Abstract
Disclosed is a board core. Powder or thread or strip or sheet materials made of dried bamboos or woods or a mixture of the bamboos and woods are mixed with glue and placed into a mould to be pressed into a molding board core with holes, each section profile of the holes is round or square or rectangular or irregular shaped, and the holes can be either communicated up and down or not. As the molding board core with the holes are pressed by mixture of glue and the powder or the thread or the strip or the sheet materials made of the dried bamboos or the woods or the mixture of the bamboos and the woods, discarded bamboos and woods can be recycled, resources are saved and cost is lowered; moulding process is simple; further, resistance to inflation, deformation and shock of the board core is strengthened due to arrangement of the holes; and effect of soundproof is provided when the board core is used in a composite floor.
Description
Technical field
The utility model relates to a kind of plate core with sound insulation, resistance to deformation.
Background technology
Traditional composite floor board is by thickness of slab direction stacked be bonded of polylith veneer along composite floor board, insufficient strength due to veneer (plate core), anti-expansion, non-deformability are poor, this composite floor board easily produces to stick up and becomes and be full of cracks, and when producing in order to control the straightness accuracy of blank, complex process is and loaded down with trivial details, and in addition, general composite floor board soundproof effect is poor.
Summary of the invention
The utility model provides a kind of plate core, has solved in the prior art the poor problem of anti-expansion, non-deformability of veneer in composite floor board.
The technical scheme of this central layer is: a kind of plate core, it is to put into by the powdery of the bamboo of drying or wood or thread or strip or flaky substance the pertusate profiled sheeting core of being with that mould inner pressure system forms after mixing glue.
As preferably, the cross sectional shape of described hole is circle or square or rectangular or irregular shape.
As preferably, described hole communicates up and down.
As preferably, described hole does not communicate up and down.
The beneficial effects of the utility model are: compacting forms after mixing glue is with pertusate profiled sheeting core by powdery that the bamboo of drying or wood or bamboo wood are mixed or thread or strip or flaky substance, not only discarded bamboo and wood waste material can be re-used, economize on resources, reduce costs, and moulding process is simple, in addition, due to the setting of hole, make anti-expansion, resistance to deformation, the shock resistance grow of plate core, and use has soundproof effect on composite floor board.
Description of drawings
Fig. 1: the structural representation of the utility model plate core;
1-profiled sheeting core, the 2-hole.
The specific embodiment
As shown in Figure 1, a kind of plate core, it is by powdery or thread or strip or the flaky raw material of the bamboo of drying or wood or the mixing of bamboo wood, puts into the profiled sheeting core 1 with hole 2 that mould one-shot forming compacting forms after mixing glue, wherein:
The glue that adopts is water soluble urea formaldehyde glue, also can replace with polyvinyl acetate glue or phenol glue or melamine urea-formaldehyde glue, perhaps mix to replace with wherein two or more glue, be perhaps main component with above-mentioned several glue, modified glue after the interpolation auxiliary agent replaces, and selects concentration and the applied amount of glue and glue thereof according to the needs of producing.
The shape of hole 2 is to have mould to determine, if mould is provided with cylindrical projections, hole cross sectional shape on corresponding profiled sheeting core 1 is circular, if mould is provided with square protrusions, the hole cross sectional shape on corresponding profiled sheeting core 1 is square, and hole 2 can communicate up and down, can not communicate up and down yet, the setting of hole 2 has not only alleviated the weight of plate core, has increased the non-deformability of plate core, and use also has soundproof effect on composite floor board.
The production procedure of the utility model plate core is: will mix the bamboo of glue or powdery or thread or strip or the flaky raw material of wood or the mixing of bamboo wood; raw material consumption according to the central layer that designs in advance; after accurately weighing; join in mould, then will fill raw-material mould put in hot press hot-forming, finally demould health 3～5 days; namely obtain the profiled sheeting core 1 of hole 2; technique is simple, and cost is low, can realize large-scale industrial production.
Claims (4)
1. plate core is characterized in that: it is to put into by the powdery of the bamboo of drying or wood or thread or strip or flaky substance the pertusate profiled sheeting core of being with that mould inner pressure system forms after mixing glue.
2. a kind of plate core according to claim 1, it is characterized in that: the cross sectional shape of described hole is circle or square or rectangular or irregular shape.
3. a kind of plate core according to claim 1 and 2, it is characterized in that: described hole communicates up and down.
4. a kind of plate core according to claim 1 and 2, it is characterized in that: described hole does not communicate up and down.
