Description

Catalloy modified resin composition for coating double wall fabrics, and preparing method of double wall fabrics enhanced air tightness including coating layer using the same}

The present invention relates to a double space paper having improved air tightness by coating a Ketaloy modified resin composition for coating a double space paper fabric fabric on a polyester or polypropylene fabric, and a method of manufacturing the same. Specifically, the Ketaloy-modified resin composition for coating a double-spaced fabric fabric according to the present invention includes a master batch for preventing oxidation and improving light resistance, a master batch for enhancing surface abrasion resistance, and a master batch for coloring. When coated on the surface of double-spaced fabric by adding quantitatively, it improves mechanical properties such as durability and weather resistance of double-spaced paper, and extends the life of double-spaced products due to its excellent airtightness, and is eco-friendly and economical because it can be recycled. , As it can be made ultra-lightweight, it has improved the completeness of the double-space product.

The double space paper is a tricot of a knitted structure with a fineness of 400 denier to 500 denier yarn woven with a double rassell loom and a warp density of 15 to 30 (all/inch) and a weft density of 15 to 30 (all/inch) When air is injected into a fiber fabric made of spacer yarns connected at regular intervals of 20 to 25 (all/20cm) in the warp direction and 15 to 20 (all/20cm) in the weft direction, the upper and lower ends of the fabric are connected to the upper and lower ends of the fabric. As a product with the principle that the space yarn, which is swelled up to the length of the space yarn and connected to the upper and lower ends of the fabric, acts as a pillar, products using this include various products such as air mattresses, air sofas, air tubes for playing in the water, surf boats, and kayaks.

In recent years, the European Union, the United States, and the Commonwealth have been strengthening regulations on the use of polyvinyl chloride (PVC), and accordingly, countries around the world have attempted to develop various resins that replace polyvinyl chloride. A resin comparable to polyvinyl chloride in terms of processability and economic feasibility has not been developed.

Double space paper is generally manufactured by coating polyester double space fiber with polyvinyl chloride resin or Thermoplastic Polyurethane (TPU) resin, but double space paper manufactured by coating polyvinyl chloride resin on polyester double space fiber When discarded after use, it is difficult to separate the coating material, polyvinyl chloride resin and polyester double space, and the recycling cost is high.Therefore, there is a serious problem of generating dioxins and toxic gases during incineration, and it is included in the coating resin processing formulation. There are high concerns about phthalate plasticizers, which are substances that regulate environmental hormones.

In addition, the double space paper produced by coating the polyester double space fiber with TPU resin cannot be applied to the calendar method or the sol coating method used for polyvinyl chloride in terms of processability, and is not applicable to the extrusion T-Dies method. It can only be produced by means of limited production facilities, and the cost of TPU resin as a coating material is expensive, so economical efficiency is low.When disposing of it after use, it is difficult to separate the TPU resin as a coating material from the polyester double space, so the recycling cost is high and incineration Although it is being disposed of, there is a serious problem of generating hydrogen cyanide and toxic gases during waste incineration. In addition, the double space paper produced by coating a polyester double space fiber with a polyvinyl chloride resin or a TPU resin has the inconvenience of having to undergo a lamination process using an adhesive.

Accordingly, the inventors of the present invention have continuously studied a composition for coating a double space paper that can replace polyvinyl chloride.

Korean Patent No. 1471997 is a technology of the present inventor, based on 100 parts by weight of olefin block copolymer, 50 to 100 parts by weight of polypropylene, 0.1 to 50 parts by weight of polypropylene modified elastomer, polystyrene modified elastomer or polyolefin rubber Polypropylene modified compound containing 0.1 to 50 parts by weight, inorganic filler 0.1 to 20 parts by weight, antioxidant 0.1 to 1.0 parts by weight, UV absorber 0.1 to 2.0 parts by weight, processing lubricant 0.1 to 3.0 parts by weight, colorant 1 to 15 parts by weight A technique was devised to improve the mechanical properties of the double space paper by coating the surface of the double space paper using the composition.

However, the inventors of the present inventors, in the step of actually mass-producing and practically using double space paper, in the case of a polypropylene modified compound resin composition, a resin having a low softening point and a melting point of 130°C or less was used, so the heat resistance was insufficient and exposed to the outdoors for a long time. It has been found that it is difficult to use for air structures such as surf boats used in tropical seashores, metres used in desert areas, and air tent structures.

In addition, the air-tightness of the double space paper itself is excellent, but the adhesion of the adhesive part with the wall fabric, which is essential when manufacturing various air structures using the double space paper, is weakened, so that the double space paper and the wall paper are separated. It has been found that a phenomenon occurs and the pressure of the air filled inside the double space is easily dropped, which leads to a decisive disadvantage, especially in the safety of air structures used in the water.

Under this background, the inventors of the present invention use a Catalloy modified resin including a master batch for antioxidant and light resistance improvement, a master batch for enhancing surface abrasion resistance, and a master batch for coloring in a Catalloy resin. In the case of using it as a coating composition for fabric, it has been found that it has an excellent air tightness effect as well as improvement of mechanical properties such as heat resistance strength, and can improve the completeness of a double-spaced product to complete the present invention. Reached.

It is an object of the present invention to provide a Ketaloy modified resin composition for coating a double-spaced fabric fabric.

In addition, another object of the present invention is to provide a method of manufacturing a double space paper with improved air tightness.

In order to achieve the above object, the present invention is primarily based on three types of monomers consisting of (A) ethylene monomer, propylene monomer, and 1-butene monomer. G/N) reacting with a catalyst to prepare a gaseous prepolymer as an intermediate and then secondaryly polymerize 100 parts by weight of the Catalloy resin, (B) Antioxidation and light resistance improvement 3 to 5 parts by weight of the master batch; (C) 5 to 10 parts by weight of a master batch for enhancing surface abrasion resistance; And (D) it provides a ketaloy modified resin composition for coating a double-spaced fabric fabric containing 5 to 15 parts by weight of the master batch for coloring.

In addition, it provides a method for producing a double space paper with improved air tightness, comprising coating the ketaloy resin composition for coating the double space fabric fabric on both sides of a polypropylene double space paper fabric.

First, the present invention exhibits an excellent processability effect as the ketaloy resin composition for coating a double-spaced fabric fabric can be coated on a double-spaced paper by applying the extrusion T-Dies method.

Second, the present invention does not require a separate compounding of the modified resin composition for coating the double space paper used in the manufacture of the double space paper.

Third, the present invention does not generate toxic gases such as dioxin and hydrogen cyanide during incineration, and volatile organic compounds (VOCs, Volatile Organic compounds) do not occur in the manufacturing process because the adhesive method does not use an organic solvent-type liquid adhesive. It is not related to air pollution. Particularly, the double space area using a fabric woven with polypropylene filament yarn as the core is 100% recyclable because the fabric and the coating material are the same material, and it is non-toxic and eco-friendly because it does not use phthalate plasticizer, which is an environmental hormone regulatory substance harmful to the human body. Shows the effect.

Fourth, since the present invention does not use a phthalate-based plasticizer, which is an environmental hormone-regulating substance, the effect of preventing contamination due to pigment migration is very excellent when manufacturing a structure using a double space where human body contact occurs due to the plasticizer.

Fifth, the present invention has the effect of showing physical properties enough to replace the conventional double space paper coated with polyvinyl chloride on a polyester fabric, and it is very light due to the nature of the material, and excellent air tightness, which is very important for air structures. It works.

Figure 2 is a schematic diagram of the synthesis of ketaloy resin according to the present invention.
Figure 3 is a schematic diagram of a double space according to the present invention.

Hereinafter, preferred embodiments of the present invention and the physical properties of each component will be described in detail, but this is for explaining in detail enough that a person having ordinary knowledge in the technical field of the present invention can easily carry out the invention. It does not mean that the technical spirit and scope of the present invention are limited.

The inventors of the present invention use a Catalloy modified resin including a masterbatch for preventing oxidation and improving light resistance, a masterbatch for enhancing surface abrasion resistance, and a masterbatch for coloring in a Catalloy resin to The present invention was completed by knowing that it has an excellent air tightness effect as well as improvement of mechanical properties such as heat resistance when manufacturing a double space paper and uses it to improve the completeness of a double space paper product. It came to the following.

Accordingly, in the present invention, three kinds of monomers consisting of (A) ethylene monomer, propylene monomer, and 1-butene monomer are primarily used as a Ziegler-Natta (G/N) catalyst. (B) 3 to 5 master batches for preventing oxidation and improving light resistance based on 100 parts by weight of the Catalloy resin obtained by secondary polymerization after preparing a gaseous prepolymer as an intermediate by reacting with Parts by weight; (C) 5 to 10 parts by weight of a master batch for enhancing surface abrasion resistance; And (D) it provides a ketaloy modified resin composition for coating a double-spaced fabric fabric comprising 5 to 15 parts by weight of a coloring master batch.

The catalloy resin (A) according to the present invention is primarily composed of three types of monomers consisting of ethylene monomer, propylene monomer, and 1-butene monomer. A controlled porosity reaction using a catalyst (Ziegler's catalyst) is carried out to prepolymer in a gaseous state, followed by polymerization in three stages, followed by polymerization and drying with steam. It means resin (Fig. 2).

The Catalloy resin usually uses 5 to 10% by weight of ethylene monomer, 10 to 20% by weight of propylene monomer, and 70 to 80% by weight of 1-butene monomer. However, it is a resin with a high 1-butene monomer content, but the molecular structure is very homogeneous, so the surface appearance is excellent when processing an extruded film or an extruded sheet. Do.

Ethylene monomer (etylene monomer) 5 to 10% by weight, propylene monomer (propylene monomer) of 10 to 20% by weight allows compatibility with other polyolefin resins (polyethylene or polypropylene), especially propylene monomer (propylene monomer) from 10 to 20% by weight. 20% by weight guarantees the heat resistance of Catalloy resin. 1-butene monomer (70 to 80% by weight) gives the Catalloy resin a rubber-like property, showing excellent cold resistance, high flexural strength, and soft flexibility, even though it is a resin of low density and low hardness. It allows high heat resistance to be expressed.

The Catalloy resin according to the present invention must have a melt flow ratio (MFR) (210°C/2.16kg, ASTM D1238) of 0.5 g/10min to 5.0 g/10min, and have a melt elasticity (MEF; Melt Flow Ratio) of 0.5 g/10min to 5.0 g/10min. Elasty Force (ASTM D790) is 20 Mpa to 80 Mpa, hardness is Shore A, 70A to Shore D, 40D, melting point (ASTM D3418) is 140°C to 160°C, 1-butene content is 70 It is preferably at least %.

到)가 맞지 않는 불량의 원인이 되며, 용융탄성강도가 20 메가파스칼(Mpa) 미만이면 내열 인장강도가 너무 낮고 80 메가파스칼(Mpa) 이상이면 이중공간지를 이용하여 만들어지는 공기부양 구조물이 뻣뻣해지는 불량요인이 된다. 경도가 70A 미만은 수지가 너무 부드러워 표면 스크러치가 심해지며 40D 초과하면 저온 굴곡성이 현저히 감소하여 표면 크랙이 발생할 수 있어 수명 내구성에 영향을 준다. 융점은 140℃ 이상이면 매우 좋은데 이는 이중공간지가 사용되는 기후 환경적 요인, 즉 열대 바다 모래사장 또는 사막에서도 견디어야 하기 때문이며 코팅 가공 시 높은 온도가 요구되는 170℃를 초과할 필요는 없다. 또한 1-부텐 함량이 70% 이상인 것이 바람직한 이유는 1-부텐 함량이 70% 이상이면 러버라이크(Rubber Like)하여 이중공간지의 유연성, 높은 굽힘강도, 우수한 저온 특성과 높은 내열특성을 동시에 부여해 준다. At this time, if the melt index exceeds 5.0 g/10min, the penetration of the resin through the fabric yarns increases during coating, and the space yarn of the double space paper is attached to the fabric wall, and the meandering degree of the double space paper mentioned above (絲)

If 到) does not fit, the heat-resistant tensile strength is too low if the melt elastic strength is less than 20 megapascals (Mpa), and if it is more than 80 megapascals (Mpa), the air-lifting structure made using the double space paper becomes stiff. It becomes a bad factor. If the hardness is less than 70A, the resin is too soft and the surface scratch becomes severe. If it exceeds 40D, the low-temperature bendability decreases significantly, resulting in surface cracking, which affects the durability of the service life. A melting point of 140°C or higher is very good, because the double space has to withstand the climatic and environmental factors used, ie tropical sea sandy beaches or deserts, and there is no need to exceed 170°C, which requires a high temperature during coating processing. In addition, the reason why it is preferable that the 1-butene content is 70% or more is that when the 1-butene content is 70% or more, it is rubber-like, giving the double space flexibility, high bending strength, excellent low-temperature characteristics, and high heat resistance characteristics at the same time.

Since the Catalloy resin uses a Ziegler catalyst (G/N catalyst), extrusion or injection processing is easy, and it has excellent physical properties at low and high temperatures, and has flexibility, softness, and high temperature. A suitable balance is achieved in terms of high temperature resistance, scratch resistance, chemical resistance, and tensile strength. The product uniformity that cannot be matched with other plastomer or elastomer compounds, the dispersibility of 1-butene with rubber properties, and the compatibility between 1-butene and the matrix are excellent. It realizes a beautiful surface that cannot be compared with a compound having the same stiffness and flexibility, and the content of 1-butene is relatively large. Nevertheless, it is well-dispersed, so there is almost no non-dispersed material such as gel, which has a good effect on the air tightness of the double space used for air flotation. In addition, it is easy to mix with other polyolefins when compounding.

The antioxidant and light resistance improvement master batch (Master Batch, M/B) (B) contains 1 to 10% by weight of an antioxidant; 5 to 20% by weight of an ultraviolet absorber; And the mixture containing the remaining amount of Catalloy resin is cold blended with a first Henschel mixer or a super mixer, and then melted and extruded with an extruder to water-cool the resin-like noodles with a diameter of 2 mm to 4 mm. Next, it may be a master batch prepared by pelletizing and drying so that the length is about 2 mm. At this time, the diameter or length of the mast batch should be similar to the size of the Ketaloy resin, but this does not play a decisive role in the quality of the product.

As an example, the melt extrusion conditions may use a two win screw extruder as an extruder, and the cylinder temperature may be 190°C to 220°C, the adapter temperature 220°C, and the die temperature may be 220°C. It is not necessarily limited thereto.

In more detail, the antioxidant is 1,1,1-tris(2-methyl-4-hydroxy-5-tertiary-butylphenyl)butane, 1,3,5-trimethyl-2,4,6-tris( 3,5-di-tertiary-butyl-4-hydroxybenzyl)benzene, tetrakis-[methylene-3-(3'5'-di-tertiary-butyl-4-hydroxyphenyl)propinate], Bis[3,3'-bis-(4'-hydroxy-3'-tertiary-butylphenyl)butylic acid] glycol ester, 1,3,5-tris(3',5'-di-tertiary -Butyl-4'hydroxybenzyl)-SEC-triazine-2,4,6-trione, 3,5-di-tertiary-butyl-4-hydroxyhydrocinnamate octadecyl, tris(2,4 -Di-tertiary-butylphenyl) phosphate, cycloneopentantetrayl bis (2,4-di-tertiary-butylphenyl) phosphate and 1,2-bis (3,5-di-tertiary-butyl-4 It may be any one selected from the group consisting of -hydroxyhydrocinnamoyl)hydrazine.

In addition, the ultraviolet absorber is benzophenone-based, phenyl silicate, bis(2,2,6,6-tetramethyl-4-piperidinyl) sebacate, 2-(3'-5'-di-tertiary-butyl- 2'-hydroxyphenyl)-5-chlorobenzotriazole, 2-(3,5-di-tertiary-phenyl-2-hydroxyphenyl)benzotriazole, 2-(2'-hydroxy-5- Any one selected from the group consisting of methylphenyl)benzotriazole, 2-(3'-tertiary-butyl-2'-hydroxy-5'-methylphenyl)-5-chlorobenzotriazole and hinderedamine-based UV stabilizers I can.

The master batch for preventing oxidation and improving light resistance improves weather resistance and light resistance by blocking changes in physical properties from ultraviolet rays and preventing discoloration and aging.

It is preferable to use 3 to 5 parts by weight of the master batch for preventing oxidation and improving light resistance, based on 100 parts by weight of the Catalloy resin. Even if the master batch for antioxidant and light resistance improvement is used in excess of 5 parts by weight, the effect does not increase, so there is no need to use more than 5 parts by weight.

The surface abrasion resistance enhancement master batch (C) is a polyurethane bead or acrylic bead in the form of fine spherical particles 10 to 30% by weight; And a mixture containing 70 to 90% by weight of a polypropylene resin is cold blended with a first Henschel mixer or a super mixer, and then melted and extruded with an extruder to water-cool a resin shaped like noodles with a diameter of 2 mm to 4 mm. Next, it may be a master batch prepared by pelletizing and drying so that the length is about 2 mm. At this time, the diameter or length of the mast batch should be similar to the size of the Ketaloy resin, but this does not play a decisive role in the quality of the product.

As an example, the melt extrusion conditions may use a two win screw extruder as an extruder, and the cylinder temperature may be 190°C to 220°C, the adapter temperature 220°C, and the die temperature may be 220°C. It is not necessarily limited thereto.

This increases the durability of the double space paper because it increases the scratch and abrasion properties of the Ketaloy modified resin coated on the fabric surface used as the core of the double space paper.

The master batch for enhancing surface abrasion resistance is preferably 5 to 10 parts by weight based on 100 parts by weight of the Catalloy resin. If less than 5 parts by weight is used on the basis of the mast badge, the effect decreases, and if it exceeds 10 parts by weight, the effect increases, but the cost-effectiveness ratio of the increase of the effect to the amount of use decreases and only increases the cost.

In addition, it is preferable to use the polyurethane beads or acrylic beads having a spherical shape having an average particle diameter of 5 to 10 microns.

If the average location is less than 5 microns, even dispersion is difficult during the manufacture of the master badge, and if the average location is larger than 10 microns, the surface area relative to the weight of the beads added becomes smaller and the abrasion resistance effect is inferior.

The coloring master batch paper (D) is a pigment 15 to 60% by weight; 37 to 82% by weight of polypropylene resin; 1 to 2% by weight of a pigment dispersant; And a mixture containing 0.5 to 1% by weight of zinc stearate is cold blended with a first Henschel mixer or a super mixer, and then melt-extruded with an extruder to have a diameter of 2 mm to 4 mm. It may be a master batch prepared by water cooling and then pelletizing to have a length of about 2 mm and drying. At this time, the diameter or length of the mast batch should be similar to the size of the Ketaloy resin, but this does not play a decisive role in the quality of the product.

As an example, the melt extrusion conditions may use a two win screw extruder as an extruder, and the cylinder temperature may be 190°C to 220°C, the adapter temperature 220°C, and the die temperature may be 220°C. It is not necessarily limited thereto.

The amount of pigment used can be adjusted according to the type of color, and the pigment should be used with a light fastness grade and heat resistance grade 4 or higher. This is because the temperature at which the Ketaloy modified resin is extruded and coated on the fabric when manufacturing double space paper is at a high temperature of 250℃ or higher, and most of it is used outdoors when making and using an air-lifting structure with double space paper, so it should not be discolored by sunlight. Therefore, it is preferable to use a grade 4 or higher.

The amount of the coloring master batch is adjusted according to the type of color, but it is preferable to use 5 to 15 parts by weight based on 100 parts by weight of the Catalloy resin. This is because 5 parts by weight of dark color and 15 parts by weight of light color are used because of the hiding power of the double-spaced fabric.

In addition, the present invention air-tightness comprising the step of coating a Ketaloy modified resin composition for coating a double-spaced fabric fabric containing the above (A) to (D) on both sides of a double-spaced fabric made of polypropylene or polyester This improved method for manufacturing a double space paper is provided.

The woven fabric for double space paper woven from polyester multifilament yarn or polypropylene multifilament yarn according to the present invention has a single yarn strength of 6.8 gf/d to 8.0 gf/d, which is a high-strength, low-shrink non-twisted yarn 400 Tricot of a knitted structure woven with a double Rut cell loom with a weaving density of 15 to 30 warp per inch and 15 to 30 weft yarns using polyester multifilament yarn or polypropylene multifilament yarn of denier to 500 denier There may be a space yarn of 25 mm to 400 mm between the double fabric.

The tricot according to the present invention is a type of fabric made with a difference in the manufacturing method according to the production direction when fabricating. In the present invention, the double space is swollen when air is injected into the space yarns connected to the upper and lower ends of the fabric at regular intervals. It has the principle of holding and supporting the upper and lower ends of the fabric as much as the length of the space yarn as it rises, and it may be an air mat as a representative.

The double space fabric fabric As a coating method for the coating Ketaloy modified resin composition, the extrusion T-Dies method is the most preferable method because it does not require an adhesive. Extrusion T-Dies method, as shown in Figure 1, the pellet-type ketaloy resin and the (B) to (C) masterbatch firstly cold branded (Cold Blending), and then the extruder hopper Into the extruder through the extruder, the cylinder temperature of the extruder is 220°C to 250°C, the adapter temperature is 250°C to 260°C, and the die temperature is 250°C to 260°C by T-dies with a thickness of 0.4 mm to 0.6 mm. It is produced by extrusion lamination with polyester double space fabric or polypropylene double space fabric while discharging with.

As for the polishing roll for lamination, the first silicone roll is a cooling roll, and the second steel roll is maintained in the range of 30°C to 50°C, and the third steel roll is in the form of a cooling roll. At this time, rolls 1 and 3 must use a chiller that has passed through a freezer. Steel Roll No. 2 plays a role of polishing the coated surface and plays the role of smoothness, glossiness, and surface embossing of the coated surface. Lamination compression is preferably 5.0 Kgf/cm 2 or more.

If the single yarn strength of the polyester multifilament or polypropylene filament used when weaving the double-spaced fabric fabric is less than 6.8 gf/d, the tensile strength and tear strength of the double-spaced paper to be implemented in the present invention are lowered, resulting in lower product value. If it exceeds 8.0 gf/d, it is not yet mass-produced worldwide, and the price rises exponentially and economic feasibility decreases.

Polyester multi-filament yarn or polypropylene multi-filament yarn used when weaving the double-spaced fabric fabric must be a non-twisted yarn, which partially melt penetrates the Ketaloy modified resin composition for coating according to the present invention between the double-spaced fabrics. The interlayer adhesion between the double-spaced fabric and the coating Ketaloy modified resin composition is excellent, but in the case of flexible yarn, excellent adhesion cannot be obtained because the melt penetration of the coating Ketaloy modified resin composition is not good.

Polyester multifilament yarn or polypropylene multifilament yarn used when weaving the double-spaced woven fabric should have a fineness of 400 to 500 denier. In this case, when the fineness is less than 400 denier, the fineness is low and the tensile strength and phosphorus of the double-spaced paper It should be avoided because the thermal strength is lowered. If it exceeds 500 denier, not only it is difficult to weaving, but also the surface smoothness of the double-spaced fabric decreases, and the folding flexibility of the double-spaced fabric decreases because the fabric is too thick, and acts as a negative factor in weight reduction, which is the advantage of the present invention, and the fabric price increases. There are obstacles to economic feasibility.

到)가 맞지 않는 불량의 원인이 되며, 1 인치 당 30을 초과하면 이중공간지에서 요구되는 물성 이상이므로 중량만 올라가고 생산 원가만 상승시키므로 본 발명에서 구현하고자 하는 이중공간지용 직물의 제직 밀도는 경사 1 인치 당 15 내지 30, 위사 1 인치 당 15 내지 30의 제직 밀도를 지닌 니트 조직의 트리코트 직물이 가장 바람직하며 이중공간지의 기둥 역할을 하는 공간사는 경사 방향으로 20 내지 25(올/20cm), 위사 방향으로 15 내지 20(올/20cm)의 일정 간격으로 연결된 것이 바람직하다.When weaving the double space paper fabric, the weaving density is a tricot fabric of a knitted structure having a weaving density of 15 to 30 per inch of warp and 15 to 30 per inch of weft, which has a weaving density of 1 If it is less than 15 per inch, physical properties such as tensile strength and tear strength of the double space paper are lowered, and the coated Ketaloy modified resin composition excessively penetrates the double space paper fabric, and the space yarn adheres to the fabric wall surface, causing the meandering of the double space paper. Do

到) is the cause of mismatch, and if it exceeds 30 per inch, it is more than the properties required for the double space, so only the weight increases and only the production cost increases, so the weaving density of the double space fabric to be implemented in the present invention is inclined. The tricot fabric of a knitted structure having a woven density of 15 to 30 per 1 inch and 15 to 30 per inch of weft is most preferable, and the space yarn serving as a pillar of the double space is 20 to 25 (all/20 cm) in the warp direction, It is preferable that they are connected at regular intervals of 15 to 20 (all/20 cm) in the weft direction.

The inventors of the present invention use a ketaloy modified resin containing a predetermined amount of a master batch for preventing oxidation and improving light resistance, a master batch for enhancing surface abrasion resistance, and a master batch for coloring in a ketaloy resin as a composition for coating a double-spaced fabric fabric. By doing so, it is possible to improve the mechanical properties such as heat resistance, as well as to manufacture a double space that has an excellent air tightness effect, thereby enhancing the completeness of the product and improving the safety of air structures used in the water. In addition, since the double space paper is recyclable, it is eco-friendly, is ultra-lightweight, non-toxic, and can be easily manufactured through a T-Dies extrusion process even in the manufacturing method, so it has excellent processability and economy.

Hereinafter, examples will be described in detail to aid understanding of the present invention. However, the following examples are merely illustrative of the contents of the present invention, and the scope of the present invention is not limited to the following examples.
