摘　　要：以甲基丙烯酸缩水甘油酯改性的衣康酸前聚体(GI)和环氧大豆油(ESO)的合成产品GIESO为原料,甲基丙烯酸四氢呋喃酯(THFMA)作稀释剂,制得疏水纳米SiO 2改性生物基UV固化树脂,然后引入含磷型阻燃剂9,10-二氢-9-氧杂-10-磷杂菲-10-氧化物(DOPO),制备了一种具有疏水和阻燃性能的UV固化木器涂料。通过调节树脂中SiO 2和DOPO的用量,研究了这两种组分对涂层性能的影响。研究结果表明:SiO 2用量为0.5%(以GIESO/THFMA的质量计,下同)时,涂层GIESO/THFMA-Si 0.5综合性能最佳,吸水率为0.49%,接触角108.2°。DOPO用量20%时,制得了一种具有较高涂膜性能,疏水性能和阻燃性能均较好的光固化木器涂料,涂膜硬度6H,附着力1级,柔韧性4 mm,接触角103.7°,极限氧指数(LOI)可达24.0%。Hydrophobic nano-SiO 2 modified bio-based UV curable resin was prepared using glycidyl methacrylate modified itaconic acid prepolymer(GI)and epoxy soybean oil(ESO)based synthetic product GIESO as raw materials and using tetrahydrofuran methacrylate(THFMA)as diluent.Then,9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide(DOPO)as a phosphorus-containing flame retardant was introduced to prepare a UV-curable wood coatings with hydrophobic and flame retardant properties.The effects of SiO 2 and DOPO on coating properties were studied by adjusting the relative contents of these two components in the resins.The research results showed that when the amount of SiO 2 was 0.5%(calculated by the mass of GIESO/THFMA,which was also applied as below),the comprehensive performance of the coating GIESO/THFMA-Si0.5 was the best,with a water absorption rate of 0.49%and a contact angle of 108.2°.When the dosage of DOPO was 20%,a UV-curable wood coatings with high film coating,hydrophobic and flame retardant properties was prepared.The hardness of film was 6H,the adhesion was level 1,the flexibility was 4 mm,the contact angle was 103.7°and the limiting oxygen index(LOI)was up to 24.0%.
