Description
Technical field
The present invention relates to technical field of floor, more particularly to composite floor board and its manufacturing method.
Background technology
With timber resources growing tension and with the improvement of people ' s living standards, consumer is to the decoration on floor
Effect has higher requirement, and the contradiction of both proposes floor producer the new problem of the fast growing wood utilization of resources.At present
In the market, main solution is combined using precious hard broadleaf as incrustation plate, by base material of fast growing wood
Composite floor board, the most widely used product are multi-layer composite floor and three layers of composite floor board.However multi-layer composite floor by
Its substantial amounts of glue-line of its structures shape（Majority is 8 layers or 10 layers of glue-line）, thus the burst size of methanal of multi-layer composite floor
It is more difficult to control, and cost is excessively high if using low formaldehyde or formaldehyde-free glue, and the feel and solid wooden floor board of multi-layer composite floor
It differs greatly；Similary three layers of composite floor board derives from length by the stability of its width of itself structures shape and thickness direction
The sacrifice of directional stability, and when product has certain length, the prying power in timber length direction is big, when use environment is produced
The prying of length direction can cause the out-of-flatness mated formation during raw large change.
Two-layer composite floor plate and frame floor are had also appeared currently on the market.Double floor is as its name suggests by dash board and fast-growing
Material finger-jointed plate, OSB plates or other wood-based plates are combined for substrate, have to the moisture content control of manufacturing process dash board and substrate
Strict requirements, thus quality management and control is more difficult, the process-cycle is long.Frame floor, such as 201520942354.8 disclosure of Chinese patent
A kind of novel frame floor base material, including mainboard, mainboard both sides are equipped with side plate, and mainboard is spliced side by side by more battens；
The frame floor substrate stability of its own is improved, however as base material, with dash board it is compound after, dash board can not be solved
The problem on deformation brought with base material stabilization difference.
The content of the invention
An object of the present invention is to provide a kind of composite floor board, simple in structure, glue-line is few, stability is good；The present invention
The second purpose be to provide the manufacturing method of this kind of composite floor board, efficient, low manufacture cost.
One of technical purpose of the present invention technical scheme is that：A kind of composite floor board, including glue
The dash board and substrate connect is adhered, the substrate table side offers multiple tracks caulking groove, filler rod is equipped in the caulking groove；The caulking groove is along institute
Substrate width direction is stated through setting, and is equidistantly laid out along the substrate length direction；The caulking groove notch rectangular in cross-section, institute
Stating filler rod end face is in and the matched rectangle of the caulking groove.
Opening up by the caulking groove as a result, improves the stability in substrate length direction；By the setting of filler rod, with
Filler rod length direction is to dash board and substrate against improving the stabilization of the width of composite floor board of the technical program a kind of
Property；By the setting of dash board, the irregularity degree on thickness is reduced.
In the technical program, the material of preferred substrate is particieboard, oriented wood chipboard, one kind of high density fiberboard
