Abstract
The invention provides a convenient tablecloth coating which is prepared from, by weight, 30-40 parts of room temperature self-crosslinking aqueous polyurethane, 0.05-0.1 part of flatting agents, 1-10 parts of wetting agents, 1-3 parts of thickening agents, 0.2-1 part of antifoaming agents, 0.10-0.30 part of antimycotic antibacterial agents, 2-5 parts of film formation auxiliary agents, 5-10 parts of water-based stripping agents and 10-20 parts of filler. The invention further provides a preparation method of the tablecloth coating. The method includes the steps that firstly, part of the wetting agents, the antifoaming agents and deionized water are added to a reaction container, stirring and dispersion are conducted, then the filler is added, stirring and dispersion are conducted again, the room temperature self-crosslinking aqueous polyurethane and the remaining antifoaming agents, the wetting agents, the flatting agents, the film formation auxiliary agents, the water-based stripping agents, the antimycotic antibacterial agents and the thickening agents are added for being evenly stirred, dispersion is conducted continuously, filtering is conducted after mixing, and the convenient tablecloth coating is obtained. The convenient tablecloth coating is easy to coat, convenient to replace, good in economy, resistant to wear and transparent.
Description
technical field [0001] The invention belongs to the field of polymer materials, in particular to a quick tablecloth coating and a preparation method thereof. Background technique [0002] With the rapid development of contemporary society, for people who love indoor life and work, the table is a good helper for people's life and work. Especially the desktop, almost everyone has to deal with various desktops every day. The tabletop should have a certain degree of wear resistance, stain resistance and decoration when it comes into contact with us.
