Abstract
一種膠帶，其包括基底、形成於該基底上之膠層及分散於該膠層表面之膠粒，該膠層之黏著力大於該膠粒之黏著力。
Description
本發明涉及一種膠帶。
消費型電子產品中目前一般採用黏膠將二工件黏結在一起。一方面，黏膠需具有較好之黏結性以穩固黏結零件；另一方面，重工時，黏膠又需具有較好之易撕離性；即黏膠既需具有較好之黏結性又需具有較好之易撕離性。然，習知之黏膠很難二者兼顧。
鑒於上述狀況，有必要提供一種較易撕離且黏結性較佳之膠帶。
一種膠帶，其包括基底、形成於該基底上之膠層及分散於該膠層表面之膠粒，該膠層之黏著力大於該膠粒之黏著力。
一方面，由於膠粒之黏著力較低，在貼合初期，較易撕離膠帶；另一方面，由於膠層之黏著力較高，待膠層滲透後，膠帶之黏結力較高，從而可保證膠帶之黏結性較好。
請參閱圖1，本發明實施方式之膠帶100包括基底10、形成於基底10上之膠層20及分散於膠層20表面上之膠粒30，膠層20之黏著力大於膠粒30之黏著力。基底10可為塑膠薄膜。可理解，基底10不限於塑膠薄膜，也可為其他用於膠帶之基底，如牛皮紙、美紋紙等。
在本實施方式中，膠層20之黏著力大於或等於10牛頓每英寸（N/in）；膠粒30之黏著力範圍大致為1-10N/in。膠粒30在膠層20表面之分佈密度可調節。在本實施方式中，膠粒30採用噴灑方式均勻分佈於膠層20表面上，膠粒30之直徑大致為0.1-100微米（μm），膠粒30之分佈密度大致為10%-80%。
使用時，膠粒30先接觸待黏結工件200，此時，膠帶100與待黏結工件200間之黏結力較低，較易將膠帶100從待黏結工件200表面撕離（請參閱圖1），以方便重工；然後，對膠帶100施加一定壓力或/和加熱，使膠層20經預設時間後通過膠粒30間之縫隙滲透至待黏結工件200表面，從而使膠帶100與待黏結工件200間之黏結力提高，膠帶100與待黏結工件200緊密貼合（請參閱圖2）。膠層20未滲透至待黏結工件200表面，膠帶100與黏結工件200完全緊密貼合前之預設時間即為重工時間。
根據不同之使用需求，可藉由調節施加壓力、加熱溫度、膠粒30之粒徑、黏著力及分佈密度、及膠層20之黏著力來調節重工時間、初始黏著力及最終黏著力，以適應不同之使用需求。
為詳細說明加熱溫度、膠粒30之粒徑、黏著力及分佈密度、及膠層20之黏著力對重工時間、初始黏著力及最終黏著力之影響，下文表1中列舉若干具體實施例進行說明，該若干實施例均未對膠帶100施加額外壓力。
表1 實施例1-9性能測試結果
本發明實施方式之膠帶100，一方面，由於膠粒30之黏著力較低，在貼合初期，較易撕離；另一方面，由於膠層20之黏著力較高，待膠層20滲透後，膠帶100之黏結力較高，從而可保證膠帶100之黏結性較好。同時，可藉由可藉由調節施加壓力、加熱溫度、膠粒30之粒徑、黏著力及分佈密度、及膠層20之黏著力來調節重工時間、初始黏著力及最終黏著力，以適應不同之使用需求
綜上所述，本發明確已符合發明專利之要件，遂依法提出專利申請。惟，以上所述者僅為本發明之較佳實施方式，自不能以此限制本案之申請專利範圍。舉凡熟悉本案技藝之人士爰依本發明之精神所作之等效修飾或變化，皆應涵蓋於以下申請專利範圍內。
100．．．膠帶
10．．．基底
20．．．膠層
30．．．膠粒
