Abstract

Negative ion water-based coating is provided. The coating well achieves dissolution and dispersion of a negative ion additive in the water-based coating and a better negative ion release effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a negative ion water-based coating and a preparation method thereof. Background technique [0002] Water-based paint uses water instead of traditional organic solvents as the main solvent or dispersion medium, and its water content is about 20% to 50%. Water is used as the diluent, that is, water is used as the medium, and it does not contain toxic heavy metals such as benzene, formaldehyde, and free TDI. [0003] In recent years, water-based paint, as an energy-saving, environmentally friendly, green and safe clean paint, has received more and more attention and attention in various industries in our country. [0004] Water-based coatings are widely favored mainly because of their following advantages: [0005] (1) The main raw material used to produce water-based coatings is renewable energy. Water-based paint contains more than half of water. Water is a clean and renewable e...
