Abstract

The invention discloses an anti-bacterial coating for glass surface and a preparation method of the anti-bacterial coating, and relates to the field of glass coatings. The anti-bacterial coating comprises raw materials in parts by weight as follows: 30-40 parts of silicone emulsion, 1.5-2.5 parts of negative ion powder, 1-3 parts of zinc borate, 2-4 parts of copper pyrithione, 3-5 parts of silver-embedded nano titania, 3-5 parts of nano-zinc oxide, 4-7 parts of nano silica, 2-4 parts of a chitosan-copper complex, 0.4-0.9 parts of a silane coupling agent, 0.7-1.2 parts of an antistatic agent, 0.4-0.9 parts of an ultraviolet absorbent, 0.1-0.4 parts of a dispersing agent and 0.2-0.6 parts of an antifoaming agent. Under the synergistic effect of the components, the coating has excellent adhesive force, coating performance and ageing resistance and outstanding antibacterial property, is not prone to pulverization or falling and can effectively inhibit breeding of surface bacteria.

Description

technical field [0001] The invention relates to the field of glass coatings, in particular to a glass surface antibacterial coating and a preparation method thereof. Background technique [0002] Glass is an important part of the field of inorganic non-metallic materials science and engineering, and also an important family of amorphous solids. Human beings have conducted research and innovation on traditional glass and invented many new functional glass materials whose properties and functions are completely different from traditional glass. Glass science has become a new type of applied science. [0003] With the advancement of science and technology and the improvement of people's living standards, people pay more and more attention to environmental sanitation. In life, it is not uncommon for people to experience discomfort caused by microorganisms and bacteria that grow in kitchens and bathrooms. Therefore, consumers are very eager for daily necessities to have steriliz...
