“…Epoxy resins are one of the most important thermosetting polymers, which are widely used as high-performance protective coatings, structural adhesives, the matrices for fiber-reinforced composites, low-stress IC encapsulants, high-tech composites fields and other plastic engineering materials because of their strong adhesion, low shrinkage, high modulus, thermal stability, mold resistance and solvent resistance (Ma et al , 2020; Schaeur et al , 2002). Recent advances in waterborne technologies have now resulted in resin systems that may be used to produce high-performance epoxy primers, which are comparable to their solvent-borne counterparts.…”

Purpose A kind of the Z-6020/E-44 modified waterborne hydroxyl acrylate resin (Z-WEA) and its application in volatile organic compound-free waterborne coatings were prepared. Design/methodology/approach The Z-6020/E-44 modified waterborne hydroxyl acrylate resin (Z-WEA) was obtained dropwise by adding a mixed solution of methyl methacrylate, n-butyl acrylate, hydroxyethyl methacrylate, acrylic acid and an initiator into a pre-prepared solution of isopropyl alcohol and E-44 and by semi-continuous solution polymerization, and this chain was further extended with organosiloxane (Z-6020) through graft copolymer, which was then neutralized with organic base and dispersed with water, with waterborne amino resin curing agent to form a film, and the properties were tested. Findings The results showed that when the dosage of initiator was 2.5% accounts for the total acrylic monomer, the hydroxyl content was 10%; the dosage of E-44 was 16%; the dosage of Z-6020 was 6%; the mass ratio of hard and soft monomer was 2.0:1; the neutralization was 100%; Z-6020/E-44 modified waterborne hydroxyl acrylate resin (Z-WEA) had excellent dispersion performance in water and storage stability; water absorption of cured film was 7.8%; pencil hardness reached 5H; adhesive force was 1 level; and the film was uniform and endowed with remarkable heat resistance, high gloss and good fullness. Practical implications This paper established a method to synthesize Z-6020/E-44 modified waterborne hydroxyl acrylate resin (Z-WEA) with green surfactants that can be used in the coatings, adhesives, finishing agents and so on. Originality/value This paper provides a method of preparing Z-6020/E-44 modified waterborne hydroxyl acrylate resin (Z-WEA) and with waterborne amino resin curing agent to form a film, and the film is uniform and endowed with remarkable heat resistance, high gloss and good fullness and meets the requirements of high-grade paint.
