Abstract
An artificial board suitable for building, furniture and package is made up of adhesive and tobacco stem as leftover after flue curing tobacco leaves through chemically processing tobacco stem, rolling press, drying, adding adhesive (13-15%), prepressing for spreading it, hot pressing at 110-130 deg.C and 2-5 MPa for shaping and cutting to the required sizes. It features high strength, resisting worm-eating, and low cost.
Description
The invention belongs to a kind of artificial board and preparation technology thereof who makes with offal, this sheet material is applicable to as building and furniture with sheet material or packaging material.
At present, the artificial board overwhelming majority is that the wood fragments material processes, but China's timber resources is limited, and raw material is well sold and in short supply, the cost height; So developed the artificial board of non-wood material in recent years both at home and abroad again, as making wood-based plate with falx straw, cotton stalk, cornstalk, bagasse, rice bar, straw, sunflower bar, with these manufacture of materials technological requirement height, the timber intensity of manufacturing is low, and purposes is little; Also useful tobacco rod and tobacco stem leather are made wood-based plate (patent publication No. CN1032636A and CN1061554A).Tobacco rod will be purchased in tobacco ground at short notice by season every year, needs the large tracts of land storehouse reservation, and the circulating fund holding time is long, and transit link is many, the suitability for industrialized production difficulty.
The objective of the invention is in order to make full use of cigar mill's waste material---remaining offal (being the petiole and the part vein of tobacco leaf) after the tobacco redrying throwing, make intensity height, artificial board that cost is low.
Another object of the present invention is for a kind of preparation technology who makes this artificial board made of tobacco stalks is provided.
The present invention be achieved in that with after the redried leaf tobacco throwing remaining waste material offal through chemical treatment, remove tar and small part nicotine in the offal, offal after will handling with the method for roll extrusion is rolled into fiber, oven dry again is equipped with binding agent hot pressing by the 13-15% of fibre weight and forms wood-based plate.
Accompanying drawing is a process chart of the present invention, and its preparation process is described in detail as follows:
1. at first offal remaining after the redried leaf tobacco throwing is carried out chemical treatment: with fermentation vat Include the 1-3%NaOH aqueous solution and be heated to 60 ℃～80 ℃, put into then offal and soak 2 Hour removing tar and the small part nicotine in the offal, because of tar to plate in the later hot pressing The bonding of material has a great impact.
2. roll extrusion: from fermentation vat, take out offal and put into roller press, offal is rolled into fiber, And press and remove part moisture content.
3. dry: fiber is put into drying machine carry out drying, baking temperature is 60-100 ℃, Fiber moisture is controlled at below 8%. Excess Temperature can be burned, crosses low dry oversize with the time.
4. applying glue: the 13-15% applying glue of tobacco stalk fibre weight is pressed in dry back in glue mixer, and glue mixing requires evenly.Bonding agent can adopt resinoid, cold setting cement, water emulsion adhesive, preferably adopts resin binder, and wherein homemade urea-formaldehyde resin adhesive price is hanged down and can be satisfied the requirement of sheet material bond quality again.
5. precompressed is mated formation: the raw material after the applying glue is put into extruder carry out precompressed (thickness can be regulated extruder outlet and decide); The central layer of pre-molding is put on the backing plate that paves bottom, and become blanket at central layer upper berth upper layer.Bottom and surface layer are the tobacco stalk fibre of pulverize.
6. hot pressing: the slab that has the bottom backing plate that will pave is sent into and is carried out 110-130 ℃ of hot pressing hot pressing temperature in the hot press, and pressure is 2-5MPa, time 5-15 minute, decides on the thickness of plate.Hot pressing back layer, central layer and bottom are bonded to ganoid whole wood-based plate.
7. cutting edge is put in storage: hot-forming sheet material is pressed required size cutting edge warehouse-in.
Wood-based plate of the present invention has that quality is good, intensity is high, anti-advantage of damaging by worms; And do not need flaking, and to chip, technology is simple; Raw material sources foot, concentrated is collected easily low price.
