Description
Technical field
Manufacture field the present invention relates to artificial board, and in particular to it is a kind of by sandwich layer of DDGS without aldehyde laminated particle-board and
Its preparation method.
Background technology
Traditional particieboard, through flaking, drying, is glued, mated formation, in advance using timber or wood machining residues as primary raw material
The processes such as pressure, hot pressing, cutting, cooling, sanding, saw side are made.2015, China's particieboard yield was 2030 ten thousand steres, mistake
10 years average annual growth rates are gone to reach 13.4%.Adhesive used in particieboard is mainly formaldehyde system thermosetting resin, and it is glued particieboard
The problem of there is Form aldehyde release.According to《Environmental protection integrates register (version in 2015)》, do not meet《Indoor decorating and refurnishing materials people
Form aldehyde release in plate and its product is made to limit the quantity》(GB18580-2001) in Form aldehyde release limitation E1 standards or《Environmental labelling product
Technical requirements-wood-based plate and its product》(HJ571-2010) the wood shavings panel products of standard will be listed in " excessive risk, high pollution production
Product ", production, circulation, outlet in terms of be restricted and prohibit the use of, therefore improve wood shavings panel products environmental protection grade be must
Right development trend.On the other hand, because the forest reserves of China are more poor, timber supply and demand contradiction is an outstanding problem,
Develop non-wood material and be significant to solving wood-based panel industry insufficient raw material.
DDGS is writing a Chinese character in simplified form for Distillers Dried Grains with Solubles (distiller's dried grain and its DDGS).
DDGS is the accessory substance after the cereal crops preparing ethanol by fermentation such as corn, sorghum, sweet potato, barley, contains crude protein, fat and fibre
Dimension, current DDGS is mainly for the production of vinasse albumen feed.Zhao Xiaobin (wood-based plate with vinasse based reinforcement material and with its prepare
Vinasse base is without aldehyde glue, Chinese invention patent, the A of application publication number CN 103725253) DDGS is applied to industry of artificial boards, system
Standby wood-based plate there is no DDGS to prepare the report of wood-based panel product as raw material with without aldehyde adhesive at present.
The content of the invention
To solve the above problems, the invention provides it is a kind of by sandwich layer of DDGS without aldehyde laminated particle-board and its preparation side
Method；Be it is a kind of by raw material of productional surplus thing, wooden-non-wooden material's laminated particle-board of formaldehydeless release and its preparation side
Method.
It is a kind of using DDGS as sandwich layer without aldehyde laminated particle-board, be to make to be dug by raw material of DDGS and wood particle
Card；The DDGS account for raw material weight than 20-40%, wood particle account for raw material weight than 60-80%；The DDGS and plane
Colored percentage by weight sum is 100%.Preparation method is as follows：First DDGS is pre-processed；By pretreated DDGS and wood shavings
The glue mixing in glue mixer with adhesive respectively；DDGS after glue mixing and wood shavings place Min layers are pretended as slab；Layering when mating formation by
Order according to wood shavings, DDGS, wood shavings is layered on the wood shavings weight phase on slab bottom, sandwich layer and top layer, wherein bottom and top layer successively
Together, slab is formed, steel slab surface sprays releasing agent or using the separation layer demoulding；It is prepared into according to existing heat pressing process and meets country
Standard GB4897-2015 and GB18580-2001 requirement without aldehyde laminated particle-board.
The DDGS is the residue after the cereal crops preparing ethanol by fermentation such as corn, sorghum, sweet potato or barley, including
One or more in dry full vinasse (DDGS), dry crude vinasse (DDG), distiller's dried grain DDGS (DDS), preprocessed conduct afterwards
Particieboard core layer raw material.
The pretreatment is that processing is stripped to DDGS using absolute ethyl alcohol, and concrete operations are as follows：Using soxhlet type
Device is stripped 1 hour, and absolute ethyl alcohol and DDGS mass ratioes are 5:1；Nature is stood after extracting terminates, after DDGS is filtered to do
It is dry, selected through 60-80 mesh sieves, remove wherein meticulous dust；Remaining ethanol is recyclable after extracting；DDGS after extracting
Wherein most albumen, fat constituent are eliminated, fiber percentage composition is improved, egg when efficiently solving high temperature hot pressing in DDGS
The problem of white Partial digestion.
The wood shavings are the wooden surface layer wood shavings or other biomass wood shavings materials of particieboard production；Wood shavings length 0.1-
1mm, width 0.2-0.4mm, thickness 0.2-0.4mm, moisture content is 8-12%.
The adhesive is poly- methyl diphenylene diisocyanate, and adhesive addition is wood shavings oven dry weight ratio in wood shavings
4-6%；In DDGS adhesive addition be DDGS oven dry weights than 3-5%.
The hot pressing process is 170-190 DEG C of hot pressing temperature, hot pressing time 35-50s/mm, hot pressing pressure 3-5Mpa.
Beneficial effects of the present invention：
The present invention is using the residue DDGS of ethanol production as particieboard core material, the alternative 20-40% after extracting
Wood shavings, expand the source of Wood-based Panel Production raw material, have simplified raw material preparation process, have reduced production cost.Due to DDGS
Geomery is small compared with wood shavings variability, and slabbing, the more conventional particieboard of laminated particle-board core structure prepared evenly,
Densification, internal bond strength can improve 20%-30%, and the characteristics of particieboard top layer still has wooden boards can be carried out after sanding
Secondary operation (veneer etc.).Sheet material preparation process uses isocyanates for adhesive, the formaldehydeless release of product.Particieboard items thing
Reason performance indications reach the requirement of national particieboard standard and with a little fragrance, the need for disclosure satisfy that industrialized production.
