Abstract
Twig sandwiched fibre board and preparation method, its intermediate layer is to arrange as far as possible neatly branch closely, and the woody debris that is mixed with resin glue is filled in the gap of branch and at upper and lower surface and forms interlayer, and its preparation method is that good-for-nothing tree bar is done, being regardless of the length cut-off blocks, be arranged in the interlayer plywood hot-pressing technological forming routinely, described wood-based plate, timber resources utilization rate height, cost is low, and the presentation quality of production board can be identical with glued board, and the physical property of sheet material is near log.
Description
The present invention relates to artificial board, particularly twig sandwiched fibre board and preparation method thereof.
Existing wood-based plate mainly contains glued board, particieboard, fiberboard.The raw material of glued board is that log is peeled into thin plate after boiling is handled, and pastes pressurization and forms glued board.It must use the log of becoming a useful person, and can not utilize more carefully and not straight branch is done, and timber resources consumption is big.The timber resources utilization rate of particieboard and fiberboard is higher, but timber is processed into wood shavings, wood chip or wood-fibred, the material-structure of timber is fully destroyed, it mainly reorganizes plate construction, the texture of its production board, MOR by binding agent, pressurization, elasticity is all very poor, it is bad to hold nail power, and glue consumption is many, than great.
The present invention's purpose is to provide a kind of timber resources utilization rate height, and the physical property of sheet material is near twig sandwiched fibre board of log character and preparation method thereof.
Described twig sandwiched fibre board, its intermediate layer is to arrange as far as possible neatly, be regardless of closely length, but straight substantially branch (or woodenware processing give up strip leftover pieces or bamboo different slight), the woody debris of being stirred by thermosetting resin glue is filled in the gap of each branch, and forms interlayer at the upper and lower faces in intermediate layer.
Woody debris can be the used wood shavings of conventional particieboard, wood chip, also can be the used wood fibre of fiberboard.
Can cover the high-quality panel of beautiful texture on the interlayer of upper and lower faces.
The preparation method of described twig sandwiched fibre board is:
A gets the raw materials ready:
(a) good-for-nothing branch is done to be principle substantially directly, be regardless of length, transversely truncation;
(b) multiple blade saw that constitutes with fixing side by side a plurality of saw blades on the axle will vertically be cut by brachymemma and straight substantially branch, and the spacing of each saw blade of multiple blade saw can be regulated according to the thickness of production board.If can be cut into more than two by the spacing of its diameter of the branch of ripping greater than saw blade, if its diameter can pass the saw blade gap less than the spacing of saw blade and not be cut open, branch is by horizontal, vertical twice sawing, and most of bark peels off, and the bark that peels off is abandoned it;
(c) the dry processing (oven dry, the dried naturally) branch that quilt is cut, dried branch has the part bark to peel off again, abandons it again.The branch that remains a small amount of belt leather needn't be handled again;
(d) the remaining crooked branch of preceding operation, branch are made wood shavings, wood chip or wood fibre and dry the processing with wood chipping equipment or sander;
B: making sheet
(a) shop one deck is mixed with the woody debris of thermosetting resin glue, and it is above through aforementioned processing and sprayed the branch of resin glue to repave one deck, and marshalling is tight as far as possible, repaves the woody debris that is mixed with resin glue, and the space of filling between branch also forms skim;
(b) with the plate plywood hot-pressing technology timing routinely of completing, pressurize, add warm working;
(c) sheet material cutting edge, the sanding of press forming.
By the twig sandwiched fibre board that above-mentioned making sheet operation is made, its appearance tactile impression is as particieboard or fiberboard.
Before making sheet (a) operation, spread the used high-quality log thin plate of conventional glued board earlier, by (a) process operations, repave one deck high-quality log thin plate at last again.
By the sheet material that this technology is made, its appearance tactile impression is identical with the high-quality glued board.
Twig sandwiched fibre board of the present invention and preparation method can use good-for-nothing branch to do in a large number, and a small amount of useless substantially wood shavings, wood chip, and raw material sources are wide, and inexpensive.Use high-quality log thin plate as panel, its presentation quality is identical with the high-quality glued board.But described twig sandwiched plate, the utilization rate of its high-quality log thin plate only account for good-for-nothing branch and do below 1/10th of utilization rate.Do because its main material is a branch, glue consumption lack more than one times than particieboard, and the wood structure of branch destruction not, and the glued board of making is near the physical property of log, and its proportion is littler than particieboard, also near log scale.Because timber resources utilization rate height, raw material is inexpensive, and the product cost of twig sandwiched plate is about 1/4th of high-quality glued board.Also lower than particieboard cost.
Fig. 1 is the sectional drawing of described twig sandwiched fibre board.
Embodiment one,
Sandwich compo board resin bounded plywood, intermediate layer 3 are that two-layer arrangement is neat as far as possible closely and be regardless of length but straight substantially branch, and upper and lower panel 1 is the high-quality veneer.By the woody debris that thermosetting resin glue stirs, it is wood shavings, wood chip, is filled between branch and formation interlayer 3 between intermediate layer and upper and lower panel.
Preparation method:
A gets the raw materials ready:
(a ') is equipped with the required upper and lower panel of conventional glued board 1,
(a) the dried cut-off of good-for-nothing branch is blocked, is regardless of length,
(b) branch that blocks with the multiple blade saw ripping, the saw blade spacing is adjusted into 1/3rd of production board thickness,
(c) the dry processing,
(d) with wood chipping equipment or sander branch wooden fork, the branch of bending are made wood shavings, wood chip, and dry the processing;
B making sheet:
(a) shop one deck prime sheet is a lower panel 1 earlier, spreading wood shavings, the wood chip that skim is mixed with thermosetting resin glue then is interlayer 2, resin glue is identical with conventional particieboard with the proportioning of wood shavings, wood chip, repaving the two-layer branch that sprayed resin glue is intermediate layer 3, repave wood shavings, the wood chip of glue mixing, fill the gap of branch and form short lap 2 on branch, spreading one deck prime sheet at last is top panel 1
(b) will complete plate plywood hot-pressing process forming routinely,
(c) cutting edge, sanding.
Used thermosetting resin glue is pollopas or phenolic resins.
