Abstract
The utility model provides a composite veneer, comprising a panel, a core plate and a base plate. The panel and the base plate are made of wooden veneers, the core plate is made of magnesite plate, and the core plate is glued with the panel and the base plate. The composite veneer of the utility model has strong fireproof performance, high intensity, good nail engaging force, and small variation coefficient, and can be sawed, nailed and planed. The utility model can be widely used in multiple fields such as package industry, house decoration building industry and transportation industry.
Description
Technical field
The utility model relates to a kind of composite plywood.
Background technology
Wood-based plate comprises magnesite board, wooden boards etc., and they have following deficiency respectively: magnesite board has good flame retardancy, but easy truncation and frangibility are its weakness that can't overcome.Existing wooden boards such as medium density fibre board (MDF) and particulate sheet material etc. then do not have fire protecting performance, and intensity is not high, flexural deformation easily in the use.
Summary of the invention
The purpose of this utility model is the problems referred to above of existing at wood-based plate, provides a kind of tool fire protecting performance, intensity height, non-frangibility, to sting nail power good, the composite plywood that the coefficient of variation is little.
The purpose of this utility model is achieved in that the utility model comprises panel, central layer and base plate, and described panel, base plate adopt wooden plywood, and described central layer adopts the magnesite plate, and central layer and panel and bottom plate glue lump together.
As preferred version, the wooden plywood in the utility model is formed by two layers or multilayer Wooden veneer gummed, is better than Wooden veneer.As better scheme, two-layer at least Wooden veneer is in length and breadth and arranges in two layers of Wooden veneer or the multilayer Wooden veneer.Wood fibre can form in length and breadth and arrange like this, has solved two big problems: be the unfilled corner problem that has solved composite plywood 1,, be difficult for wane when being hit; 2, strengthened the transverse toughness of composite plywood, the stressed easy fractures not in four sides.
As preferred version, adopt the marine glue gummed to form between two layers or multilayer Wooden veneer of the wooden plywood in the utility model.The utility model composite plywood has waterproof, fire prevention dual-use function like this.
Magnesite plate in the utility model adopts the magnesite veneer, and the magnesite plate also claims glass magnesium plate or magnesium oxide plate.
Magnesite plate in the utility model can also be the lightweight magnesite veneer that the magnesite material in the sheet material forms by the foaming of magnesite blowing agent.The utility model becomes the lightweight composite plywood of light sound-proof like this.
Production method of the present utility model is as follows: 1, the magnesite plate adopts existing magnesite board production equipment and technology to produce; When 2, wooden plywood was made up of two layers or multilayer Wooden veneer, applying glue between Wooden veneer adopted hot press hot-forming; 3, carry out cramping after the magnesite plate applying glue with the wooden plywood of panel and base plate and central layer and paste, can select the hot press moulding for use or select for use cold pressing glue to pass through the cold press moulding; 4, carrying out deburring cuts out and promptly gets composite plywood of the present utility model.
Technique effect of the present utility model is:
1, this glued board has fire line, and its fire protecting performance is the incomparable advantage of other wood-base fibre and particle panel material.
2, be difficult for truncation, easily truncation is the weakness that single magnesite fire-proof board can't overcome.
3, can saw, can follow closely, can dig, it is good to sting nail power, easily processing, easily with the other materials stickup, the coefficient of variation is little, the intensity height can flexural deformation in the use.Be better than medium density fibre board (MDF) and particulate sheet material in the wood-based plate greatly.
4, can be according to different needs combinations produce out-of-plane plate, special-shaped plate.
5, can foam by the magnesite blowing agent to the magnesite material in the central layer according to market demand, become lightweight magnesite central layer becomes the sound insulation of lightweight again through cramping " lightweight composite plywood ".
If 6 select for use marine glue hot-forming during to wooden plywood's moulding, can also produce have waterproof, " composite plywood " of fire prevention dual-use function, use very extensive.
The utility model can be widely used in a plurality of fields such as packing business, house ornamentation building industry, transportation.In packing business, be mainly used in and make packing case, pallet etc.; In building industry, be mainly used in metope, roofing and flooring cladding plate; In the furniture manufacturing, be used for various carrier structure plates etc.
Description of drawings
Fig. 1 is the drawing in side sectional elevation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1, the composite plywood of present embodiment is made up of panel 1, central layer 2 and base plate 3, panel 1, base plate 3 all adopt wooden plywood, wooden plywood in the present embodiment is made up of three layers of Wooden veneer, three layers of Wooden veneer are alternately arranged in length and breadth according to the direction of wood fibre, three layers of Wooden veneer are bonded together by glue, and central layer adopts the magnesite plate, and central layer and panel, central layer and base plate are bonded together by glue respectively.
The production method of present embodiment is as follows:
1, the magnesite plate adopts existing magnesite board production equipment and technology to produce.For example, with magnesia is Binder Materials, chlorine water (being magnesium chloride) is a blending agents, medium-alkali glass fiber cloth and nonwoven are tensile materials, mixing perlite, sawdust or being crushed to the rice husk or the wheat straw that are equivalent to the sawdust fineness is inserts, adds to have anti-water, toughness reinforcing, ageing-resistant, as to improve coefficient of softing additive (if foaming needs to add blowing agent), through stirring, rolling, cutting and the magnesite plate.
2, the production of wooden plywood: applying glue between three layers of Wooden veneer, adopt hot press hot-forming.
3, paste carrying out cramping after the wooden plywood of panel and base plate and the magnesite plate applying glue as central layer.Select the hot press moulding for use or select for use cold pressing glue to pass through the cold press moulding.
4, carrying out deburring then cuts out and promptly gets composite plywood of the present utility model.
Composite plywood leftover bits of shearing out and the waste and old composite plywood that in the future reclaims can be pulverized fine inserts as central layer in the new composite plywood by pulverizer, thereby can constantly recycle.
Adopting composite plywood of the present utility model, can reduce the felling of forest, played " Dai Mu " effect, also reduced free formaldehyde release in the house ornamentation simultaneously, overcome a lot of defectives in other wood-based plate, is a kind of quite desirable novel artificial plate.
The wooden plywood that panel, base plate adopted in the utility model can be formed by two layers or multilayer Wooden veneer gummed.Have at least the arrangement in length and breadth of two-layer employing wood fibre better between the multilayer Wooden veneer.
