Abstract
The invention relates to a production method of a poplar laminated veneer lumber composite decorative plate, which is characterized by comprising the following steps: carrying out edge sawing and edge grinding treatment on poplar veneers, and further drying till the water content is lower than 7%; obtaining the dried veneers; carrying out repair and arrangement on holes on the dried veneers, then butting the veneers, and carrying out heating treatment on the butt joints to obtain the lengthened veneer; carrying out glue application and composition on the butted veneer, and forming the laminated veneer lumber; and carrying out cold pressing, heat pressing and polishing treatment and finally obtaining a finished product. The processing technology is reasonable, and the prepared composite plate has low warp degree, high density and excellent mechanical properties and can be used for various decorative plates, thereby promoting the processing and the utilization of poplar.
Description
Technical field
The present invention relates to a kind of production method of composite decorating board, particularly a kind of production method of poplar laminated veneer lumber composite decorating board.
Background technology
Poplar is a kind of fast-growing tree species, and it has characteristics such as wide adaptability, year growth period is long, speed of production is fast, and all there is plantation widely in China south and the north, and the poplar resource is than horn of plenty.Because aspen fibers by using silicon short texture, material are relatively poor relatively, its range of application is subjected to bigger restriction, and is main at present as solid wooden compound floor central layer or base plate, short-cycle industrial material material or road, river course green tree species.
Poplar laminated veneer lumber composite decorating board of the prior art only is each veneer to be carried out the compound hot pressing of lamination make when producing.Its processing technology is coarse, prepared composite plate angularity height, and density is poor, and mechanical property is relatively poor, has therefore limited the scope of application of poplar laminated veneer lumber.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, and the production method of the poplar laminated veneer lumber composite decorating board that more reasonable, the prepared composite plate angularity of a kind of technology is low, density is good is provided.
Technical problem to be solved by this invention is to realize by following technical scheme.The present invention is a kind of production method of poplar laminated veneer lumber composite decorating board, is characterized in, its step is as follows:

(2) after the hole that oven dry is existed on the veneer was repaired arrangement, length requirement on demand had been by carrying out the veneer butt joint to the edge fit gluing, and joint is carried out heat treated, and treatment temperature is 280-300 ℃, and be 12-14 second heat time heating time, the spreading veneer;
(3) it is compound on demand several interconnected boards to be carried out gluing, forms laminated timber; With the forming machine of colding pressing laminated timber is carried out the normal temperature typing then, typing pressure is 7 * 10
5-9 * 10
5Kgf/cm
2, the time is 40-60 minute, the laminated timber of must finalizing the design;
(4) the typing laminated timber is carried out hot-pressing processing, processing pressure is 9-10kgf/cm
2, temperature is 110-120 ℃, the processing time=in the typing laminated timber thickness of millimeter * (1-2) minute, composite plate, at last composite plate is carried out polishing, get product.
The production method technical scheme of above-described poplar laminated veneer lumber composite decorating board of the present invention, its optimal technical scheme is as follows:
1, in step (1), oven dry is preferably carried out under 120 ℃.
2, in step (2), treatment temperature is preferably 300 ℃, is preferably 13 seconds heat time heating time.
3, in step (3), typing pressure is preferably 8 * 10
5Kgf/cm
2, the time is preferably 50 minutes.
4, in step (4), the pressure that the typing laminated timber is carried out hot-pressing processing is preferably 9.5kgf/cm
2, temperature is preferably 115 ℃, preferred process time=and in the typing laminated timber thickness of millimeter * 1.5 minutes.
5, in step (2), (3), employed glue is preferably phenol glue during the gluing operation, and coating weight is preferably 360-400g/m
2Phenol glue of the present invention can be the phenol glue that is applicable to timber processing of disclosed any production method preparation in the prior art, also can be the commercially available phenol glue that is applicable to timber processing.Certainly, employed glue also can be any glue that is applicable to timber processing in the prior art when gluing of the present invention was operated, but best environmental protection glue.
Compared with prior art, process using edging of the present invention, oven dry, repair, cold pressing and processing step such as hot pressing, and the preferred technological parameter of each step, its processing technology is reasonable, prepared composite plate angularity is low, and the density height has preferable mechanical property, can be used as various decorative plates, promote the processing and utilization of poplar.
