Description
Technical field
This utility model relates to plywood technical field, a kind of formaldehyde-free plywood.
Background technology
Nowadays plywood is the most increasingly liked by people as furniture upholstery, the adhesive that plywood is used
When pasting sheet material, later stage Diazolidinyl Urea, affect health of people.Plywood urea-formaldehyde glue need to add filler, to carry when modulation
Its first viscosity high, prevents glue from too permeating, improves Pre-pressure property.Domestic main employing flour, a small amount of wood powder etc. are as urea aldehyde
The filler of glue, annual needs about 300,000 tons of flour of industry.And the grain yield of China is being faced with significant challenge, every year
Consume so many flour on sheet fabrication, waste great to grain resource beyond doubt.Melmac dipping paper because of
There is the premium properties such as abundant, easy to use, wear-resisting, the shock resistance of style, be widely used in the base such as particieboard, medium density fibre board (MDF)
The veneer of material, manufactures laminated flooring, cabinet, wardrobe etc..During the production and use of dipping paper, can produce substantial amounts of useless
Material and cutting edge clout.Process according to the mode burned, cause the biggest pollution to environment.In melmac dipping paper
Containing cellulose, hemicellulose and Lauxite, Lauxite therein is not fully cured.
Therefore, design the release of a non-toxic formaldehyde-free for overcoming the deficiency of above-mentioned technology, bonding strength is good, reduce money
A kind of formaldehyde-free plywood of source waste, inventor's problem to be solved just.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of formaldehyde-free plywood, its simple in construction,
Non-toxic formaldehyde-free discharges, and bonding strength is good, reduces the wasting of resources.
This utility model solves its technical problem and be the technical scheme is that a kind of formaldehyde-free plywood, and it includes list
Flaggy, urea-formaldehyde resin adhesive packing layer, described ply at least two-layer, by the urea-formaldehyde resin adhesive laid between described ply
Packing layer bonds, and is provided with the dipping paper waste material of the melmac after pulverizing, institute in described urea-formaldehyde resin adhesive packing layer
Stating the ply after bonding overall as sandwich layer, described sandwich layer upper surface is disposed with activated carbon adsorption layer, glass from bottom to up
Glass fibrolamellar, scribbles ultraviolet curable coating, is pasted with incombustible material bottom described sandwich layer above described glass fiberboard
Decoration panel, is provided with activated carbon adsorption layer bottom described sandwich layer and between incombustible material decoration panel.
Further, the incombustible material that described incombustible material decoration panel uses is the one in aluminium foil, Copper Foil or calcium silicate board.
The beneficial effects of the utility model are:
1, the waste and old melmac dipping paper after this utility model will be pulverized substitutes flour as urea-formaldehyde resin adhesive
Filler, in dipping paper, the most completely crued tripolycyanamide has the effect of formaldehyde catching, can after therefore adding urea-formaldehyde resin adhesive to
To reduce the release of formaldehyde, the recycling problem of waste paper can be solved, it is possible to reduce impregnation cost, but also product can be improved
Bonding strength.The sandwich layer both sides formed by gluing at the above lamina of at least two-layer are equipped with side activated carbon adsorption respectively
Layer, activated carbon can adsorb the formaldehyde of plywood release, it is ensured that plate safety is nontoxic.Glass layer can strengthen the strong of plywood
Degree, one layer of incombustible material decoration panel that plywood base is arranged, there is flame retardant effect, ultraviolet curable coating can improve plywood
The glossiness on surface and scraping and wiping resistance performance, the surface of protection plywood.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Description of reference numerals: 1-incombustible material decoration panel；2-activated carbon adsorption layer；3-ply；4-urea-formaldehyde resin adhesive is filled out
The bed of material；5-glass fiberboard；6-ultraviolet curable coating.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further, it should be appreciated that these embodiments are merely to illustrate this
Utility model rather than limit scope of the present utility model.In addition, it is to be understood that reading the content that this utility model is lectured
Afterwards, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values also fall within application
Appended claims limited range.
Seeing Fig. 1 is this utility model structural representation, and this structure one formaldehyde-free plywood, it includes ply 3, urea
Urea formaldehyde glue packing layer 4, ply 3 at least two-layer, between ply 3, the urea-formaldehyde resin adhesive packing layer 4 by laying is carried out
Bonding, is provided with the dipping paper waste material of the melmac after pulverizing, the ply 3 after bonding in urea-formaldehyde resin adhesive packing layer 4
Overall as sandwich layer, sandwich layer upper surface is disposed with activated carbon adsorption layer 2, glass fiberboard 5, glass fibre from bottom to up
Scribble ultraviolet curable coating 6 above flaggy 5, bottom sandwich layer, be pasted with incombustible material decoration panel 1, bottom sandwich layer and incombustible material
Being provided with activated carbon adsorption layer 2 between decoration panel 1, the incombustible material that incombustible material decoration panel 1 uses is aluminium foil, Copper Foil or silicic acid
One in calcium plate.
Waste and old melmac dipping paper after pulverizing substitutes the flour filler as urea-formaldehyde resin adhesive, in dipping paper
The most completely crued tripolycyanamide has the effect of formaldehyde catching, can reduce releasing of formaldehyde after therefore adding urea-formaldehyde resin adhesive to
Put, the recycling problem of waste paper can be solved, it is possible to reduce impregnation cost.In dipping paper powder containing a certain amount of methylol and
Amino isoreactivity functional group, can participate in the curing reaction of urea-formaldehyde resin adhesive, and form crosslinking space structure therewith and solidify, because of
This can improve the curing performance of urea-formaldehyde resin adhesive, improves the bonding strength of product.When single use melamine impregnated paper powder
End, when its consumption accounts for the 10%～15% of resin quality, the bonding strength of plywood is the highest.Pass through at the above lamina of at least two-layer
The glued sandwich layer both sides formed are equipped with side activated carbon adsorption layer 2 respectively, and activated carbon can adsorb the formaldehyde of plywood release,
Ensure that plate safety is nontoxic.Glass layer can strengthen the intensity of plywood, one layer of incombustible material decorations that plywood base is arranged
Panel 1, has flame retardant effect, and ultraviolet curable coating 6 can improve glossiness and the scraping and wiping resistance performance of face veneer, protects glue
The surface of plywood.
