Abstract
The method for producing water-proof veneer board for building, furniture or decoration features that the traditional plywood production line and equipment are used to make the sheets such as wooden sheets, metal sheets, metal foil, decorative resin plates separately or alternatively bind together by means of hot-fussible adhesives, such as polyethylene film, polypropene film, or PVC film.
Description
The present invention relates to glued board and production method thereof.Promptly a class has wooden or wooden-metal (sheet material or the paper tinsel) structure of water resistance or the compound glued board and the production method thereof of wood-resin class decorative panel.
It is documented that timber can be divided into according to its adhering object difference with adhesive:
The following adhesive of timber/timber: urea-formaldehyde resin, melamine resin class, phenolic resin class, resorcinol resin class, vinyl acetate resin class emulsion, casein glue.
The following adhesive of timber/metal: epoxy resin class, neoprene class.
(Yu Maoxin etc. translate (day) " fine chemicals dictionary " in June, 1994 version, Chemical Industry Press).
In traditional plywood production technology, mostly be to adopt Lauxite to make adhesive, make its curing under the condition of pressurization, heating, the sheet of wood fibre (arborescences such as wood, bamboo, reed) tree is bonded together becomes glued board.The bonding required time of curing in the production process is about about 30 minutes.
The main flow process of traditional production process is as follows:
Timber rotary-cut (film-making material) → sheet material is dried (80-100 ℃, 15 minutes, or according to sheet thickness and water content and decide) → behind the sheet material brush adhesive alternate stacked → pressurize, add heat bonding, hydraulic pressure heat-sealing machine pressure: 30 kg/cm, temperature: 80-120 ℃, the time: 30 minutes → cooling and shaping → depanning deburring → polishing → finished product.
There are following shortcoming in traditional glued board and production technology:
1, it is poor to adopt Lauxite to make traditional glued board resistance to water of adhesive.Because hardening embrittlement after Lauxite solidifies combines also badly with bonding object, the phenomenon of usually coming unglued after bonding object makes moist, is immersed in water.Therefore, the glued board of selling on the open market (comprise homemade with import) is not water-fast, and the water that makes moist will come unglued.
2, urea-formaldehyde resin itself can give out the pernicious gas that makes us very unpleasant.Endanger operating personnel's health in process of production, glued board deposit with use in, also can give out this pernicious gas.
3, the bonding required time of the curing of production process needs about 30 minutes approximately.Therefore just go out a mould glued board half an hour in actual production.
4, the phenomenon of usually coming unglued after resin class decoration veneer makes moist, is immersed in water.
The objective of the invention is to utilize traditional plywood production streamline and equipment, only its operating process is changed slightly, and seek a kind of hot-melt adhesive wooden sheet, or wood materials and metal (aluminium, iron, stainless steel, copper etc.) sheet material (or metal foil) or wood materials and resin class decorative panel compression heat sealing become the compound glued board of wooden plywood, wood-metal or the wood-resin class decorative board structure with water resistance.
The present invention reaches by following measure:
Adopt hot-melt adhesive-polyethylene, polypropylene or polychloroethylene film raw material as adhesive in the plywood production.
The temperature of hydraulic pressure heat-sealing machine is 130-145 ℃ in the heat seal process.
Technical process of the present invention does not have too big difference with traditional production process, and technological process is as follows:
Timber rotary-cut (film-making material) → sheet material is dried (80-100 ℃, 15 minutes) → sheet material is alternate with polyethylene, polypropylene or polychloroethylene film stacked, the thickness of hot-melt adhesive film such as the thickness of plastic film for agricultural use are then suitable, it evenly is tiled on the wood sheet → pressurize, add heat bonding, the hydraulic pressure heat-sealing machine adopts pressure: 30 kg/cm, temperature: 130-145 ℃, the time: 3 minutes → cooling and shaping → depanning deburring → Throwing light → finished product.
The concrete implementation step of the present invention following (is example as adhesive with polyethylene):
The film-making material: with timber rotary-cut film-making material machine with timber on demand thickness be processed into sheet material.
Oven dry: at drying chamber with sheet material through 80-100 ℃ of oven dry, 15 minutes (deciding) according to the thickness of sheet material and water content.
Join material: with sheet material and polyethylene film (new and old plastic film for agricultural use all can) alternate stacked (sheet material+film+sheet material+film+sheet material).
Compression heat sealing: be positioned over pressurization in the hydraulic pressure heat-sealing machine, add heat bonding, the hydraulic pressure heat-sealing machine adopts pressure: 30 kg/cm, temperature: 130-145 ℃, time: 3-10 minute.
Sheet material after the heat seal forms finished product with trimmer deburring, the polishing of glued board polishing machine again after the cooling and shaping depanning.
Produce compound glued board and only be and in above technical process, join the material difference:
Art material-metal sheet, timber-metal forming and timber-compound glued boards of type such as resin class decorative panel are: respectively with metal sheet as intermediate layer or both sides skin, metal forming or resin class decorative panel are sticking as a side skin or both sides skin.
Other hot-melt adhesive-polypropylene or polychloroethylene film are used as the raw material of adhesive in the plywood production, and its technology is made adhesive with polyethylene film.
Above hot-melt adhesive also can be used as fibrous plate and Chipboard bonded metal sheet face (two sides) or bonded metal paper tinsel and resin class decorative panel (one or both sides).
Above-mentioned technological process is compared with conventional process flow, and difference is to have replaced " sheet material gluing " process in the conventional process flow with " sheet material and hot-melt adhesive film-stack " process in my technological process, and other technological processes are identical.Only pressurized, heated is solidified bonding temperature and time length difference.Only need 3-10 minute with hot-melt adhesive, and old adhesive is wanted half an hour.Here it is utilizes new adhesive production glued board speed fast, and same equipment staff condition improves output 3-10 down doubly.
Production method of the present invention and the glued board of being produced have following benefit:
1, new glued board resistance to water is very good, up till now till (95,4,28), in water continuous dipping nearly 10 months, still as excellent as before, do not come unglued.It is to exist with solid form at normal temperatures that its reason is moulded adhesive because of hot melt, and it is water insoluble, is not afraid of bubble, adding this class adhesive does not resemble the urea-formaldehyde resin crisp, toughness is relatively good, combines relatively goodly with bonding the elephant, phenomenon such as therefore can long period of soaking do not come unglued in water.
2, this class adhesive not only can be timber-bonding wood materials together, and can be bonded together timber-metal securely.Bonding very firm.After being adhered to it the aluminium sheet of 0.5 millimeters thick in the wooden plywood with polyethylene film, only after the institutional framework of destroying timber itself, could separate aluminium sheet and timber, and bond site can't be separated.Use this class adhesive, can be common wooden plywood and various metallic plate, metal forming is bonded together, and produces the composite plywood of wooden golden structure, has opened up the new purposes of glued board greatly.
3, solidify bonding time weak point: see according to result of the test, make the plywood production adhesive, solidify bonding required time at 3-10 minute with polyethylene film.Solidify short 3-10 of bonding time doubly than urea-formaldehyde resin, can go out a mould glued board in 3-10 minute, under same equipment, the staff condition, the several times of can enhancing productivity.
4, hot-melt adhesive nonhazardous such as polyethylene film.In the production operation process, product is deposited and is not produced any pernicious gas, environmental sound in the use.
5, with hot-melt adhesives such as polyethylene films, cost hangs down about 50% approximately than urea-formaldehyde resin.
In heat-fusible adhesive, the same adhesive that can be used as water-resistant plywood production of polypropylene, polyvinyl chloride and polyethylene.
6, can make full use of old polyethylene film discarded in the industrial and agricultural production, accomplish twice laid, for country is that society economizes on resources, reduce of the pollution of waste and old plastic film to environment.
