Definitions
- the present invention relates to a water-dispersible hot melt composition, a disintegratable moisture-proof paper using the composition, and a method for producing the same.
- moisture-proof paper is well known as a paper obtained by coating a paper with an olefin resin such as polyethylene or polypyrene D-pyrene.
- the moisture-proof paper coated with this olefin resin is excellent in moisture-proof property, not only excellent in workability, but also inexpensive, and extremely excellent as a moisture-proof paper.
- the moisture-proof layer has too high a coating strength, so that the pulp used in the process of recycling and pulping paper separates from the fiber part of the paper.
- the refined resin layer does not disperse finely and remains as a lump film, which adheres to the drying roll of the paper machine or adheres to the surface of recycled paper, causing bleeding and unevenness to recycle waste paper Is impossible.
- the coating liquid is emulsion
- a long drying equipment is required to form the coating, and the productivity is lower than that of coating with the olefin resin. bad.
- drying proceeds, and as the film of the moisture-proof layer is formed, a force is generated on the moisture-proof paper, wax in the coating liquid bleeds, and slippage occurs on the moisture-proof paper. Therefore, there is a problem that the number of steps must be increased on the back side of the emulsion coated type moisture-proof paper for the purpose of curling prevention and slip prevention.
- the obtained moisture-proof paper is included in the moisture-proof layer because the surface of the moisture-proof layer comes into contact with the opposite side (the back side of the paper base material) where the moisture-proof calendar is not provided when it is wound up on the coil.
- the wax component is transferred to the opposite surface, making it extremely slippery, blocking, and the problem of being unable to print with water-based ink.
- a moisture-proof calendar is formed on the surface of the emulsion-coated surface, for example, if an emulsion paste is used during packaging, the emulsion paste will not be able to be applied successfully by repelling the emulsion paste, or even if it can be applied, it will not adhere to the moisture-proof layer. As a result, the adhesive strength is not practical. For this reason, only hot-melt glue can be used as an adhesive when packaging with these moisture-proof papers, and there is a problem that the use of the moisture-proof papers is extremely limited.
- the hot melt moisture proofing sandwiched in the above-mentioned sandwich shape may be superposed in multiple stages (paper / hot melt moisture proof layer / paper / hot melt moisture proof layer / paper, etc.).
- the hot melt composition may be further provided with a moisture barrier on both sides.
- the present invention solves the above-mentioned drawbacks of the prior art, has excellent moisture proof properties, has excellent recycling properties for waste paper, is inexpensive and has excellent productivity, and furthermore has excellent slip resistance and roll components during winding.
- the purpose of the present invention is to provide a moisture-proof paper having an improved transfer of water, a moisture-proof paper having an improved adhesiveness, and a moisture-proof paper having a polysand finish.
- the first aspect of the present invention is characterized by comprising the following components ( ⁇ :) to ( ⁇ ) [100 parts by weight in total of (8), ( ⁇ ), (C). (D), CE)].
- the content is a water-dispersible hot melt composition.
- a second aspect of the present invention is directed to a moisture-proof paper characterized in that a moisture-proof layer made of the hot melt composition is provided on at least one surface of a paper base material.
- a third aspect of the present invention includes moisture-proof paper provided with a barrier coat layer on the moisture-proof layer of the second aspect.
- a fourth aspect of the present invention is directed to a moisture-proof paper characterized in that the hot melt composition is interposed between two or more paper substrates.
- a filler layer is provided on the surface of the paper base on which the hot melt composition is provided and on the surface of the paper base or the other paper base in contact with the hot melt composition.
- the content is the provided moisture-proof paper.
- a sixth aspect of the present invention is directed to a method for producing a moisture-proof paper according to the second aspect, characterized in that the hot-melt composition is applied on at least one side of a paper substrate to form a moisture-proof layer. .
- a seventh aspect of the present invention is the third aspect, wherein the hot melt composition is applied on at least one side of a paper base to form a moisture-proof layer, and further, a barrier coat layer is formed on the surface.
- the method for producing a moisture-proof paper according to the invention is described.
- An eighth aspect of the present invention is directed to a method for producing a moisture-proof paper according to the fourth aspect, characterized in that the hot-melt composition is coated on at least one surface inside two or more paper substrates. .
- a ninth aspect of the present invention is that, before applying the hot melt composition to the paper base in the eighth aspect, the coated surface of the hot melt composition of the paper base and / or another facing paper base.
- the method for producing a moisture-proof paper according to the fifth aspect of the present invention includes applying an itching agent to a surface of the material in contact with the hot melt composition.

This Those having a molecular weight (weight average) of about 100 to 1200 are suitable. If the molecular weight is less than 100, the moisture-proof layer may not have sufficient coating strength, and the resin may bleed in the drying step of making the recycled paper. Also
- the amount of the amorphous polyalphaolefin used is 30 to 55 parts by weight, preferably 40 to 55 parts by weight. If the amount is less than 30 parts by weight, the moisture-proof property deteriorates and the price advantage decreases. If the amount exceeds 55 parts by weight, the moisture-proof property and the disintegration property deteriorate.
- hot melt compositions imparting moisture resistance are widely used in the industry for packaging.
- those hot melt compositions are often used as an adhesive for bonding paper and paperboard, and thus have high adhesiveness. For this reason, even if it is applied on a paper substrate with reduced adhesiveness, for example, when it is wound up and stored in a roll state for a long period of time, the so-called sticking of the surfaces of the moisture-proof paper in the roll is so-called. May cause a blocking phenomenon.
- the surface of the moisture-proof layer comes into contact with the opposite surface (the back side of the paper base material) on which the moisture-proof layer is not provided, so that the components of the moisture-proof paper in the moisture-proof layer Moves to the other side and becomes very slippery.
- the tackifier (B) used in the present invention includes rosin, modified rosin, and ester compounds thereof, alkylphenol resin, ⁇ -gin and alkylphenol-modified xylene resin, Be Phenolic resins and aromatic hydrocarbon resins such as terpene resins and olefinic resins; aromatic hydrocarbon resins such as styrene resins; and aromatic petroleum resins. And coumarone-indene resin, isoprene-based resin and the like. Any of these may be selected, and they are used alone or in combination of two or more. Among these, aliphatic hydrocarbon resins, aromatic hydrocarbon resins, terpene resins, and rosin resins are particularly preferred in terms of ease of dissolution.
- the used amount of the deadening agent is 3 to 25 parts by weight. With 3 parts by weight of red drops, the moisture resistance is insufficient, and with more than 25 parts by weight, the moisture barrier will crack when cross-folding, and the moisture resistance will be reduced. Further, from the viewpoint of the above-mentioned slip resistance and blocking resistance, the amount is preferably about 3 to 10 parts by weight.

These may be used alone or in combination of two or more. Particularly, the softening point is preferably 105 or more, and a crystalline polyolefin-based resin is preferable in that it shows good performance in terms of slip resistance.
- the amount of wax used is between 20 and 45 parts by weight. If the amount is less than 20 parts by weight, the moisture resistance becomes insufficient. If the amount exceeds 45 parts by weight, bleeding occurs at the time of papermaking after disintegration, and the slip resistance decreases.
- moisture-proof paper has a problem that it is difficult to adhere with an adhesive at the time of packaging, for example.
- Hot-melt synthetic rubber adhesive type glue does not cause poor adhesion during packaging, but easily pollutes the working environment.
- hot-melt glue ethylene-butyl acetate resin glue may have insufficient adhesive strength with the moisture-proof layer compared to conventional polyethylene moisture-proof paper.
- emulsion / latex pastes inexpensive vinyl acetate resin-based emulsion pastes, which have been used in the past, cannot be used because of the lack of adhesive strength when adhering to moisture-proof paper that can be disassembled. Many. In addition, the vinyl acetate resin emulsion paste is repelled on the moisture-proof surface and may not even be applied well.
- the above-mentioned problem of the adhesiveness can be solved by using an oxidized box and Z or an acid-modified box together with the wax component of the hot melt composition. This will improve the adhesion between the moisture barrier and the paper base, improve the adhesion between the moisture barrier and the packaging glue, and improve the adhesion with the overcoat agent such as barrier coat. As a result, the quality of the moisture-proof paper is stabilized, and inexpensive glue for packaging can be used.
- the oxidized wax or acid-modified wax used in the present invention is a wax obtained by oxidizing the above wax by a chemical reaction and introducing an acid group such as a carboxyl group.
- Polyethylene wax, polypropylene wax, oxide wax obtained by chemically reacting fine wax, and acid-modified wax are preferable, and these are used alone or in combination of two or more.
- the used amount of the oxidized wax and / or the acid-modified wax is 0.1 to 20 parts by weight of the used amount of 20 to 45 parts by weight in that the moisture-proof property is not reduced and the effect of improving the adhesiveness is recognized. It is.
- the (D) polyolefin-based resin used in the present invention those used for injection molding or the like having a molecular weight (number average) of 100 to 5,000 are preferably used. When the molecular weight is less than 100,000 If the heat resistance exceeds 50,000, it becomes difficult to melt and mix the hot melt composition.
- the amount of the polyolefin resin used is 220 parts by weight. If the amount is less than 2 parts by weight, the above-mentioned heat resistance becomes insufficient. If the amount exceeds 20 parts by weight, cracks tend to occur in the moisture-proof layer at the time of cross-folding, and the moisture-proof performance deteriorates.
- a polypropylene resin is preferably used because of its high heat resistance and good compatibility.
- the (E) compatibilizer used in the present invention includes polypropylene grafted with an acid component such as maleic anhydride, a low-crystallization ethylene-propylene copolymer, an ethylene-vinyl acetate copolymer, and an ethylene-methacrylate.

- examples thereof include polyolefin resins such as acrylic acid (ester) copolymer, and those having a molecular weight (number average) in the range of 100 to 5,000 are preferably used. If the molecular weight is less than 1000, the above-mentioned heat resistance becomes insufficient, and if it exceeds 500, the compatibilizing effect is reduced. These are used alone or in combination of two or more.
- the amount of the compatibilizer used is 0 to 15 parts by weight. Although 0 part by weight can be used practically, the effect of improving the moisture resistance may be insufficient, so 1 to 7 parts by weight is preferable. If the amount exceeds 15 parts by weight, the thermal stability of the hot melt composition deteriorates, and the moisture resistance decreases.
- the amount of each component used is 100 parts by weight in total of the components (A) to (E).
- the moisture-proof paper When recyclable moisture-proof paper is recycled into waste paper, the moisture-proof paper is put into a pulp or the like as in other waste paper recycling, and dispersed in a pulp form by mechanical stirring in a water-suspended state. At this time, if the specific gravity of the moisture-proof layer is 1 m, the resin composition separated from the paper substrate floats on the water and associates with the stagnation site of the paper machine to form a lump with other impurities. As a result, there is a possibility that defects may occur in the recycled paper. This problem can be solved by blending an inorganic filler with the hot melt composition of the present invention and setting its specific gravity to 0 or more.
- this improves the mixing property with the pulp in the water suspension state, allows the resin composition floating in water to be significantly reduced, and prevents the quality of recycled paper from deteriorating.
- large amounts of disintegratable moisture-proof paper will be used for the purpose of saving resources and protecting the environment, and it is expected that it will be reused as waste paper.However, it is extremely important to prevent the deterioration of recycled paper quality. is there.
- the inorganic filler compounded to make the specific gravity of the hot melt composition 1.0 or more.
- the specific gravity of the inorganic filler is generally 2.4 or more, and in this case, the amount of the inorganic filler used is about 5 parts by weight or more based on 100 parts by weight of the hot melt composition.
- the upper limit of the specific gravity of the hot melt composition is not particularly limited, but if it is too large, the miscibility with the pulp in the water-suspended state is rather deteriorated. Therefore, it is preferably about 20 parts by weight or less.
- Non-filamentary fillers include spherical ones such as calcium carbonate, needles such as talc and my strength, and plain ones, but all can be used. These are appropriately selected from the kneadability with the hot melt composition.

It is also possible to enhance the effect of preventing a decrease in slip resistance and the effect of preventing blocking. However, since the use of a large amount of paraffins and waxes lowers the slip resistance and printability, it is preferably about 1 to 10 parts by weight based on 100 parts by weight of the resin. A liquid in which these resins are dissolved or dispersed in various solvents is applied to form a Paricoat layer. Coating amount is 0, 1 ⁇ 3.
- O g / m 2 is suitably, 0. 1 g Zm 2 not sufficient effect as a barrier one coating layer is non ⁇ and 3.
- the 0 g / m 2 Exceeding this is not preferred because it not only reduces the disintegration, but also increases the cost.
