Description

全水发泡鞋材制法与全水发泡鞋材
技术领域
本发明有关于一种发泡鞋材的制法与一种全水发泡鞋材。
背景技术
一般来说，鞋垫或鞋中底在鞋体中扮演了相当重要的角色，因为鞋垫能够吸震、缓冲，以提供使用者脚部较为舒适的穿著感受，而鞋垫的吸震能力与回复力与其材质关系密切；此外，鞋垫的密度更影响了同等体积的鞋垫的重量，太重的鞋垫纵使吸震缓冲能力良好，仍会对使用者造成极大的负担，进而影响行走、跑跳的表现与感受。
已知的鞋垫或鞋中底等鞋材常以塑料发泡制成，例如TPU或EVA等，然而，已知的鞋垫若要具有水准之上的物性，其发泡密度通常大于0.32g/cc，且压缩比通常大于15％，在轻量化的表现上实在有待加强。
发明内容
本发明的目的是提供一种全水发泡鞋材制法，能提供更为轻量但仍能保持高物性的鞋材。
为实现上述目的，本发明采取以下技术方案：
本发明提供一种全水发泡鞋材制法，包含以下步骤：
制备主剂与硬化剂：制备一主剂与一硬化剂，其中该主剂是由聚四亚甲基聚醚二醇(PTMEG)、全水发泡剂与催化剂所混合而成，该硬化剂由聚酯多元醇与二苯基甲烷二异氰酸酯(MDI)所预聚合而成。
灌注发泡：将该主剂与该硬化剂以100：50～60的重量比经一灌注机注入一模具中发泡成型为一鞋材。
脱模：将该鞋材自该模具中取出，其中该鞋材的比重介于0.2至0.28g/cc。
所述主剂中聚四亚甲基聚醚二醇的重量百分比95％至98％，全水发泡剂的重量百分比2％至3％，催化剂的重量百分比0.2％至1％。
所述主剂中聚四亚甲基聚醚二醇的重量百分比96.9％，全水发泡剂的重量百分比2.5％，催化剂的重量百分比0.6％
所述硬化剂中聚酯多元醇的重量百分比20％至40％，二苯基甲烷二异氰酸酯的重量百分比60％至80％。
所述硬化剂中聚酯多元醇的重量百分比30％，二苯基甲烷二异氰酸酯的重量百分比70％。
所述硬化剂中的聚酯多元醇选自由己二酸聚酯多元醇与聚己内酯多元醇所组成的群组。
所述硬化剂中的聚酯多元醇选用平均分子量2000。
所述鞋材的比重介于0.22至0.25g/cc。
一种全水发泡鞋材，是以所述的全水发泡鞋材制法所制成。
本发明的有益效果是：藉此，本发明提供的全水发泡鞋材制法能提供极为轻量、但物性良好的鞋材。
附图说明
图1为本发明的流程图。
附图标号：S1：制备主剂与硬化剂；S2：灌注发泡；S3：脱模。
具体实施方式
以下仅以实施例说明本发明可能的实施态样，然并非用以限制本发明所欲保护的范畴，合先叙明。
请参考图1，本发明提供一种全水发泡鞋材制法与以该制法所制成的全水发泡鞋材，该制法包含以下步骤：
制备主剂与硬化剂S1：制备一主剂与一硬化剂，其中该主剂是由聚四亚甲基聚醚二醇(PTMEG)、全水发泡剂与催化剂所混合而成，该硬化剂由聚酯多元醇与二苯基甲烷二异氰酸酯(MDI)所预聚合而成。其中，该主剂中聚四亚甲基聚醚二醇的重量百分比95％至98％，全水发泡剂的重量百分比2％至3％，催化剂的重量百分比0.2％至1％，较佳者，该主剂中聚四亚甲基聚醚二醇的重量百分比96.9％，全水发泡剂的重量百分比2.5％，催化剂的重量百分比0.6％；该硬化剂中聚酯多元醇的重量百分比20％至40％，二苯基甲烷二异氰酸酯的重量百分比60％至80％，较佳者，该硬化剂中聚酯多元醇的重量百分比30％，二苯基甲烷二异氰酸酯的重量百分比70％；其中，该硬化剂中的聚酯多元醇选自由己二酸聚酯多元醇与聚己内酯多元醇所组成的群组，且平均分子量约2000。
灌注发泡S2：将该主剂与该硬化剂以100：50～60的重量比经一灌注机(高速搅拌混合)注入一模具中发泡成型为一鞋材(例如可经由烘箱加热)。
脱模S3：将该鞋材自该模具中取出，其中该鞋材的比重介于0.2至0.28g/cc(较佳为0.22至0.25g/cc)。
以下兹以已知PU发泡鞋材与本发明的鞋材的测试结果予以比较，可看出本发明的鞋材的优势。
首先，下表为现有PU发泡鞋材的三种样品的测试结果：
再请参考下表所列的本发明鞋材的测试结果(其中，水解的试验条件为温度80℃、湿度95％)：
由上揭测试结果可以看出，相较于已知PU发泡鞋材，本发明提供的鞋材比重明显较小，足见其轻量化的功效；另外，本发明提供的鞋材的压缩比小于10，相较于已知结构的最佳压缩比16而言，本发明有更高幅度的低压缩比特性，可确保鞋材长时间穿着下，仍不会造成鞋底压缩、变形的不耐穿问题；然而，在保有轻量化之余，其余物性皆不逊于已知PU发泡鞋材，能高幅提高目前业界鞋用中、大底发泡材的高标准，让利用本发明制程制造的发泡鞋材制成发泡鞋时，达到穿着走路更轻盈无负担，其低压缩比的高回复性，又可兼具高缓冲、吸震的走路舒适性双重特质。
综上所述，本发明的全水发泡鞋材制法所制成的鞋材具有明显较佳的轻量效果，且其他物性又能维持，作为鞋中底发泡材之用极为优异。
