［Objective］To solve the high reliance of polyacrylate water dispersion on petroleum-based chemicals in the production process，a low-carbon and environmentally friendly preparation route for acrylate was developed.［Methods］ In this study， vanillin acrylate（VA） and tetrahydrogeraniol acrylate（THGA）were used to replace traditional petroleum-based compounds toprepare different bio-based acrylate water dispersions and coatings. The influence of bio-based monomers on the performance of the products was investigated，and the renewable carbon content of the products was gradually increased.［Results］ The bio-based acrylic water dispersion（PMAIV） prepared with 25%VA and the dispersion（PMAIVT） prepared from 25%VA and 30%THGA allindicated good storage stability. The particle size distribution was uniform，and the prepared paint film indicated high thermal stability. The renewable carbon contents were 24. 99% and 51. 24%， respectively.［Conclusion］The two types of bio-based acrylic water dispersions obtained indicatedgood storage stability and mechanical stability. The resulting paint films showed good physical andmechanical properties and high gloss，providing a new route for the development of low-carbon andenvironmentally friendly waterborne acrylic coatings.
