Description
Technical field
The present invention relates to a kind of plywood preparation method, specifically, it is related to a kind of high intensity prosthetic Form aldehyde release glue
Plywood preparation method.
Background technology
Artificial forest, is using artificial seeding, plants or the forest cultivated is built in the methods and techniques measure such as cuttage, be
The main raw material(s) woods of world's forest chemical, particularly China, Brazil, South Africa, India etc. are a large amount of to plant artificial forest, wherein China
Artificial forest has reached 53,250,000 hectares, ranks first in the world, and only eucalyptus plantation area reaches 17,000,000,000 square metres, Poplar Plantation
Area reaches more than 700 hundred million square metres, has formed southern " eucalyptus globuluss " north " poplar " Plantation Community.Artificial forest trunk leads to straight, beautiful texture, raw
Thing amount is high, can be widely applied to the fields such as composite wooden material, pulping and paper-making.Wherein prosthetic Form aldehyde release fiber composite is advanced
Material, green technology for making paper are the Disciplinary Frontiers of artificial forest wood intensive processing research, need wood cell wall in conjunction with its crucial work
Skill is efficiently to combine between wood cell wall, forms enough bond strengths.However, prior art mainly adopts ureaformaldehyde, phenolic aldehyde
Deng resin realize wood cell bonding, the harmful substance such as the easy release formaldehyde of product, free phenol and cause indoor environment severe contamination,
Cause the major diseases such as leukemia.
Wherein realize between wood cell wall efficiently in conjunction with, always Wood Science man research focus, wherein big chi
Degree timber combines and interference fit stress frequently with tenon, realizes the firm mechanical bond of timber.But between little yardstick wood particulate efficiently
In conjunction with the key being wood composite processing.Early in 105 years Christian eras, Cai Lun invented papermaking technology, had started between fibrocyte again
Combination technology is applied.After phenolic resin and Lauxite are invented, wet laid fiber bonding technique once occupied the principal status of public economy, but deposited
In a large amount of waste water and residue pollution；By technology upgrading improvement, dry method woody debris bonding technique is with environmental protection, efficiently etc. excellent
Gesture, it is glued to instead of rapidly wet laid fiber, and to the end of the year 2011, global dry-process fiberboard yield reaches about 100,000,000 m3.However, adopting
During resin-bonding carries out dry-process fiberboard and particieboard production and products thereof use, create a large amount of formaldehyde, free phenol etc.
Pollutant, the ring that seriously threaten people occupies safety and life and health.In order to eliminate the negative effect of the resinoid bonds such as ureaformaldehyde, state
Some scholar's priorities inside and outside make use of the way that multiple means discussion such as physics, chemistry, biology realizes wood cell wall Binderless binding
Footpath.However, current wood cell wall Binderless binding there are still the defects such as bond strength deficiency, tedious process, inefficiency, lead
Fibre board, particieboard no hydroformylation is caused not to be applied by technical scale in conjunction with process technology.We recent studies have shown that, only according to
Bonding capacity by half fiber or lignin is difficult to wood cell wall high intensity Binderless binding, and in conjunction with timber can be promoted
Form the binder courses of high intensity, however, to wooden efficient bonding behavior feature and combining essential unclear, system between cell wall
The commercial application of about wooden advanced biology composite wood manufacturing technology.
In order to overcome this phenomenon, inventor lasts more than 20 year, costly, analyzes comprehensively《Composite fiber plate》(application
Number：02111211.8)、《Compacting and pressing and hardening cushions during the composite wood boards such as continuous production particieboard, fibre board
Method》(application number：03104109.4)、《Reduce the content of formaldehyde of particieboard and the method for burst size of methanal》(application number：
01811365.6) etc. on the basis of nearly 400 patents of invention, present invention applicant's original innovation fibre board, the fiber of particieboard
Particle is dried, prepared by adhesive, three operations of applying glue, prepares wooden advanced biology composite wood, attached for improving artificial forest wood
Value added with increase farmers' income offer technical support.
Content of the invention
