Description
Technical field
The present invention relates to sheet material manufacturing technology field, specifically a kind of production method of no binder densified straw board.
Background technology
Density board is also referred to as fiberboard, be using wood fibre or other plant fiber as raw material, apply urea-formaldehyde resin adhesive or its
Sheet material made of his adhesive, such sheet material can discharge substantial amounts of formaldehyde and be detrimental to health, and recycling is difficult, and useless
After abandoning can not natural degradation, increase social environment harm, fiberboard on the market is this all using trees brush wood as raw material now
Material cost price is low；But timber growth cycle is grown, timber supply amount is reduced year by year；Timber is directly whittled into piece by wood chipping equipment
Shape, fiber fines shape is then twisted into by thread rolling machine, mixing addition urea-formaldehyde glue, is then uniformly paved into tabular during thread rolling
It is hot-forming by hot press.Such fiberboard poor toughness, low intensity, used for disposable high-speed highway.It is near several in addition
Wheat straw waste is directly ground into 1cm or so length by year in the market appearance, is uniformly layered on plate paver by glue spraying in layer
Wheat straw is bonded into sheet material, such sheet material discharges a large amount of formaldehyde, and such plate can not be referred to as fiberboard.
The content of the invention
It is an object of the invention to provide a kind of nonpoisonous and tasteless, formaldehydeless, the low no binder densified straw board of cost
Production method, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical scheme：
