Classification and performance of waterproofing membrane

防水卷材，由沥青、橡胶或其他有机材料制成的成卷防水材料，俗称油毡或油毛毡。它具有良好的防水性和较好的柔韧性。

Waterproof membrane, made of asphalt, rubber or other organic materials into rolls of waterproof materials, commonly known as felt or felt. It has good water repellency and good flexibility.

主要是用于建筑墙体、屋面、以及隧道、公路、垃圾填埋场等处，起到抵御外界雨水、地下水渗漏的一种可卷曲成卷状的柔性建材产品，作为工程基础与建筑物之间无渗漏连接，是整个工程防水的第一道屏障，对整个工程起着至关重要的作用。产品主要有沥青防水卷材和高分子防水卷材。

It is mainly used in building walls, roofs, tunnels, highways, landfills and other places, to resist external rainwater, groundwater leakage into a coiled flexible building materials products, as a non-seepage connection between the project foundation and the building, is the whole project waterproof first barrier, the entire project plays a role Crucial role. The main products are asphalt waterproofing membrane and polymer waterproofing membrane.

分类

classification

将沥青类或高分子类防水材料浸渍在胎体上，制作成的防水材料产品，以卷材形式提供，称为防水卷材。根据主要组成材料不同，分为沥青防水卷材、高聚物改性沥青防水卷材和合成高分子防水卷材;根据胎体的不同分为无胎体卷材、纸胎卷材、玻璃纤维胎卷材、玻璃布胎卷材和聚乙烯胎卷材。

The waterproof material products made by impregnating asphalt or polymer waterproof materials on the matrix are provided in the form of rolls, which are called waterproof rolls. According to the main composition of different materials, divided into asphalt waterproof roll, polymer modified asphalt waterproof roll and synthetic polymer waterproof roll; according to the different matrix is divided into non-matrix roll, paper tire roll, glass fiber tire, glass cloth tire roll and polyethylene tire.

防水卷材要求有良好的耐水性，对温度变化的稳定性(高温下不流淌、不起泡、不淆动;低温下不脆裂)，一定的机械强度、延伸性和抗断裂性，要有一定的柔韧性和抗老化性等。

Waterproof rolls require good water resistance, stability to temperature changes (no flow at high temperatures, no foaming, no confusion; no brittle cracking at low temperatures), certain mechanical strength, elongation and fracture resistance, flexibility and aging resistance.

防水卷材是一种可卷曲的片状防水材料。是建筑工程防水材料中的重要品种之一。

Waterproofing membrane is a kind of curly sheet waterproof material. It is one of the important varieties of waterproof materials in building engineering.

根据其主要防水组成材料可分为沥青防水材料、高聚物改性防水卷材和合成高分子防水卷材（SBC120聚乙烯丙纶复合卷材）三大类。有PVC、EVA、PE、ECB等多种防水卷材

According to its main waterproofing components can be divided into asphalt waterproofing materials, polymer modified waterproofing membrane and synthetic polymer waterproofing membrane (SBC120 polyethylene polypropylene fibershiyanjit.89ix.com dipings.89ix.com falafa.89ix.com fengguanf.89ix.com jiareqid.89ix.com waiqiangz.89ix.com composite membrane) three categories. There are PVC, EVA, PE, ECB and other waterproofing membrane.

沥青防水卷材是在基胎（如原纸、纤维织物）上浸涂沥青后，再在表面撒布粉状或片状的隔离材料而制成的可卷曲片状防水材料。

Asphalt waterproof roll is a kind of curly sheet waterproof material which is made by dipping asphalt on the base tire (such as base paper, fiber fabric) and then spreading powder or sheet-like isolating material on the surface.

性能

performance

1.耐水性

1. water resistance

耐水性是指在水的作用下和被水浸润后其性能基本不变，在压力水作用下具有不透水性，常用不透水性、吸水性等指标表示。

Water resistance means that under the action of water and after being soaked by water, its performance is basically unchanged. Under the action of pressure water, it is impermeable. It is often expressed by water permeability, water absorption and other indicators.

2.温度稳定性

2. temperature stability

温度稳定性指在高温下不流淌、不起泡、不滑动，低温下不脆裂的性能，即在一定温度变化下保持原有性能的能力。常用耐热度、耐热性等指标表示。

Temperature stability refers to the performance of non-flowing, non-foaming, non-sliding at high temperature, non-brittle cracking at low temperature, that is, the ability to maintain the original performance under a certain temperature change. Commonly used heat resistance, heat resistance and other indicators.

3.机械强度、延伸性和抗断裂性

3. mechanical strength, elongation and fracture resistance

它指防水卷材承受一定荷载、应力或在一定变形的条件下不断裂的性能。常用拉力、拉伸强度和断裂伸长率等指标表示。

It means that waterproofing membrane bears no fracture under certain load, stress or deformation conditions. Commonly used indicators such as tensile strength, tensile strength and elongation at break are indicated.

4.柔韧性

4. flexibility

柔韧性指在低温条件下保持柔韧性的性能。它对保证易于施工、不脆裂十分重要。常用柔度、低温弯折性等指标表示。

Flexibility refers to the flexibility to maintain flexibility at low temperatures. It is very important to ensure easy construction and no crack. Commonly used flexibility, low temperature bending and other indicators.

5.大气稳定性
