在本發明被詳細描述前，應當注意在以下的說明內容中，類似的元件是以相同的編號來表示。Before the present invention is described in detail, it should be noted that in the following description, similar elements are represented by the same numbers.

本發明的塑木結構可用於戶外或室內之裝潢建材，例如，可用於室內的仿木地磚、仿木裝飾貼片或是戶外的造景、欄杆、階梯等並無特別限制。The wood-plastic structure of the present invention can be used for outdoor or indoor decoration and building materials. For example, wood-like floor tiles, wood-like decorative patches that can be used indoors, or outdoor landscaping, railings, stairs, etc. are not particularly limited.

參閱圖1，本發明塑木結構的一實施例包含一芯體2、一皮層3。Referring to FIG. 1, an embodiment of a plastic-wood structure according to the present invention includes a core body 2 and a skin layer 3.

該芯體2是由一塑木組成為材料所構成，該塑木組成包含布料、相容劑，及改質劑。且以該塑木組成的重量百分比為100wt%計，該布料的含量為30-60wt%，且該相容劑的含量為10-25wt%。且其中，該塑木組成不含木粉。The core body 2 is composed of a plastic-wood composition. The plastic-wood composition includes cloth, a compatibilizer, and a modifier. And based on the weight percentage of the plastic-wood composition being 100 wt%, the content of the cloth is 30-60 wt%, and the content of the compatibilizer is 10-25 wt%. Moreover, the plastic-wood composition does not contain wood flour.

其中，該布料包含聚酯或棉的其中至少一種。於一些實施例中，該布料是來自廢棄回收布料，包含聚酯及棉，且聚酯與棉的重量百分比介於10：90~90:10。The cloth includes at least one of polyester or cotton. In some embodiments, the cloth is from waste recycled cloth, including polyester and cotton, and the weight percentage of polyester and cotton is between 10:90 and 90:10.

於一些實施例中，該布料中聚酯與棉的重量比約為1:1。In some embodiments, the weight ratio of polyester to cotton in the cloth is about 1: 1.

該相容劑選自疏水性高分子改質的澱粉或親水性改質的聚烯烴。The compatibilizer is selected from hydrophobic polymer modified starch or hydrophilic modified polyolefin.

於一些實施例中，該疏水性高分子改質的澱粉選自聚乙烯接枝改質的澱粉或聚丙烯/乙烯醋酸乙烯酯共聚物(PP/ EVA)接枝改質的澱粉。該親水性改質的聚烯烴可為馬來酸酐(Maleic anhydride，MA)接枝改質聚烯烴(MA-POE)，例如：馬來酸酐接枝改質聚乙烯(MA-PE)、馬來酸酐接枝改質聚丙烯(MA-PP)；或是乙烯醋酸乙烯酯共聚物(EVA)改質的聚烯烴(EVA-POE)。In some embodiments, the hydrophobic polymer-modified starch is selected from polyethylene grafted modified starch or polypropylene / ethylene vinyl acetate copolymer (PP / EVA) grafted modified starch. The hydrophilic modified polyolefin may be maleic anhydride (MA) graft modified polyolefin (MA-POE), for example: maleic anhydride graft modified polyethylene (MA-PE), male Anhydride graft modified polypropylene (MA-PP); or ethylene vinyl acetate copolymer (EVA) modified polyolefin (EVA-POE).

該疏水性高分子改質的澱粉或是親水性改質的聚烯烴的目的均是讓改質後的澱粉或是聚烯烴可同時具有親水性及疏水性基團，因此，可藉由改質後的澱粉或是聚烯烴增加布料中之親水性物質(例如棉)與疏水性高分子材料(例如聚酯)之間的相容性。以澱粉改質為例說明，是利用將澱粉的部分羥基(-OH)進行疏水性改質，讓改質後的澱粉可同時具有親水性及疏水性基團，而可利用改質後的澱粉作為相容劑，增加布料中之親水性物質(例如棉)與疏水性高分子材料(例如聚酯)的相容性。於一些實施例中，該澱粉的疏水性高分子改質率約為20%~25%。The purpose of the hydrophobic polymer modified starch or hydrophilic modified polyolefin is to allow the modified starch or polyolefin to have both hydrophilic and hydrophobic groups. Therefore, the modified starch or polyolefin can be modified. The later starch or polyolefin increases the compatibility between hydrophilic materials (such as cotton) and hydrophobic polymer materials (such as polyester) in the cloth. Taking starch modification as an example, it is described that hydrophobic modification of part of the hydroxyl group (-OH) of starch is used, so that the modified starch can have both hydrophilic and hydrophobic groups, and the modified starch can be used. As a compatibilizer, it increases the compatibility of hydrophilic materials (such as cotton) and hydrophobic polymer materials (such as polyester) in the cloth. In some embodiments, the modified rate of the hydrophobic polymer of the starch is about 20% to 25%.

該改質劑選自親水性改質的聚烯烴或一含有親水性改質聚酯的高分子摻混物，其中，該親水性改質的聚烯烴或該親水性改質聚酯的熔點均會低於布料中的聚酯，藉以降低整體的熔點以提升該塑木組成的加工性，並可進一步增加與該相容劑的相容性。此外，該高分子摻混物還可進一步包含聚乙烯及聚丙烯。The modifier is selected from a hydrophilic modified polyolefin or a polymer blend containing a hydrophilic modified polyester, wherein the melting points of the hydrophilic modified polyolefin or the hydrophilic modified polyester are both Will be lower than the polyester in the cloth, thereby reducing the overall melting point to improve the processability of the plastic wood composition, and can further increase the compatibility with the compatibilizer. In addition, the polymer blend may further include polyethylene and polypropylene.

該親水性改質的聚烯烴如同前述該相容劑所述。該親水性改質聚酯可藉由增加多元醇的含量，除了可增加親水性之外，還可降低該親水性改質聚酯的熔點。The hydrophilic modified polyolefin is as described in the aforementioned compatibilizer. By increasing the content of the polyol, the hydrophilic modified polyester can increase the hydrophilicity and reduce the melting point of the hydrophilic modified polyester.

於一些實施例中，該相容劑選自聚乙烯接枝改質的澱粉，該改質劑選自包含親水性改質聚酯、聚乙烯，及聚丙烯的高分子摻混物。In some embodiments, the compatibilizing agent is selected from the group consisting of polyethylene graft modified starch, and the modifying agent is selected from a polymer blend comprising hydrophilic modified polyester, polyethylene, and polypropylene.

於一些實施例中，該改質劑與該相容劑選用相同的親水性改質的聚烯烴。例如，該相容劑及該改質劑均選自親水性改質的聚烯烴，且該親水性改質的聚烯烴可選自乙烯醋酸乙烯酯共聚物改質的聚烯烴(EVA-POE)。In some embodiments, the modifier and the compatibilizer are selected from the same hydrophilic modified polyolefin. For example, the compatibilizer and the modifier are both selected from hydrophilic modified polyolefins, and the hydrophilic modified polyolefins may be selected from ethylene vinyl acetate copolymer modified polyolefins (EVA-POE) .

該皮層3包覆該芯體2，且該皮層3的構成材料包含親水性改質的聚烯烴或一含有親水性改質聚酯的高分子摻混物。The skin layer 3 covers the core body 2, and a constituent material of the skin layer 3 includes a hydrophilic modified polyolefin or a polymer blend containing a hydrophilic modified polyester.

該親水性改質的聚烯烴或親水性改質聚酯是選自與該芯體的組成的親水性改質的聚烯烴或親水性改質聚酯相同，藉以增加該皮層3與該芯體2的相容性，而增加彼此的密合性。The hydrophilic modified polyolefin or hydrophilic modified polyester is selected from the same hydrophilic modified polyolefin or hydrophilic modified polyester with the composition of the core, so as to increase the skin layer 3 and the core. 2 compatibility, and increase adhesion to each other.

於一些實施例中，該高分子摻混物還可包含聚烯烴，例如聚乙烯(PE)或聚丙烯(PP)等。In some embodiments, the polymer blend may further include a polyolefin such as polyethylene (PE) or polypropylene (PP).

於一些實施例中，該皮層3的構成材料還可包含一添加劑，該添加劑可選自色料、紫外光吸收劑、抗氧化劑、及滑劑的其中至少一種，而讓該皮層3可顯現出不同顏色，或具有其它不同功能(如抗UV或抗氧化等功能)。In some embodiments, the constituent material of the skin layer 3 may further include an additive, and the additive may be selected from at least one of a colorant, an ultraviolet light absorber, an antioxidant, and a slip agent, so that the skin layer 3 can be displayed. Different colors, or have other different functions (such as anti-UV or antioxidant functions).

參閱圖2，於一些實施例中，該皮層3表面也可進一步再形成一層圖案層4、或一層保護層5，或是先於該皮層3面向使用環境的表面先形成一層圖案層4後，再於該圖案層4及其餘的該皮層3表面形成該保護層5，藉此，可令該塑木結構表面呈現不同的花紋圖案，及更佳的保護性。該圖案層4則可以印刷方式形成於該皮層3的表面，該保護層5選自透明清漆，且可以塗佈方式形成，由於該圖案層4及該保護層5的相關材料及製程方法為本技術領預習知，故不再多加贅述。圖2是以該皮層3上還形成有該圖案層4及保護層5為例說明。Referring to FIG. 2, in some embodiments, a pattern layer 4 or a protective layer 5 may be further formed on the surface of the skin layer 3, or a pattern layer 4 may be formed before the surface of the skin layer 3 facing the use environment. Then, the protective layer 5 is formed on the pattern layer 4 and the rest of the skin layer 3, so that the surface of the plastic-wood structure can display different patterns and better protection. The pattern layer 4 can be formed on the surface of the skin layer 3 by printing. The protective layer 5 is selected from transparent varnish and can be formed by coating. Since the relevant materials and process methods of the pattern layer 4 and the protective layer 5 are Technical know-how, so I won't go into details. FIG. 2 illustrates that the pattern layer 4 and the protective layer 5 are further formed on the skin layer 3 as an example.

本發明利用布料作為塑木組成的原料之一，由於現今消費習慣大眾對於衣物、織品的汰換率極高，因而產生大宗的廢棄或回收衣物，然而，這些衣物大部分為聚酯纖維不易分解，使得廢棄衣物的廢棄處理逐漸變成環保的重要議題。因此，本案的塑木組成結合使用廢棄衣物的布料作為原料，由於衣物的主要成份即為石化原料，因此，不僅可減少石化原料的使用還可再利用廢棄衣物，而可對環境更友善。The present invention utilizes cloth as one of the raw materials of plastic wood composition. Due to the current high consumption rate of clothes and fabrics among consumers in the current habit, a large amount of waste or recycled clothes is produced. However, most of these clothes are polyester fibers and are not easy to decompose. , Making the disposal of waste clothing gradually become an important issue of environmental protection. Therefore, the plastic-wood composition of the present case uses the cloth of the waste clothing as the raw material. Since the main component of the clothing is the petrochemical raw material, it can not only reduce the use of the petrochemical raw material, but also reuse the waste clothing, which can be more environmentally friendly.

接著說明前述該塑木結構實施例的製作方法。Next, the manufacturing method of the foregoing plastic-wood structure embodiment will be described.

該塑木結構的製作方法包含一混合步驟，及一加工步驟。The method for manufacturing a plastic-wood structure includes a mixing step and a processing step.

該混合步驟是先將一粉碎後的布料與相容劑混合，並升溫至該相容劑的熔點，使該相容劑包覆該粉碎後的布料形成一加工料。In the mixing step, a pulverized cloth is mixed with a compatibilizing agent, and the temperature is raised to the melting point of the compatibilizing agent, so that the comminuted cloth is covered by the compatibilizing agent to form a processed material.

該加工步驟是將該加工料與該改質劑進行混練得到一芯體材料，將該芯體材料壓出後得到如圖2所示的該芯體2。The processing step is to knead the processing material and the modifier to obtain a core material, and then press out the core material to obtain the core body 2 as shown in FIG. 2.

詳細的說，因為棉無法直接進入混煉機中直接與高分子混煉，因此，本發明藉由先將粉碎後的布料與具有預定結構特性的相容劑先進行預加工，讓布料先與該相容劑融混，令相容劑包覆布料中的棉，形成一可進入混煉機台加工的混合物後，再將該混合物與其它的高分子材料進行混煉後壓出，而可得到該芯體2。藉由相容劑的作用可減少棉與聚酯之間因為異質材料不相容造成的界面分離問題，因此可讓該芯體2間的棉可被高分子材料包覆，不會有相分離的問題。此外，因為棉的含水量較高，因此，在棉與高分子混練的過程中棉所含的水氣會被包覆於高分子混煉物內，而容易造成後續製品的品質及耐用性不佳的缺點。而本發明則是進一步利用在棉與相容劑預混的過程中產生的熱讓棉的水氣逸出並抽氣移除，因此，還可有效減少預混後形成之該加工料的含水率，而提升製品的耐用性及物性。In detail, because cotton cannot be directly entered into the kneader to be directly mixed with the polymer, the present invention first pre-processes the pulverized cloth and a compatibilizer having predetermined structural characteristics to allow the cloth to The compatibility agent is blended, so that the compatibility agent coats the cotton in the cloth to form a mixture that can be processed in the kneading machine, and then the mixture is mixed with other high-molecular materials and extruded. This core body 2 is obtained. The interfacial separation between cotton and polyester due to the incompatibility of heterogeneous materials can be reduced by the action of the compatibilizer. Therefore, the cotton between the core 2 can be covered with a polymer material without phase separation. The problem. In addition, because cotton has a high water content, the moisture contained in cotton will be coated in the polymer blend during the cotton and polymer kneading process, which will easily cause the quality and durability of subsequent products Good disadvantages. The present invention further uses the heat generated during the premixing of cotton and the compatibilizer to allow the moisture of the cotton to escape and be removed by air extraction. Therefore, the water content of the processed material formed after the premixing can also be effectively reduced Rate, and improve the durability and physical properties of the product.

更具體的說，該混合步驟可利用捏和方式將該粉碎後的布料與相容劑預混合以得到該加工料，或是利用是將該粉碎後的布料與相容劑置入一摩擦加熱旋轉桶中，藉由該摩擦加熱旋轉桶的轉動讓該相容劑於轉動摩擦過程升溫熔融，包覆該布料而形成該加工料。此外，該布料中棉所含的水份於摩擦升溫過程會蒸發，因此，配合於升溫過程同時進行抽氣，將水氣抽離，而可有效減少後續製得之該加工料的水氣含量。此外，當該布料是同時含有棉與聚酯時，該相容劑的熔點還可控制在低於該布料的聚酯的熔點，避免混合過程因相容劑的熔融溫度過高造成棉碳化的問題。More specifically, in the mixing step, the kneaded cloth can be pre-mixed with the compatibilizing agent to obtain the processed material by kneading, or the crushed cloth and the compatibilizing agent can be placed in a friction heating mode. In the rotary bucket, the compatibilizing agent is heated and melted during the rotary friction process by the rotation of the friction heating rotary bucket, and the cloth is covered to form the processed material. In addition, the moisture contained in the cotton in the fabric will evaporate during the friction heating process. Therefore, in conjunction with the heating process, air extraction is performed at the same time to remove the water vapor, which can effectively reduce the water vapor content of the subsequent processing material. . In addition, when the cloth contains both cotton and polyester, the melting point of the compatibilizer can also be controlled below the melting point of the polyester of the cloth to avoid carbonization of the cotton due to the high melting temperature of the compatibilizer during the mixing process problem.

該加工步驟是將該加工料與該改質劑進行混練得到一芯體材料，再將該芯體材料與該皮層材料利用共壓出方式，而得到該塑木結構。The processing step is to knead the processing material and the modifier to obtain a core material, and then use the co-extrusion method to form the core material and the skin material to obtain the plastic-wood structure.

詳細的說，因為經過該混合步驟的棉已被該相容劑包覆，而形成一可用以混煉加工的高分子加工料，因此，可將該加工料置入螺桿機中，並利用側邊入料方式令該改質劑進入該螺桿機一同進行混煉，形成一芯體材料。接著，再準備該含有親水性改質的聚烯烴或含有親水性改質聚酯的高分子摻混物的皮層材料，將該皮層材料與芯體材料利用共壓出方式進行壓出，即可得到如圖2所示的該塑木結構。其中，該芯體2是由該芯體材料構成，該皮層3則是由該皮層材料所構成。In detail, because the cotton that has passed through the mixing step has been coated with the compatibilizing agent to form a polymer processing material that can be used for kneading processing, the processing material can be placed in a screw machine and used on the side. The side-feeding method allows the modifier to enter the screw machine and be mixed together to form a core material. Next, a skin material containing the hydrophilic modified polyolefin or a polymer mixture containing the hydrophilic modified polyester is prepared, and the skin material and the core material are extruded by a co-extrusion method. The plastic-wood structure shown in FIG. 2 is obtained. The core body 2 is composed of the core material, and the skin layer 3 is composed of the skin material.

皮層材料：多元醇親水性改質聚酯(m-PET)、聚乙烯(PE)，及聚丙烯(PP)的高分子摻混物，且其比例為：m-PET:PE:PP= 50:30:20。Cortex material: polymer blend of polyol hydrophilic modified polyester (m-PET), polyethylene (PE), and polypropylene (PP), and its ratio is: m-PET: PE: PP = 50 : 30: 20.

將粉碎後的布料與相容劑置入摩擦加熱旋轉桶中，藉由該摩擦加熱旋轉桶的轉動逐漸升溫至約150~180℃，並同時抽氣，讓該相容劑熔融包覆該布料而形成一加工料。接著，將該加工料置入單軸螺桿機中，並利用側邊入料方式將該改質劑送入該單軸螺桿機中進行混煉，形成一芯體組成，最後再將該芯體組成與該皮層材料於150~160℃進行共壓出，得到如圖2所示的塑木結構。The pulverized cloth and the compatibilizer are placed in a friction heating rotary bucket, and the rotation of the friction heating rotary bucket is gradually heated to about 150-180 ° C, and at the same time, air is sucked to allow the compatibilizer to melt and coat the cloth. A processed material is formed. Next, the processed material is put into a single-screw screw machine, and the modifier is fed into the single-screw screw machine by a side feeding method for kneading to form a core composition, and finally the core body The composition and the skin material are co-extruded at 150-160 ° C to obtain a plastic-wood structure as shown in FIG. 2.

比較例1Comparative Example 1

該比較例1的製程與該具體例大致相同，不同處在於該比較例是以未改質的PET分別作為相容劑與改質劑進行混煉加工。The manufacturing process of Comparative Example 1 is substantially the same as the specific example, except that the comparative example uses unmodified PET as a compatibilizing agent and a modifying agent for kneading.

比較例2Comparative Example 2

該比較例2的芯體是利用添加木粉於高分子材料(PET)中而得。The core of Comparative Example 2 was obtained by adding wood flour to a polymer material (PET).

比較例3Comparative Example 3

該比較例3的芯體是利用添加玻纖於高分子材料(PET)中而得。The core of Comparative Example 3 was obtained by adding glass fiber to a polymer material (PET).

不同處在於該比較例是以未改質的PET分別作為相容劑與改質劑進行混煉加工。The difference is that in this comparative example, unmodified PET is used as a compatibilizing agent and a modifying agent for kneading.

參閱圖3~6，圖3~6是分別將該具體例1及比較例1~3的該芯體材料直接壓出後得到的芯體進行切片後的SEM照片。由圖4~6可明顯看出，未使用相容劑時，棉纖維、木粉及玻纖與高分子材料(PET)之間的相容性差無法被包覆而有界面分離的問題。反觀本案(如圖3所示)，因為有相容劑的輔助，所以可有效增加棉纖維與高分子材料(聚酯)之間的相容性，而讓棉纖維可較完整地被高分子材料包覆。Referring to FIGS. 3 to 6, FIGS. 3 to 6 are SEM photos of the core body obtained by directly extruding the core material of the specific example 1 and the comparative examples 1 to 3, respectively, after sectioning. It can be clearly seen from Figs. 4 to 6 that when the compatibilizer is not used, the poor compatibility between cotton fiber, wood flour, and glass fiber and the polymer material (PET) cannot be covered and there is a problem of interface separation. In contrast, this case (as shown in Figure 3), because it is assisted by a compatibilizer, it can effectively increase the compatibility between cotton fibers and polymer materials (polyester), so that cotton fibers can be more completely polymerized. Material coating.

綜上所述，本發明利用相容劑與改質劑，增加布料與塑料之間的相容性，讓布料可被相容劑及改質劑包覆而可增加芯體之強度，並讓製得的塑木結構的芯體與皮層間可有極佳的結合性，而可增加製得之塑木結構的整體強度及耐用性，此外，由於本案的布料可使用廢棄及/回收的衣物為原料，除了可再利用廢棄衣物之外還可減少該塑木結構中石化原料的使用，而可對環境更友善，故確實可達成本發明之目的。In summary, the present invention utilizes a compatibilizer and a modifier to increase the compatibility between the cloth and the plastic, so that the cloth can be covered by the compatibilizer and the modifier to increase the strength of the core, and The core and skin of the obtained WPC structure can have excellent bonding, which can increase the overall strength and durability of the WPC structure.
