Description

多層吸音減震墊
本發明有關於一種多層吸音減震墊，尤指一種施作於建築分戶樓板、牆壁隔間、牆立系統之多層吸音減震墊。
目前各大都市之新建案均以集合式住宅為主流，以求在有限之空間中容納更多住民。集合式住宅各戶緊密，住民活動時不免因跑跳、傢俱碰撞或摩擦地板，而對鄰居造成噪音干擾。因應此一問題，中華民國內政部營建署規定新建或增建連棟住宅、集合住宅之分戶牆、分戶樓板及昇降機道、機房與居室相鄰之牆及樓板等，均應加設隔音設計，以強化住屋安寧舒適，減少住戶間彼此干擾及影響。隔間系統之施作，大略以剛性建材夾襯具有吸音、減震效果緩衝材為大宗。工法上，概略可分為乾式工法(如矽酸鈣板、石膏板搭配隔音棉)與濕式工法(如水泥纖維板搭配輕質灌漿材等)兩類。整體而言，採用濕式工法之隔間系統對大部分噪音相對乾式工法有較佳的吸收效果。
如歐盟公告第EP2969533B1號發明專利案，其提供一種複合材料，其包含一層非織物，與固定在非織物上的發泡材。該複合材料具有防火及隔音功能，然因非織物與發泡材皆具有多空隙，水泥澆灌時容易滲入空隙中，使非織物與發泡材局部固化失去彈性，進而減損其隔音減震功能。
又如公開第201924894號發明專利申請案提供一種層板結構，包含兩個水泥板體及一個夾置於其間之減震墊，該減震墊是裁切後之廢棄泡棉經重壓後再熱壓製得。該減震墊經熱壓後表面不具有孔隙，雖能避免水泥進到減震墊內部，卻也導致接觸減震墊部分之水泥難以完全乾燥，而可能有水氣殘留在減震墊內。長時間下來殘留之水氣可能會慢慢滲出，而在如磁磚填縫等處發生白華現象。
再如日本公告第JP6526922B2號特許案提供一種吸音材料，在其一實施例中，其具有浸漬水溶性聚合物之不織布基材、一以液體塗佈於該不織布基材一側表面且散佈有填料之熱固性樹脂，並經層壓後結為一體。其中該填料與熱固性樹脂產生表面張力，以避免層壓時熱固性樹脂由不織布基材表面滲出而降低離型性，從而改善吸音表皮材料之外觀性。然而若採該項技術方案，將該吸音材料作為樓板隔間使用，經層壓後之不織布基材其表面較光滑平整，與水泥結合性不佳，則該吸音材料可能因樓板長期承受應力、地震等因素，致使不織布基材、樹脂膜及吸音基材等工件發生分離變形等問題。
顯然，就目前技術領域中尚無同時具備良好吸音減震功能、抗白華及工件穩定性之技術方案。因此，先前技術實有改進之必要。
本發明之目的，在於解決習用減震墊因水泥滲入吸音材料減損吸音效果、水泥水份不易逸散造成白華、以及吸音減震材料與水泥結合性不理想致使工件扭曲變形等問題。
為達上述目的，本發明提供一種多層吸音減震墊，包含有一緩衝層、二分別設置於該緩衝層相對兩側之防水透濕層、以及二分別設置於每一該防水透濕層遠離該緩衝層之一側之表層。其中該緩衝層、每一該防水透濕層以及每一該表層係由針軋結合為一體。
進一步地，每一該表層可供澆灌之水泥滲入並於乾燥後與水泥連接。
進一步地，每一該表層包含有複數預軋纖維，每一該預軋纖維藉由針軋自其中一該表層穿設於該緩衝層與每一該防水透濕層，並纏結至另一該表層。
進一步地，每一該表層之預軋纖維之材質係選自聚丙烯(polypropylene)、聚乙烯(Polyethylene)、聚醯胺(Polyamide)或聚對苯二甲酸乙二酯(polyethylene terephthalate)纖維所構成之群組。
進一步地，該緩衝層之材質係選自橡膠、發泡材質、玻璃棉、岩棉、纖維體或其組合所構成之群組。
進一步地，該緩衝層包含有複數橡膠碎粒，以及熔融於每一該複數橡膠碎粒之熱塑性彈性體。
進一步地，該緩衝層之材質係選自聚氯乙烯(Polyvinyl chloride)、聚烯烴(polyolefin)、熱塑性聚胺酯(thermoplastic polyurethane)、熱塑性聚烯烴(thermoplastic polyolefin)、苯乙烯-丁二烯-苯乙烯(styrene-butadiene-styrene)、苯乙烯-異戊二烯-苯乙烯(styrene-isoprene-styrene)、苯乙烯-乙烯/丁烯-苯乙烯(styrene-ethylene/butene-styrene)、氫化苯乙烯-丁二烯-苯乙烯(hydrogenated styrene- Butadiene-styrene)、丙烯腈-丁二烯-苯乙烯(acrylonitrile-butadiene-styrene)、丙烯腈-丁二烯橡膠(acrylonitrile-butadiene rubber)、氯丁二烯橡膠(chloroprene rubber)、海帕隆(Hypalon)、天然橡膠(natural rubber)、丁基橡膠(butyl rubber)、交聯反應型彈性體(crosslinking reaction type elastomer)或其摻合物所構成之群組。
進一步地，每一該防水透濕層之材質係選自聚胺酯甲酸基(Polyurethane formic acid-based)薄膜、鐵氟龍(Teflon)薄膜、熱塑性樹脂(thermoplastic resin)薄膜、熱塑性塑膠(thermoplastic plastic)薄膜、聚氨酯(polyurethane)薄膜或其組合所構成之群組。
進一步地，該防水透濕層係為多孔隙結構。
進一步地，其中每一該表層遠離該防水透濕層、該緩衝層之至少一側表面為非平面。
本發明多層吸音減震墊之非織物表層可供水泥澆置，並在固化後與水泥穩固連接。防水透濕層可避免水份進入緩衝層，且同時藉由透濕效果將多餘水份擴散或對流排乾。該緩衝層、每一該防水透濕層以及每一該表層藉由針軋結合為一體，透過每一該表層之間彼此之預軋纖維纏結而能穩固工件連接性，並保持吸音制震效果。
茲就本申請案的技術特徵暨操作方式舉數個較佳實施態樣，並配合圖示說明謹述於后，俾提供審查參閱。再者，本發明中之圖式，為便於說明其比例未必按實際比例繪製，圖式中之比例並不用以限制本發明所欲請求保護之範圍。
關於本發明之技術，請參照第1圖所示。於本實施態樣中，本發明提供一種多層吸音減震墊100。本發明之多層吸音減震墊100係鋪墊於建築樓板或牆面作為震動與噪音之吸收體，並在該多層吸音減震墊100外表面澆置水泥予以固定。該多層吸音減震墊100包含有一緩衝層10、二分別設置於該緩衝層10相對兩側之防水透濕層20、以及二分別設置於每一該防水透濕層20遠離該緩衝層10之一側之表層30，其中該緩衝層10、每一該防水透濕層20以及每一該表層30係由針軋結合為一體。
更詳言之，該緩衝層10之材質可為塑橡膠彈性體、發泡材質、玻璃棉、岩棉、纖維體或其組合。該緩衝層10之材質為聚氯乙烯(PVC)、聚烯烴、熱塑性聚胺酯(TPU)、熱塑性聚烯烴、苯乙烯-丁二烯-苯乙烯、苯乙烯-異戊二烯-苯乙烯(SIS)、苯乙烯-乙烯/丁烯-苯乙烯(SEBS)、氫化苯乙烯-丁二烯-苯乙烯、丙烯腈-丁二烯-苯乙烯(ABS)、丙烯腈-丁二烯橡膠、氯丁二烯橡膠、海帕隆、天然橡膠、丁基橡膠、交聯反應型彈性體或其摻合物。考量環境保護及永續發展之精神，及符合綠建材規格之需求，該緩衝層10之材質優選地為前述材質中不含鹵素者。該緩衝層10具有彈性，當衝擊產生之震波傳播至該緩衝層10時將產生阻尼效果，使震波波幅衰減。且該緩衝層10內部較佳可為多孔隙結構，使震波傳遞路徑上產生多次局部反射與抵銷，提高聲耦合阻抗達到吸音效果。優選地，該緩衝層10包含有複數橡膠碎粒，以及熔融於每一該複數橡膠碎粒之熱塑性彈性體，所述橡膠碎粒可由廢棄輪胎切碎後取得，且經熱熔後自然形成前述之多孔隙結構，無須額外加工，而有可資源回收利用之優點。該熱塑性彈性體可為聚丙烯(PP)、聚乙烯(PE)、聚碳酸酯(PC)、聚苯乙烯(PS)、丙烯腈-丁二烯-苯乙烯(ABS)共聚物、聚醯胺(PA)等，用以將該些橡膠碎粒黏固成一體。且該熱塑性彈性體與該些橡膠碎粒混合後，其彈性可進一步提高該些橡膠碎粒之吸震效果。
每一該防水透濕層20之材質係選自聚胺酯甲酸基薄膜、鐵氟龍薄膜、熱塑性樹脂薄膜、熱塑性塑膠薄膜、聚氨酯薄膜或其組合所構成之群組。其具有抗水壓能力以及透濕性。本實施態樣中，該防水透濕層20具有一定程度之耐水壓能力，使水泥澆灌時水份不會滲入該緩衝層10。優選地，該防水透濕層20之透濕度(Moisture vapor transmission rate, M.V.T.R.，ASTM E96-BW)介於100~5000g/m2. 24hrs之間，在水泥澆灌後，餘留在每一該防水透濕層20與每一該表層30間之水份及水蒸氣會受該防水透濕層20擴散至外緣，或由該防水透濕層20內部之多孔結構產生對流蒸散，幫助水泥乾燥，避免水份殘留於該多層吸音減震墊100內而造成白華結晶，或因水蒸氣造成表面貼附之磁磚膨拱等問題等問題。此外，本發明之多層吸音減震墊100鋪設於樓地板後，可直接於其上灌水泥漿。相對傳統工法需先在樓地板澆灌一道水泥基層後，再鋪設吸音墊，本發明之多層吸音制震墊100具有簡化工序之優勢。
本實施態樣中，每一該表層30包含有複數預軋纖維31，本實施態樣中，每一該表層30之每一該預軋纖維31之材質係選自聚丙烯、聚乙烯、聚醯胺或聚對苯二甲酸乙二酯纖維所構成之群組。每一該預軋纖維31受鉤針(圖未示)等針體自其中一該表層30被遷移出，並穿設於該緩衝層10與每一該防水透濕層20，再與另一該表層30之每一該預軋纖維31彼此纏結。所屬技術領具通常知識者當可理解，該多層吸音制震墊100之強度、厚度等機械條件，以及其使用於針軋製程之針軋板上之針密度、針徑等參數，應依實際上施作濕式工法隔間、牆立系統之需求調整，在此不予詳述。針軋前，每一該表層30係為係為預軋纖維結構體，本發明之用語「預軋纖維結構體」係指由每一該預軋纖維31經預處理後結合成形狀大致固定之纖維集合體，如纖維網、纖維團等。經針軋後，每一該表層30仍具有一定蓬鬆性質並留有孔隙。水泥澆灌時將滲入受澆灌之該表層30之蓬鬆孔隙間，待水泥乾燥硬化後即與該表層30結合為一體，殘餘的水氣則由每一該防水透濕層20帶出。藉上述結構，鄰近水泥之每一該表層30與水泥穩固結合之後，該多層吸音減震墊100即便承受傢俱擺設重量所產生之應力，因每一該預軋纖維31穿過該多層吸音減震墊10並將之纏結為一體，而能消化應力，令該多層吸音減震墊100不會有曲翹、脫層、變形或與水泥分離等問題。
此外，為進一步提升吸音減震效果，其中每一該表層30遠離該防水透濕層20與該緩衝層10之至少一側表面為非平面301。本實施態樣中，該非平面301係對應於樓地板，亦即遠離水泥澆灌之一側。因此，該多層吸音減震墊100鋪設於樓地板時，該非平面301與樓地板之間會形成空隙。當震動或噪音通過該非平面301與樓板之間時，空隙所產生之介面將會令震動或聲波產生反射與散射現象，令其波幅再次削減。另外，本發明不限制該非平面301之形成方式。如第1圖所示之實施態樣，該緩衝層10之一側係製成非平坦形狀後，再將每一該防水透濕層20、每一該表層30服貼於該緩衝層10之非平坦面上，以間接形成該非平面301。或如第2圖所示，於本發明之第二實施態樣中，使用者得採壓紋方式，於其中一該表層30遠離每一該防水透濕層20之一側上直接形成該非平面301。是以，只要在每一該表層30外表面形成該非平面301，即屬本發明所訴求之技術內容，該外表面之形成方式於本發明申請專利範圍中並不予以限制。
請參照第3圖所示，為本發明之第三實施態樣。其中每一該表層30之表面皆形成該非平面301。施工者可將該多層吸音減震墊100鋪設於樓地板，並於其上進行水泥灌漿，則接觸樓地板之該非平面301可餘留空隙達到預期之吸音效果，另一側接觸水泥之該非平面301則與水泥有較平面形式更大的接觸面積，藉此獲得更佳的水泥結合性。再請參照第4圖所示，為本發明之第四實施態樣。其整體結構與本發明第三實施態樣相仿，但該等非平面301互為錯落設置，即在圖示之橫軸方向上，每一該非平面301同時形成凹陷或凸出之起伏，而能使該多層吸音減震墊100具有不同之厚度，而能依不同需求設計其吸音減震程度。
綜上所述，本發明多層吸音減震墊100利用針軋方式將每一該表層30、每一該防水透濕層20、以及該緩衝層10相結合。每一該表層30可供水泥澆置，並在固化後與水泥穩固連接。每一該防水透濕層20可避免水份進入緩衝層10且同時具備透濕效果，可將多餘水份藉由擴散或對流方式排乾。該緩衝層10、每一該防水透濕層20以及每一該表層30藉由針軋結合為一體，並透過預軋纖維31彼此纏結而能避免工件分離、變形等問題。
以上已詳細說明本發明之內容，惟以上所述者，僅為本發明之較佳實施例而已，當不能以此限定本發明實施之範圍，即凡依本發明申請專利範圍所作之均等變化與修飾，皆應仍屬本發明之專利涵蓋範圍內。
