Modified furan resin composition for graphite impregnation
The invention provides a modified furan resin composition for graphite impregnation. The modified furan resin composition comprises the following components in parts by weight: 70-80 parts of biomass modified furan resin; 50 to 60 parts of ethanol; 0.5 to 1.2 parts of nano silicon powder; 0.5 to 1.2 parts of nano aluminum powder; the preparation method of the biologically modified furan resin comprises the following steps: S11, adding lignin and lignin-coated aluminum oxide composite nanospheres into 1/2 of a formaldehyde solution, adjusting the pH value to 10, and carrying out a heating reaction to obtain a mixture solution; and S12, adding a urea and 1/2 formaldehyde mixed solution into the mixed solution, continuing heating reaction, then adding 2/3-3/4 furfuryl alcohol, adjusting the pH value to 4, performing heating reflux reaction, cooling, performing vacuum dehydration, and finally adding the rest furfuryl alcohol to obtain the biomass modified furan resin. Lignin and lignin-coated aluminum oxide composite nanosphere modified furan resin are adopted, so that nanoparticles can permeate into pores of graphite, and the porosity and mechanical properties of the graphite are reduced.
本发明提供了一种石墨浸渍用改性呋喃树脂组合物，包括以下重量份成分：生物质改性呋喃树脂为70‑80份；乙醇为50‑60份；纳米硅粉为0.5‑1.2份；纳米铝粉为0.5‑1.2份；纳米氧化锆为1.5‑3.2份，所述生物改性呋喃树脂的制备方法包括以下步骤：S11.将木质素和木质素包覆氧化铝复合纳米球加入至1/2的甲醛溶液中，调节pH至10，加热反应，得到混合物溶液；S12.在混合溶液中加入尿素和1/2的甲醛混合溶液继续加热反应，然后加入2/3‑3/4的糠醇，调节pH为4，加热回流反应后，降温，真空脱水，最后加入剩余的糠醇，得到生物质改性呋喃树脂。本发明采用木质素以及木质素包覆氧化铝复合纳米球改性呋喃树脂，使得纳米粒子能够渗透到石墨的孔隙中，降低石墨的孔隙率以及机械性能。
