摘要:使用自制的木质素酚醛树脂(LPF)与普通酚醛树脂(PF)按一定比例混和,再与填料及各种助剂炼塑并粉碎成木质素酚醛模塑粉,再压成制品。对制品进行性能测试,LPF占树脂的质量分数为60%时(LPF-60)制品性能很好,其弯曲强度78.0 MPa,冲击强度3.65 kJ/m2,热变形温度174.03℃。SEM分析表明LPF-60的断面比较平整。TG分析表明该模塑粉耐热性能较好,400℃失重8.89%,800℃失重58.16%,1000℃失重93.39%。
Lignin phenolic resin (LPF) mixed with common phenolic resin (PF) at certain mass ratio were added with fillers and additives to plasticate, grinded into LPF molding power, and then were pressed to products. The results of property test showed that the product with 60 % mass fraction of LPF (LPF-60) had better physical properties, flexural strength is 78.0 MPa, impact strength is 3.65 kJ/m^2 and heat deflection temperature is 174.03 ℃. The TG analysis showed that the molding power had better heat resistance, mass loss were 8.89 %, 58.16 % and 93.39 % at 400, 800 and 1000 ℃, respectively.
