Description

一种亲水型双阻份高分子防水涂料
技术领域
本发明涉及一种建筑材料，尤其指一种防水涂料。
背景技术
目前，市场上的防水材料主要是聚氨酯类防水涂料，这类材料一般是由聚氨脂与煤焦油作为原材料制成，它所挥发的焦油气毒性大，且不容易清除，因此于2000年在中国被禁止使用。而尚在销售的聚氨脂防水涂料，是用沥青代替煤焦油作为原料，且含有易挥发的溶剂类成份，如二甲苯等，甚至，在使用这种涂料时，一般采用含有甲苯、二甲苯等有机溶剂来稀释才能调到适于施工的稀稠度，因而也含有毒性。 因苯类溶剂污染了环境，损害了人体健康，甚至在一些通风条件不好的环境中施工，会直接威胁施工人员的生命健康，且苯类溶剂易燃易爆，给消防安全构成极大的威胁。
因此，有必要设计一种新的防水涂料，以解决上述问题。
发明内容
本发明的创作目的在于提供一种通过采用催化剂将油熔性的油料乳化呈水乳性的物质，使其可直接用水稀释的亲水型双阻份高分子防水涂料。
为了达到上述目的，本发明采用如下技术方案：一种亲水双阻份高分子防水涂料，其包括甲组份和乙组份，所述甲组份中各组分含量以重量百分比计算为：聚醚多元醇70%， 酒石酸9.1%，二辛脂3.6%以及甲苯二异氰酸酯17.3%；所述乙组份中各组分含量以重量百分比计算为：70#沥青32.5%，二辛脂2.2%，古马隆树脂20.6%，碳黑0.75%，陶土4.4%，氢氧化钙1.9%，325#水泥粉13%，滑石粉20.6%，催化剂1.3%，水2.5%，以及固化剂0.25%。
进一步，所述催化剂为二月桂酸二丁基锡。
本发明还提供亲水双阻份高分子防水涂料的制备方法，包括以下步骤：S1：制备甲组份：首先将70%的聚醚多元醇，9.1%的酒石酸和3.6%的二辛脂加入反应釜中加热搅拌，当温度升至60摄氏度后，停止升温；然后加入17.3%的甲苯二异氰酸酯搅拌，使其自然反应约20分钟后，开始升温至80摄氏度，维持温度80摄氏度开始计时，恒温保持90分钟后，降温，冷却后即得甲组份；S2：制备乙组份：首先将32.5%的70#沥青和2.2%的二辛脂加入反应釜中升温至100摄氏度，边搅拌边升温，反应120分钟，使其充分脱水后，停止升温；然后按顺序往反应釜中加入0.75%的碳黑，4.4%的陶土，边搅拌边加入，搅拌20分钟后，再按顺序加入1.9%的氢氧化钙，13%的325#水泥粉，搅拌30分钟后加入1.3%的催化剂，再搅拌30分钟；最后加人2.5%的水和9%的固化剂搅拌50分钟后，即得乙组份；其中， 步骤和步骤S2不分先后顺序；S3：将S1步骤中的甲组份和S2步骤中的乙组份按重量比为1:2的比例混合，搅拌均匀后即得目标产品。
进一步，所述催化剂为二月桂酸二丁基锡。
本发明的亲水双阻份高分子防水涂料，通过采用催化剂将油熔性的油料乳化呈水乳性的物质，使其可直接用水稀释，相较于传统的聚氨脂防水涂料，生产中无需加入含有甲苯、二甲苯等有机溶剂来稀释，从而避免污染环境，损害人体健康，使用安全且节约成本。
【具体实施方式】
下面的实施例可以帮助本领域的技术人员更全面的理解本发明，但不可以以任何方式限 制本发明。
本发明的亲水型双阻份高分子防水涂料包括甲组份和乙组份。所述甲组份包括聚醚多元
醇， 酒石酸，二辛脂以及甲苯二异氰酸酯，各组分含量以重量百分比计算分别为70%，9.1%，3.6%，17.3%；所述乙组份包括70#沥青，二辛脂，古马隆树脂，碳黑，陶土，氢氧化钙，325#水泥粉，滑石粉，催化剂，水，以及固化剂，各组分含量以重量百分比计算分别为：32.5%， 2.2%，20.6%，0.75%， 4.4%，1.9%，13%，20.6%，1.3%，2.5%，以及0.25%。所述催化剂为二月桂酸二丁基锡，通过所述催化剂将组份里面的油溶性物质进行乳化变成水溶性物质，从而使得所述亲水型双阻份高分子防水涂料可直接用水进行稀释，无需加入含有甲苯、二甲苯等有机溶剂来稀释，从而避免污染环境，损害人体健康，使用安全且节约成本。
本发明还提供一种亲水型双阻份高分子防水涂料的制备方法，包括以下步骤：
S1：制备甲组份：首先将70%的聚醚多元醇，9.1%的酒石酸和3.6%的二辛脂加入反应釜中加热搅拌，当温度升至60摄氏度后，停止升温；然后加入17.3%的甲苯二异氰酸酯搅拌，使其自然反应约20分钟后，开始升温至80摄氏度，维持温度80摄氏度开始计时，恒温保持90分钟后，降温，冷却后即得甲组份。
在步骤S1之后进行步骤S2：制备乙组份：首先将32.5%的70#沥青和2.2%的二辛脂加入反应釜中升温至100摄氏度，边搅拌边升温，反应120分钟，使其充分脱水后，停止升温；然后按顺序往反应釜中加入0.75%的碳黑，4.4%的陶土，边搅拌边加入，搅拌20分钟后，再按顺序加入1.9%的氢氧化钙，13%的325#水泥粉，搅拌30分钟后加入1.3%的催化剂，再搅拌30分钟；最后加人2.5%的水和9%的固化剂搅拌50分钟后，即得乙组份。
接着进行步骤S3：将S1步骤中的甲组份和S2步骤中的乙组份按重量比为1:2的比例混合，搅拌均匀后即得目标产品。另，步骤S1和步骤S2可以不分先后顺序，即是：可先进行步骤S2再进行步骤S1，也可以步骤S1和步骤S2同时进行，并不以此为限。
综上所述，本发明的亲水型双阻份高分子防水涂料采用二月桂酸二丁基锡为催化剂，通过所述催化剂将组份里面的油溶性物质进行乳化变成水溶性物质，从而使得所述亲水型双阻份高分子防水涂料可直接用水进行稀释，无需加入含有甲苯、二甲苯等有机溶剂来稀释，从而避免污染环境，损害人体健康，使用安全且节约成本。
