Abstract
The present invention relates to a kind of Large-specification recombination composite structural wood, and provide manufacture method, with recombinant material, adhesive, veneer and cardboard are raw material, use Lengthwise joint, MULTILAYER COMPOSITE, optimize the methods such as glue interface structure, manufacture Large-specification recombination composite structural wood, the present invention solves recombinant material secondary gluing process and causes cracking because gluing is bad, come unglued, bonding strength is low, the physical mechanics property loss of energy is big waits the technical bottleneck hindering recombinant material for Large-specification recombination composite structural wood, Large-specification recombination composite structural wood may be used for being manufactured into beam, post, furniture and floor.
Description
Technical field
The invention belongs to the wood-based plate in industry of artificial boards and manufacturing technology field thereof, be particularly suited for mechanics
Performance requirement is high, building and the Engineered Wood Products such as beam, post, furniture and floor that specification is big.
Background technology
Recombinant material is a kind of novel building and Engineered Wood Products, including Recombined bamboo and Scrimber, is by bamboo
Bundle and wood bundle are fabricated by through operations such as impregnation, dry, assembly and gluings.At present, recombinant material
Production technology is broadly divided into two big classes: a class is cold forming, heat curing process, is called for short cold-press process；
Two is to use for reference wood-based plate conventional thermocompression technique, the recombinant material heat pressing process of formation.Due to by cold press and
The restriction of the specification of hot press device, at present, the specification of recombinant material is the least, as colded pressing
The specification (length × width x thickness) that the recombinant material square stock that method produces is conventional is: 193cm × 10.5cm
× 15.0cm and 200cm × 14.5cm × 15.0cm；The recombinant material stock size that heat pressing process produces is (long
× width x thickness) be: 244cm × 122cm × (1.5-4) cm, maximum breadth also can only achieve 500cm
× 120cm × 5cm (Yu Wenji, China's Recombined bamboo industry development present situation and trend analysis, timber industry,
2012,26 (1): 11-14).Such specification is difficult to meet structural wood such as beam, post, big
Type furniture and the specification requirement on big specification floor.
At present, the structural wood of big specification is generally used Lengthwise joint by the material of small dimension, laterally spells width,
Glued joint with MULTILAYER COMPOSITE and form.Glued joint bad meeting and cause the decline of plate property, glued joint common defect
Type includes: degumming, crack, space, bondline thickness variation, solidification not exclusively lack with surface preparation
Falling into, wherein, it is main that defect is prepared on degumming, crack and surface.Affect adhesive bonding of composites strong
The principal element of degree has: the material category of connected piece, the ratio of rigidity of connected piece and thermal coefficient of expansion
Etc. the impact of factor, make by the rigidity approximately equal of bonded part, thermal expansion and suction the most as far as possible
Hygral expansion close (benefit little Su, composite handbook, Chemical Industry Press, 2009).
Chinese patent 201010243351.7,201020279829.7,201020279815.5 provide
A kind of employing undersized log manufactures undersized log recombination structure material and manufacture method thereof by finger or mitered,
Adopt the recombination structure material that undersized log can be processed into big specification in this way.But this technique is two
The glue-line glue performance formed during secondary gluing is unstable, has certain variability, some sheet material glue-lines
It is likely to occur cracking, the phenomenon such as come unglued；Other sheet materials are deposited, and are likely to occur bonding strength low, physics
The problems such as mechanical property loss is big.By analyzing, the main cause causing above-mentioned phenomenon and problem is office
Portion's gluing is bad.
According to previously research: form good splicing prerequisite and be adhesive molecule and gluedd joint material
(timber) can be fully contacted and effective wetting (Gu Jiyou, adhesive and coating, China Forest publication
Society, 1999).Recombinant material is a kind of porous natural material timber or bamboo wood (is colded pressing at bigger pressure
Method briquetting pressure about 60MPa, pressure sintering briquetting pressure 4～6MPa) effect compacted under, recombinant material
Density be generally higher than 1.0g/cm3, when environment temperature and humidity change, it may occur that easement, crosswise concaving,
Warpages etc. deform, and can produce the jumping phenomenon such as silk and cracking (Yu Wenji, China's Recombined bamboo industry time serious
Development status and trend is analyzed, timber industry, and 2012,26 (1): 11-14), even if in processing
Process uses sanding, it is also difficult to obtain smooth cemented surface；Secondly, in the manufacture process of recombinant material,
In order to make adhesive distribution more uniform, after generally using dipping method, bamboo bundle and wood bundle by impregnation,
One layer of adhesive has all been wrapped up on surface, after solidification, defines the glue-line of one layer of insoluble insoluble densification, table
Face wetability declines；Furthermore, recombinant material intensity is high, and hardness is big, it is difficult to compressed, but by tradition
Thinking affects, and when selecting bonded part, selects rigidity approximately equal, thermal expansion and moisture expantion phase as far as possible
Near material, does not generally take into account that the third material introduced in addition to adhesive, therefore, coarse table
Face, it is difficult to the splicing face compressed and bad wetability easily produces degumming in post forming process, splits
The recombinant material spot gluing of the adhesive defects, particularly high rigidity such as seam, space, bondline thickness variation is not
Good problem fails effectively to be solved all the time.
Summary of the invention
