AI Technical Summary

Technical Problem

Existing fast-drying coatings use toxic benzene, toluene, and xylene solvents and have a slow drying speed, making it difficult to meet the coating and production rhythms of large industrial machinery.

Method used

The formulation uses a component free of benzene, toluene, and xylene, including chlorinated vinyl resin, epoxy resin, modified phenolic resin, modified alkyd resin, rust inhibitor, common filler, pigments and fillers, thickener and organic solvent. A paint film drying agent is prepared by reacting N,N-bis-salicylaldehyde ethylenediamine, zinc sulfate and ethanol. After mixing, a fast-drying coating is formed.

Benefits of technology

The prepared quick-drying coating film dries rapidly, has strong adhesion, good impact resistance and flexibility, excellent salt spray resistance, and is environmentally friendly, thus improving the construction efficiency and market competitiveness of engineering machinery.
