摘要
简要分析国内外木塑复合材料相关标准,解读新版标准GB/T 24508—2020《木塑地板》的重要指标,包括最小集中载荷、静曲强度和弹性模量、线性热膨胀系数、邻苯二甲酸酯总量、甲醛释放量、总挥发性有机化合物释放率,引导标准的正确理解和使用。
This article briefly introduced the development status of wood-plastic composite flooring and analyzed the relevant standards of wood-plastic composite products.The principle indexes of the newedition standard GB/T 24508—2020 were described,including the minimum concentrated load,modulus of rapture(MOR)and modulus of elasticity(MOE),the coefficient of linear thermal expansion,the phthalate content,formaldehyde emission,and the release rate of total volatile organic compounds(TVOC).These information provide a proper guidance for the application of the standard.
