天津市防水材料厂

In addition to directly affecting the comfort of residents' normal life and residence, roofing waterproofing will also affect the service life of buildings. The selection of waterproof material has a great influence on the quality and durability of the waterproof layer. The correct selection and rational use of waterproof material is one of the key factors for the success or failure of the housing roof. What waterproof materials should be chosen for residential roofs? Let's take a look together.

目前常用于住宅屋面的防水材料有以下几类：

At present, waterproofing materials commonly used for residential roofs are as follows:

1）防水卷材，包括改性沥青类和高分子类；

1) waterproofing membrane, including modified asphalt and polymer.

2）防水涂料，如聚氨酯防水涂料、水乳型沥青防水涂料等；

2) waterproof coating, such as polyurethane waterproof coating, water emulsion asphalt waterproof coating, etc.

3）瓦，如玻纤胎沥青瓦、烧结瓦和混凝土瓦等。

3) tiles, such as fiberglass tire asphalt tiles, sintered tiles and concrete tiles.

此外，为了更好地保证屋面防水效果，还会使用一些配套材料，如密封材料、高分子防水卷材胶粘剂和防水垫层等。

In addition, in order to better ensure the effect of roofing waterproof, some supporting materials, such as sealing material, polymer waterproof roll adhesive and waterproof cushion, will be used.

需要注意的是，住宅所处的地理环境不同、使用功能不同，其屋面选用的防水材料应有所区别。

It should be noted that the different geographical environment and function of residential buildings should be distinguished from the waterproof materials used for roofing.

1）应根据当地最高气温、最低气温、年温差、日温差条件等选择防水材料。在夏季温度高、冬天不太冷的地区，应选择耐热性能优异的防水材料（如APP改性沥青防水卷材），选购时可仔细查看材料的耐热性能指标；而在北方低温寒冷地区，应选用耐低温性能好的防水材料，可参考材料的低温柔性指标（如选择低温柔性可达-25℃的Ⅱ型SBS改性沥青防水卷材，其耐低温性能好）。

1) waterproofing materials should be selected according to local maximum temperature, minimum temperature, annual temperature difference and daily temperature difference. In the areas where the temperature is high in summer and the winter is not too cold in winter, the waterproof materials with excellent heat resistance (such as APP modified bitumen waterproof roll) are selected, and the heat resistance index of materials can be examined carefully when they are selected. In the North low temperature and cold areas, the waterproof material with good low temperature resistance should be selected, which can be used as reference to the low temperature flexibility index of the material. For example, the low temperature flexible -25 type SBS modified asphalt waterproofing membrane with low temperature flexibility can be selected.

2）一些允许人们上去看看夕阳、赏赏月的可上人屋面，通常会在防水层上贴铺地砖等，保护防水层，使防水层不直接暴露在外。这一类的屋面对防水材料耐紫外光老化的性能要求不高，可选用防水材料的范围较广，如改性沥青防水卷材、聚氯乙烯防水卷材和聚氨酯类防水涂料等。

2) some of the roofs that allow people to look at the setting sun and appreciate the moon, usually put a floor tile on the waterproof layer to protect the waterproof layer, so that the waterproof layer is not exposed directly. This kind of house is not high in resistance to ultraviolet aging of waterproof material, and the scope of waterproof material can be widely used, such as modified bitumen waterproof roll, PVC waterproof roll and polyurethane waterproof coating.
