Description

technical field [0001] The invention mainly relates to the technical field of polymer materials, in particular to a bio-based low-VOC (Volatile Organic Compounds, ie, volatile organic compounds) aqueous emulsion and a preparation method thereof. Background technique [0002] Solvent-based coatings are coatings made from organic solvents as the dispersion medium. This type of coating affects all aspects of our lives, such as paint, waterproof coating, and coating on home surfaces. [0003] With the improvement of people's living standards, the call for environmental protection is also increasing. There are a large number of organic solvents in solvent-based coatings as dispersion media. The emission of these volatile organic compounds (VOC) not only endangers human health, but also pollutes the air and environment. Contents of the invention [0004] The technical problem to be solved by the invention [0005] The present invention provides a bio-based low-VOC water-based ...
