Problems solved by technology

For coatings with antibacterial properties, if some small-molecule antibacterial agents are added, first, some components have an unpleasant taste, and second, the short-term effect of small-molecule antibacterial agents is good, but with the migration of small-molecule antibacterial agents, the antibacterial effect will be reduced. fall quickly
For coatings with wear-resistant properties, a part of wear-resistant fillers are usually added, but the addition of wear-resistant fillers will have a certain impact on the flatness of the coating surface; if you want to have both characteristics, it is more difficult to control

Abstract

The invention provides a graphene based anti-bacterial and wear-resistant double-component coating. According to the specific scheme, the coating contains a component A and a component B, wherein thecomponent A is prepared through steps as follows: an acrylic polymer aqueous dispersion is taken as a substrate, and graphene supported titanium dioxide serving as an anti-bacterial agent, 2-acryloyloxyethyl tributylphosphonium chloride-trimethoxy vinyl silicon oligomer containing fluoroalkyl as well as other auxiliaries are added; the component B is ketimine; graphene supported titanium dioxide is prepared from 1-10 mu m graphene oxide, 10-15 nm titanium dioxide particles and a silane coupling agent through uniform dispersion in water, reduction and drying. Acrylic polymers are subjected to monomer selection, glass beads are introduced, so that wear resistance is improved, a final product has excellent anti-bacterial performance, wear resistance, stain resistance and adhesive force, and the coating with the excellent anti-bacterial performance and wear resistance is suitable for being used in hospitals and schools with large volume of people.

Description

technical field [0001] The present invention relates to the field of antibacterial and wear-resistant two-component coatings, in particular to the field of graphene-based antibacterial and wear-resistant two-component coatings, and the invention further relates to a preparation method for antibacterial and wear-resistant two-component coatings , application and method of use. Background technique [0002] As the most commonly used building material in building decoration, paint is used to cover walls, and its most basic function is to be beautiful. Coatings in the prior art are usually high molecular polymers, and acrylic polymers are commonly used. With the increasing requirements for environmental protection in building decoration, water-based coatings have become a hot spot in research and development. [0003] Functionalized coatings are a popular direction, which can not only play a decorative role, but also impart other functional properties, such as antibacterial, w...
