Abstract

A technology for producing printed plywood includes such steps as abrasing one surface of plywood, coating atomic paint, baking, cooling, abrasing, painting, baking, cooling, printing, baking, coating U.V colloid, ultraviolet baking and cooling. Its advantages include low cost and high grade and quality of product.

Description

The production method of printed plywood

The invention belongs to the wood processing technique field, refer more particularly to the production method of printed plywood.

Often there is flaw on the surface of glued board, is not suitable for direct material as furniture or building; Be through veneer now, promptly select the surface that smooth wooden fine sheet attractive in appearance is fitted in glued board, cost is higher, and it is used furniture or architectural after, its surface also need be done japanning and handle, and gives out irritating smell indoor.

The production method that the purpose of this invention is to provide a kind of printed plywood, its production cost is lower, good product quality, the japanning of unnecessary row again.

The object of the present invention is achieved like this:

A kind of production method of optimizing the printed plywood of its quality on the basis of successively being glued together the hardboard material that forms by wooden sheet mutually is characterized in that: to the minimum one side of above-mentioned hardboard material, carry out successively:

A. carry out sanding repeatedly successively, apply atomic glue, oven dry, cooling, to this table

The flaw of face is filled and led up;

B. above-mentioned surface is carried out sanding repeatedly successively, applies paint, is dried, cools off,

Evenly cover the color of above-mentioned hardboard material and atomic glue to painting color;

C. print on the surface of the rapid gained of previous step, then oven dry; With

D. at the surface-coated U.V glue of the rapid gained of previous step, dry, cool off with ultraviolet ray then.

As from the foregoing, the inventive method is simple, owing to have good machinery and optical property after the U.V adhesive curing, make good product quality, outward appearance is beautiful, and the higher wooden fine sheet smooth attractive in appearance of price does not need again to fit again, reduced cost, the japanning of unnecessary row again, it is also comparatively convenient to use.

Introduce one embodiment of the present of invention below in conjunction with accompanying drawing:

Fig. 1 is the flow sheet of the production method of a kind of glued board of the present invention.Among Fig. 1: the 90th, hardboard material, the 100th, printed plywood; 1001, the 1002nd, Rule of judgment, wherein the former judges that " surface blemish of hardboard material is filled and led up ", the latter are to judge " color that paint evenly covers hardboard material and atomic glue "; All the other are code names of operation, and wherein 91 is sandings, the 92nd, apply atomic glue, and the 93rd, the dry saturated steam oven dry, the 94th, the cool breeze cooling, the 95th, leave standstill, the 96th, printing, the 97th, apply U.V glue, the 98th, the ultraviolet ray oven dry, the 99th, apply paint.

Fig. 2 is the schematic diagram of production line of the production method of a kind of printed plywood of the present invention.Among Fig. 2, the 21st, lifting platform, the 22nd, conveyer, the 23rd, sander, the 24th, atomic glue coating machine, the 25th, dry saturated steam dryer, the 26th, cool breeze cooler, the 27th, paint application machine, the 28th, cross conveyor, the 29th, printing machine, the 210th, U.V glue coating machine, the 211st, ultraviolet dryer, the 212nd, product platform.

Fig. 3 is the schematic diagram with the product of method production of the present invention.

As shown in Figure 1, a kind of production method of optimizing the printed plywood of its quality on the basis of successively being glued together the hardboard material that forms by wooden sheet mutually of the present invention is characterized in that: to the minimum one side of above-mentioned hardboard material, carry out successively:

A. carry out sanding repeatedly successively, apply atomic glue, oven dry, cooling, filled and led up to this surperficial flaw;

B. above-mentioned surface is carried out sanding repeatedly successively, applies paint, dried, cools off, evenly cover the color of above-mentioned hardboard material and atomic glue to painting color;

Except that " ultraviolet ray oven dry ", above-mentioned said " oven dry " is the dry saturated steam oven dry, and its vapor (steam) temperature is about 120 degree; Till the moisture content that its glued board is all dried in all oven dry reaches between the 6-14%.

As shown in Figure 2, hardboard material 1 is placed on the lifting platform 21 that A orders, being transferred machine 22 delivers to sander 23 and carries out sanding, be transferred machine 22 then and deliver to two atomic glue coating machines, 24 twice coating atomic glue successively, dried through three sections dry saturated steam dryers 25 again, arrive cool breeze cooler 26 again, arrive the B point, be cooled to normal temperature; Carrying out repeatedly between the above-mentioned steps a, gained hardboard material 1 was left standstill about 24 hours or more than; Return the A point again, repeat above-mentioned process of ordering to B, need usually three times by the A point; Then

Hardboard material 1 is placed on the lifting platform 21 that C orders, being transferred machine 22 delivers to sander 23 and carries out sanding, be transferred machine 22 then and deliver to 27 4 coating paint of four table oils lacquer coating machine successively, dried through dry saturated steam dryer 25 again, arrive cool breeze cooler 26 again, be cooled to lower temperature, arrive the D point through cross conveyor 28: above-mentioned process of ordering to D by the C point, usually only need once, has only the hardboard material 1 that does not reach above-mentioned " painting color evenly covers the color of above-mentioned hardboard material and atomic glue " through check, just picked out, put back to the C point, repeated above-mentioned process of ordering to D by the C point; Then

Hardboard material 1 is transported to by cross conveyor 28 and is right after on the conveyer 22 that D orders, and is transported to printing machine 29, is printed on designed pattern, is dried through dry saturated steam dryer 25 again, arrives cool breeze cooler 26 again, is cooled to lower temperature; Then

Hardboard material 1 is transferred machine 22 and is transported to U.V glue coating machine 210, coated U.V glue, be transferred machine 22 then and be transported to ultraviolet dryer 211, U.V glue solidifies under action of ultraviolet ray, arrive cool breeze cooler 26 again, be cooled to lower temperature, be transferred machine 22 again and be transported to product platform 212, can put in storage, dispatch from the factory and sold through the passer.

As shown in Figure 3, the printed plywood that method of the present invention is produced, be in the minimum one side (above being illustrated as) of successively gluing together the hardboard material 1 that forms by wooden sheet 11 mutually, be coated with the coating of atomic glue 2, paint 3 and U.V glue 4 successively, and below the coating of U.V glue 4, be printed with designed pattern.

This specification said " U.V glue " claims " U.V ultraviolet cured flame-retardant resin " again.
