Description

200900234 九、發明說明: [相關申請案之交互參照] 本專利申請案主張於2007年2月12日提出申請之美 國臨時專利申請案第60/889,487號的優先權,該案之人部 揭示内容併入本案作為參考。 ° 【發明所屬之技術領域】 本發明係關於耐水黏性物及製備該物的方法。 【先前技術】 黏性物(例如石膏板及水泥板)係利用於各種應用中, 其中有些需要某種程度的財水性。在高渥度的情形之下, 或是曝露在室外,傳統的面覆紙的黏性物(paper_faad cementitious article)並非總是表現良好。因此,對於此類 應用來說,通常期望使用塗有以玻璃或聚合物為基材的纖 維墊來代替紙。而在黏性物裡使用增進該核心材料本身耐 水性的添加物亦有優點。 例如石貧板及水泥板之黏性物的製程,典型地涉及將 黏性漿體沉積在第一覆面材料(facing material)之上,且以 同樣類型之第二覆面材料覆蓋潮濕的黏性漿體,以使該黏 性衆體夹在兩個覆面材料之間。之後,可藉由乾燥方式將 過多的水分從㈣體移除。在最終乾燥之前可使該黏性裝 體硬化以產生固體物。 …因此,黏性物的製程通常需要具有充分浸透性的覆面 材料’以使過多的水分可在乾燥製程中自該黏性漿體内移 除°舉例而言’ it常使用非編織的玻璃纖維塾作為覆面材 5 94225R01 200900234 料’而纖維間的㈣則提供浸透性。然而,因沉積於纖唯 塾覆面材料上的黏性浆體傾向於渗透該纖維塾而導致黏性 聚體堆積(buHd-up)在形成接(f〇ming 以及裝配線 ㈨semMy line)上’故具纖維之覆面材料的浸透性使得製程 更加困難。該黏性漿體堆積必須定期移除。增加該黏性浆 體的黏性雖可減少黏性漿體滲透纖維塾覆面材料的量,但 對於現存的工廠生產製程來說,由於必須改變例如混合、 广設定、乾燥或硬化特性,故所需的較高黏性並非總是最佳 的使用選擇。 再者,由於纖維墊t面材才斗使水能滲透該纖維墊,而 且於使用期間又會接觸黏性核心,故纖維塾覆面材料的浸 透性亦會降低黏性物的耐水性。為了減輕此問題,有時會 應用疏水樹脂(hydrophobicresin)的外部塗層。然而,一般 便需要採甩額外的後製步驟,此將增加成本與不便。 另一個方法是藉由在黏性漿體中包含疏水添加物,以 (進一步增加黏性核心的耐水性。用於此目的之較佳添加物 為矽氧烷油(siloxane oil)。然而,採用此添加物的方法需 要於該些方法的實施與效用上加以改進。 而 因此’對於新的耐水黏性物以及製備此物的方法仍有 玲求。 【發明内容】 於一個態樣中,本發明提供一種面覆纖維墊的黏性 物,包括(a)黏性核心,以及(b)第一纖維墊,包栝聚合物或 礦物纖維和位於至少一個表面上之疏水加工件 6 94225如1

於又-態樣中,本發明提供一種製備耐水黏性物 (water-resistant cementitious article)^ , 於水中包括約4 wt.%(重量%)至約8 wt%石夕氧烧水性:石夕 氧烷分散液(aqueous siloxane dispersi〇n),(b)將該矽氧烷 =散液與黏性混合物結合,以提供黏性漿體,⑷將該黏: 漿體沉積在基板上,以及(d)使該黏性漿體硬化,以二 供黏性物。

熱或防火纖維於該纖維墊中。 第一纖維墊可為編織或非編織的;然而,較隹為非編 織墊。非'編織塾包括藉由黏結劑(binder)黏結在一起的纖 維。該黏結劑可為任何典型地使用於纖維墊工業的黏結 劑。適當的黏結劑包含(而不限定於)尿素曱醛(urea \ ' formaldehyde)、二聚亂胺曱给(melamine formaldehyde)、 硬脂酸鹽二聚氧胺曱輕(stearated melamine
