The invention discloses a high-
solid-content low-
viscosity low-hydroxyl-value low-
dilution-rate
alkyd resin, and a preparation method and applications thereof, and belongs to the technical field of
alkyd resin. The high-
solid-content low-
viscosity low-hydroxyl-value low-
dilution-rate
alkyd resin is prepared from, by weight, 17 to 23 parts of
oleic acid, 2 to 5 parts of
benzoic acid, 25 to 32 partsof a polyprotic acid, 22 to 32 parts of a
polyol, 0.05 to 2 parts of an anti-oxidant, 2 to 6 parts of a
backflow solvent, and 17 to 23 parts of a
dilution solvent. The high-
solid-content low-
viscosity low-hydroxyl-value low-dilution-rate alkyd resin is high in
solid content, low in viscosity, low in
hydroxyl value, low in dilution rate, quick in curing, high in
hardness, and less in smell. When the high-solid-content low-viscosity low-hydroxyl-value low-dilution-rate alkyd resin is used for preparing woodenware finish paint, following advantages are achieved: the woodenware finish : curing agent : diluents ratio is 3:1:1, the construction viscosity is (14+-0.5)s / 25 DEG C.
coating-4, obvious low dilution rate is achieved, the using amount of the curing agent and the diluents
solvent is reduced fully, energy saving and consumption reduction are achieved, after paint preparation, the VOC content is lower than 420g / L, and the duty free requirement that paint preparation construction VOC content is lower than 420g / L are satisfied.
