Description
Technical field
The present invention relates to decorative materials technology, relate in particular a kind of manufacture method of the finger-jointed plate with the concave-convex surface stereo relief effect.
Background technology
Existing finger-jointed plate mostly is planar products, and decorative effect is single, and the product with concave-convex surface stereo relief effect of minority also is to do the wire drawing processing after making platelet by artificial electric planer or saw, and production efficiency is low, effect of decorative patterns inconvenience control.
Regulation according to GB/T21140-2007, finger joint lumber refers to take sawn timber as raw material through referring to tenon processing, the plate square bar that glues together spreading and make, again with the plate square bar made on the width by the glue bonding after, finger-jointed plate is made in hot pressing, the raw material that uses is generally take fast growing wood as main, wherein use at most with poplar, the side of plate square bar width is the plane, difficulty of processing is large, structural strength is low after the bonding, so someone improves, application publication number CN 102192395 A for example, disclosure of the invention shown in the Shen Qing Publication day 2011.09.21 a kind of finger-jointed plate, this finger-jointed plate comprises the finger bar that is spliced by multistage sawtooth short slab, and the bonding plane between its finger bar is the inclined-plane.The finger-jointed plate of this invention by the bonding plane between the finger bar is designed to the inclined-plane, has increased the bonding and lifting surface area between the finger bar, so that finger-jointed plate is bonding more firm and in use more not easy to crack.But, even change the adhesive surface between the finger bar into inclined-plane, after making finger-jointed plate, the whole stability of plates of finger-jointed plate should be not, seam crossing is not tight, easily occurs depression after glue shrinks, the restriction that these problems are serious the application of finger-jointed plate in end product.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art part, a kind of manufacture method of the finger-jointed plate with the concave-convex surface stereo relief effect is provided, its finger-jointed plate structural strength of making is high, and stability is good, the quality problems of step and rat can not occur at seam crossing.
In order to solve the problems of the technologies described above, technical scheme of the present invention is as follows: the manufacture method with the finger-jointed plate of concave-convex surface stereo relief effect may further comprise the steps:
A. get the raw materials ready; Fast growing wood is sawn into the fast growing wood small powder of required specification, adjusts fast growing wood small powder moisture content to 5-12%;
B. mortise; Two opposite flanks at fast growing wood small powder width make tongue-and-groove, joint tongue, and applying glue;
C. piece together long assembly wide; Sized fast growing wood small powder is at the length direction spreading, wide in the assembly of fast growing wood small powder width, make blanket;
D. blanket sanding and cutting edge; Blanket is carried out two-sided sanding and washed ore to required flatness;
E. charing is processed; Blanket is carried out charing process, carbonization temperature is 160-230 ℃, carbonization time 2-5h;
F. compression molding is processed; Blanket after utilizing the cope match-plate pattern of hot press and lower bolster to charing is suppressed, and cope match-plate pattern and lower bolster temperature are 140 ℃-200 ℃, and the 1-3 ℃ of temperature difference, pressure are arranged between cope match-plate pattern and the lower bolster
0.05-0.13Mpa/ ㎡, press time 10-40min.
Manufacture method of the present invention, the fast growing wood finger-jointed plate good stability of making, structural strength is high, three-dimensional pattern is to be obtained by the template high temperature compacting with three-dimensional pattern, high temperature hot pressing can make compression section fix, avoid in use occurring resilience, affect stereoeffect, compress after elder generation's charing, simplify work flow, improved volume recovery, improved production efficiency, more can avoid after the hot pressing again charing on the impact of wood color, be that decorative effect is better, the moisture content between each fast growing wood small powder is controlled, problem on deformation occurs after can preventing from being spliced into finger-jointed plate, temperature difference between the bolster can make the whole plate of large format both sides consistent at press feeding process suffered heat before finish closure, avoid causing because of the feeding time difference moisture content difference of whole plate both sides, cause being out of shape after the product hot pressing, this further improves its dimensional stability, seam crossing does not have glue to shrink the depression that forms, and has reduced the use amount of glue yet.
As preferably, in described step B, institute's applying glue prescription is as follows:
Glue 99-99.7 part;
Microspheres 0.05-0.1 part;
Silicon ash 0.15-0.55 part;
Iron powder 0.1-0.35 part.
How to connect fastening between the fast growing wood small powder be in the industry a difficult problem always, existing mode all is to rely on glue to bond in the industry, in order to obtain the better bond effect that compares, processing request to adhesive surface is very high, even like this, effect is not still advanced people's will, the applicant is through repetition test, find after the research, in common glue, add an amount of microspheres, silicon ash and iron powder, utilize microspheres expansion at a certain temperature, it is large that volume becomes, so that joint tongue is connected connection with tongue-and-groove more fastening, silicon ash and iron powder can be filled up the gap after microspheres expands, and simultaneously, iron powder can also thrust in the fast growing wood small powder, further strengthen connecting effect, seam crossing does not have glue to shrink the depression that forms, so that the finger-jointed plate fastness of making is very good, avoids the inconsistent seam step that causes of interface resilience and the quality problems of rat yet.
As preferably, described microspheres diameter is 2-3 μ m, and described silicon ash average grain diameter is at 0.1-0.3 μ m, and described iron powder is the impalpable powder of 5-10 μ m.
As preferably, in the described step F, by cope match-plate pattern, lower bolster before compacting to blanket preheating 1-15min, and then compacting.
The contact preheating is in order to make timber fully softening, so that heat pressing compact and compression molding can be finished in a step, to have improved volume recovery, guaranteeing pressing result.
As preferably, among the described step B, also make tongue-and-groove, joint tongue in two opposite flanks of fast growing wood small powder length direction, and applying glue.
Like this, the fast growing wood small powder also is joggle at length direction when being spliced into finger-jointed plate, has just realized the four-way joggle of length direction and width, so that finger-jointed plate is more firm.
As preferably, in the described step F, cope match-plate pattern and lower bolster temperature are 160 ℃-180 ℃, and 1.5 ℃ of temperature difference, pressure are arranged between cope match-plate pattern and the lower bolster
0.1-0.13Mpa/ ㎡, press time 20-30min.
As preferably, in the described step F, by cope match-plate pattern, lower bolster before compacting to blanket preheating 5-10min, and then compacting.
As preferably, in the described steps A, the moisture content deviation is no more than 2% between the fast growing wood small powder.
