Description

The processing method that is used for the printing base of melaminated paper

Technical field

The present invention relates to the thin paper of employing in multilayer or multiple layer decoration, and their manufacture method.

The present invention more specifically relates to the printing base that expection is used for the melaminated paper (papiers m é lamin é s) of production floor or top-grade furniture.

Background technology

According to desirable application of finished product and manufacturing cost, on market, formed the paper of two kinds of series: " polishing paper (feuilles finies) " and " melaminated paper ".

Polishing paper is such paper: after making, it is placed converter continuously in the papermaking device, utilize binder film to adhere on the desirable supporter (such as panel), and decorate in printer then.If do not take extra step in their manufacture method, they will be known as " and paper (papier japonais) " and their poundage (with gm so ^-2Weight for every square metre of cardboard of unit) at 20gm ^-2With 50gm ^-2Between.This paper has good cohesive force and significant smoothness, but makes it possess impressionability and sprayability, but its change and its bonding be fragile because it tends to heave (with respect to the distortion of flatness).

Also can adopt extra step, during these extra steps, perhaps by the size presser (situation of pre-preg, cardboard will have less warpage but higher cost and unlike with paper level and smooth), perhaps in the converter (situation of back dipping, owing on different machines, continue this method, the manufacturing cost of cardboard is higher) in, mixture with synthetic latex and thermosetting resin comes impregnated paper, size presser is a kind of double spread device with roller, roller is positioned on the paper machine, be made up of a pair of stacked cylinder, and is that this layout to stacked cylinder can be level or tilt.

In size presser, paper passes the dipping bath that is formed between each cylinder and the cardboard.In such machine, the accurate amount on the paper of being deposited on is uncontrollable and the amount that is penetrated into the refill degree of depth also is uncontrollable.

In addition, because this machine has the charging of unique dipping bath, thereby can not on the opposite side of cardboard, realize different depositions.

In addition, even can realize the introducing of different product, but passing the fact of whole dipping bath, paper make this different deposition become impossible, because during dipping two kinds of products can mix in refill.

However, the physical characteristics of the polishing paper that obtains does not so allow them to be used for all types of application.They are suitable for making the panel that is used for low-grade furniture, vertical surface etc., but the repellence of their impact, wearing and tearing, heat, liquid, light and chemical products is relatively poor.

When these characteristics of needs, during such as high-quality floor of production or furniture, preferably or by low-voltage technology or by high pressure technique produce melaminated paper.

These melaminated papers comprise:

-decorative panel,

-overlay, it is given and piles up specific strength characteristic, and the protection decorative panel avoids staiing, weares and teares and scraping.

Preferably, the cellulosic material that overlay comprises is free from foreign meter, opacity is lower, it comprises coloring earth according to circumstances, and coloring earth can increase its abrasion resistance and hardness.Select pigment to make after dipping, do not cause any color to occur in multiple layer paper, perhaps causing increases any opacity, and these phenomenons will be covered the pattern that is printed on lower floor's decorative panel.

Overlay has about 20 usually to 40gm ^-2Poundage, behind dipping, poundage is increased to 75-100gm ^-2

In the low-voltage technology process, use based on thermosetting resin and mixture of catalysts and flood decorative panel and overlay, by the low pressure squeezer it is applied on the panel then and (applies balance plate usually at the back of panel) to make formed complex stable dimensionally.Resin is in the interior diffusion of piling up of plate then, and makes them adhere on the panel securely.

Different with melaminated paper, polishing paper can not be made in low-voltage technology (high pressure technique): their constituent material and their processing do not allow with resin they to be carried out best dipping.Here it is utilizes binder film that polishing paper is applied to reason on the supporting faceplate that they will decorate.That but this technical scheme does not provide is anti-scratch, enough surfaces characteristic of wearing and tearing, so that can not use in the application of floor, work top and top-grade furniture.

For example, document EP 0 870 872 has been described a kind of method that is used to obtain polishing paper mold thin paper, wherein, pigment (by binding agent) is applied on the print surface or sprayed surface of paper, and this face is with relative with the coating of impregnating resin dipping.But during this period with respect to unprocessed paper, paper is no more than 5% to 30% to being absorbed in of resin on the weight, and employed paper is not used for flooding usually in making polishing paper.In addition, owing on printing surface, do not have resin, so it does not have any specific DIMENSIONAL STABILITY.

Compare with polishing paper, melaminated paper has resistance to wearing of bigger DIMENSIONAL STABILITY and enhancing and scratch.This is their preferred reasons in such as the application of production floor and top-grade furniture.

During high pressure technique, also overlay is applied on the decorative panel.But, different with low-voltage technology, one or more kraft liners are placed the below of decorative panel.Then, utilize resin to flood the complex of such formation, be placed on afterwards in the squeezer, squeezer applies high pressure (and high temperature) to obtain the sandwich of high density and high rigidity to it.

The cost of high-voltage paper exceeds 30% to 40% than the cost of the multiple layer paper that obtains by low-voltage technology.They for example are used for the production work table top.Their mechanical performance, promptly their moisture resistance or their temperature stability and they resistance to wear and scratch better.

This is to be the reason that purpose is carried out many researchs to produce printing base according to low-voltage technology, and this printing base cost is lower, and its feature class is similar to the printing base by high pressure technique acquisition, and its poundage is lower.

For this angle, patent application WO 02/079571 has for example described a kind of low pressure method of under low pressure making the printing base, wherein, will comprise that the mixture of formaldehyde resin, acrylic latex and curing agent is coated on the upper surface, and be coated on the lower surface alternatively then.This method can be reduced to 15gm with the poundage of paper ^-2With 60gm ^-2Between, reduce the amount of impregnating resin equally, improve the mechanical features of the printing base that is obtained simultaneously.But this method need use two or three continuous steps to flood these layers, compares with the prior art level, and this has increased its manufacturing time and cost, but does not improve press quality.

Be that in the purpose of patent application WO 01/21892 a kind of manufacturing is used for method with the paper of synthetic resin dipping, this method is applicable to low-voltage technology and high pressure technique, may further comprise the steps: use the first mixture A to come impregnated paper based on resin, then, apply the second mixture B based on resin simultaneously, the second mixture B is preferably identical with mixture A.After drying steps, at least one face in these faces applies the 3rd mixture C based on resin then, and the 3rd mixture C preferably has the composition identical with mixture A.By the pre-treatment step of this method, the paper that is obtained has more high-quality printing performance (rendu d ' impression).But this method needs many production stages, and therefore causes the increase of its manufacturing cost.

Summary of the invention

Description of drawings

Referring to accompanying drawing, by reading detailed description hereinafter, other characteristics of the present invention, purpose and advantage will become apparent, and accompanying drawing provides as limiting examples, and in the accompanying drawings:

Fig. 1 illustrates according to the present invention and utilizes injection nozzle to come varnished pressboard,

Fig. 2 is the sectional view of Fig. 1.

The specific embodiment

As seeing, resin floor comprises decorative panel, overlay, based on (MDF (medium density fiber), HDF (high-density fiber) etc.) panel and overlay of particulate.The present invention relates to improvement, if this overlay of words that needs is applied by converter as the processing method of the paper of the printing base (decorative panel) of melaminated paper.

For this reason, at first produce the supporting paper based on refining a little fiber, Jing Zhi fiber comprises the mixture of the short fibered pulp (hardwood) of the long fiber pulp (cork) of 50-20% weight and 50-80% weight a little.

Long fiber is represented the fiber of 3-5mm, from such as pine tree, dragon spruce, pine or pesudotsuga taxifolia.Approximately the short fibered pulp of 1-2mm is from for example eucalyptus, locust tree, maple, birch or chestnut.

The special component of selecting this mixture is to form supporter, and this supporter is particularly suitable for the resin that will coat on the paper its core being flooded.

In fact, the percentage of staple fibre (50-80%) allows to improve the formation of plate, and long stapled percentage (50-20%) forms grid (canvas), utilizes staple fibre to fill its hole, and this generation is suitable for the porosity that resin is filled the supporter of core.

For example, if produce the paper that comprises 70% eucalyptus fibers and 30% pine tree fiber, the poundage that supports paper so will be at 40-43gm ^-2Between.

In supporting paper, also there is pigment known in the industry, so that paper possesses certain whiteness (with the contrast of optimize decorating) and sufficient opacity are seen pattern or plate with the thickness that prevents to pass (seeing through) paper defective.For example, can recently use titanium oxide TiO according to 10% to 30% percentage of the quality of paper ₂Select to give the grade of good ageing stability of material and photostability then.

According to the present invention, also add such as kaolinic coloring earth to paper, with the further opacity of improving paper (decide on pigment, account for drying the paper substrate quality 0% to 20%).Coloring earth is actually the excellent material of filling between fiber.

The minuent of the interpolation binding fiber compound of these pigment is refining, causes supporting the high porosity level (air permeability＜20s) for example of paper substrate.

In this stage, also can add the additive that improves the strength of materials, such as polyamide-epoxychloropropane (PAE) resin, account for 0.1% to 1.5% ratio of dry paper substrate quality, it is for being used for the known agent of strength characteristic under the hygrometric state in the papermaking.

Preferably, in manufacture process, the pH value of fibrous suspension is kept the pH neutral near the moist part of machine, crosslinked with the facilitating impregnation resin.

Therefore, manufacture method all carry out in the alkalescent of the pH value between corresponding to 6.5 and 7.5 or the weak acidic medium in steps.Its purpose is to increase the cross-linked speed of resin, and this is a key element important in this method, because this method is prepared head at the paper machine resin in conjunction with maximum in paper, and the resin that importantly is accumulated in when paper tape leaves paper machine in the paper is crosslinked fully.

Now understood the crosslinked faster in neutral basically medium of resin.Because resin be alkalescence (the pH value is between 7.7 and 8.5) relatively, so importantly the paper pulp bathroom facilities has pH value between 6.5 and 7.5 with in best and resin, thereby improves its cross-linked speed.

The method according to this invention utilizes " film press machine " or " film sizing applicator " to implement directly to be formed at the different coating of the paper on the paper machine.Deposit two kinds of different compositions simultaneously on the upper surface (its corresponding to will with the surface of overlay contact) that this different coating is included in paper and the lower surface (it will contact with panel).

Film press machine or film sizing applicator are to use the worm screw 3a, the 3b that are called " pencil " or the double spread device of blade, are used for promoting the coating composition in a controlled manner on

coating pressure roller

2a, 2b.

Illustrated in the accompanying drawings, it comprises two

squeezer roller

2a and 2b, two

worm screw

3a and 3b, and two

discharge dish

4a and 4b, and they are with respect to the location, plane symmetry ground of paper 1.Their longitudinal axis is parallel to each other and extend perpendicular to the direction of travel 10 of paper 1.

Place the roller 2a of a side of paper 1 to allow on the direction of direction of travel 10, to drive paper 1 against second roller 2b compressing paper 1.

Each

worm screw

3a, 3b contact with corresponding roller 2a, 2b.The deposition volume principle relevant with the diameter wiry of spiral winding roller 3a-3b makes it possible to accurately control the volume of every kind of deposition composition.

In addition, recovering

tray

4a and 4b are positioned the below of

worm screw

3a and 3b respectively, to reclaim and every kind of excessive resin compound of recirculation., each

dish

4a, 4b are connected on the corresponding recirculation circuit, with the composition of considering individually to collect in each side of paper for this reason.

The poundage that is coated to the composition of the coating on the lower surface account for paper final poundage 20% to 40% between, this composition comprises:

-such as kaolinic at least a coloring earth, its account for dry ingredient weight 0% to 40%, be preferably 28%.

Certain porosity is kept in itself thereby permission on finished paper, this will improve the quality of dipping subsequently.

-thermosetting resin, itself or be the urea formadehyde resin, account for 30% to 80% of dry ingredient weight, preferably 36%, perhaps being modified acroleic acid, melamine, acetaldehyde, formic acid urea resin, perhaps is the another kind of resin of release formaldehyde not between crosslinked and dry period at it.

These resins can be from being selected by the urea resin knot cement (Kaurit) of the various series that BASF proposed.When the diffusion on the supporting faceplate that is applying paper by resin came binding resin, the resin of following coating aimed to provide the delamination resistance of paper, also increased the cohesive force of material simultaneously and made it sclerosis.

-synthetic latex, account for dry ingredient weight 20% to 50%, be preferably 36%, such as styrene acrylic latex with glassy state transition temperature Tg above 20-25 ℃.

This latex is actually self-crosslinking, and different with resin, and it gives material flexibility avoiding making it crisp,

-be used for the catalyst of resin, account for used resin quality 0.2% to 5%.Certainly, selection of catalysts depends on the thermosetting resin that constitutes this coating.

Therefore, for the urea formadehyde resin, will select curing agent based on inorganic salts for catalyst, and if selected modified acroleic acid, melamine, formic acid urea resin, then catalyst will can be p-methyl benzenesulfonic acid (ATPS).

For the preferred percent of above being mentioned, then descend coating will have the poundage of the poundage 27% of the decorative panel of accounting for (that is basic paper).

Owing to this concrete composition of the following coating of paper has obtained a kind of paper, its DIMENSIONAL STABILITY significantly improves.In fact resin compound is coated on the fiber, thereby anti-sealing is penetrated into the in-core of network of fibers.Used catalyst promotes this hydrophobicity.In fact it play the effect of the not solvent of thermosetting resin by the WATER RESISTANCE that increases handled paper.

Therefore, in its printing and transition period, although the humidity level changes, anyly widening or shrinks the percent defective when this has reduced to produce end does not significantly appear in paper.In fact, in final operating process, resin panel is cut into band (promptly, the band of supporter, on this supporter, impregnated melaminated paper and balance plate combine by pressure on squeezer), if paper experience during its conversion or printing is shunk or is stretched, excision will not carried out on preprinted line of cut on the paper, but carries out in the outside of preprinted line of cut, and this can make it to scrap immediately.

As a comparison, according to the MUTEK test that stability is expressed as the percentage elongation percentage in the humid medium, the DIMENSIONAL STABILITY level of paper that the method according to this invention obtains is 0.5%, and the level of stability of standard paper is 2.5% to 3%.

The composition that is coated on the coating on the upper surface is according to 2gm ^-2To 10gm ^-2Be deposited on the paper, this composition comprises:

-such as kaolinic at least a coloring earth, account for dry ingredient weight 60% to 95%, be preferably 88%,

-modified acroleic acid, melamine, the formic acid urea resin, account for dry ingredient weight 5% to 40%, be preferably 12%, be selected from the Kaurit series that proposes by BASF, perhaps the resin of release formaldehyde not between crosslinked and its dry period at it.

This resin is used as the binding agent of partly locating at the pigment of coating, and compatible with coated impregnating resin of transition period.

-be used for the catalyst of resin, account for 0.2% to 1% of used resin quality, such as p-methyl benzenesulfonic acid (ATPS).

This special component that is deposited on the last coating on one-sided (face that will print) of paper has increased the press quality of finished paper.

This strong pigment coated special properties is feasible to obtain high smoothness level, and therefore obtains fabulous surface state, and extraordinary printing performance.

In fact, such as the existence of the such coloring earth of kaolin, the size of its particle and shape make pigment be particularly suitable for this application, with calendering step combination subsequently, better smoothness are provided for last coating.Thereby contacting between print head and the paper become more even, thereby can obtain to have the image of bigger optical density (OD) and more regular contrast.

Thereby for the ink of equivalent, the printing performance is better; And for suitable printing performance quality, can reduce used quantity of ink, this causes the printing cost saving.

Certainly also can use other pigment, such as titanium dioxide (TiO ₂) or calcium carbonate (CaCO ₃)

The poundage that obtains finished paper is at 56gm ^-2With 60gm ^-2Between.

For mentioned preferred mass percentage during the description preferred embodiment, comprise the basic paper that is covered by above-mentioned coating and last coating down, the poundage separately of coating equals 40-43gm ^-2, 12gm ^-2And 4gm ^-2To 5gm ^-2

And because the following coating of paper and the concrete composition of last coating, the DIMENSIONAL STABILITY of paper is better than the DIMENSIONAL STABILITY of prior art products.

In fact, the resin of coating is penetrated into the in-core of paper under constituting owing to its character, keep from the teeth outwards and the resin of the last coating that is associated with pigment is most of, thereby during printing, make ink in the thickness of paper, not dilute, thereby can keep strong print distinctness.

Continue dry so step of the paper of coating then, in soft calender, carry out surface treatment afterwards.

Soft calender is following calender: it comprises the roller that is coated with elastomeric material on the one hand and comprises the roller with crust on the other hand.By making paper pass hard roller and for example being coated with between the soft roller of polyurethane lining, can on the two sides of paper, apply different calendering pressure, keep the high opacity of paper simultaneously.

These steps also betide on the paper machine.

Preferably, surface treatment mainly is applied on the coating to improve its print characteristics, i.e. its smoothness.During operation, according to the present invention, can obtain to surpass the Bekk smoothness of 300s.

In the Bekk measuring method, air-spray vertically is applied on the cardboard that is laid on the solid supporter.The Bekk measuring method is measured the air leak on paper surface, and this provides the measurement of cardboard smoothness.In such measurement, the very high smoothness level of big coefficient representative.In application type involved in the present invention, the high-quality smoothness of coefficient 300 expressions.

At last, the paper that obtains like this is applied on the required panel such as floor panel or floor, places balance plate usually so that the complex that forms is stable dimensionally like this at the rear of paper.

After utilizing the known resin dipping, under the temperature between 105 ℃ and 225 ℃, utilize the low pressure squeezer in the time span that can be between 30 seconds to 40 seconds to comprising that piling up of facing paper, overlay, panel and balance plate applies about pressure of 2.1 to 2.8MPa.In this step process, the impregnating resin in piling up spreads and makes overlay transparent.

By on the upper surface of paper and lower surface, applying special component, in the low-voltage technology process, can reduce amount (be used to flood overlay and by printing base that this method obtained) at required impregnating resin of paper transition period.

Owing to utilize the film press machine when this method begins, a large amount of resins that are derived from down coating are in the core existence of layer structure, and this will allow to reduce required amount of resin, even make resin penetration in paper and make it become possibility during finally flooding after printing.

In addition, as the direct result that reduces the impregnating resin amount, also reduced the poundage of the melaminated paper of final acquisition pro rata.

And the reduction of poundage and impregnating resin amount mechanically causes the poundage of balance plate and dipping to reduce pro rata.

In fact, when making multiple layer floor, balance plate must have equal to be applied to the upper strata on the panel weight to prevent any distortion such as warpage of paper and panel.

It will be understood by a person skilled in the art that, compare with the method for prior art, can in single industrial operation, make the printing base that is used for melaminated paper according to low-voltage technology, this printing base combines the DIMENSIONAL STABILITY of the melaminated paper that is higher than prior art and higher press quality in its printing and transition period.

This method according to the present invention combines the certain benefits of different product, and this is that prior art can not make up on identical product in single step.

In addition, those skilled in the art will understand the low pressure method that a kind of making is used for the printing base of melaminated paper, compare with known method in this field, its production cost reduces, because all operations is being carried out during single industrial process on the single paper machine, rather than carry out with discontinuous process, discontinuous process need is positioned at the participant of diverse location, with load interrupt, transportation, middle loss and deposit temporarily.

The paper tape that is used to make the printing base that the present invention also obtains at the method according to this invention is coated with the mixture based on resin, and is coated with the mixture based on resin that is different from first mixture on their lower surface on their upper surface.

The mixture of coating on the lower surface based on resin comprises, accounts for the composition weight of drying composite:

30% to 80% resin,

20% to 50% latex,

The catalyst of 0.2% to 5% resin quality, and

0% to 40% pigment.

The mixture based on resin of coating upper surface comprises at least a resin, a kind of pigment and a kind of resin catalyst.

Resin can be modified acroleic acid as indicated above, resin, formic acid urea resin and resin catalyst will be p-methyl benzenesulfonic acid.

In another modification, resin can be at it between crosslinked and its dry period the not resin of release formaldehyde.

According to the present invention, the mixture of coating on the upper surface based on resin can comprise, accounts for the composition weight of drying composite:

5% to 40% resin,

The catalyst of 0.2% to 1% resin quality, and

6% to 95% pigment.
