Description
Technical field
The present invention relates to a kind of composite plate and its processing technology field, more particularly to a kind of bamboo and wood recombinant material of utilization waste material Composite plate and its processing technology.
Background technology
Bamboo curtain splint be will after bamboo fragmentation formed 1-2.5mm thin bamboo strip, then with rope by bamboo chip braiding form.Due to timber It is complementary with culm property, using bamboo curtain splint and Wooden veneer, bamboo matter veneer as primary raw material group embryo, through first drying, apply adhesive, Secondary drying (drying glue), the bamboo-wood plyboard that assembly is made after hot pressing again has preferable mechanical property, container bottom board, Tool has been widely used in building template, furniture-plates.
However, after this bamboo-wood plyboard hot pressing four sides will trimming, produce trimming material, it is not up to standard in production process yet Produce the normal plywood after useless plate and use.The routine of the waste materials such as the normal plywood after trimming material, useless plate and use Processing method is as fuel or transforms the sheet material of other low values into, and its value is very low, and is had necessarily using scope Limitation, so as to cause raw material resources extreme waste.It is more next into various sheet materials that compacting is processed using timber and mao bamboon More, it processes remaining trimming material can increasing, and it is also many that useless plate low value changes that sanction uses, due to be fabricated to trimming material, Contain adhesive in common plate after useless plate and use, discarding is polluted to environment, also results in resource serious waste, is burnt Produced gas can pollute air.Therefore, how the common plate after trimming material, useless plate and use is efficiently utilized, carried Its high use value is a urgent Task.
The content of the invention
In order to overcome the shortcomings of existing research, patent of the present invention provides the bamboo and wood recombinant material composite plate using trimming material And its manufacturing process, the common plate after rim charge, useless plate and use is efficiently utilized, bamboo and wood recombinant material composite plate is manufactured, Making sheet cost is saved, it is to avoid the pollution that the common plate after trimming material, useless plate and use is abandoned or burnt to environment, simultaneously Composite plate mechanics performance is improved, the bamboo and wood is recombinated composite plate both has the excellent of bamboo high resiliency, high tenacity and the high ratio of strength to weight Point, and overcome the shortcoming that bamboo rigidity is low, mechanical property is discrete using veneer and core plate characteristic.To realize above-mentioned functions, The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
The invention discloses a kind of bamboo and wood recombinant material composite plate of utilization waste material, facing paper, veneer, bamboo curtain splint and core plate, most Upper first layer is facing paper, and the second layer is bamboo curtain splint or veneer, and third layer is veneer, if centre is dried layer veneer and no more than two The core plate of layer, bottom third layer is that veneer, the second layer are bamboo curtain splint or veneer, and first layer is facing paper or without each interlayer warp After impregnation, drying, group embryo, cold prepressing process, it is integrated using hot press hot pressing connects.Facing paper is in bamboo and wood recombinant material composite plate Upper and lower surface, more beautiful outward appearance is provided for bamboo and wood recombinant material composite plate；And consider the surface of core plate not as good as veneer and bamboo curtain splint It is smooth, and bamboo and wood recombinant material composite plate mechanical property, therefore, the second layer, third layer do not place core plate, core plate number up and down Amount is no more than two layers.
Further, the veneer is Bamboo veneer or veneer.
Further, the core plate levels are Bamboo veneer.Since it is considered that above and below the physical characteristic of Bamboo veneer, core plate Layer, which places Bamboo veneer, can strengthen the bearing capacity of whole bamboo and wood recombinant material composite plate.
Further, the core plate using trimming material, scrap plate, common plate as raw material, be sawed into uniform thickness by multiple blade saw It is molded after bar plate, gluing using side compression machine side pressure.
Further, the side compression machine hot compression parameterses are set to side pressure pressure 0.2Mpa-0.4Mpa, 125 DEG C -130 of temperature DEG C, the side pressure time, according to core thickness, calculated according to 0.9 minute/mm-1.2 minutes/mm.
Further, the side pressure mode of the side pressure turn 90 degrees side pressure mode to turn over.
A kind of bamboo and wood recombinant material of utilization waste material is combined board machining process, and its step is：
A, select species it is consistent, without worm channel, dog holes, sticking patch, loose joint bamboo, by bamboo fragmentation into 1mm0- after cleaning Thin bamboo strip wide 2.5mm, is then woven into bamboo curtain splint with rope by bamboo chip；
B, by trimming material, scrap plate, common sheet material and be put on equidistant multiple blade saw, be sawed into the bar plate of uniform thickness；
C, sawed bar plate is arranged side by side neatly, afterwards turns over side pressure in 90 degree, feeding side compression machine, make its whole Change, form core plate, side compression machine hot compression parameterses are set to side pressure pressure 0.2Mpa-0.4Mpa, 125 DEG C -130 DEG C of temperature, during side pressure Between according to core thickness, calculated according to 0.9 minute/mm-1.2 minutes/mm；
D, by facing paper, veneer, bamboo curtain splint, core plate distinguish impregnation, impregnation resin content be not less than after 350g/ ㎡, impregnation send into drying Machine is dried, in case group embryo, dryer temperature is 150 DEG C -160 DEG C；
E, the facing paper by after drying, veneer, bamboo curtain splint, core plate group embryo, organizing embryo mode is：The top first layer is decoration Paper, the second layer is bamboo curtain splint or veneer, and third layer is veneer, if in the middle of being then dried layer veneer and the core plate no more than two layers, most Third layer is that veneer, the second layer are bamboo curtain splint or veneer below, first layer be facing paper or without；
Placed 25-35 minutes after F, group embryo, cold prepressing was then completed in 2 hours, cold prepressing gauge pressure is 16MPa- Hot press is sent into after 20MPA, cold prepressing, and it is hot-forming in 8 hours, it is manufactured into bamboo and wood recombinant material composite plate；
G, by the bamboo and wood recombinant material composite plate of manufacture be put into it is shady and cool dry place, natural cooling is carried out after placing 24 hours Side is sawed, examines, grade.
Further, the impregnation in the step D is in immersion phenolic impregnated resin glue.
Further, the drying in the step D is less than 12% state for drying to moisture content.
Further, the parameter of hot press hot pressing is set to hot pressing unit pressure 2Mpa-2.4Mpa in the step F, heat Press temperature：125 DEG C -135 DEG C, hot pressing time was combined plate thickness according to bamboo and wood recombinant material, according to 0.7 minute/mm-1 minutes/mm Plate thickness is calculated.
Beneficial effects of the present invention：
1. the common plate after pair rim charge, useless plate and use repeat efficiently utilizing, it is to avoid trimming material, useless plate and The pollution that common plate after use is abandoned or burnt to environment.
2. having saved the manufacturing cost of bamboo-wood plyboard, while improving the mechanical property of bamboo-wood plyboard, make the bamboo and wood Restructuring composite plate had both had the advantages that bamboo high resiliency, high tenacity and the high ratio of strength to weight, and was overcome using veneer and core plate characteristic Bamboo rigidity is low, mechanical property is discrete shortcoming.
