Abstract
The wooden articles made of timber fiber and resin is produced by the steps of cutting wood stripe, rolling, forming timber fiber, spraying glue, carding, cutting, moulding, pressurizing and heating to cure and form. The resin used includes urea-formaldehyde resin, phenolic resin, melamine resin, etc. The present invention provides a new type of timber product, can produce timber product of different shapes and sizes and expands the application range of timber.
Description
The present invention relates to the new technology of wooden articles of bionical recombined timber fiber bundle.
For replenishing the log resource deficiency, traditional way is to utilize three surplus thing processing and manufacturings such as the rim charge of path wood inferior, fast-growing woods material, wood-processing industry, waste material to become sham wood sheet materials such as particieboard, fiberboard, splicing plate or multilayer composite sheet, but its physical and mechanical property all is inferior to log, so range of application has its limitation.Further develop path wood inferior, fast-growing woods.The evaluation and exploration technology of three surplus things such as the rim charge of material, wood-processing industry, waste material has very big society and economic worth.
The object of the present invention is to provide a kind of new wood fibre bundle that utilizes to make man-made Wood and manufacture method thereof,
The technical solution of timber fiber bundle goods is: the material that constitutes the wood fiber bundle goods is made up of wood fiber bundle and resin.
Its concrete manufacturing step is as follows:
(1) opens bar:, with the die-cut row's cutter of U-shaped juggle is die-cut into batten then with the timber segmentation
(2) kicker: with batten material draw down slabbing timber;
(3) form wood fiber bundle: the tearing of sheet material is become wood fiber bundle, can be wood-fibred one by one, also can be wood-fibred one by one;
(4) spray glue: wood fiber bundle is sprayed resin glue, so that the wood fiber bundle bonding;
(5) combing, push, grind base: even and combing in order through the stand, orientation pushes for the wood fiber bundle that will spray glue, is rolled into cord sheet blank then and carries out precuring;
(6) cut out material, dress mould: the wood fiber bundle blank is cut into tablet by article shape, then tablet is in layer inserted mould, and between every two-layer tablet, add the coating viscosity glue resin;
(7) solidified forming: charged mould is put into the pressurization warming-up device, and with the resin solidification of spraying, timber fiber bundle is configured as goods, then the demoulding.
Dirtier as timber, also can be after above-mentioned (3) form the wood fiber bundle operation, the general labourer's preface of adding up, and drying process, and then enter the spray glue process.
This wood fiber bundle goods only are made up of wood fiber bundle and adhesive resin, and material constitutes simple, are convenient to make.The manufacture method of this wood fiber bundle goods is simple and easy to do, because timber is become wood fiber bundle, bonding with adhesive, can be according to the difformity size of goods, bonding wood-fibred is cut into different tablets, through in mould, solidifying, being shaped, so invent the new timber-work of a class, and can make the goods of difformity and size, enlarged the weedtree range of application.The present invention makes simple and easy.
Below to further specifying.
1, the material that constitutes goods of the present invention is made up of wood fiber bundle and resin, and resin wherein can be a pollopas, also can be phenolic resins, also but melmac or other resin.
2, for this wood fiber bundle product and making method, in its spray glue process, the resin glue of spraying is a pollopas; In the said press setter preface, adding the adhesive resin that is coated with between every two-layer tablet also is pollopas, so that the process conditions unanimity of solidifying, being shaped.
Resin glue in the above-mentioned spraying process also can be a phenolic resins, in the press setter preface, adds the adhesive resin that is coated with between every two-layer tablet and also uses phenolic resins.
Resin glue in the above-mentioned spraying process also can be melamine by resin, in the press setter preface, add the adhesive resin that is coated with between every two-layer tablet and also use melmac.
Except that available above-mentioned three kinds of resins, also can use other appropriate resin in above-mentioned spraying, the press setter preface.
3, further specifying the process in the manufacture method of the present invention:
(1) open bar: use wafer saw with the timber section of being sawn into, it is different and different that every segment length is looked product size, general value in 5～12 centimeters, as make deck plate, desirable 8 centimeters one section.Preferably remove knaur, with U-shaped row cutter juggle is die-cut into batten then, its device therefor or instrument all belong to routine techniques.
(2) kicker: batten is sent into two rollings grind machines, by two rollers batten is rolled and grind that to become thickness be 2～3 millimeters flat-shaped wood chip material; This moment, the fibre structure of timber became loose.
(3) form wood fiber bundle: the two roller tearing machines with having fiberizing drum along with quick rotation, become the wood chip material tearing of draw down the wood fiber bundle of wood-fibred or 0.5～3 millimeter thickness.
(4) spray glue: at room temperature spray tacky resin, spray glue thickness is in 0.2 millimeter.
(5) combing, push, grind base: will spray bakelite material fibre bundle and place on the platform, with the combing cupboard that the wood fiber bundle combing is orderly, utilization is pushed plate and is pushed channel mould the timber fiber bundle orientation is pushed into thickness at 3～8 millimeters cord sheet blank
(6) cutting, dress mould: in the dress mould, at room temperature add between every two-layer tablet and be coated with an amount of adhesive resin.Or curing agent solution.
(7) solidified forming: with hydraulic press mould is heated, the pressure size varies in size generally every square centimeter of 15～30 kilograms of scope values according to goods.It is different and different according to used tacky resin that institute adds the curing temperature and time.In fact, the condition that resin solidification is heated belongs to known technology.Embodiment is as follows:
(1) pollopas:
To grinding the base, precuring is about 30～120 minutes under the room temperature, representative value 80 minutes after spray glue; To mould as pressing 15～30 kilograms every square centimeter, according to the goods size adjustment; 90 ℃～140 ℃ of solidification temperatures, the typical case gets 120 ℃; 10 minutes hardening times.
(2) phenolic resins:
To grinding the base, solidified about 30～120 minutes representative value 80 minutes from spray glue under the room temperature; To touching 15～30 kilograms every square centimeter of tool pressurizations, according to the goods size adjustment; 120 ℃～150 ℃ typical cases of solidification temperature get 130 ℃: 10～15 minutes hardening times, representative value 12 minutes.
(3) melmac:
To grinding the base, solidified about 30～120 minutes representative value 80 minutes from spray glue under the room temperature; To 15～30 kilograms every square centimeter of mould pressurizations, according to the goods size adjustment; 100 ℃～140 ℃ of solidification temperatures, 130 ℃ of representative values; 10～15 minutes hardening times, representative value 12 minutes.
Add the different resin of resin employing that is coated with between the resin that allows the spraying of spray glue process and press setter preface two tablets; this moment is as long as suitably regulate the pressurization condition of heating; and can in goods, give and bury annex and the surface is beautified, this kind situation also belongs to the protection domain of goods of the present invention and manufacture method.
