the antibacterial and mildew-proof new building material. The antibacterial and mildewproof nanoparticles can play antibacterial and mildewproof roles, can effectively prevent the interior of a building adopting the material from mildewing, have an antibacterial effect, can improve the indoor environment quality, and meet the requirement of people for the indoor environment comfort level.

Description

technical field [0001] The invention relates to a processing technology of a new antibacterial and antifungal building material, which belongs to the technical field of building materials. Background technique [0002] With the development of the economy and the progress of society, various high-rise buildings, bridges and tunnels have sprung up like mushrooms, and the use of cement as a building material is indispensable behind these large-scale construction projects. Cement is a powdery hydraulic inorganic gelling material. After adding water and stirring, it becomes a slurry, which can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. It is one of the three basic materials of the construction industry, with a large amount of use and a wide range of applications, and is known as "the food of the construction industry". Due to its relatively excellent performance and low production cost, it is widely used in ...
