1262844 A7 B7 五、發明説明(i ) 發明所屬之技術領域 (請先閱讀背面之注意事項再填寫本頁) 本發明係有關於一種膜接合方法,以此膜接合方法產 製之寬幅膜,及以此寬幅膜製成之農業用覆蓋材料。 先前技術 寬幅膜一般被使用爲農業用覆蓋材料。以工業規模產 製之諸如農業用氯乙烯膜(於下稱之爲農業用膜)的膜, 具有1至4m的寬度。因爲寬度問題,該種膜不足以做爲農 業用覆蓋材料。依此,經由接合這些膜而獲致的具有較大 寬度之膜,能使用爲農業用覆蓋材料。至於供這些膜用的 膜接合方法,採用在二膜之個別一末端部位處重疊並熱壓 重疊部位的接合方法。 即使在使用由諸如乙烯/四氟乙烯共聚物(於下稱之爲 ETFE)之氟樹脂製成的氟樹脂膜,或諸如聚乙烯或乙烯/乙 酸乙烯酯共聚物的聚烯烴構成之聚烯烴膜的情況中,膜不 具有親水性表面,相同於農業用膜之方式,採用於每一末 端部位處重疊並熱壓重疊部位爲二膜之接合方法。 經濟部智慧財產局員工消費合作社印製 但是,當使用不具有親水性表面的膜來建立農業用暖 房等時,由於在膜之內側處由於水凝結而造成水滴,膜之 透光性降低,或因爲水滴自膜落下在作物上,阻礙了作物 之成長。通常,經由導入親水性至被使用爲業業用覆蓋材 料的膜中,提供膜具有防滴落特性,可解決前述問題。 通常使用經由成型混合親水性劑之聚氯乙烯所形成的 膜來做爲農業用膜,以使呈現親水性效果。以含有親水性 本紙張尺度適用中國國家標準(CNS ) A4規格(210X297公釐) A7 1262844 B7 五、發明説明(2 ) 劑之膜,經由重疊膜的每一末端部份’並熱壓重璺部位以 使熔融粘合重疊部位,可輕易地形成寬幅膜。 在使用氟樹脂的情況中,不能採用混合親水性劑之方 法,因爲氟樹脂具有高模製溫度,會導致工業地可用之親 水性劑的分解。依此,採用將親水性物質塗層在氟樹脂膜 的一表面上之親水化方法。但是,在該種具有親水性表面 之氟樹脂膜當中,當膜被放置互相重疊且熱壓重疊部位以 粘合膜時,因爲親水性表面的存在,重疊部位不能被充份 地熔融粘合。 在解決前述問題的方法中,有一種方法係當膜表面遭 受親水性化時,遮蔽末端部位及其之附近部位,以形成未 施加親水性物質的部位;此一部位重疊一非親水性表面, 且熱壓重疊部位以供熔融粘合膜。 但是,因爲額外之遮蔽步驟,此一方法具有複雜之製 造程序,因而在形成寬幅膜時導致成本增加。 發明內容 本發明的一目的係提供一種方法,用以接合具有親水 性表面於其之單一表面處的膜(A)。 本發明的另一目的係提供一種經由重複前述方法至少 一次所獲致之寬幅膜,及經由使用寬幅膜形成農業用覆蓋 材料。 依據本發明,提供一種膜接合方法,包括裝設具有親 水性表面於其之單一表面處的二膜(A),對齊親水性表面 本紙張尺度適用中國國家標準(CNS ) A4規格(210X297公釐) -----------------、訂------ (請先閲讀背面之注意事項再填寫本頁) 經濟部智慧財產局員工消費合作社印製 1262844 _______ B7 五、發明説明(3 ) ’以使鄰接母一末端部位;覆蓋一膜(B)在膜(A)的非
