Description
Technical field
The present invention relates to a kind of artificial boards and preparation method thereof, and in particular to a kind of Chinese Kenaf Core Buffer green ecological plank and
Preparation method.
Background technology
Artificial board is using timber as primary raw material, but the consumption of a large amount of timber and current protection forest, maintenance ecology are flat
The environmental protection concept of weighing apparatus contradicts.Currently, the protection due to various countries to environment and the forest reserves, gradually limitation processes people using timber
Plate is made, but demand of the society to wood-based plate is continuing to increase.Attention is gradually transferred to crop residue stalk by people
Come up, such as corn, straw, soybean, cotton stalk is used to produce artificial board as raw material.But all because raw material should not be received on a large scale
Purchase leads to not industrialized production.
Simultaneously as the adhesive containing formaldehyde has been used when producing wood-based plate, so wood-based plate was actually using
Meeting slow release goes out formaldehyde in journey, causes room air pollution, and then damage to health.The World Health Organization has incited somebody to action
Formaldehyde is classified as potential danger carcinogenic substance and important environmental contaminants.GB 18580—2001《Indoor decorating and refurnishing materials wood-based plate
And its Form aldehyde release limitation of product kind》The Form aldehyde release limit index of defined various types of wood-based plate is as shown in table 1, and
The regulation of industrially developed country's similar product lies substantially in same level.Therefore the environmentally friendly people of formaldehydeless release is produced
Make the common recognition that plank has become people.
Burst size of methanal test method and Limited Doses in 1 wood-based plate of table and its product
When due to manufacture artificial board of straw, isocyanates resin added is smaller, and the surface of stalk unit is very big how
It realizes efficient uniform sizing, is a significant technology issues.
Invention content
The object of the present invention is to provide a kind of Chinese Kenaf Core Buffer green ecological plank and preparation method thereof, sides provided by the invention
Method is a kind of sufficient raw material, board quality and high intensity, fire-retardant, antibacterial, not release formaldehyde, product qualified rate height, production efficiency
High, on-deformable method has the functionality such as fire-retardant, antibacterial, formaldehydeless while being not added with other auxiliary agents, is multi-functional green
Color composite board.
The preparation method of Chinese Kenaf Core Buffer green ecological plank provided by the present invention, includes the following steps：
(1) Chinese Kenaf Core Buffer is crushed, solid material is then made；
The solid material is in rod-shaped, blocky or granular；
(2) it is 2%~18% to dry the solid material to quality moisture content；
(3) solid material after step (2) is dry is glued；
The resin added of the sizing is the 1%~15% of the butt quality of the solid material；
(4) mated formation the solid material after step (3) sizing to obtain plank；
(5) plank is subjected to hot pressing to get to the Chinese Kenaf Core Buffer ecological sheet material.
In above-mentioned preparation method, in step (1), the Chinese Kenaf Core Buffer powder is broken into the block that grain size is 10mm~200mm
Shape.
In above-mentioned preparation method, in step (2), it is 10% that the solid material, which is dried to quality moisture content,；
The temperature of the drying can be 105 DEG C~125 DEG C；
The drying steps carry out in rotor-type drier or channel-type drying machine.
The mode of the sizing can be to impregnate, brush or spray；
High atomisation spraying colloid system is such as used, glue is atomized using centrifugal atomizer and realizes sprinkling.
In above-mentioned preparation method, in step (3), the adhesive used that is glued can be isocyanate adhesive, water
At least one of property polyurethane adhesive, fluorine class adhesive, aqueous macromolecule-isocyanate adhesive, protein adhesive and gelatine.
In above-mentioned preparation method, in step (4), it is described mat formation mat formation by the way of four precompressed using three, i.e., first
Road spreading machine spreads precompressed after one layer of raw material, and second spreading machine repaves precompressed after one layer of raw material, and third road spreading machine repaves one layer
Raw material then precompressed, finally enters whole precompressed, 4-8 times in production board of slab thickness after precompressed control.
It is used in conjunction with using classification spreading machine or mechanical spreading machine or classification spreading machine and mechanical spreading machine.
In above-mentioned preparation method, in step (5), the pressure of the hot pressing can be 3Mpa~8Mpa, the hot pressing when
Between can be 0.4min~1.2min/mm, the temperature of the hot pressing can be 170 DEG C~200 DEG C.
Further include that the plank is subjected to cooling, cutting edge and sanding step in above-mentioned preparation method, after step (5)
Suddenly.
Chinese Kenaf Core Buffer green ecological plank provided by the invention remains antibacterial, mould proof, absorption, micropore of Chinese hemp stalk etc.
Biological nature, adhesive therein by and boony fibre, lignin, sugar in hydroxyl and waste of flax in combination water, trip
Firm chemical reaction has occurred from water, therefore not only density is low for made plank, and be also a kind of strength is high, waterproof is good,
Formaldehydeless, flame-proof antibiotic environment-friendly and green composite board, while manufacture craft is simple, efficient, high yield rate.
