Description

A kind of preparation method of the not mould non-ignitable bamboo fiberboard of no aldehyde
Technical field
The invention belongs to artificial bamboo board fields, and in particular to a kind of preparation method of the not mould non-ignitable bamboo fiberboard of no aldehyde.
Background technology
The bamboo processing technology and level of China occupy rank first, and artificial bamboo board is the major product of bamboo processing And core.Wherein bamboo fibreboard is excellent because having the characteristics that even structure, processing performance, in the industries such as building, furniture once Through obtaining more application.But bamboo fiberboard manufacture is substantially all using formaldehydes adhesive, production, use in bamboo fiberboard Harmful substance formaldehyde can be discharged in the process, larger harm is caused to the health of practitioner and consumer, it would be highly desirable to research and develop Without aldehyde type bamboo fiberboard.In addition, nutriment necessary to the moulds such as contained carbohydrate, starch, protein is long-range in itself for bamboo wood In timber, bamboo fiberboard is caused to be easier to go mouldy more than wood fiberboard in the larger area of humidity and moist place, not only The performance of product is reduced, and pollution is caused to application environment, it would be highly desirable to research and develop mould-proof-type bamboo fiberboard.In addition, bamboo fibre Plate is mainly used for the fields such as furniture, construction and decoration, however bamboo fiberboard belongs to combustible material, easily burns, once it builds Fire, it is most likely that cause casualties and property loss, it would be highly desirable to research and develop flame retardant type bamboo fiberboard.
CN107032740A discloses a kind of bamboo fibre magnesium oxysulfide plate and preparation method thereof, which includes Following materials in percentage by mass:Distiller liquor 20~30%, cement 20~35%, bamboo fibre 20~35%, flyash 20~35%, Curing agent 2~3% and strength assistant agent 0.5~2%, the bamboo fibre magnesium oxysulfide plate which is provided have A grades of fire-retardant fireproofs, prevent Damp, anticorrosive, insect prevention, a variety of advantages such as durable, zero formaldehyde is environmentally protective, preparation method is simple, environmental protection, pollution-free.
But the bamboo fiberboard prepared in the prior art is mostly to have the function of in a certain respect, such as mould proof or without aldehyde, work( It can be single.Therefore, current develop has without formaldehyde, is not easy to go mouldy and not only compel very much with the needs of nonflammable bamboo fiberboard It cuts, and for widening the application range of Recombined bamboo and realizing more extensive use etc. of Recombined bamboo all with extremely important Realistic meaning.
Invention content
For solve in the prior art bamboo fiberboard contain formaldehyde, easily go mouldy, easily burn the problems such as, the present invention offer one Preparation method of the kind without the not mould non-ignitable bamboo fiberboard of aldehyde, bamboo fiberboard produced by the present invention are excellent with no aldehyde, mould proof, fire-retardant etc. Point.
In order to solve the above technical problems, present invention offer technical solution is as follows:
On the one hand, the present invention provides a kind of preparation method of the not mould non-ignitable bamboo fiberboard of no aldehyde, includes the following steps:
(1) bamboo section is produced
Using the bamboo wood of the small diameter grades such as Cluster Bamboo, miscellaneous bamboo as raw material, after at its sawed-off bamboo section for certain length, it is placed in small Rotary-cut is carried out on type rotary trunk-layer stripping machine without clamper, revolves after removing and stops substantially in the bamboo blueness of bamboo section outer surface and bamboo acromere;
(2) bamboo section vertical profile and bamboo block remove tabasheer and internal segment
It will revolve to cut open except the bamboo section longitudinal direction of bamboo blueness and acromere and cut as 2-3 block bamboo blocks, and reject tabasheer and internal segment on bamboo block later;
(3) bamboo block is chipped
By the bamboo block without bamboo blueness, tabasheer and ring, it is sent into the drum chipper of positive feed and chips, bamboo block is cut into The bamboo chip that length is 15-25mm, width 15-20mm, thickness are 2-3mm, bamboo chip moisture content are maintained between 30-50%;
(4) bamboo chip prepares bamboo fibre
Bamboo chip is separated by bamboo fibre using thermomechanical method, the temperature of wherein steam heating boiling is 160-180 DEG C, is steamed Boil time 4-8min;
(5) the mould proof processing of bamboo fibre
It, later will by metering pump or flow valve by bamboo fibre with being sent into round roller of the inside with blender Mould inhibitor is applied to by the top of roller on bamboo fibre, and applying mould inhibitor, blender persistently stirs simultaneously, makes mould inhibitor and bamboo Fiber uniformly mixes, and the applied amount of mould inhibitor is the 2-6% of over dry bamboo fibre quality;
(6) mould proof bamboo fibre drying
It is dried aqueous to the bamboo fibre Jing Guo mould proof processing using the vertical Air Dried System drying of duct type two level Rate is controlled in the range of 5-10%;
(7) mould proof bamboo fibre applies without the non-ignitable cementing material of aldehyde
Bamboo fibre is applied without the non-ignitable cementing material of aldehyde, the applied amount of no non-ignitable cementing material of aldehyde using pipeline resin application methods Solid weight for glue accounts for the 30-45% of over dry bamboo fibre quality;
(8) sizing bamboo fibre is mated formation
The bamboo fibre of cementing material will be applied, and be paved on belt with mechanical forming machine and obtain slab;
(9) slab precompressed
Continuous precompressed is carried out to the slab after mating formation using Continuous Roller press, makes slab just one-step forming;
(10) slab hot pressing
Carry out hot pressing to shaping slab using the double steel band hot presses of continous way, heat pressing process in existing continous way timber The technological parameter of density fiber board production is identical, and the flash plate without the not mould non-ignitable bamboo fiberboard of aldehyde can be obtained after hot pressing;
(11) post-processing
By the flash plate of the not mould non-ignitable bamboo fiberboard of no aldehyde, it is placed in and combines in length and breadth on edge cutting machine to the length of fiberboard flash plate Degree and width are processed to get the sketch-plate of the not mould non-ignitable bamboo fiberboard of no aldehyde;Sketch-plate is placed in temperature as 30-40 again DEG C, carry out in the balance room that humidity is 50-70% after modifier treatment 36-96h to get the not mould non-ignitable bamboo fiberboard finished product of no aldehyde.
On the other hand, the present invention also provides a kind of mould inhibitors, can be applied to the preparation method process of above-mentioned bamboo fiberboard In, the mould inhibitor is Chinese herbal medicine mould inhibitor, nanometer silver-colored zinc composite mildew inhibitor or Chinese herbal medicine/nanometer silver-colored zinc composite mildew inhibitor.
Further, the preparation method of the Chinese herbal medicine mould inhibitor is:
By medicinal herb soak in 40-70% ethanol solutions, the mass ratio of the Chinese herbal medicine and ethyl alcohol is 1:5-20, heating To 50-80 DEG C, filter residue is filtered to remove after heating 30-120min, the Chinese herbal medicine for obtaining a concentration of 50-100mg/ml of Chinese herbal medicine is mould proof Agent;
