During the semi-drying process, different material is adopted based on different use, and the produce process includes spraying adhesive, spreading, pressing, and other steps. The spread layers include middle reinforcing rib layer, coarse material layers and fine material layers on two sides. The adhesive is polymer adhesive of dialdehyde starch, protein complex or water soluble polymer resin. The present invention has the advantages of short production period, high strength, low cost and no environmental pollution.
Description
Technical field
The present invention relates to a kind of processing method of bionic reinforced plate, it belongs to the crop stalk is the technology of main material production processing non-wood sheet material.
Background technology
Chinese patent CN1031959A discloses a kind of " artificial composite plank and manufacture method thereof ", it mainly is made up of vegetalitas material, inorganic mineral material and adhesive etc., comprising coarse fodder layer and fines layer, or contain reinforcement again, used binding agent is the rare and modified urea-formaldehyde resin glue of glutinous rice.Its processing method belongs to wet method, and being about to needs through adding the processing step that alkali boils and boils after material is pulverized.The shortcoming of wet method processing is that water consumption is big, contaminated environment.
Summary of the invention
Technical problem to be solved by this invention provides a kind of saving of labor of having, saves time, material-saving, the product strength height, and cost is low, and is free from environmental pollution, the processing method of the broad-spectrum bionic reinforced plate of product processed.
The technical solution adopted for the present invention to solve the technical problems:
The present invention adopts semidry method, chooses the blank of different classes of, different size and structure according to the purposes of finished product, and after the atomization applying glue, adopt and mat formation with station or flowing water dystopy, compression moulding, its concrete technology is as follows:
(1) preparation of various blanks
A, coarse fodder
Crop stalk pressed remove the stalks of rice, wheat, etc. after splitting, have stalks of rice, wheat, etc. straw to press to split, be cut into the long coarse fodder of 2-5cm then, perhaps pressure is split, gone the straw after the stalks of rice, wheat, etc. directly to rub into coarse fodder through kneading machine;
B, fines
It is 30-50 purpose fines that above-mentioned coarse fodder is made granularity through material grinder;
C, reinforcement material
Reinforcement material is removed the stalks of rice, wheat, etc., cuts choosing after pressure splits, has stalks of rice, wheat, etc. straw to press to split, make the bar shaped muscle or through kink, be woven into netted muscle, handle through dipping or glass tempering again;
(2) plate blank paving
In the slab process of mating formation, adopt the atomizing spray glue limit, blank limit of different size to mat formation, also successively give pressure, its concrete technology is as follows:
When adopting coordination to mat formation, in same mould, mat formation according to fines layer, coarse fodder layer, reinforcement layer, coarse fodder layer, fines layer successively from bottom to top, in the pavement process of each fines and coarse fodder layer, adopt atomizing applying glue mode, promptly spray into the glue of spray pattern from the spray Jiao Kou of reinforced applying glue hopper lower end;
(3) compression moulding
Slab is through giving pressure, hot-forming.
Described reinforcement material is selected bamboo, reed, cotton stalk, the twigs of the chaste tree, withy, sorghum stalks, sunflower bar, kudzu, the waning day, crudefiber crop, Ma Liancao and packing for use, is tied up, in the wrapping plastic tape, rope, net one or more.
Described atomizing applying glue mode is feed bin boiling process or negative pressure spraying method, and resin added is the 1.5-3% of billet weight.
Described glue adopts dialdehyde starch, protein complex, or the polymer-binder of selecting the water soluble polymer process of resin to become.
Described coarse fodder layer is divided into half thick layer and more coarse layer again, and the length of half thick layer blank is 2-3cm, and the length of more coarse layer blank is 3-5cm, and more coarse layer is positioned at the both sides of reinforcement layer.
Also use the atomization wax spray when mating formation the fines layer simultaneously, the wax spray amount is the 1-3% of billet weight.
It is single to the invention has the beneficial effects as follows that it has overcome general wood-based plate materials, the drawback that raw material specification is single, thereby improve the intensity of product, and have the saving of labor, save time, material-saving, low, free from environmental pollution, the broad-spectrum characteristics of cost.
The specific embodiment
Embodiment 1: processing has the method for the bionic reinforced plate of 5 layers of structure:
(1) preparation of various blanks
A, coarse fodder
The stalks of rice, wheat, etc. is split, gone to the straw pressure of corn or Chinese sorghum or sunflower crop, be cut into the coarse fodder of 2-5cm then with pulverizer.
B, fines
It is 30-50 purpose fines that above-mentioned coarse fodder is made granularity through flour mill.
C, reinforcement material
Bamboo or reed pressed split the back and cut choosing, make the bar shaped muscle or through kink, be woven into netted muscle, handle through dipping or glass tempering again.
(2) plate blank paving
In the same mould, successively fines, coarse fodder are spread in the mould through reinforced applying glue funnel earlier, side layer limit spray glue (can reduce resin added so in right amount, and it is even to reach applying glue, reduce environmental pollution), glue sprays into the glue of spray pattern from the spray Jiao Kou of reinforced applying glue funnel lower end, and resin added is the 1.5-3% of the weight of blank, described glue adopts the complex compound of dialdehyde starch, albumen, or the polymeric binder of selecting the water soluble polymer process of resin to become.So both made finished product obtain enough adhesion strengths, avoided the harm of formaldehyde in the phenolic adhesive again, pollution abatement, protection production environment and practitioner's physical and mental health.
And then good netted muscle or the bar shaped muscle of the above-mentioned braiding of mating formation.
Afterwards, mat formation successively again coarse fodder layer and fines layer, its method is identical with top described method for paving.
When mating formation upper and lower fines layer, in applying glue, spray the wax of spray pattern, the wax spray amount is the 1-3% of billet weight.
(3) compression moulding
Slab is given pressure earlier, the hot repressing moulding.
(4) again through heat treatment, the cutting edge integer.
Embodiment 2: processing has the method for the bionic reinforced plate of 7 layers of structure:
Its 7 layers are respectively: middle is the reinforcement layer, and the both sides of reinforcement layer are followed successively by more coarse layer, half thick layer, fines layer respectively.
What its processing method and example 1 were different is: its more coarse layer bamboo is that raw material is processed into the blank that length is 3-5cm, it is that raw material is processed into the blank that length is 2-3cm that half thick layer is selected reed for use, the fines layer selects for use corn stalk to be processed into blank, and the material selection wicker of reinforcement layer is processed into netted muscle.
The sheet material that is processed into by embodiment 2 is applicable to the place higher to requirement of strength.
The sheet material that utilizes the present invention to process has following technical indicator: density (unit weight) 0.4g/cm
3～0.8g/cm
