Description

The plate furniture bottom coloring Coating technology that paint uses can be effectively reduced

Technical field

The invention belongs to technical field of furniture manufacturing, more particularly, to a kind of plate furniture for effectively reducing paint and using Bottom coloring Coating technology.

Background technology

The plank of wood furniture needs to smear last layer bottom coloring first in process, and bottom coloring can make plank Surfacing is without recess, and adhesive property is good when finishing coat is put on bottom coloring, will not when finishing coat is applied on bottom coloring Fall paint etc.；But its processing technology existing defects, bottom coloring thickness low LCL cause plate surface in existing bottom coloring process There is hollow, to when upper finishing coat, need a large amount of finishing coat to fill up hollow, to reach the smooth effect of furniture surface Fruit；But because the usage amount of finishing coat is big, the substances such as toluene that the cost of furniture also just improves, and contains in finishing coat therewith, Indoor environment is influenced huge.

Invention content

The present invention for overcome the deficiencies in the prior art, provides a kind of plate furniture bottom for effectively reducing paint and using Color coating finish technique.

To achieve the goals above, the present invention uses following technical scheme：A kind of plank for effectively reducing paint and using Furniture bottom color coating finish technique, includes the following steps：

1) plank pre-processes：It is smooth that plank is slightly polishing to using 24# sand paper, then uses wet cloth

Wipe plank；It is carefully polished plank using 180# sand paper, then dedusting air-dries for use；

2) plank oil removing：Using impregnating plank in the sodium carbonate liquor of 5%-8%, when immersion

Between be 5-8 hour, impregnate after the completion of using clear water flushing 0.3-0.8 hours；

3) plank japanning：Roll coating apparatus will be adopted along plank ridge orientation priming, japanning number is 4-6 times, japanning thickness For 0.2-0.5mm；

4) plank is dried：Plank is dried 2-4 minutes using 200-350 DEG C of high temperature, then uses 60-95 DEG C of low temperature to plate Material is dried 16-28 minutes, then blows plank to room temperature using room temperature cold wind.

The present invention by it is thick, carefully polish twice so that plank integrally tends to be smooth, ensures that plank flatness is high, avoids bottom Paint is gathered at one, reduces the use of priming paint, similarly after meticulous polishing, the basic no concave-convex in surface, therefore rear The dosage of finishing coat can be reduced during continuous upper finishing coat；It can effectively be removed on plank using the sodium carbonate liquor of 5%-8% Grease, ensure Nian Jie close between bottom coloring and plank, avoid that situations such as occurring paint in the process, and 5%- is used for a long time Its alkalinity of 8% sodium carbonate liquor is weak, small to plank injury, and the quality of plank can also be ensured while oil removing；In japanning To 4-6 on bottom coloring, its one side can ensure that japanning is uniform in the process, and plank is avoided the case where holiday, and 4-6 times occur Japanning reaches expected thickness just, which has good scratch resistance, corrosion resistance, extends the service life of plank, and And adhesive effect is good between subsequent finishing coat and the bottom coloring, can adhere well on bottom coloring, and reach specified After thickness, the nonpitting situation of plate surface is realized substantially, reduces the dosage of finishing coat, and then reduce entire Furniture manufacturing Cost；During being dried to plank, 200-350 DEG C of high temperature can quickly evaporate most on priming paint Water so that priming paint is in leather hard, greatly shortens the time of the drying of priming paint, and priming paint will not also under the temperature range Occur rotten；And during subsequent 60-95 DEG C of low temperature drying, on the one hand it is the plastics for having ensured priming paint drying, it is another anti- The face temperature avoids priming paint and dry and cracked situation occurs, therefore priming paint can form coast of paint film in the temperature-rise period, effectively Plank is protected, drying at room temperature then contributes to the temperature of priming paint gradually to reduce, avoids quickly expanding with heat and contract with cold and causing to paint Film ruptures.

Further, the priming paint includes following components by weight percent：20-28 parts of amino resins, 8-12 parts of zinc powder, anti-settling agent 0.4-0.8 parts, 0.5-1.3 parts of preservative, 0.2-0.8 parts of film forming agent, surplus is deionized water.

Further, the film forming agent includes following components by weight percent：33-45 parts of glycidol ether, ethylene oxidic ester 20-28 Part, 6-12 parts of resin acid, sorb be stearic acid 6-12 parts smooth, 1.8-4.8 parts of mica powder, acrylic resin are modified casein filming agent 5- 10 parts, 0.2-0.8 parts of flame retardant.

Further, the roll coating apparatus includes holder, roller coating component and the drive for driving the roller coating component rotation Moving part；The roller coating component includes the smearing part and feed member that roll body and the roll body are detachably connected, and the roll body is equipped with One accommodating cavity, the feed member are at least partially disposed in the accommodating cavity；By be arranged roller coating component its can it is automatic to plank on During which without human intervention paint reduces manually old, the volatile materials on priming paint is avoided to damage personnel；Roller is set Body smears part and feed member, and it is continual to part feeding is smeared to realize feed member, ensures that the material smeared on part can be fast Speed effectively carries out japanning to plank, because roll body can rotate during being somebody's turn to do, therefore priming paint is uniformly smeared on plank.

Further, the feed member include be set to the accommodating cavity in first pipe and second pipe, described first Pipeline is flexibly connected with the second pipe by a connection structure；Feed member is set as first pipe and second pipe, to Second pipe can be rotated with first pipe when roll body rotates, and ensure roll body normal rotation, to ensure normal brush Paint.

Further, the connection structure includes connecting sleeve and at least two connections set on described connecting sleeve one end Ring, the second pipe are equipped with and the matched location indentations of the connection ring；One end is obtained in connecting sleeve, and two companies are set Ring is connect, is realized when second pipe rotates therewith, double-layer seal is done to connecting sleeve and second pipe, ensures that priming paint will not Leakage, moreover it is possible to ensure that second pipe is rotated synchronously with roll body.

Further, the connection ring is equipped with the wearing layer fitted closely with the location indentations bottom；It is arranged wear-resisting Layer avoids because of the case where abrasion gap occurs, liquid is caused to reveal between second pipe and connection ring, which improves The service life of connection ring.

In conclusion the present invention effectively ensures plank overall leveling and oil-free by pretreatment and oil removing process, to During smearing finishing coat in the later stage, the dosage of finishing coat is reduced, reduces production cost, lacquer painting is not easily to fall off, and service life is long.
