Cracking-resistant cement-base waterproof coating

一种抗裂水泥基防水涂料

Abstract

The invention discloses a cracking-resistant cement-base waterproof coating which comprises the following components in parts by weight: 46-47 parts of ordinary portland cement, 4-5 parts of silica fume, 37-39 parts of quartz sand, 3-5 parts of quartz powder, 0.02-0.05 parts of cellulose ether, 0.1-0.3 parts of flow modifier, 0.05-0.08 parts of calcium formate, 1-1.2 parts of water repellent, 8-10 parts of redispersible polymer powder, 0.38 parts of filler, and 35-40 parts of water. According to the cracking-resistant cement-base waterproof coating, contents of cement and sand in the traditional cement coating and a proportion of the redispersible polymer powder are changed, and the cracking resistance is improved. The cracking-resistant cement-base waterproof coating is combined with rigidity and flexibility, does not crack, is strong in adhesive force, good in waterproof effect, collision-resistant, and long in service life, and can be constructed on a humid base layer; the base layer is not required to be levelled; no protective layer is required to be made on a waterproof layer; the construction period is shortened; the comprehensive construction cost is lowered; and the cracking-resistant cement-base waterproof coating has the characteristics that the cracking-resistant cement-base waterproof coating is nontoxic, odorless, high- and low-temperature-resistant, green, and environment-friendly.
本发明公开了一种抗裂水泥基防水涂料,它由以下重量份的组分组成:普通硅酸盐水泥46~47份,硅灰4~5份,石英砂37~39份,石英粉3~5份,纤维素醚0.02~0.05份,流动改性剂0.1~0.3份,甲酸钙0.05~0.08份,憎水剂1~1.2份,可再分散胶粉8~10份,填料0.38份,水35~40份。本发明改变了传统水泥涂料中水泥、砂的含量以及可再分散性胶粉的配比,增加了抗开裂性能,本发明刚柔结合、不开裂,附着力强,防水效果好,耐碰撞,使用寿命长,可在潮湿基层上施工,基层无需找平,防水层上无需做保护层,缩短工期,减少综合造价,同时具有无毒、无味、耐高低温、绿色环保等特点。
