The surface wear resistance of 10 kinds of stone plastic floor samples was tested by using the drop sand GB/T 34440-2017 standard,200 conversion sandpaper abrasion method in LY/T 2716-2016 standard and 500 conversion sandpaper abrasion method in LY/T 3303-2022 standard,respectively.The results show that there is a linear correlation between the natural logarithm of wear revolutions of 500 conversion sandpaper and that of 200 con-version sandpaper,and the correlation coefficient R2 is 0.967 4.When the thickness of the wear layer is the same,the lower the volume loss value of the drop sand method,the higher the wear revolutions of the 500 conversion sand-paper method and the 200 conversion sandpaper method.
