AI Technical Summary

Technical Problem

The use of organic solvents is difficult to completely avoid in the preparation of existing waterborne hydroxyacrylic acid dispersions, which affects the environment and human health.

Method used

A solvent-free hydroxyl acrylic acid dispersion was prepared by using α-methylstyrene dimer, glycidyl tert-carbonate, and ethylene tert-carbonate as reactive diluent monomers through two-step free radical polymerization. The neutralization and water dispersion processes were combined to avoid the introduction of organic solvents.

Benefits of technology

The prepared dispersion is environmentally friendly and solvent-free, with adjustable molecular weight and excellent polymer properties. The resulting two-component polyurethane coating is stable during storage and has high gloss, high hardness, good water resistance, and excellent acid and alkali resistance.

Abstract

The application discloses a preparation method of a solvent-free hydroxyl acrylic dispersion and application thereof. The preparation method takes alpha-methyl styrene dimer (AMSD), glycidyl ester of versatic acid (E-10P) and vinyl versatate (vv-10) as reactive active diluent monomers, and through two-step free radical polymerization, low-viscosity and low-molecular-weight hydroxyl acrylic resin is obtained, and then through neutralization and water dispersion processes, finally, the water-based hydroxyl acrylic dispersion is obtained. The method does not introduce organic solvents in the whole preparation process, and the prepared dispersion truly realizes green environmental protection. The dispersion can be matched with a water-based isocyanate curing agent, and is used as a two-component polyurethane coating, the obtained coating has excellent storage stability, and the paint film has the advantages of high gloss, high hardness and good water resistance.
