Summary: | The invention relates to low-odor flame-retardant acrylic polyurethane resin as well as a preparation method and application thereof, and the low-odor flame-retardant acrylic polyurethane resin comprises the following components in percentage by weight: (1) 20-25% of at least one unsaturated vegetable oil fatty acid; (2) 10%-15% of at least one (methyl) acrylate or vinyl monomer; (3) 0.1%-1% of at least one initiator; (4) 4%-8% of at least one polyol; (5) 3%-8% of at least one phosphorus-containing polyol compound; (6) 5%-10% of at least one isocyanate monomer; (7) 0.1%-0.3% of at least one catalyst; (8) 0.1%-0.5% of at least one end-capping reagent; and (9) 45%-50% of at least one low-odor solvent used for surface protection of electronic devices. Compared with the prior art, the method has the advantages that the polyurethane is chemically grafted with the acrylic resin, and the unsaturated vegetable oil fatty acid is used for cross-linking modification of the polyurethane; a flame-retardant material 9, 10- |
