Description

一次性發泡成形之高透氣墊體結構
本創作係為一種墊體結構，尤指一種一次性發泡成形之一體成形高透氣墊體結構。
習知之發泡墊體材質分為PU、EVA等等，其中，PU材質發泡之墊體又可分為閉孔型PU發泡體及開孔型PU發泡體，閉孔型PU發泡體於成形為墊體時，該墊體上會產生複數氣孔，但是複數該氣孔並沒有相互連通，因此該墊體並不具有透氣性，該墊體於使用上可能會令使用者感到悶熱不透氣，閉孔型PU發泡體的優點是該墊體可以根據模具的形狀進行發泡成形，不會有多餘的廢料產生，缺點是成形後並不具有透氣功效。
請參閱圖式第一圖至第四圖，另一種為開孔型PU發泡體材質，在發泡成形時，需要先發泡成一大片墊體(A)，再從整片該墊體(A)上裁切出需要的形狀及範圍，才能完成一個成品(A1)，然，開孔型PU發泡體於成形為該墊體(A)時，該墊體(A)之發泡體(A11)會產生複數相互連通之氣孔，但表皮層(A12)卻不具有氣孔，因此該成品(A1)仍不具有透氣性，如需使該成品(A1)具有 透氣性，需要先將該表皮層(A12)撕除，才具有透氣功效，露出該發泡體(A11)雖具有透氣性，卻形成表面粗糙且不耐磨損，具有透氣性之墊體的優點是具有良好的透氣性，整體觸感柔軟舒適，缺點是無法隨著模具形狀範圍一次成形，需要二次加工裁切才能完成成品，成形裁切後會有多餘的廢料產生，且需要將該表皮層撕除才具有透氣功效。
上述問題是本創作人親身感受到的缺點，本創作人關注上述問題多年，因此經過不斷研究及改良，而終有本創作之產生，以取代習知技術。
本創作目的係提供一種一次性發泡成形之高透氣墊體結構，以改善習知技術之缺點。
為達上述目的，本創作提供了一次性發泡成形之高透氣墊體結構，包括一墊體，該墊體採用發泡材質發泡成形，為一體成形之結構，該墊體發泡成形後具有發泡體及冷卻結皮之表皮層，該發泡體具有複數氣孔，複數該氣孔之間相互連通，該表皮層具有複數透氣孔，該發泡體之複數該氣孔與該表皮層之複數該透氣孔之間相互連通，使本創作之該墊體達到可完全透氣之功效。
又，該墊體解決了習知技術的缺點，又兼具有習知技術的優點，本創作之該墊體，可以隨著模具形狀範圍進行一次性發泡成形，無須再進行二次加工裁切作業， 即可得到完成品，而完成之該墊體具有高透氣性，該發泡體具有複數該氣孔，該表皮層具有複數該透氣孔，複數該氣孔與複數該透氣孔之間相互連通，令使用者使用本創作時，可以感到不同以往之完全透氣使用體驗；以下例舉一具體實施例，且佐以圖式作詳細說明，俾使審查委員能對於本創作之技術特徵，有更進一步之了解。

請參閱圖式第十圖，本創作為一次性發泡成形之高透氣墊體結構，包括一墊體(1)，該墊體(1)採用發泡材質(41)發泡成形，為一體成形之結構，該墊體(1)發泡成形後具有發泡體(11)及冷卻結皮之表皮層(12)，該發泡體(11)具有複數氣孔(111)，複數該氣孔(111)之間相互連通，該表皮層(12)具有複數透氣孔(121)，該發泡體(11)之複數該氣孔(111)與該表皮層(12)之複數該透氣孔(121)之間相互連通，使本創作之該墊體(1)達到可完全透氣之功效。
本創作之該發泡材質(41)為開孔型PU材質，該發泡材質(41)包含有第一原料組成物及第二原料組合物，該第一原料組成物包含有聚醚多元醇、擴鏈劑、催化劑、表面活性劑及發泡劑，第二原料組成物為二苯基甲烷與二異氰酸酯之預聚物，該發泡材質內含之原物料配比，即該第一原料組成物與該第二原料組成物之配比約為10：7。
透過前一段落敘述之該發泡材質(41)所製成之該墊體(1)，該墊體(1)之密度可達到0.15~0.35，比一般習知技術所能達到的密度範圍更大，該墊體(1)之耐壓縮比恢復率可達到90%~95%，也比習知技術所能達到的恢復率更高，因此該墊體(1)不僅具有高透氣性，更可根據使用需求做到密度範圍更大及高度的耐壓縮比恢復率，請參閱圖式第十一圖，透過這些特性及優點，該墊體(1)可作為鞋墊、保護墊、透氣墊等用 途使用，亦可用於其他用具上作為保護透氣之用，例如運動用品之保護內襯，本創作如作為鞋墊時，令使用者之足部(6)可以感到不同以往之完全透氣使用體驗，以取代習知技術所做成的墊體。
請參閱圖式第五圖至第九圖及第十二圖，一次性發泡成形之高透氣墊體製造方法步驟為：(A)將模具(2)打開，並利用噴槍(3)在模穴(21)上均勻噴上脫膜劑(31)；(B)將該發泡材質(41)利用輸入設備(4)灌入該模穴(21)中；(C)閉合並緊閉該模具(2)；(D)將閉合後該模具(2)置於發泡設備(5)中；(E)該發泡材質(41)於該發泡設備(5)中進行發泡成形；(F)該發泡材質(41)於發泡過程中，該墊體(1)之該發泡體(11)會形成有複數相互連通之該氣孔(111)，該墊體(1)之該表皮層(12)會與該脫模劑(31)產生反應並於該表皮層(12)上形成複數該透氣孔(121)，複數該氣孔(111)與複數該透氣孔(121)相互連通；(G)打開該模具(2)；(H)取下該墊體(1)，該發泡設備(5)為加熱裝置，透過該加熱裝置令該發泡材質(41)順利發泡成形。
整體來說，該墊體(1)解決了習知技術開孔型PU材質及閉孔型PU材質的缺點，又兼具了兩者的優點，本創作之該墊體(1)，可以隨著模具形狀範圍進行一次性發泡成形，無須再進行二次加工裁切作業，即可得到完成品，而完成之該墊體(1)具有高透氣性，該發泡體(11)具有複數該氣孔(111)， 該表皮層(12)具有複數該透氣孔(121)，複數該氣孔(111)與複數該透氣孔(121)之間相互連通，令使用者使用本創作時，可以感到不同以往之完全透氣使用體驗；上述實施例僅為說明本創作之原理及其功能，並非限制本創作，因此習於此技術之人士對上述實施例進行修改及變化，仍不脫本創作之精神；本創作已具備產業上利用性、新穎性及進步性，並符合新型專利要件，爰依法提起申請。
