Abstract
The invention discloses a kind of brush wood is mixed by a certain percentage with bamboo cane or wood chip after compacting Scrimber blank, it is to utilize bamboo cane or wood chip even thickness, the preferable advantage of linearity, when bamboo cane or wood chip mix compacting with brush wood, good cushioning effect can be played, alleviate the defect of branch recombinant material Density inhomogeneity.The main raw material(s) that the present invention uses is all low-grade corner or discarded material, carries out twice laid, energy-conserving and environment-protective.Scrimber (bamboo) blank performance that the brush wood that preparation method of the present invention obtains mixes with bamboo timber is excellent, and every prevailing quality performance indications such as MOR, internal bond strength, thickness swelling rate are all superior to not improve the pure branch integrated timber of making.The brush wood blank sheet material being mixed with bamboo wood sheet maintains the highest intensity, has the texture attractive in appearance of pith cutting plane, and match in excellence or beauty the Nature timber, ratio general natural tree more hard durable, it is anticipated that it has wide market prospect.
Description
Technical field
The present invention relates to Scrimber blank and preparation method that a kind of brush wood mixes with bamboo timber, belong to the processing of bamboo wood
Field.
Background technology
Bamboo-wood composite material refer to bamboo wood and timber be combined with identical or different construction unit form and glued joint and
The composite board become or square bar, it has various ways, such as bamboo wood composite veneer, laminated bamboo-wood composite lumber, the compound plane of bamboo wood
Card and medium density fibre board (MDF), bamboo batten aligned lumber etc..Dividing from the angle of materials classification, it is broadly divided into structure and uses
Bamboo-wood composite material and the big class of Functiaonl bamboo wood composite material two.Wherein, structure bamboo-wood composite material mainly makees engineering structure
Part uses；And Functiaonl bamboo wood composite material is mainly used in decoration and furniture makes.Brush wood Scrimber, is that timber is artificial in recent years
Novel product in board industry, major advantage is discarded brush wood, or low-density fast growing wood is pressed into square stock, makees
For floor or Furniture panel etc., panel density is high, beautiful texture.But this brush wood Scrimber is due to its raw-material office
Sex-limited, such as brush wood thickness is uneven, and bending is serious, and Scrimber blank brush wood hybrid stack-ups together suppressed is past
Uneven toward panel density can be formed, hole the most glued more bad defect.It is desirable to provide one is by brush wood
After mixing by a certain percentage with bamboo cane or wood chip, the blank of compacting, is to utilize bamboo cane or wood chip even thickness, and linearity is preferable
When advantage, bamboo cane or wood chip and brush wood mix compacting, good cushioning effect can be played, alleviate branch recombinant material close
Spending uneven defect, can add the Radix Cinnamomi porrecti timber possessing function for expelling pests simultaneously, the Scrimber blank being novel has anthelmintic
Function.The novel recombinant wood floor blank suppressed, even density, hole is less, and glued good, stability is high.
Summary of the invention
The present invention is directed to the problem that background technology exists, it is provided that a kind of brush wood Scrimber blank possessing function for expelling pests,
On the basis of making full use of corner or remaining timber, add bamboo wood or wood chip, make product density uniform, glued good,
Stability is higher.
The inventors discovered that, in brush wood, mixing has the lignum cinnamomi camphorae wood chip of function for expelling pests, the Scrimber base after compacting
Material, for the interior decoration such as ground pavement, furniture field, not only improves the attractive in appearance of domestic environment, disinfests simultaneously, improve ring
Border health.
The inventors discovered that, by brush wood and bamboo wood high-temperature heat treatment, bamboo timber can be modified, obtain after making compacting
To Scrimber blank because using humid environment and the change being dried and the phenomenon that deforms will not be it is obvious that also make in timber
Starch and sugar etc. in the material that moth relies on decompose because of high temperature, so that moth cannot survive.
The purpose of the present invention is achieved through the following technical solutions:
The production method of the recombinant wood floor that a kind of brush wood mixes with bamboo timber, its step is as follows: 1, prepare raw material: will
Brush wood is cut into fixing length, such as 1.95m, puts into chaser (chaser is specially a kind of brush wood and rolls breaker)
Carrying out broken rolling, brush wood is flattened pressure break, it is 0.3mm～3.0mm that bamboo wood or timber cut into thickness, width 5mm
～150mm, length is also strip or the lamellar shape unit of 1.95m, and bamboo wood unit therein needs to roll sliver；
2, drying: brush wood and bamboo chip, wood chip after rolling are dried, drying temperature is 40～60 DEG C, after drying
Moisture content 10～16%；
3, superhigh temperature heat modification: the bamboo chip after prebake and the brush wood wood chip after rolling process are inserted carbonization and processes and set
Standby, be warming up to 80 DEG C with the speed of 8 DEG C/min and be incubated 2-3 hour, then with the speed of 10 DEG C/min timber is warming up to 160～
200 DEG C keep 90-180min, then stop heating cooling spraying steam damping moisture regain, moisture content 6～12% after moisture regain, cooling
Kiln discharge；
4, impregnation is dried: the brush wood after high temperature modified and bamboo chip wood chip is inserted pressurized tank and carries out impregnation, and glue is leaching
Stain phenol glue, equipment is pressurized tank, and pressure 0.2～0.5MPa, is dried after impregnation at time 10～40 minutes, dries temperature
Degree is 40～60 DEG C, moisture content 6～15% after drying；
5, making sheet: weigh the brush wood after 25kg impregnation is dried, after weighing the wood chip after 15kg impregnation is dried, arbitrarily mixing
Put into precompressed charger, enter back into the compacting of Recombined bamboo press, after the solidification demoulding, i.e. obtain brush wood floor blank.
As preferably, containing Radix Cinnamomi porrecti wood chip in added wood chip.
The inventors discovered that, when using the Radix Cinnamomi porrecti wood chip containing 20-50% in wood chip, not only there is vermins-proof effect, also may be used
So that blank density is evenly, reduce floor blank hole and glued risk.
The invention have benefit that:
1. what the present invention used is all leftover bits and pieces, carries out twice laid, energy-conserving and environment-protective.
2. the present invention is to utilize bamboo cane or wood chip even thickness, the preferable advantage of linearity, bamboo cane or wood chip and brush wood
When mixing compacting, good cushioning effect can be played, alleviate the defect of branch recombinant material Density inhomogeneity.Suppress
Novel recombinant wood floor blank, even density, hole is less, and glued good, stability is high.
3. the inventors discovered that, when using the Radix Cinnamomi porrecti wood chip containing 20-5% in wood chip, not only there is vermins-proof effect, also may be used
So that blank density is evenly, reduce floor blank hole and glued risk.
Detailed description of the invention
The brush wood of the present invention is to manufacture the remaining leftover bits and pieces wingceltis tree brush wood of rice paper.
