Description

生質樹脂組成物、生質樹脂複合物以及生質發泡材料Bio-resin composition, bio-resin composite and bio-foamed material

本揭露是有關於一種樹脂組成物、樹脂複合物以及發泡材料,且特別是有關於一種生質樹脂組成物(bio-resin composition)、生質樹脂複合物(bio-resin composite)以及生質發泡材料(bio-foam material)。The present disclosure relates to a resin composition, resin composite, and foamed material, and more particularly, to a bio-resin composition, bio-resin composite, and biomass Foam material (bio-foam material).

對於一般具有抗靜電特性的材料來說,其是藉由將含有抗靜電劑的樹脂複合物進行混摻而得,其中所含有的抗靜電劑在樹脂中形成導電路徑,以使複合物具有抗靜電特性。For materials with antistatic properties in general, it is obtained by blending a resin compound containing an antistatic agent, and the antistatic agent contained therein forms a conductive path in the resin, so that the compound has antistatic properties. electrostatic properties.

然而,對於含有抗靜電劑的樹脂複合物來說,在發泡之後,分散於樹脂中的抗靜電劑往往因樹脂的體積增加而更為分散開,使得原複合物中的導電路徑被破壞,因而降低了發泡材料的抗靜電效果。為了解決前述問題,必須提高抗靜電劑的含量來提高導電性,除了會增加發泡材料的成本,亦會導致發泡倍率下降。However, for resin composites containing antistatic agents, after foaming, the antistatic agents dispersed in the resin tend to be more dispersed due to the increase in the volume of the resin, so that the conductive paths in the original composite are destroyed, Thus, the antistatic effect of the foamed material is reduced. In order to solve the aforementioned problems, it is necessary to increase the content of the antistatic agent to improve the electrical conductivity, which not only increases the cost of the foamed material, but also leads to a decrease in the foaming ratio.

為讓本揭露的上述特徵和優點能更明顯易懂,下文特舉實施例,並配合附圖作詳細說明如下。In order to make the above-mentioned features and advantages of the present disclosure more obvious and easy to understand, the following embodiments are given and described in detail with reference to the accompanying drawings as follows.

下文列舉實施例並配合所附圖來進行詳細地說明,但所提供的實施例並非用以限制本揭露所涵蓋的範圍。The following examples are described in detail with the accompanying drawings, but the provided examples are not intended to limit the scope of the present disclosure.

關於本文中所提到「包含」、「包括」、「具有」等的用語均為開放性的用語,也就是指「包含但不限於」。The terms "including", "including", "having", etc. mentioned in this article are all open-ended terms, that is, "including but not limited to".

此外,在本文中,由「一數值至另一數值」表示的範圍是一種避免在說明書中逐一列舉所述範圍中的所有數值的概要性表示方式。因此,某一特定數值範圍的記載涵蓋了所述數值範圍內的任意數值,以及涵蓋由所述數值範圍內的任意數值界定出的較小數值範圍。Also, herein, a range represented by "one value to another value" is a general representation that avoids listing all the values in the range in the specification. Thus, the recitation of a particular numerical range includes any number within that numerical range as well as any smaller numerical range bounded by any number within that numerical range.

本揭露實施例的生質樹脂組成物包括基質、增韌劑以及抗靜電劑。此外,在以所述生質樹脂組成物形成的生質樹脂複合物中,增韌劑分散於基質中,且抗靜電劑存在於基質與增韌劑之間的界面處及/或存在於增韌劑中。如此一來,抗靜電劑可在基質與增韌劑之間的界面處及/或在增韌劑中以連續相的方式分佈。進一步地說,由於抗靜電劑可在基質與增韌劑之間的界面處及/或在增韌劑中以連續相的方式分佈,因此當本揭露實施例的生質樹脂複合物進行發泡反應時,所形成的生質發泡材料中由抗靜電劑所形成的導電路徑不易被破壞。因此,本揭露實施例的生質發泡材料可具有良好的導電與抗靜電特性。以下將對本揭露實施例的生質樹脂組成物、生質樹脂複合物以及生質發泡材料進行說明。The green resin composition of the embodiment of the present disclosure includes a matrix, a toughening agent and an antistatic agent. In addition, in the bioresin composite formed with the bioresin composition, the toughening agent is dispersed in the matrix, and the antistatic agent is present at the interface between the matrix and the toughening agent and/or is present in the toughening agent in toughener. As such, the antistatic agent can be distributed as a continuous phase at the interface between the matrix and the toughening agent and/or in the toughening agent. Further, since the antistatic agent can be distributed in the form of a continuous phase at the interface between the matrix and the toughening agent and/or in the toughening agent, when the green resin composite of the embodiment of the present disclosure is foamed During the reaction, the conductive path formed by the antistatic agent in the formed biomass foam material is not easily damaged. Therefore, the biomass foaming material of the embodiment of the present disclosure can have good electrical conductivity and antistatic properties. The biomass resin composition, the biomass resin composite, and the biomass foaming material according to the embodiments of the present disclosure will be described below.

本揭露實施例的生質樹脂組成物包括基質、增韌劑以及抗靜電劑。在本揭露實施例中,基質例如為聚乳酸(polylactic acid,PLA),其熔融流動指數(melt flow index,MI)例如介於2 g/10 min@190 °C至10 g/10 min@190 °C之間。此外,增韌劑例如為聚己內酯(polycaprolactone,PCL)、聚丁二酸丁二醇酯(polybutylene succinate,PBS)、聚丁烯己二酸對苯二甲酸酯(polybutylene adipate terephthalate,PBAT)或其組合,其熔融流動指數介於15 g/10 min@190 °C至120 g/10 min@190 °C之間。在一實施例中,增韌劑的熔融流動指數例如介於15 g/10 min@190 °C至100 g/10 min@190 °C之間。在另一實施例中,增韌劑的熔融流動指數例如介於15 g/10 min@190 °C至80 g/10 min@190 °C之間。在又一實施例中,增韌劑的熔融流動指數例如介於15 g/10 min@190 °C至50 g/10 min@190 °C之間。也就是說,在本揭露實施例中,增韌劑的流動特性高於基質的流動特性。The green resin composition of the embodiment of the present disclosure includes a matrix, a toughening agent and an antistatic agent. In the embodiment of the present disclosure, the matrix is, for example, polylactic acid (PLA), and its melt flow index (MI) is, for example, between 2 g/10 min@190 °C and 10 g/10 min@190 between °C. In addition, the toughening agent is, for example, polycaprolactone (PCL), polybutylene succinate (PBS), polybutylene adipate terephthalate (PBAT) ) or a combination thereof with a melt flow index between 15 g/10 min@190 °C and 120 g/10 min@190 °C. In one embodiment, the melt flow index of the toughening agent is, for example, between 15 g/10 min@190 °C and 100 g/10 min@190 °C. In another embodiment, the melt flow index of the toughening agent is, for example, between 15 g/10 min @ 190 °C and 80 g/10 min @ 190 °C. In yet another embodiment, the melt flow index of the toughening agent is, for example, between 15 g/10 min @ 190 °C and 50 g/10 min @ 190 °C. That is to say, in the embodiments of the present disclosure, the flow characteristics of the toughening agent are higher than that of the matrix.

此外,在本揭露實施例的生質樹脂組成物中,基質與所述增韌劑的重量比介於90:10至60:40之間。當基質與增韌劑的重量比在上述範圍之外時,會導致材料的剛性下降且無法獲得高發泡倍率的發泡材料。In addition, in the green resin composition of the embodiment of the present disclosure, the weight ratio of the matrix to the toughening agent is between 90:10 and 60:40. When the weight ratio of the matrix to the toughening agent is outside the above-mentioned range, the rigidity of the material decreases and a foamed material with a high expansion ratio cannot be obtained.

在本揭露實施例中,抗靜電劑包括碳黑(carbon black)、奈米碳管(carbon nanotube)、石墨烯(graphene)或其組合。抗靜電劑具有良好的導電特性,因此可使得由本揭露實施例的生質樹脂組成物形成的生質樹脂複合物以及由所述生質樹脂複合物形成的生質發泡材料具有良好的抗靜電特性,以應用於具抗靜電需求的電子精密儀器、高階面板、玻璃基板、半導體產品的包裝來保護與維持電子產品的功能。在本揭露實施例中,以基質與增韌劑的總重量計,抗靜電劑的含量例如介於1%至10%之間。當抗靜電劑的含量少於1%時,由生質樹脂組成物形成的生質樹脂複合物在進行發泡反應而形成生質發泡材料之後,生質發泡材料中由抗靜電劑所形成的導電路徑會因發泡時的體積增加而被破壞。當抗靜電劑的含量高於10%時,會導致無法順利混練押出造粒、機械性能顯著下降以及難以獲得高發泡倍率的發泡材料。在一實施例中,以基質與增韌劑的總重量計,抗靜電劑的含量例如介於1%至5%之間。In the disclosed embodiment, the antistatic agent includes carbon black, carbon nanotube, graphene, or a combination thereof. The antistatic agent has good electrical conductivity, so that the bioresin composite formed from the bioresin composition of the embodiment of the present disclosure and the biofoamed material formed from the bioresin composite have good antistatic properties It is used in the packaging of electronic precision instruments, high-end panels, glass substrates, and semiconductor products with antistatic requirements to protect and maintain the functions of electronic products. In an embodiment of the present disclosure, the content of the antistatic agent is, for example, between 1% and 10% based on the total weight of the matrix and the toughening agent. When the content of the antistatic agent is less than 1%, after the biomass resin composite formed from the biomass resin composition undergoes a foaming reaction to form a biomass foam material, the biomass foam material is replaced by the antistatic agent. The resulting conductive paths are disrupted by the increase in volume during foaming. When the content of the antistatic agent is higher than 10%, it will lead to inability to smoothly knead, extrude and granulate, the mechanical properties will be significantly reduced, and it will be difficult to obtain a foamed material with a high expansion ratio. In one embodiment, the content of the antistatic agent is, for example, between 1% and 5% based on the total weight of the matrix and the toughening agent.

此外,在本揭露實施例中,增韌劑的流動特性高於基質的流動特性。因此,在由本揭露實施例的生質樹脂組成物形成的生質樹脂複合物中,抗靜電劑主要會存在於基質與增韌劑之間的界面處及/或存在於增韌劑中以連續相的方式分佈而形成導電路徑,且在形成生質發泡材料之後,仍可保持完整的導電路徑以提供良好的抗靜電特性。在本揭露實施例中,生質樹脂複合物的表面阻抗例如介於10 5Ω/sq.至10 7Ω/sq.之間。 In addition, in the embodiments of the present disclosure, the flow characteristics of the toughener are higher than the flow characteristics of the matrix. Therefore, in the bio-resin composites formed from the bio-resin compositions of the embodiments of the present disclosure, the antistatic agent is mainly present at the interface between the matrix and the toughening agent and/or in the toughening agent to continuously The conductive paths are formed by distributing in a phase manner, and after the biomass foam material is formed, the conductive paths can still be kept intact to provide good antistatic properties. In the disclosed embodiment, the surface impedance of the green resin composite is, for example, between 10 5 Ω/sq. to 10 7 Ω/sq.

在一實施例中,可使用雙螺桿押出機對本揭露實施例的生質樹脂組成物進行熔融混摻、反應押出與拉條造粒,以製成生質樹脂複合物。In one embodiment, a twin-screw extruder can be used to perform melt blending, reactive extrusion and strand granulation of the green resin composition of the embodiment of the present disclosure to form a green resin composite.

將本揭露實施例的生質樹脂複合物進行發泡反應(例如超臨界批次發泡反應),可形成本揭露實施例的生質發泡材料,其可發泡成具有10倍至30倍的體積。在本揭露實施例中,生質發泡材料的泡孔的孔徑例如介於1 μm至100 μm之間,且其密度例如介於0.02 g/cm 3至0.2 g/cm 3之間。在一實施例中,生質發泡材料的密度例如介於0.02 g/cm 3至0.15 g/cm 3之間。此外,所形成的生質發泡材料的表面阻抗例如介於10 4Ω/sq至10 7Ω/sq之間。也就是說,在進行發泡反應之後,相較於生質樹脂複合物,生質發泡材料可具有相同甚至更低的表面阻抗,且因此可具有良好的抗靜電特性。 The biomass resin composite of the embodiment of the present disclosure is subjected to a foaming reaction (eg, a supercritical batch foaming reaction) to form the biomass foamed material of the embodiment of the present disclosure, which can be foamed to a thickness of 10 times to 30 times. volume of. In the disclosed embodiment, the pore size of the cells of the biomass foam material is, for example, between 1 μm and 100 μm, and the density thereof is, for example, between 0.02 g/cm 3 and 0.2 g/cm 3 . In one embodiment, the density of the biomass foam material is, for example, between 0.02 g/cm 3 to 0.15 g/cm 3 . In addition, the surface impedance of the formed biomass foam material is, for example, between 10 4 Ω/sq and 10 7 Ω/sq. That is, after performing the foaming reaction, the biomass foamed material may have the same or even lower surface impedance compared to the biomass resin composite, and thus may have good antistatic properties.

以下將以實驗例與比較例來對本揭露的生質樹脂複合物以及由所述生質樹脂複合物經發泡反應形成的生質發泡材料進行說明。The following will describe the bio-resin composite of the present disclosure and the bio-foamed material formed by the foaming reaction of the bio-resin composite by way of experimental examples and comparative examples.
