Description

环保无废料的发泡鞋材制造方法，及其鞋材半成品与鞋体成品 技术领域
本发明与鞋材制造技术有关，特别指一种环保无废料的发泡鞋材制造方法，及其鞋材半成品与鞋体成品。
背景技术
已知目前制鞋业概将鞋底分为上层的鞋中底以及下层的鞋大底，其中所述鞋中底与所述鞋大底，为达舒适性及耐用性等需求，通常选用橡胶或乙烯-醋酸乙烯共聚物(EVA)，TPE(热塑性弹性体)、合成橡胶(synthetic rubber)等发泡材料制成。
目前制鞋业的鞋大底制法，是将前述发泡材料利用押出机以高温高压射出发泡模具中进行一次性发泡成型；然而，在射出发泡制程中，所述发泡材料是经由所述发泡模具的入料道进入模室中，如此所述入料道中的发泡材料经由发泡而产生发泡废弃物，由于所述发泡废弃物无法进行再生处理，在制鞋业每天生产大量鞋大底的情况下，同时大量产生前述发泡废弃物会造成环境污染的问题。
此外，前述一次性发泡技术中无法将所述发泡材料对所述发泡模具进行精准投料，使得所述发泡材料在发泡过程容易产生溢料，爆边以及空气滞留模穴的包气问题，使得鞋大底的不良率大致介于6％～10％左右，这些不良的鞋材或鞋品造成对用材极大的耗损以及环境的负担。
综上可知，一般鞋底的制法仍未臻完善，尚有待改进之处。
发明内容
有鉴于此，本发明的目的在于提供一种环保无废料的发泡鞋材制造方法，及其鞋材半成品与鞋体成品，所述发泡鞋材制造方法能够在不降低鞋材物性的前提下，将制程中的废料循环就地绞碎回收再利用，提供环境保护的效益，更可提高所述鞋体成品良率。
缘以达成上述目的，本发明提供的环保无废料的发泡鞋材制造方法，包括下列步骤：步骤S1，将一橡塑发泡材料以射出方式填充在一粗胚模具的模室中固化成型，制得未发泡的一鞋材半成品及一射出制程流道废料射出制程流道废料，其中所述射出制程流道废料能够回收绞碎，再次制成所述橡塑发泡材料；以及步骤S2，冷却所述鞋材半成品，且将其置入于一发泡模具中均匀发泡，获取一鞋体成品。
本发明另一实施例提供一种鞋材半成品，其为未发泡成型体，所述鞋材半成品划分有多个区段，所述多个区段包含一前区段、一后区段，及一中区段位于所述前区段与所述后区段 之间，所述前区段、所述后区段及所述中区段中的任意两者的密度差异比例介于1～3％。
本发明又一实施例提供一种鞋体成品，是一发泡体，所述发泡体划分有多个区段，所述多个区段包含一前足区段、一后足区段，及一足弓区段位于所述前足区段与所述后足区段之间，所述前足区段、所述后足区段及所述足弓区段中的任意两者的密度差异比例介于1～3％。
本发明的效果在于，所述步骤S1中所制得所述射出制程流道废料为未发泡产物，所以所述射出制程流道废料能经由就地回收经绞碎处理，不须经过重新造粒流程，再投入射出机中即能再次制成橡塑发泡材料未发泡的鞋材半成品，致使所述射出制程流道废料具备实用价值，有效地减少所述发泡鞋材制造方法产生不可回收的废弃物，除了提供环境保护的效益，更可达到循环经济的功效。
此外，所述鞋材半成品中的所述多个区段彼此密度实质上相同，致使所述鞋材半成品整体密度均匀分布，借以所述鞋材半成品经由发泡定型，而能一次性完成发泡完全的所述鞋体成品，提高所述鞋体成品良率。

具体实施方式
为能更清楚地说明本发明，兹举优选实施例并配合附图详细说明如后。请参考图1，为本发明提供一种环保无废料的发泡鞋材制造方法，再请参考图2、6，是本发明利用所述发泡鞋材制造方法鞋材制得的鞋材半成品10与鞋体成品20。本发明所述环保无废料的发泡鞋材制造方法包括下列步骤：
步骤S1，将一橡塑发泡材料以射出方式均匀填充在一粗胚模具(图中未示)的模室中固化成型，制得未发泡的所述鞋材半成品10(参图2)及一射出制程流道废料(图中未示)；具体说明，在本实施例中，所述橡塑发泡材料包含乙烯-醋酸乙烯共聚物(EVA)、合成橡胶(Synthetic Rubber)及热塑性弹性体(TPE)的其中一种，且所述橡塑发泡材料是控制在螺杆温度低于130℃的条件下射出成型；由于所述橡塑发泡材料的发泡温度约为160℃以上，因而所述橡塑发泡材料控制在螺杆温度低于130℃的条件下射出不会产生发泡反应，且所述橡塑发泡材料在射出过程控制射出压力的输出，而能使射出的橡塑发泡材料均匀分布在所述粗 胚模具(图中未示)的模室中固定形成所述鞋材半成品10，其中所述鞋材半成品10可为鞋大底粗胚、鞋垫粗胚、拖鞋粗胚及一体成形全鞋粗胚中的一种，但不限于此；如图2所示，在本实施例中，所述鞋材半成品10是以运动鞋大底粗胚作为说明。
如图2所示，特别说明地，本发明所述鞋材半成品10是未发泡成型体，且所述鞋材半成品10针对所述鞋材半成品10的密度分布进行检测，将所述鞋材半成品10划分有多个区段，所述多个区段包含一前区段P1、一后区段P2，及一中区段P3位于所述前区段P1与所述后区段P2之间，所述前区段P1、所述后区段P2及所述中区段P3分别通过密度测试发现，所述前区段P1、所述后区段P2及所述中区段P3中的任意两者的密度差异比例介于1～3％，由此可知，所述步骤S1所制得所述鞋材半成品10中的所述多个区段彼此密度实质上相同，致使所述鞋材半成品10整体密度均匀分布。
在其他实施例中，所述鞋材半成品10的区段数量可为依需求调整变化，只要能够针对不同区段发泡后成品检测密度即可。
另外，由于所述粗胚模具的入料道中形成所述射出制程流道废料为未发泡产物，所以所述射出制程流道废料还能经由破碎处理，不须经过重新造粒流程，再就地通过射出机溶解并射出，即能再次制成所述鞋材半成品进行后续发泡，致使所述射出制程流道废料具备实用价值，有效地减少所述发泡鞋材制造方法产生不可回收的废弃物，如此一来，本发明所述发泡鞋材制造方法除了提供环境保护的效益，更可达到循环经济的功效。
步骤S2，冷却所述鞋材半成品10，且将冷却后的所述鞋材半成品10置入于一发泡模具100中均匀发泡(参图3至6)，获取所述鞋体成品20；具体说明，所述鞋材半成品10从所述粗胚模具取出后需先静置一个小时以上，让所述鞋材半成品10完全冷却后方可置入所述发泡模具100中使用，如图3、4所示，本实施例是将所述鞋材半成品10置放在所述发泡模具100的一下模具110的模穴111中，所述发泡模具100以低于10cm/s速度将一上模具120朝所述下模具110方向闭合，让所述鞋材半成品10的表面在模具闭合前预先在所述下模具110的模穴111中加热软化，如图5所示，且在所述上模具120与所述下模具110完全闭合时，所述鞋材半成品10完全填满所述发泡模具100的模室，且所述发泡模具100的发泡温度介于150～200℃，使得所述鞋材半成品10发泡形成所述鞋体成品20。
此外，本发明所述发泡鞋材制造方法在所述步骤2中设计所述鞋材半成品10的体积与所述下模具110的模穴111容积的比值介于0.96～1.04，在本实施例中，所述鞋材半成品10的体积等于所述下模具110的模穴111容积，由于所述鞋材半成品10在冷却过程会些微缩小体积，所以所述鞋材半成品10的体积与所述下模具110的模穴111容积会产生有些许误差；整体而言，利用所述鞋材半成品10的体积与所述发泡模具100的模穴111容积设计，让所述鞋材半成品10对所述发泡模具100精准投料，使得所述鞋材半成品10在所述发泡模具100中均匀发泡，且所述鞋材半成品10对应所述发泡模具100的分模线口不会产生溢料，即能一次性获取发泡完全的所述鞋体成品20(参图5)，以致所述鞋体成品20后续不需再次进行修边处理，使得本发明所述发泡鞋材制造方法在所述步骤2中不会额外产生任何发泡的废料。
如图6及8所示，由上述步骤可知，本发明所述鞋体成品20是一发泡体21由未发泡的所述鞋材半成品10经发泡而一体成型，且所述发泡体21是鞋大底；但在其他实施例中，所述鞋体成品20的型态可依需求制成拖鞋及包鞋；本实施例针对所述鞋体成品20的密度分布进行检测，将所述发泡体21划分有多个区段，所述多个区段包含一前足区段P1’、一后足区段P2’，及一足弓区段P3’位于所述前足区段P1’与所述后足区段P2’之间；如图7所示，所述发泡体21具有一脚床面211，所述脚床面211的一侧具有一前侧缘212，所述脚床面211的另一侧具有一后侧缘213，所述发泡体定义有一第一假想面A1以及一第二假想面A2，所述第一假想面A1位于所述脚床面211的一侧且通过所述前侧缘212，所述第二假想面A2通过所述脚床面211，使所述第一假想面A1与所述第二假想面A2间形成所述前足区段P1’，且所述发泡体21定义有一第三假想面A3以及一第四假想面A4，所述第三假想面A3远离所述前侧缘212位于所述脚床面211的另一侧且通过所述后侧缘213，所述第四假想面A4通过所述脚床面211，使所述第三假想面A3与所述第四假想面A4间形成所述后足区段P2’，且所述第二假想面S与所述第四假想面A4间形成所述足弓区段P3’。
其中所述前足区段P1’、所述后足区段P2’及所述足弓区段P3’分别通过密度测试发现，所述前足区段P1’、所述后足区段P2’及所述足弓区段P3’中的任意两者的密度差异比例介于1～3％，由此可知，所述步骤S2所制得所述鞋体成品20整体密度均匀分布，且能一次性完成发泡完全的所述发泡体21，提高所述鞋体成品20良率。
借由本发明的设计，所述环保无废料的发泡鞋材制造方法在步骤S1所制得所述射出制程流道废料为未发泡产物，所以所述射出制程流道废料能经由就地回收作绞碎处理再制成所述橡塑发泡材料，致使所述射出制程流道废料具备实用价值，有效地减少所述发泡鞋材制造方法产生不可回收的废弃物，除了提供环境保护的效益，更可达到循环经济的功效。
再者，所述鞋材半成品10中的所述多个区段彼此密度实质上相同，致使所述鞋材半成品10整体密度均匀分布，借以所述鞋材半成品10经由发泡定型，而能一次性完成发泡完全的所述发泡体21，提高所述发泡鞋材制造方法的制造良率。
以上所述仅为本发明优选可行实施例而已，举凡应用本发明说明书及申请专利范围所为的等效变化，理应包含在本发明的专利范围内。
