Abstract

Sustainable wood floor (WFF), produced from natural plants, is a sort of novel green and ecofriendly composite floor, which has been attracting more and more attention in the world. WFF also gives a solution of utilizations of agricultural wastes, such as bamboo mats and hemp hurd. The additive limestone powder plays key role in the performance of flexible bamboo composite floor, so, in this paper, the effects of limestone size and size distributions were investigated. The best particle size distributions of limestone are 25 wt% of 48 μm, 25 wt% of 106 μm, and 50 wt% of 160 μm. The as-obtained WFF has good elasticity, good affinity, and strong comfortableness as well as free formaldehyde release.

Highlights

With globally rapid development of industrialization and urbanization, energy saving and greenhouse gas (GHG) mitigation have become ones of the most extensive issues [1,2,3,4,5]
WFF was carried out by using independent flexible bamboo fiber floor production line; the mechanic properties were tested by WDT-5 tension and compression spring tester; DMA242 was applied to characterize the mechanical properties of materials as a function of time and temperature
The impacts of limestone particle size and size distribution on the performance of wood fibre reinforced composite floor are shown in Table 2 and Figure 3
