Production method of antibacterial coating, antibacterial coating and ventilated antibacterial film containing antibacterial coating

Abstract

The invention provides a production method of an antibacterial coating, the antibacterial coating and a ventilated antibacterial film containing the antibacterial coating. The production method comprises the following steps: S1: weighing materials in a raw material formula in parts by weight; S2: adding cyclomethyl methacrylate, butyl acrylate, nano TiO, methacrylic acid hydroxylpropyl sulfonic acid, acrylic resin, polyoxyethylene ether, an emulsifying agent, de-ionized water, a pH regulator and a film-forming addition agent into a mixer and pre-stirring, wherein the stirring speed is 3000rpm/min to 6000rpm/min and the stirring time is 0.1h to 0.2h; S3: fusing and extruding the mixed raw materials obtained by the step S2 through an extruder, tabletting and crushing through a tabletting machine, micro-crushing by a crusher and screening in a rotary manner in sequence to finally obtain antibacterial coating powder. The production method of the antibacterial coating, provided by the invention, is finished through three steps; the production process method is simple and the production method is simple; the production time is short and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of architectural films, in particular to a method for producing an antibacterial coating, to the antibacterial coating produced by the method, and to a breathable antibacterial film containing the antibacterial coating. 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...
