The present invention discloses water dispersed automobile finishing varnish of polyacrylate and its preparation process. The water dispersed automobile finishing varnish is mixture of water dispersed polyacrylate, water dispersed curing agent amino resin and closed polyisocyanate. The polyacrylate is water dispersoid prepared with the mixture of five components, and through the first radical initiator initiated polymerization in mixed solvent to obtain polyacrylate resin and the subsequent neutralization with neutralizer. The water dispersed automobile finishing varnish after being sprayed and cured forms varnish film possessing high glossiness, high brightness, high hardness, high impact resistance, high weather resistance, high compactness and fast adhesion to the base material.
Description
A kind of water-dispersed acrylate automotive finish paint and preparation method thereof technical field The invention relates to a water-dispersed acrylate resin-containing automotive finish paint and a preparation method thereof. Background technique At present, my country's automotive coatings are still mainly solvent-based, and a large amount of volatile organic compounds (VOC) cause serious pollution to the environment during the coating process. Countries around the world have successively formulated relevant regulations to limit the emission of VOC in paint. In order to meet the requirements of environmental protection, automotive coatings are developing in the direction of water-based, high-solids and powder coatings, among which water-based technology is the most beneficial to environmental protection and has attracted much attention. Water-based automotive coatings mainly use water as the dispersion medium and contain a small amount of volatile co-solvents, so ...
