Description
Technical field
The invention belongs to building material technology, relate to a kind of processing method of ecological board particularly.
Background technology
Timber is the primary raw material in upholstery and building industry; in recent years; countries in the world are because focusing on forest conservation; limit is cut down, is prohibited and cut down prevalence; timber due to supply not enough so that very in short supply; modern society people are more and more higher for the requirement of quality of the life, extremely focus on environmental protection concept, wish that the decorative building material pursuing more environmental protection in furniture design fitment process is improved the quality of living.
Ecological board is also paint free plate, it is most popular a kind of novel dalle on current sheet material market, the paper with different colours or texture is put into melamine resin adehsive stick soak, then certain state of cure is dried to, pasted on particieboard, moist-proof board, medium density fibre board (MDF), glued board, core-board or other hardboards surface, through the decorative panel of hot pressing.The advantage of this sheet material is surfacing, not yielding, bright-colored because the sheet material double face coefficient of expansion is identical, surface is more wear-resisting, corrosion-resistant, price economy.
Ecological board manufacture process final key one step is in the market at high temperature overlay on substrate by melamine impregnated paper mostly, now generally all use cheap, the good urea-formaldehyde glue of anchoring effect sticks agent, this adhesive is the easy formaldehyde remaining free state in sheet material in high temperature environments, thus contaminated environment, application number is disclose a kind of reel melamine faced chipboard and preparation method in the publication application documents of 200410014197.0, it is through high temperature hot pressing one deck melamine impregnated paper wainscot at central layer two side external surface, hot pressing temperature is 180 ~ 200 DEG C.
How to find a kind of ecological board processing method of environmental protection and energy saving, become problem demanding prompt solution.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of processing method of ecological board.
The technical solution used in the present invention is:
A processing method for ecological board, comprises the following steps:
(1) waste and old wood of selection construction site, factory is as raw material, and be sawn into the fillet of wide uniform thickness, fillet, through gluing machine gluing, pieces together central layer;
(2) press on central layer, through high temperature, side pressure debugging, surface is stand-by after scraping greasy, sanding;
(3) plate in pasting after the central layer upper and lower surface gluing after sanding, colds pressing, then refacing at normal temperatures, obtained substrate;
(4) by substrate hot pressing, then greasy, sanding is scraped to substrate surface, stand-by;
(5) after the substrate double spread that sanding is good, paste Recombinant Wood, cold pressing at normal temperatures, then hot pressing, carry out finishing and sanding to plate face after hot pressing, sanding terminates rear cutting edge;
(6) the plate embryo upper and lower surface after cutting edge is coated with glue melamine impregnated paper, and cold pressing at normal temperatures, cutting edge again of colding pressing obtains ecological board.
As preferred technical scheme, in described step (3), the one in poplar or Eucalyptus selected by plate.
As preferred technical scheme, in described step (3), cold-press process requires: normal temperature, pressure 8 ~ 12Mpa, time 40 ~ 60 minutes.
As preferred technical scheme, in described step (4), heat pressing process requires: temperature 120 ~ 140 DEG C, pressure 10 ~ 14Mpa, time 8 ~ 10 minutes.
As preferred technical scheme, in described step (5), cold-press process requires: normal temperature, pressure 8 ~ 12Mpa, time 15 ~ 30 minutes.
As preferred technical scheme, in described step (5), heat pressing process requires: temperature 120 ~ 140 DEG C, pressure 10 ~ 14Mpa, time 8 ~ 10 minutes.
As preferred technical scheme, in described step (6), cold-press process requires: normal temperature, pressure 4 ~ 6Mpa, time 5 ~ 6 hours.
Beneficial effect of the present invention:
(1) ecological board processing method of the present invention energy-conserving and environment-protective, pasting melamine impregnated paper step uses the latex not containing formaldehyde as adhesive, reduce sheet material content of formaldehyde, just can obtain good anchoring effect because latex does not need to carry out hot pressing simultaneously, just can melamine impregnated paper be cemented on sheet material so only need to use normal temperature to cold pressing in the present invention, effective minimizing energy consumption, has saved energy cost.
(2) central layer of the present invention select construction site, factory waste and old wood as raw material, twice laid, save natural resources, in prior art, ecological board production technology determines thick sanding again after plate and central layer hot pressing in upper and lower both sides, the out-of-flatness problem caused due to became uneven between central layer lath is like this unresolved, and substrate and production board are easily occurred, and in plate, became uneven is even, and stress increases, cause yielding problem, and sanding sand removes too many middle plate and causes the middle plate thickness wasting of resources; The inventive method is first high temperature, side pressure debugging after central layer splicing, and greasy, sanding is scraped on surface, and then bonds with middle plate, to solve in prior art in ecological board production because of stress deformation problem that central layer local became uneven causes.
(3), in prior art, be all generally that melamine impregnated paper directly pastes on the substrate layer, product flatness is bad, and the present invention first pastes melamine impregnated paper again by after Recombinant Wood and base plate bonding, and product flatness is high, good stability.
