Abstract
The invention relates to processing technique for ornament material and building laminated fine wood board. It adjusted the adhesive to apply on the twister, sprayer, then delivering the wood fiber to be twisted and sprayed, spreading the wood fiber for cold pressing, then hot pressing, trimming, sand polishing to get the fiber board. The laminated wood board is moisture proof, water proof, durable and good in stability.
Description
Technical field
The present invention relates to the manufacture technology field of finishing material and building materials fiberboard, especially a kind of formaldehyde-less fiber board that does not have free formaldehyde release and preparation method thereof.
Background technology
Along with the raising of people's living standard, people also have higher requirement to the finishing in its inhabitation or places such as office, activity, not only require elegant in appearance, modish fashion, succinct naturally, but also require health environment-friendly.Fiberboard is as the most widely used a kind of finishing articles for use and building materials, at common in the market fiberboard, its burst size of methanal major part can reach the GB requirement, and (country put into effect among " formaldehyde in indoor hardware fitting wood-based plate and the goods thereof discharges and limits the quantity of " GB18580-2001 and stipulated calendar year 2001, free formaldehyde release≤1.5mg/L, can be directly used in indoor, the finishing material of free formaldehyde release≤5.0mg/L must just can be used for indoor through facing), but have the release of pest, household, office, finishing material that places such as activity are used or articles for use, as the floor, furniture, wallpaper, smallpox, the timber window, coating or the like, though the release of the nuisance of each product can reach GB and require, but several finishing materials are used in same site space together, the nuisance that discharges has jointly just exceeded GB greatly, and this is with the health of serious threat numerous people.
Summary of the invention
Purpose of the present invention just is formaldehyde-less fiber board that provides at the deficiencies in the prior art part release such as a kind of formaldehydeless venomous injurant such as grade and preparation method thereof.
Formaldehyde-less fiber board provided by the present invention is formed through hot-press solidifying by wood fibre and adhesive, and wherein, the diameter of wood fibre is below 0.5mm, and the content of adhesive is 250～350kg/m
3, wood fibre and adhesive all do not contain formaldehyde.
The preparation method of formaldehyde-less fiber board provided by the present invention comprises the steps:
1. vinylacetate that does not contain formaldehyde and isocyanates are stirred with mixer, standby as adhesive;
2. deployed adhesive is poured on glue mixer or the glue sprayer;
3. the wood fibre that dry finishing is removed formaldehyde well and is delivered to and is carried out glue mixing or spray glue on glue mixer or the glue sprayer;
4. the wood fibre of having mixed glue or having sprayed glue is delivered to mating formation of the enterprising andante base of spreading machine, the slab that paves is delivered to precompressed on the preformer;
5. the good slab of being made up of wood fibre of colding pressing is placed on hot pressing on the hot press.
The fiberboard that adopts said method to make, basically reached formaldehydeless release, therefore improved greatly because of office space, house fitting-up venomous injurant exceed standard and caused the phenomenon of cancer, realize environmental protection and healthy purpose, and this fiberboard also have protection against the tide, waterproof, durable, advantage such as stability is good.
The specific embodiment
The present invention is described in further detail below in conjunction with specific embodiment.
Formaldehyde-less fiber board of the present invention is formed through hot-press solidifying by wood fibre and adhesive, and wherein, the diameter of wood fibre is below 0.5mm, and the content of adhesive is 250～350kg/m
3, as 250kg/m
3, 300kg/m
3, 350kg/m
3Deng being selectable consumption, wood fibre and adhesive all do not contain formaldehyde.
The employed instrument of preparation method of the present invention, equipment are Fibreboard Production equipment (as cold press, hot press, glue mixer, glue sprayer, spreading machine, sander, Sawing machine etc.) commonly used.
Material is any wood fiber of planting, and adhesive is vinylacetate and isocyanates or other no-formaldehyde adhesives or formaldehydeless rubber powder, micelle, adhesive tape.
Concrete technical process is:
1. 1 part of 10 parts of vinylacetates that does not contain formaldehyde and the isocyanates mixer with rotating speed≤500 rev/min is stirred, standby as adhesive; Containing the glue bucket must not be the active metal, but plastic cement bucket or stainless, and in one hour, use up the adhesive that stirs, otherwise, the adhesive that stirs is scrapped.
2. deployed adhesive is poured on glue mixer or the glue sprayer.
3. the wood fibre that dry finishing is removed formaldehyde well and is delivered to and is carried out glue mixing or spray glue on glue mixer or the glue sprayer, and resin added is 300kg/m
3The method of removing formaldehyde be utilize ammonium ion or other formaldehyde catching agents in formaldehyde in the plate remove by modes such as boiling, immersions.
4. the wood fibre of having mixed glue or having sprayed glue is delivered to the mating formation of the enterprising andante base of spreading machine (pavement thickness on require decide), the slab that paves is delivered to (pressure is transferred to 30kg/cm on the cold press
2) precompressed 60 minutes, the size of pressure depends on the requirement of fiberboard density, and high density fiberboard pressure must be transferred to 1200 tons, and the pressure of low-density and medium density fibre board (MDF) then gets final product with the cold press of 600-800 ton.
5. the good slab of being made up of wood fibre of colding pressing is placed on hot pressing on the hot press of pressure 〉=1200 ton, hot pressing pressure 〉=30kg/cm
2, the time is slab thickness mm * 1 minute, temperature is 110-115 ℃.
The formaldehyde of trace distributes thoroughly under this HTHP and long environment already.After the good slab of hot pressing deposited 15 days, sanding amputated the irregular part of plate in four limits, sanding two surfaces, and slab just has been made into fiberboard.
The specification of the fiberboard of making by the method for the invention is rectangle, square, rhombus or irregularly shaped arbitrarily.
