Abstract
The utility model relates to a mould pressing composite plywood, and small holes are arranged on a single sheet of a thin plywood. The utility model comprises a core plate, an outer layer veneer and adhesive layers arranged among each layer, wherein, the core plate is compounded by a metal net and the single sheet of the thin plywood. The utility model is characterized in that the core board is provided with at least one layer of single sheet of the thin plywood, which is provided with holes. The mould pressing composite plywood has the advantages of simple structure, practicality and low process cost. When temperature and humidity has great variation, the problems of dilatancy and deformation of the mould pressing composite plywood and thereof finished products because of different physical property of the single sheet of the thin plywood of each layer can be prevented.
Description
The utility model relates to a kind of mold pressing composite plywood, particularly a kind of mold pressing composite plywood that is provided with aperture on gummed thin plate monolithic.
Existing mold pressing composite plywood mainly contains two kinds: a kind of is that veneer sheet material by multilayer becomes the composite multi-layer plate through pressurized adhesion; Another kind is to be composite plywood by the central layer that is provided with wire netting, outer obedient panel and adhesive linkage through the HTHP compression molding.A kind of decoration that is mainly used in making door-plate or building in back, smooth attractive in appearance having relatively high expectations to its intensity and outward appearance, but because the gummed thin plate monolithic that uses when manufacturing central layer is a timber of taking from different seeds, different tree order and different dry humidity, its physical property has nothing in common with each other, therefore after the MULTILAYER COMPOSITE moulding, can produce dilatancy along with the variation of serviceability temperature and humidity, and then influence the quality and the outward appearance of product.
The purpose of this utility model is to provide a kind of mold pressing composite plywood that is provided with aperture on gummed thin plate monolithic, to solve owing to the different problems that cause mold pressing composite plywood or the swollen distortion of rising of its manufactured goods of each layer gummed thin plate monolithic physical property.
The purpose of this utility model is achieved in that described mold pressing composite plywood, comprise: central layer, outer thick china and be located at adhesive linkage between each layer, wherein central layer is wire netting and the compound formation of gummed thin plate monolithic, and it is characterized in that: central layer contains the gummed thin plate monolithic that one deck is provided with aperture at least.
Advantage of the present utility model is: simple in structure, practical, processing cost is low; Can prevent because temperature, humidity when bigger variations arranged, because each layer glues together the problems that thin plate monolithic physical property difference causes mold pressing composite plywood or its manufactured goods dilatancy.
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the structural representation of the utility model embodiment
Fig. 2 is the structural representation of gummed thin plate monolithic among the utility model embodiment
Above-mentioned mold pressing composite plywood, comprise: central layer (1), outer thick china (2) and be located at adhesive linkage (3) between each layer, wherein central layer (1) is wire netting (12) and three layers of compound formation of gummed thin plate monolithic that is provided with aperture (15), it is provided with bottom gummed thin plate monolithic (11), is provided with wire netting (12), intermediate layer gummed thin plate monolithic (13) and upper strata gummed thin plate monolithic (14) on it in regular turn; Aperture (15) is uniformly distributed on each layer gummed thin plate monolithic, be equivalent to the glued board monolithic is carried out lax processing, to remove its internal stress, prevent the sheet material dilatancy, above-mentioned bottom gummed thin plate monolithic (11), intermediate layer gummed thin plate monolithic (13) and upper strata gummed thin plate monolithic (14) all are arranged to be mutually the structure that 20-60 degree angle intersection is placed by its wood grain trend; Above-mentioned wire netting (12) can adopt A3 steel, 65Mn spring steel, and No. 45 medium carbon steel, No. 30 or No. 20 materials such as mild steel are made netted; Outer obedient panel (2) is a flame-retardant panel, can make glued board have fire-retardant effect, increases security performance.
