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。

Abstract

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 new-edition 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.
