【摘要】：为了寻找可替代生产酚醛树脂原料的可再生资源,制得性能优异的改性酚醛树脂。本论文考察了生物质对酚醛树脂性能的影响,研究了植物多酚、稀土金属化合物、油茶粕和油茶果壳等替代苯酚用量对改善酚醛树脂性能和降低生产成本的作用,并采用DMTA、FT-IR、TG等先进分析手段探讨了这些物质的作用机理。结果表明,植物多酚不仅提高了酚醛树脂的胶合强度,而且改善了酚醛树脂的韧性。稀土金属化合物可以提高酚醛树脂和植物多酚改性酚醛树脂的胶合强度；稀土金属化合物的结构对其作用效果影响大,本研究条件下,RE-a的作用效果最好。油茶粕和油茶果壳经改性和浸提后,都可用于酚醛树脂的合成,可替代20%以上的苯酚和甲醛,且所改性的酚醛树脂的胶合强度比普通的酚醛树脂大,不仅提高酚醛树脂的环保性、降低生产成本,而且为资源丰富的油茶加工剩余物开辟了一条高值化利用的新途径。
[Abstract]:In order to find the renewable resources to replace the raw materials for producing phenolic resin, a modified phenolic resin with excellent properties was prepared. In this paper, the effects of biomass on the properties of phenolic resin were investigated, and the plant polyphenols and rare earth metal compounds were studied. The effect of substitute phenol dosage such as Camellia oleifera meal and Camellia oleifera husk on improving the properties of phenolic resin and reducing the production cost was studied. The mechanism of these substances was discussed by advanced analytical methods such as DMTA-FT-IRTG. Plant polyphenols not only improve the adhesion strength of phenolic resin, but also improve the toughness of phenolic resin. Rare earth metal compounds can improve the adhesion strength of phenolic resin and plant polyphenol modified phenolic resin. The structure of rare earth metal compounds has great influence on the effect of phenolic resin, and the effect of RE-a is the best in this study. After modification and extraction of camellia oleifera meal and husk of Camellia oleifera, they can be used in the synthesis of phenolic resin and can replace more than 20% phenol and formaldehyde. The adhesive strength of the modified phenolic resin is larger than that of the ordinary phenolic resin, which not only improves the environmental protection of phenolic resin and reduces the production cost, but also opens up a new way of high value utilization for the processing residue of oil-tea with abundant resources.
