Abstract
The utility model discloses a veneer with electromagnetic shield function, which comprises an upper wood single plate a middle wood single plate and a lower wood single plate. An electricity conductive layer is arranged between the lower surface of the upper wood single plate and the upper surface of the middle wood single plate, and the lower surface of the middle wood single plate and the upper surface of the lower wood single plate. The electricity conductive layer comprises a splicing dose and evenly filled fiber conductive addition material. The electromagnetic shield effectiveness is ranged from 20 db to 25 db, furthermore, the utility model is of simple production and low cost with the intensity and natural vein of plank.
Description
Technical field
The utility model relates to a kind of glued board with electro-magnetic screen function.
Background technology
Along with the continuous development and progress of electronics industry, various electronic equipments are widely used, and the electromagnetic pollution that electromagenetic wave radiation causes has become a kind of new public hazards.This electromagnetic pollution meeting harm humans healthy causes ecological deterioration; Disturb the normal operation of electrical equipment, electronic equipment, bring out various accidents, leak the computer secret.Electromagnetic shielding is an effective means of alleviating electromagnetic pollution.Timber or wood based substrate material are applied to furniture more and more widely, decorate structural material.It is generally acknowledged that timber and pure wood-base fibre and particle panel material belong to the non-conductor of electricity, do not have electromagnet shield effect.
At present, the domestic and international composite wooden material that has occurred having the electromagnetic wave shielding function, the main methods such as chemical plating metal, (cathode) sputtering, stickup thin metal layer (comprising wire netting), high temperature carbonization of using, the technology more complicated is arranged, cost height, secondary pollution, destroy the shortcomings such as native texture of timber itself, the easy oxidation of wire netting contact, conductive capability reduces, and the electromagnet shield effect decay is serious.
The utility model content
At the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of manufacturing simple, cheap, also preserves the intensity of sheet material and the glued board with electro-magnetic screen function of native texture simultaneously.
For achieving the above object, a kind of glued board with electro-magnetic screen function that the utility model provides comprises: go up wood single-plate, middle wood single-plate and following wood single-plate, be respectively arranged with conductive layer between last wood single-plate lower surface and the middle wood single-plate upper surface and between middle wood single-plate lower surface and the following wood single-plate upper surface, this conductive layer adds material by the fiber conduction of bonding agent and evenly filling and forms.
Further, described fiber conductive material is stainless steel fibre and/or brass fiber, and described conduction is added material length and is respectively 3～10 millimeters, and diameter is 30～60 microns.
The utility model glued board, its electromagnet shield effect are 20～25 decibels, and make simply, and be cheap, also preserves the intensity and the native texture of sheet material simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, wherein going up wood single-plate 1, middle wood single-plate 3, descending wood single-plate 4 is by timber, and the flat board of rice straw, wheat straw etc. belongs to prior art.Be respectively arranged with conductive layer 2 between last wood single-plate 1 lower surface and middle wood single-plate 3 upper surfaces and between middle wood single-plate 3 lower surfaces and following wood single-plate 4 upper surfaces, this conductive layer 2 adds material by the fiber conduction of bonding agent and evenly filling and forms.Bonding agent is Lauxite or phenolic resins, and urea aldehyde seeds add an amount of ammonium chloride.Conduction is added material length and is respectively 3～4 millimeters, and 6～7 millimeters, 9～10 millimeters fibrous conductions are added material, and this conduction is added stainless steel fibre, brass fiber that diameter 60 micron or the two the mixture of material for 30 microns of diameters.The stainless steel fibre that diameter is 30 microns accounts for 10～30 grams of every square metre of wooden unit; The brass fiber that diameter is 60 microns accounts for 20～50 grams of every square metre of wooden unit, and perhaps the mixture of the two accounts for 20～30 grams of every square metre of wooden unit.
Veneer flattens through hot pressing and handles, and method is for drying on hot press and flatten veneer, and its technological parameter is 100 ℃ of temperature, and 1 minute time, unit pressure 0.5MPa does not add backing plate.
Glued board is 1 millimeter heat-resisting silicane rubber plate respectively adding a thickness between the hot press backing plate up and down promptly through the flexible thermal compression technology, and its hot pressing parameters is 120 ℃ of hot plate temperatures, pressing time 1min/mm, unit pressure 1MPa.
In sum, the utility model glued board, its electromagnet shield effect are 25～35 decibels, and make simply, and be cheap, also preserves the intensity and the native texture of sheet material simultaneously.
Claims (2)
1. glued board with electro-magnetic screen function, it is characterized in that, comprise: go up wood single-plate, middle wood single-plate and following wood single-plate, be respectively arranged with conductive layer between last wood single-plate lower surface and the middle wood single-plate upper surface and between middle wood single-plate lower surface and the following wood single-plate upper surface, this conductive layer adds material by the fiber conduction of bonding agent and evenly filling and forms.
2. a kind of glued board with electro-magnetic screen function according to claim 1 is characterized in that described fiber conductive material is stainless steel fibre and/or brass fiber, and described conduction is added material length and is respectively 3～10 millimeters, and diameter is 30～60 microns.
