Description

添加有生物树脂的汽车用内饰片及其制备方法
技术领域
本发明涉及添加有生物树脂的汽车用内饰片及其制备方法，尤其涉及除了需要各种机械特性的车辆用表皮材料的产品性能、压纹质量、触觉等感官品质之外，在CO2及总挥发性有机化合物(TVOC)的减少方面发挥卓越的性能，由此适合制备汽车的仪表板(Instrument Panel)、下部板(Lower Panel)、控制箱(Console Box)、座套(seat cover)、门(door)等的表皮材料等的添加有生物树脂的汽车用内饰片及其制备方法。
背景技术
通常，在汽车的仪表板(Instrument Panel)、下部板(Lower Panel)、控制箱(Console Box)、座套(seat cover)、门(door)等的表皮材料的表皮中除了座套之外的产品大部分将由PVC(聚氯乙烯)或TPO(热塑性聚烯烃)制备的薄片进行真空成型而成，或者通过PVC、TPU(热塑性聚氨酯)粉末凝塑工艺制备而成。
并且，座套的情况下，通常，使用PVC、PU(聚氨酯)人造革或质地(texture)、皮革等材料来进行加工。
相反，生物片(Bio sheet)与现有的表面材料表皮相比，所需物性及作业性并不下降，且使用来源于植物的树脂，因而既环保又有助于制备对人体无害的内饰用材料。
当前，已知生物(bio)树脂因其特性而难以软化，且因被阳光及水分解的性质而主要用于一次性产品，而作为需要耐久性的工业用塑料，主要用在见不到光的地方(脚垫、后备箱)。
因此，急需作为汽车用内饰表皮材料的汽车用内饰片，在上述汽车用内饰片中，将来源于植物的生物(bio)树脂和作为内饰材料的性能得到认定的TPU、TPO树脂混合之后，通过电子束(EB，Electro Beam)交联使物性加倍，由此在不降低物性的情况下，能够减少CO2的产生，并提高空气质量。

以下，利用本发明的实施例，并参照用于说明添加有生物树脂的汽车用内饰片及其制备方法的附图，对本发明进行说明。
本发明一实施例的添加有生物树脂的汽车用内饰片100的特征在于，包含：5～100重量份的由从玉米、土豆、红薯、甘蔗、竹子或与它们类似的品种中的一种以上的天然植物提取的淀粉取得的生物树脂；30～100重量份的热塑性聚烯烃(TPO，Thermoplastic Polyolefin)树脂或热塑性聚氨酯(TPU，Thermoplastic Polyurethane)树脂；5～40重量份的相容剂；0.1～1.5重量份的润滑剂；以及0.5～5重量份的交联剂。
在这里，上述生物树脂可使用聚乳酸(PLA，Poly Lactic Acid)、聚丁二酸丁二醇酯(PBS，polybutylene succinate)、生物聚乙烯(bio-Polyethylene)、从玉米、土豆、红薯、甘蔗、竹子及与它们类似的品种中的一种以上的天然植物提取的树脂或聚羟基脂肪酸酯(PHA，Poly-hydroxy alkanoate)中的一种以上。
并且，上述热塑性聚烯烃(TPO，Thermoplastic Polyolefin)树脂可以为乙烯辛烯橡胶(EOR，ethylene octene rubber)、聚丙烯(PP，polypropylene)基的热塑性硫化橡胶(TPV，Thermoplastic Vulcanizate)或P基的热塑性硫化橡胶(TPV，Thermoplastic Vulcanizate)中的一种。
并且，上述热塑性聚氨酯(TPU，Thermoplastic Polyurethane)树脂中，多元醇(polyol)可以为聚碳酸酯(PC，polycarbonate)类、醚(ether)类及酯(ester)类中的一种。
并且，上述相容剂可以为甲基丙烯酸缩水甘油酯(GMA，glycidylmethacry late)、马来酸酐(MAH，maleic anhydride)、马来酸(MA，maleic acid)、乙烯-甲基丙烯酸甲酯共聚物中的一种。
并且，上述交联剂可以为三烯丙基异氰脲酸酯(TAIC，triallylisocyanurate)、三羟甲基丙烷三丙烯酸酯(TMPTA，trimethylolpropanetriacrylate)、己二醇二丙烯酸酯(HDDA，hexandiol diacrylate)、三芳基氰尿酸酯(TAC，triallylcynurate)及三丙二醇二丙烯酸酯(TPGDA，tripropylene glycol diacrylate)中的一种。
并且，本发明一实施例的添加有生物树脂的汽车用内饰片的制备方法的特征在于，包括：步骤S10，将生物树脂、热塑性聚烯烃树脂或热塑性聚氨酯树脂、相容剂、润滑剂、交联剂进行配合；步骤S20，将配合好的材料制备成颗粒(pellet)；步骤S30，借助挤压机或压延机来将上述颗粒制备成薄片(sheet)；以及步骤S40，将上述薄片(sheet)型的材料进行固化。
在这里，进行配合的上述步骤S10借助加压捏合机、密炼机或挤压机实现，进行固化的上述步骤S40借助电子束(EB，Electro Beam)照射器实现，此时，在固化好的上述步骤S40中，借助上述电子束照射器所吸收的放射线能量的量在10～100kGy的范围内。
如上所述，根据利用电子束照射器40来进行固化的步骤S40，从上述电子束照射器40所放射的放射线向上述薄片(sheet)式的材料照射，由此，随着组成材料的各聚合物的每个链变为网状的分子结构，拉伸强度等机械特性也得到提高。
并且，本发明一实施例的添加有生物树脂的汽车用内饰片的制备方法的特征在于，还包括：步骤S50，在固化好的材料的表面涂敷丙烯酸(Acryl)类或氨基甲酸乙酯(Urethane)类的树脂；以及步骤S60，对涂敷好的材料的表面进行压纹处理。
在这里，根据进行涂敷的上述步骤S50，能够防止表面刮痕(Scratch)的产生，从紫外线(UV)保护材料，并提高光泽效果，根据进行压纹处理的上述步骤S60，能够实现天然皮革花纹或几何学花纹等。
只要是本发明所属技术领域的普通技术人员，就能够理解在不变更技术思想或必要特征的情况下，能够以不同的具体方式实施本发明。
因此，应理解为如上所述的实施例在所有方面仅是例示性的，而非限定。
本发明的范围由发明要求保护范围表示，而不是上述详细的说明，应解释为从发明要求保护范围的含义及范围和其等同概念导出的所有变更或变形形态都属于本发明的范围。
