Abstract

本发明公开了一种防水剂，由以下成份按照一定重量份配制而成：其特征在于，由以下组份按照一定重量份配制而成：改性丙烯酸酯乳液20‑50份；EVA乳液30‑100份；氯丁乳胶20‑30份；分散剂1‑3份；碱金属硅酸盐2‑3份；催化剂1‑3份；助剂0.2‑0.9份。本发明为无机防水剂型防水剂，含有催化剂和改性丙烯酸酯乳液、EVA乳液、氯丁乳胶复合的水基溶液，其最大的特点是可以渗透到内部，并和碱性物质起化学反应，在水泥内部生成乳胶体，填充堵塞水泥内的毛细管而起到作用，形成致密的永久防水层。可防止盐、酸雨和大气中二氧化碳、二氧化硫等气体对水泥混凝土表面的侵蚀，防止碳化，可提高混凝土的强度。

Description

一种防水剂
技术领域
本发明涉及涂料领域，具体涉及一种防水剂。
背景技术
混凝土在硬化后，一般情况下其内部存在着空隙，因此会透过水分，即混凝土存在着渗透性，如果使用防水剂则可大大减少这种空隙，使混凝土的密实性得到提高，从而提高混凝土的抗渗性。
防水剂可以用作外墙防水，较方便有效。防水剂可以直接在基层上涂刷，也可以掺和在水泥砂浆中形成防水砂浆使用。传统的防水剂一般是双组分环氧防水剂，由于可与环氧涂料掺和，因此可以作为环氧涂料的防水剂，但如果转用丙烯酸类涂料，则难以使用传统的双组分环氧防水剂，应用范围不高。
发明内容
针对现有技术的不足，本发明提供一种可适用于丙烯酸类涂料的防水剂。
一种防水剂，其特征在于，由以下组份按照一定重量份配制而成：
改性丙烯酸酯乳液 20-50份
EVA乳液 30-100份
氯丁乳胶 20-30份
分散剂 1-3份
碱金属硅酸盐 2-3份
催化剂 1-3份
助剂 0.2-0.9份。
作为优选的技术方案之一，其特征在于，所述的改性丙烯酸酯乳液为有机硅改性丙烯酸酯乳液。
作为优选的技术方案之一，其特征在于，所述的催化剂为单丁基锡。
作为优选的技术方案之一，其特征在于，所述的助剂为甲基硅醇钠和高沸硅醇钠的混合物。
本发明的有益效果是：本发明为无机防水剂型防水剂，含有催化剂和改性丙烯酸酯乳液、EVA乳液、氯丁乳胶复合的水基溶液，其最大的特点是可以渗透到内部，并和碱性物质起化学反应，在水泥内部生成乳胶体，填充堵塞水泥内的毛细管而起到作用，形成致密的永久防水层。可防止盐、酸雨和大气中二氧化碳、二氧化硫等气体对水泥混凝土表面的侵蚀，防止碳化，可提高混凝土的强度。本发明可应用于丙烯酸类涂料的涂料上。
