AI Technical Summary
Technical Problem
The existing aqueous hydroxyacrylic acid dispersions have the disadvantages of high VOC content, large viscosity, low solid content and unstable solid content, and it is difficult to simultaneously reduce viscosity and increase solid content.
Method used
The three -step method is used instead of two -step method to introduce duodrilitanol and uncle carbonated glycerol glycol alcohol as a base solvent, and use the core shell structure synthesis method and the use of multi -heterropic acrylate monomers to reduce the VOC and viscosity of the product. At the same time, improve the solid.
Benefits of technology
Effectively reduce the viscosity and VOC of hydroxyl acrylic scattered body, improve the solid and stability, and overcome the shortcomings of common synthetic methods.

Abstract
The invention relates to a water-based hydroxy acrylic dispersion and a preparation method thereof, and relates to the technical field of paints.The preparation method comprises the steps that under inert atmosphere protection, a priming solvent is heated to the specified temperature, a first mixed solution is added, and the mixture is dispersed uniformly and reacts sufficiently; adding the second mixed solution and the neutralizer, uniformly dispersing again, and fully reacting; and adding a third mixed solvent, uniformly dispersing, adding water, and filtering to obtain the water-based hydroxy acrylic dispersion. Compared with the prior art, the prepared water-based hydroxyl acrylic dispersion has the advantages that the solid content of the product is increased while the annual length is not greatly increased, and the obtained water-based hydroxyl acrylic dispersion is low in VOC (volatile organic compound).
