環(huan)氧樹(shu)脂(zhi)稀(xi)釋(shi)劑(ji)是配(pei)合基礎樹(shu)脂(zhi)混合使用，它(ta)不但不會(hui)降(jiang)低(di)環(huan)氧樹(shu)脂(zhi)的(de)(de)交聯密度，不會(hui)降(jiang)低(di)固(gu)化后(hou)的(de)(de)硬度，而(er)且還可(ke)以降(jiang)低(di)固(gu)化體系粘(zhan)(zhan)度，增加流動性(xing)，延長環(huan)氧樹(shu)脂(zhi)地坪(ping)漆(qi)的(de)(de)使用壽命(ming)，便于大面積施(shi)工；改(gai)善(shan)了地坪(ping)漆(qi)操作(zuo)性(xing)的(de)(de)同時，又不影(ying)響固(gu)化物的(de)(de)基本(ben)性(xing)能。方(fang)便用于澆(jiao)鑄、灌注(zhu)、粘(zhan)(zhan)接(jie)、密封、浸漬等方(fang)面之應用。

環(huan)氧(yang)樹(shu)脂(zhi)(zhi)(zhi)稀(xi)釋(shi)劑分兩種(zhong)：一種(zhong)是(shi)(shi)非(fei)活(huo)性(xing)(xing)稀(xi)釋(shi)劑，也(ye)就(jiu)是(shi)(shi)常用的(de)一些(xie)溶(rong)劑；一種(zhong)是(shi)(shi)活(huo)性(xing)(xing)稀(xi)釋(shi)劑，加在樹(shu)脂(zhi)(zhi)(zhi)中(zhong)(zhong)(zhong)可(ke)以(yi)稀(xi)釋(shi)樹(shu)脂(zhi)(zhi)(zhi)，并能參(can)與樹(shu)脂(zhi)(zhi)(zhi)的(de)固(gu)(gu)化(hua)(hua)，所謂的(de)無(wu)溶(rong)劑漆就(jiu)是(shi)(shi)用活(huo)性(xing)(xing)稀(xi)釋(shi)劑稀(xi)釋(shi)的(de)。非(fei)活(huo)性(xing)(xing)稀(xi)釋(shi)劑不(bu)含有環(huan)氧(yang)基團(tuan)，不(bu)能參(can)與固(gu)(gu)化(hua)(hua)反(fan)應(ying)。非(fei)活(huo)性(xing)(xing)稀(xi)釋(shi)劑加入(ru)環(huan)氧(yang)樹(shu)脂(zhi)(zhi)(zhi)中(zhong)(zhong)(zhong)一般都會(hui)(hui)降低固(gu)(gu)化(hua)(hua)交聯(lian)密度，環(huan)氧(yang)樹(shu)脂(zhi)(zhi)(zhi)固(gu)(gu)化(hua)(hua)時間(jian)會(hui)(hui)減(jian)(jian)慢(man)，耐溫(wen)(wen)性(xing)(xing)、固(gu)(gu)化(hua)(hua)后(hou)強度都會(hui)(hui)降低。活(huo)性(xing)(xing)稀(xi)釋(shi)劑中(zhong)(zhong)(zhong)間(jian)含有環(huan)氧(yang)基團(tuan)，可(ke)以(yi)參(can)與固(gu)(gu)化(hua)(hua)反(fan)應(ying)并形(xing)成三維(wei)交聯(lian)結構。加入(ru)后(hou)都會(hui)(hui)減(jian)(jian)慢(man)環(huan)氧(yang)樹(shu)脂(zhi)(zhi)(zhi)的(de)固(gu)(gu)化(hua)(hua)時間(jian)，降低耐溫(wen)(wen)性(xing)(xing)和固(gu)(gu)化(hua)(hua)后(hou)強度。但(dan)也(ye)有些(xie)活(huo)性(xing)(xing)稀(xi)釋(shi)劑加入(ru)環(huan)氧(yang)樹(shu)脂(zhi)(zhi)(zhi)當中(zhong)(zhong)(zhong)可(ke)以(yi)提高固(gu)(gu)化(hua)(hua)后(hou)強度和耐溫(wen)(wen)性(xing)(xing)。

總之，我(wo)(wo)們在(zai)選(xuan)擇(ze)(ze)環氧(yang)樹(shu)脂與固化劑(ji)(ji)體系(xi)(xi)中，如何進行(xing)選(xuan)擇(ze)(ze)適(shi)合的稀釋(shi)劑(ji)(ji)，我(wo)(wo)們一般會從氣味、體系(xi)(xi)硬度(du)、成本(ben)、稀釋(shi)效果、體系(xi)(xi)耐(nai)溫(wen)等性能方面進行(xing)選(xuan)擇(ze)(ze)不同的稀釋(shi)劑(ji)(ji)。
