A kind of antibacterial coating and breathable antibacterial film and waterproof breathable antibacterial film thereof

Abstract

The invention provides an antibacterial paint, an air-permeable antibacterial film, and a waterproof air-permeable antibacterial thin film containing the air-permeable antibacterial film. The antibacterial paint antibacterial paint is prepared from the following components in parts by weight: 16-20 parts of methyl methacrylate, 12-14 parts of butyl acrylate, 1-2 parts of nanometer TiO, 3-5 parts of sodium hydroxypropylate methacrylate, 1-2 parts of hydroxyl acrylic resin, 2-4 parts of polyoxyethylene ether, 1-1.5 parts of an emulsifying agent, 50-70 parts of deionized water, 1-5 parts of a pH adjusting agent and 1-5 parts of a film forming addition agent. The air-permeable antibacterial film comprises a surface layer, an antibacterial paint layer and a base material layer, wherein the antibacterial paint layer is coated on the base material layer; the surface layer and the base material layer are compounded; the base material layer comprises an antibacterial polyether type TPU surface layer, a first fabric, a common TPU jointing layer and a second fabric which are jointed from top to bottom, nanosilver antibacterial agents are added to materials of the antibacterial polyether type TPU surface layer, and the addition quantity of the nanosilver antibacterial agents is 2.5-5.5% of the mass of surface layer polyether type TPU.

Description

technical field [0001] The invention relates to the technical field of architectural films, in particular to an antibacterial paint, a breathable antibacterial film, and a waterproof, breathable and antibacterial film containing a breathable antibacterial film layer. Background technique [0002] In the breathable water-proof layer of houses in the construction industry, breathable films are often used to improve the life of the heat insulation materials inside the masonry and the heat insulation performance of the building itself. In addition, it is also used in some wooden structures. As a moisture-proof and waterproof material, it is mainly spread inside the ceiling or wrapped inside and outside the heat-insulating material inside the wall. Waterproof and breathable membrane is a new type of polymer waterproof material, and its technical requirements are much higher than that of ordinary waterproof materials. At the same time, waterproof and breathable membrane also has f...
