背景：
随着人们对生活品质的更高追求，环保型新材料的需求越来越大，及国家对环保要求越来越严格，“油”改“水”必将成为未来的发展趋势，水性丙烯酸乳液的技术及制备方法也要求越来越高。
用途：
丙烯酸乳液是用于建筑防水、水性油墨、拼板胶等。被广泛应用于多个领域如下：
1. 各种高中低档内外墙乳胶漆。
2. 外墙乳胶漆、真石漆、岩片漆、质感漆。
3. 用于丝织物、皮革涂饰剂。
4. 相片打印纸张的涂饰剂、纸张的处理剂。
5. 对木材的油脂、单宁酸封闭性能好，用于木材、木板、地板透明封闭底漆。
6. 电沉积涂料，用于金属水性漆、塑料水性漆的粘结剂。
7. 沥青防水改性剂。
8. 用于高分子材料抗静电剂、污水的絮凝剂、石油无固相钻井添加剂。
一、丙烯酸乳液分类：
1）按产品的用途分类可分为:内墙用乳液、外墙用乳液、弹性乳液、防水乳液、封闭乳液等。
2）按产品的组成可以分为:纯丙乳液、硅丙乳液、苯丙乳液、醋丙乳液等。
二、丙烯酸乳液特性：
无毒、无刺激，对人体无害，符合环保要求，非成膜高光树脂，具有优异的光泽与透明性,抗粘连性能好。
水性丙烯酸乳液工艺介绍：
制备水性丙烯酸乳液：将原料中包括丙烯酸硬单体、丙烯酸软单体和丙烯酸功能单体的全部丙烯酸单体、乳化剂、水加入到金宗乳化釜中，乳化。得到不分层的乳化液；然后在金宗聚合反应釜中加入剩余的水、剩余的乳化剂、缓冲剂，升温，投入乳化液，加入引发剂反应，滴加剩余的上述制得的所述乳化液与剩余的引发剂，设定时间滴完；接着将金宗聚合反应釜升温至一定温度保温反应，降温至一定温度加入pH调节剂调节反应体系的PH值为6～7之间．即制得水性丙烯酸乳液。

Tip: If the failing expression is known to be legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
