Abstract
The invention relates to an indoor self-cleaning coating based on a healthy building, which is composed of a primer coating and a surface coating; the primer coating is composed of 45% organic silicon modified alkyd resin, 6.7% precipitated calcium carbonate, and 0.3% fiber Plain nanofiber, 18.5% propylene glycol butyl ether, 15.3% titanium dioxide, 13.4% zinc sulfide, 0.8% additive; the surface coating is composed of a mixture of 0.1% alkyl ketene dimer and 99.9% n-heptane . In order to solve the problem that the nano-titanium dioxide self-cleaning coating is highly dependent on light, which is not conducive to indoor use and the organic silicon resin nano-coating has a short service life, the invention provides an indoor self-cleaning coating based on healthy buildings, which can improve the self-cleaning coating of the coating. cleanliness and longevity.
Description
technical field [0001] The invention relates to the technical field of coatings, in particular to an indoor self-cleaning coating based on healthy buildings. Background technique [0002] Self-cleaning coatings can be used on the surface of substrates (such as glass ceramics or wood and stone, etc.), relying on the hydrophobic and hydrophilic physical properties of the coating itself, it can play the role of antifouling and easy cleaning. Self-cleaning coatings can be divided into It is a superhydrophilic self-cleaning coating and a superhydrophobic self-cleaning coating. [0003] Super-hydrophobic self-cleaning coating Nano-titanium dioxide type super-hydrophilic self-cleaning coating, nano-titanium dioxide must have sunlight, more precisely, it must be stimulated by ultraviolet rays in sunlight to work, and it is very dependent on sunlight, which is not conducive to Use indoors. [0004] Super-hydrophobic self-cleaning coating means that water falls on the surface of the...
