Embodiment 1
[0040] The preparation method of the vegetable oil-based flame-retardant polyurethane acrylate prepolymer of the present embodiment comprises the steps:
[0041] (1) in reactor, add 10.00g epoxidized soybean oil (ESO), 6.03g diethylphosphonoacetic acid and the catalyst 1 of 1% of total feeding weight 1,8-diazabicycloundec-7-ene ( DBU), the molar ratio between the epoxy group in epoxidized soybean oil and the carboxylic acid group in diethylphosphoacetic acid is 1:3, stir evenly and heat up to 130°C, react for 8h, and obtain bio-based Phosphorus polyol (PCSO).
[0042] (2) At room temperature, mix 1g of hydroxyethyl acrylate (HEA) with 13.46g of the bio-based phosphorus-containing polyol (PCSO) obtained in step (1), and then mix 3.83g of isophorone diisocyanate (IPDI) And the catalyst dibutyltin dilaurate (DBTDL) of 1% of total feed weight is slowly dripped, then add the polymerization inhibitor hydroquinone of 0.5% of total feed weight, stir, the isophorone diisocyanate isocy...
