生物油的氨基甲酸酯化改性及其酚醛树脂的制备
Carbamatization of Bio-oil and Its Derived Phenolic Resins
摘要
Abstract
The conversion of the bio-oil into carbamate was carried out in accordance with the mass ratio of bio-oil and urea 100:20, 100:30 and 100:50 and achieved the carbamate bio-oil UO-20, UO-30 and UO-50 that were then used to synthesize and the biomass phenolics UOR-20, UOR-30 and UOR-50. The carbamate bio-oil and its derived phenolic resins were characterized, and the cure and thermal properties of the carbamate bio-oil derived phenolic resins were investigated. The results showed that the introduction of amino groups in bio-oil during carbamatization was beneficial for the preparation of biomass phenolics. With the increase of bio-oil amination degree, the softening point and gelation temperature of biomass phenolics reduced; there were two endothermic peaks at 178 and 205 ℃ during the cure process of biomass phenolics. Meanwhile, the benign rheological property and machine shaping were equipped; the char-yield of biomass phenolics at 800 ℃ and nitrogen environment could reach to 42%-46%. The thermal decomposition temperature these biomass phenolics could reach to 245-325 ℃, indicating that these biomass phenolics have a benign heat resistance.关键词
