Description
Technical field
The present invention relates to decorative materials technology, relate to a kind of manufacture method of the finger-jointed plate with concave-convex surface stereo relief effect in particular.
Background technology
Existing finger-jointed plate mostly is planar products, and decorative effect is single, the product with concave-convex surface stereo relief effect of minority, is also to do wire drawing process after making platelet by artificial electric planer or saw, and production efficiency is low, and effect of decorative patterns inconvenience controls.
According to the regulation of GB/T21140-2007, finger joint lumber refers to sawn timber to be that raw material is through referring to that tenon is processed, gummed spreading and the plate square bar made, after again the plate square bar made being bondd by glue in the direction of the width, finger-jointed plate is made in hot pressing, the raw material used is generally based on fast growing wood, wherein with poplar application at most, the side of plate square bar width is plane, difficulty of processing is large, after bonding, structural strength is low, so someone improves, such as application publication number CN102192395A, a kind of finger-jointed plate of disclosure of the invention shown in Shen Qing Publication day 2011.09.21, this finger-jointed plate comprises the finger bar be spliced by multistage sawtooth short slab, bonding plane between its finger bar is inclined-plane.The finger-jointed plate of this invention, by the bonding plane between finger bar is designed to inclined-plane, increases the bonding and lifting surface area between finger bar, makes finger-jointed plate firmly bonding and in use more not easy to crack.But, even if change the adhesive surface between finger bar into inclined-plane, after making finger-jointed plate, the stability of the whole plate of finger-jointed plate should be not, seam crossing is not tight, and easily after glue shrinks, occur depression, what these problems were serious constrains the application of finger-jointed plate in end product.
Summary of the invention
The object of the invention is for the deficiencies in the prior art part, a kind of manufacture method of the finger-jointed plate with concave-convex surface stereo relief effect is provided, its finger-jointed plate structural strength of making is high, and stability is good, can not occur the quality problems of step and rat at seam crossing.
In order to solve the problems of the technologies described above, technical scheme of the present invention is as follows: with the manufacture method of the finger-jointed plate of concave-convex surface stereo relief effect, comprise the following steps:
A. get the raw materials ready; Fast growing wood is sawn into the fast growing wood small powder of required specification, adjustment fast growing wood small powder moisture content is to 5-12%;
B. mortise; Tongue-and-groove, joint tongue is made in two opposite flanks of fast growing wood small powder width, and applying glue;
C. long spelling is spelled wide; By sized fast growing wood small powder at length direction spreading, spell wide at fast growing wood small powder width, make blanket;
D. blanket sanding and cutting edge; Blanket is carried out two-sided sanding and washed ore extremely required flatness;
E. process is carbonized; Blanket is carried out charing process, carbonization temperature is 160-230 DEG C, carbonization time 2-5h;
F. compression molding process; Utilize the cope match-plate pattern of hot press and lower bolster to suppress the blanket after charing, cope match-plate pattern and lower bolster temperature are 140 DEG C-200 DEG C, and have the 1-3 DEG C of temperature difference between cope match-plate pattern and lower bolster, pressure
0.05-0.13MPa, press time 10-40min.
Manufacture method of the present invention, the fast growing wood finger-jointed plate good stability made, structural strength is high, three-dimensional pattern is suppressed by the template high temperature with three-dimensional pattern to obtain, high temperature hot pressing can make compression section fix, avoid in use occurring resilience, affect stereoeffect, first carbonize and compress afterwards, simplify work flow, improve volume recovery, improve production efficiency, the impact on wood color is carbonized again after more can avoiding hot pressing, that decorative effect is better, moisture content between each fast growing wood small powder is controlled, problem on deformation is there is after can preventing being spliced into finger-jointed plate, temperature difference between bolster can make large format whole plate both sides press feeding process to complete closed before suffered heat consistent, avoid because the feeding time difference causes the moisture content difference of whole plate both sides, be out of shape after causing product hot pressing, this further improves its dimensional stability, seam crossing does not have glue to shrink the depression formed, decrease the use amount of glue.
As preferably, in described step B, institute's sizing formulation 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 make to connect between fast growing wood small powder fastening is a difficult problem in the industry always, existing mode is all rely on glue to bond in the industry, in order to obtain the good bond effect that compares, very high to the processing request of adhesive surface, even if like this, effect does not still enter people's will, the applicant is through repetition test, find after research, appropriate microspheres is added in common glue, silicon ash and iron powder, utilize microspheres expansion at a certain temperature, volume becomes large, make the connection of joint tongue and tongue-and-groove more fastening, gap after microspheres of can filling up silicon ash and iron powder expands, simultaneously, iron powder can also thrust in fast growing wood small powder, further reinforcement connects effect, seam crossing does not have glue to shrink the depression formed, make the finger-jointed plate fastness made very good, also the quality problems of the inconsistent seam step that causes of interface resilience and rat are avoided.
As preferably, described microspheres diameter is 2-3 μm, and described silicon ash average grain diameter is at 0.1-0.3 μm, and described iron powder is the impalpable powder of 5-10 μm.
As preferably, in described step F, by cope match-plate pattern, lower bolster before pressing to blanket preheating 1-15min, and then suppress.
Contact preheating is to make timber fully softening, heat pressing compact and compression molding a step can be completed, improve volume recovery, ensures pressing result.
As preferably, in 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, fast growing wood small powder, when being spliced into finger-jointed plate, is also joggle at length direction, just achieves the four-way joggle of length direction and width, makes finger-jointed plate more firm.
As preferably, in described step F, cope match-plate pattern and lower bolster temperature are 160 DEG C-180 DEG C, and have 1.5 DEG C of temperature difference between cope match-plate pattern and lower bolster, pressure
0.1-0.13MPa, press time 20-30min.
As preferably, in described step F, by cope match-plate pattern, lower bolster before pressing to blanket preheating 5-10min, and then suppress.
As preferably, in described steps A, between fast growing wood small powder, moisture content deviation is no more than 2%.
Beneficial effect of the present invention is:
Manufacture method of the present invention, technique is simple, and its finger-jointed plate structural strength of making is high, and stability is good, can not occur the quality problems of step and rat at seam crossing.
