Abstract
The preparation method of bamboo fiber composite board of the present invention adopts bamboo fibre to mix with shell, improve the fire-retardant of sheet material and fire resistance, and adopt single interlayer original slurry material proportioning, integrated formed structure, have structural strength high, make simple, fire prevention, waterproof, Anti-moth-eating, density good, firm, can not absciss layer, flexibility function admirable, the advantage in melamine face can be pasted.
Description
Technical field:
The present invention relates to preparation method of a kind of Novel bamboo fiber composite plate and products thereof, refer to a kind of preparation method bamboo fibre, shell, macromolecule glue, waterproofing wood agent be produced in bamboo fiber composite board especially.
Background technology:
As everyone knows, the present increasing new material of progress along with society is in the sight of people, vermiculite power, string, macromolecule glue, wooden skin have also received the extensive concern of people now as a kind of material of composite plate, a kind of hydrate of vermiculite power, in block, sheet with granular, be the product of the natural minerals weathering alterations such as biotite, feature is: light weight, has the advantages such as good fire prevention, without putrefaction.Existing manufacturing process first will mat formation into the plate natural air drying such as again after former to vermiculite power, string or wood-fibred mix and blend, formerly manually adds glue afterwards, spreads wooden skin and paste.Shortcoming is at the bottom of efficiency, the time is long, make local large, product density is poor, not firm, easily separated.Existing composite board product, as Chinese patent application 201110185171, wherein adopt the vermiculite power fire proofing material of single kind, intensity and the fire resistance of product are poor, and cannot directly glue note melamine decorative cover.
Summary of the invention:
For the defect that prior art exists, the object of this invention is to provide a kind of preparation method of bamboo fiber composite board, its composite plate adopts the one-time formed method of hot pressing to produce, production efficiency is high and end product quality stable, in addition because its composite plate adopts the one-time formed method of hot pressing to make so there will not be uneven absciss layer in finished product composite plate, also greatly can improve the appearance of composite plate by pasting melamine decorative cover simultaneously.
The present invention solves the technical scheme that its technical problem takes: a kind of preparation method of bamboo fiber composite board, key is that described bamboo fiber composite board comprises the following steps:
1) bamboo fibre and shell are pulverized separately respectively by grinding machine, be mixed to form mixture afterwards;
2) in above-mentioned mixture, bamboo fibre is 30% ~ 70% of mixture total weight amount, and the oven dry weight of oyster shell whiting is 25% ~ 65% of gross weight;
3) mixture that upper step obtains is carried out drying to moisture content 4 ~ 8%;
4) mixture is joined in sizing applicator stir, add macromolecule glue, waterproofing wood agent, obtain original slurry material, the weight of described macromolecule glue is 5 ~ 20% of above-mentioned pulverulent mixture gross weight, and the weight of waterproofing wood agent is 8 ~ 15% of above-mentioned pulverulent mixture gross weight;
5) tabular is pressed in advance after mating formation according to the model of sheet material;
6) composite plate of pre-compaction forming is hot pressed into plate under the Parameter Conditions of hot pressing time 300-400 second, temperature 180-200 degree Celsius, pressure >=9MPa/cm2.
Described composite plate adopts and method once compressing for the raw material of tabular is made.
Described macromolecule glue is Lauxite or white glue with vinyl.
Described composite plate thickness is 12mm.
Containing curing agent NH4CL, curing agent NH4CL in described macromolecule glue is 1% of macromolecule glue water quality.
The preparation method of bamboo fiber composite board of the present invention adopts bamboo fibre to mix with shell, improve the fire-retardant of sheet material and fire resistance, and adopt single interlayer original slurry material proportioning, integrated formed structure, have structural strength high, make simple, fire prevention, waterproof, Anti-moth-eating, density good, firm, can not absciss layer, flexibility function admirable, the advantage in melamine face can be pasted.
Accompanying drawing illustrates:
Fig. 1 is schematic flow sheet of the present invention.
Fig. 2 is the embodiment of the present invention one structural representation.
Fig. 3 is the embodiment of the present invention two structural representation.
