Preferably, the composite floor substrate, on the tube wall of first tubule and the tube wall of second tubule
On open up multiple ventholes.
The present invention is include at least the following beneficial effects:
1, the present invention by being laid with web and thin plate respectively between bottom plate and core plate and core plate and dash board, in enhancing base
The pressure resistance of material, resistance to deformation performance while, improve bottom plate, the ventilating air permeability of core plate and dash board to each other, pass through design level
The substrate of shape structure has the web of preferable ventilated performance with the pressure resistance of enhancing base materials, the performance of resistance to deformation, can
Prevent substrate because internal moist or uneven heating it is even caused by drying shrinkage, the bulking even generation of metaboly, thin plate lower surface is also
Equipped be conducive to core plate inner air and external air currents the second tubule, further promoted substrate gas permeability, thin plate it is another
One effect is can to close the toxic gas inside core plate, is reduced in core plate to the toxic gas that dash board is mobile；And fiber
Designed in net and thin plate with external through-hole be connected to, the hot-air overstock substrate inside, humid air and toxic can be discharged in time
Gas avoids substrate from the case where warpage and cracking, the simple production process for the composite floor substrate that the present invention designs, ventilation occur
Permeability is good, has the advantages that greening and environmental protection, is worth large-scale popularization on the market；
2, the sawdust of the different-grain diameter of timber of the same race is mixed to get mixing wood-fibred by the core plate that designs of the present invention, and three kinds
The sawdust of different-grain diameter mixes, and reduces the gap between fiber, combines closely between fiber, reduces the internal stress between fiber, mention
The density and intensity of high core plate limit bulking or the contraction of core plate to the maximum extent, and enhance the density of substrate, improve base
The intensity of material, the anti-deformation of enhancing base materials；
3, the grid lines of web is designed as hollow, and the upper end of the first tubule on web is protruded into inside core plate, lower end
It protrudes into inside the grid lines of web and communicates therewith, so that the air inside core plate can pass sequentially through the first tubule, web
Grid lines, the first circular groove and third through-hole and outside air carry out convection current, the moisture in core plate by air stream all
