市场中有哪几类防水材料？

What kinds of waterproof materials are there in the market?

市场上的防水材料不下上百种，而真正与我们息息相关的材料也就三四种左右。就建材超市来讲主要有：①聚氨脂类②丙烯酸类③聚合物水泥类④水泥灰浆类。

There are more than 100 kinds of waterproof materials on the market, and there are about three or four kinds of materials that are closely related to us. As for building materials supermarkets, there are mainly: 1. Polyurethane, acrylic acid, polymer cement and cement mortar.

二、各类防水材料的性能对比如何？

Two. How is the performance comparison of all kinds of waterproof materials?

防水性能而言，最好的是聚合物高分子>聚氨脂类>丙烯酸类>水泥灰浆类。

For waterproofing performance, polymer polymers, polyurethane, acrylic and cement mortar are the best.

三、聚氨脂类防水涂料的特点是什么？

Three, what are the characteristics of polyurethane waterproof coatings?

聚氨脂类防水涂料有“液体橡胶”之称，是综合性能最好的防水涂料之一。具有涂膜坚韧、拉伸强度高、延伸性好、耐腐蚀、抗结构伸缩变形能力强等优点，并具有较长的使用寿命，但是有气味，黑色不环保等缺点。

Polyurethane waterproof coating is known as "liquid rubber", and it is one of the most comprehensive waterproof coatings. It has many advantages, such as tough film, high tensile strength, good extensibility, corrosion resistance, resistance to structural expansion and deformation, and has long service life, but it has some disadvantages, such as odor and black environmental protection.

四、丙烯酸防水涂料的主要特点是什么？

Four, what are the main characteristics of acrylic waterproof coating?

丙烯酸防水涂料是一种单组分、环保型的弹性防水涂料。它是以自交联纯丙乳液为基础，配合特殊改性剂、功能助剂和填料经过分散研麿而成。该类材料无毒、无害、不可燃，是绿色环保型产品。

Acrylic waterproof coating is a single component, environmental friendly elastic waterproof coating. It is a self crosslinking acrylic emulsion as the foundation, with a special modifier, functional additives and fillers dispersed by research and mo. This material is non-toxic, harmless and non flammable, and is a green and environment-friendly product.

它具有较好的延伸率和拉伸强度，纯丙烯酸耐老化性非常好，防水层的使用寿命也很长，而且施工方便，辊涂、刮涂均可施工。防水层形成接点的连续弹性膜，对结构复杂的异型部位施工尤为方便。由于其性能特点比较稳定，应用效果理想，价格适中，因此在家装防水中广泛应用，主要在大型工程中使用。

It has good extensibility and tensile strength. The aging resistance of pure acrylic acid is very good. The service life of the waterproof layer is very long, and the construction is convenient. The roll coating and the scraping coating can be constructed. The continuous elastic membrane formed by the waterproof layer forms the contact point, which is especially convenient for the construction of the complex irregular section. Because its performance characteristics are relatively stable, the application effect is ideal and the price is moderate, so it is widely used in home decoration waterproofing, mainly used in large-scale projects.
