Antibacterial finishing mortar

Abstract

The invention belongs to the technical field of building materials and provides antibacterial finishing mortar. The antibacterial finishing mortar is prepared from the following raw materials in parts by weight: 20-25 parts of silicate cement, 1-5 parts of nano-titania, 50-65 parts of quartzite sand, 5-8 parts of montmorillonite powder, 1-2 parts of polyanionic cellulose, 0.01-0.03 part of organosilicone modified polyester, 0.1-0.2 part of drier, 0.02-0.05 part of synergist and 0.1-0.15 part of antibacterial agent. The antibacterial finishing mortar has the beneficial effects that the antibacterial finishing mortar is a special mortar material, which is developed for architectural decoration, and is smooth in surface, short in setting time, high in setting strength and high in water absorbency, so that the propagation of bacteria caused by high indoor humidity is avoided; and meanwhile, through adopting materials with antibacterial functions such as polyester modified siloxane, polyacrylate, polysiloxane and hydrophobic modified silicon dioxide, human health can be protected, and the requirements of modern people on environment-friendliness, safety and the like of the building materials are met.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to an antibacterial plastering mortar. Background technique [0002] Plastering mortar refers to the mortar applied on the surface of buildings or building components, which can protect the base layer and increase the appearance. At present, latex paint, wallpaper, and wall covering are generally used for interior decoration in our country. These materials have some shortcomings, such as the smooth and dense surface of latex paint, large echo, and poor water absorption, resulting in high indoor humidity; wallpaper and wall covering are used in production and pasting. Adhesives produce formaldehyde and other gases, which are harmful to human health and have a short service life. There are potential safety hazards and cannot meet modern people's requirements for environmental protection and health of building materials. Contents of the invention [0003] Aiming at the de...
