摘　　要：本工作探究了利用农林废弃物中的花椒剩余物(Pepper residue,PR)作为一种新型的原料替代部分桉木刨花进行刨花板生产的可行性,使用不同添加量的PR刨花制备桉木/PR混合刨花板,测试了板材的各项物理力学性能与热稳定性。结果表明,花椒剩余物适合作为刨花板的生产原料。当使用脲醛(UF)树脂胶黏剂的板材PR添加量为30%时,静曲强度/弹性模量(MOR/MOE)数值达到了15.02 MPa/2827 MPa;当使用异氰酸酯(MDI)胶黏剂的板材PR添加量为10%,MOR/MOE数值达到了15.44 MPa/2490 MPa。其力学性能均远高于刨花板国家标准GB/T 4897-2015中干燥状态下使用的家具型刨花板(P2型)的最低要求。The feasibility of using pepper(Zanthoxylum bungeanum Maxim)residue in agricultural and forestry wastes as a new raw material to replace part of Eucalyptus shavings for particleboard production was explored.Eucalyptus/PR mixed particleboard was prepared by adding different amounts of PR particleboard.The physical and mechanical properties and thermal stability of the panel were tested.The results showed that PR was suitable for the production of particleboard.The MOR/MOE value of the plate with 30%PR of UF resin adhesive reached 15.02 MPa/2827 MPa;the MOR/MOE value of the plate with 10%PR of MDI adhesive reached 15.44 MPa/2490 MPa.Both of them are far higher than the minimum requirements for furniture type particleboard(P2 type)used in the dry state in the Chinese national standard GB/T 4897-2015.
