2005版“建筑业十项新技术”之八
建筑防水新技术
8.1 新型防水卷材应用技术
新型防水卷材是具有特定的长度、宽度和厚度的柔性防水材料。根据防水
卷材的主要原料可分为两大类：高聚物改性沥青类防水卷材、合成高分子
防水卷材。
8.1.1 高聚物改性沥青防水卷材应用技术
(1) 主要技术内容
高聚物改性沥青防水卷材，是以高聚物改性沥青为涂盖物以聚酯胎、玻纤
胎等为胎体，表面覆以聚乙烯膜、铝箔膜、砂粒或页岩片的防水卷材。
主要品种：1）SBS（弹性体）改性沥青防水卷材：以SBS 改性沥青类防水
卷材为主的弹性体改性沥青防水卷材还包括SBR、EPDM 等弹性体改性沥青
防水卷材等；2）APP（塑性体）改性沥青防水卷材：以APP 改性沥青类防
水卷材为主的塑性体改性沥青防水卷材还包括APAO、或APO 改性沥青防水
卷材等。SBS 改性沥青防水卷材的低温性能较好可达25℃， 可在温度较
低条件下施工，耐高温性能为90℃～100℃。APP 改性沥青防水卷材耐高
温的能力强可达110℃～130℃不流淌，低温性能可在﹣15℃～﹣10℃。适
用于温度较高环境及外露使用。高聚物改性沥青防水卷材的胎体性能对应
用效果影响极大；应首选强度和延伸率均好的长纤维聚酯胎或无碱、低碱
玻纤胎高聚物改性沥青防水卷材。高聚物改性沥青防水卷材应重点推广达
到标准中Ⅱ型指标要求的SBS（APP）改性沥青防水卷材产品。重点推广厚
度达到4mm、3mm 以上规格的产品和热熔施工法，一般可根据设防要求分
别采用双层(4mm+4mm；4mm+3mm；3mm+3mm)或单层(4mm)作法。
(2) 主要技术指标
高聚物改性沥青防水卷材执行《弹性体改性沥青防水卷材》GB18242-2000
和《塑性体改性沥青防水卷材》GB18243-2000 等标准的规定。
(3) 适用范围
SBS（APP）改性沥青防水卷材适用于工业与民用建筑的屋面与地下1～4
级防水设防。
(4) 已应用的典型工程
SBS（APP）改性沥青防水卷材已在国内外广泛应用于工业与民用建筑的屋
面与地下防水工程。目前年用量达6000～7000 万m2。典型工程如：首都
机场2、3 号航站楼地下防水、中关村西区、北京新闻中心、

Waterproof technology
8.1 Application of the new waterproofing membrane technology
New waterproof membrane is a specific length, width and thickness of the flexible waterproof material. Under water
The main raw material sheet can be divided into two main categories: polymer modified asphalt waterproofing membrane type, synthetic polymer
Waterproofing membrane.
8.1.1 Application of polymer modified bitumen membrane technology
(1) The main content of
Polymer modified bitumen membrane, is coated with polymer modified asphalt material for polyester fiber, glass fiber
Tire carcass such as the surface covered with polyethylene film, aluminum foil film, sand or shale film waterproofing membrane.
Varieties: 1) SBS (elastic) modified asphalt waterproofing membrane: the SBS modified asphalt waterproof class
Membrane-based elastomer modified asphalt waterproofing membrane include SBR, EPDM elastomer modified asphalt, etc.
Waterproofing membrane, etc.; 2) APP (plastic body) modified asphalt waterproofing membrane: the class of anti-APP modified asphalt
Water-based plastic membrane modified bitumen waterproofing membrane also APAO, or APO modified bitumen
Coil. SBS modified bitumen membrane good low temperature performance of up to 25 ℃, the temperature can be more
Construction of low condition, high temperature performance is 90 ℃ ~ 100 ℃. APP modified bitumen membrane with high resistance
Temperature capability up to 110 ℃ ~ 130 ℃ does not flow, low temperature can be -15 ℃ ~ -10 ℃. Proper
For high temperature environments and exposure to use. Polymer modified bitumen membrane properties of the corresponding matrix
Effect of great use; should be a good choice for strength and elongation of long fiber polyester tire or alkali, low-alkali
Fiberglass tire polymer modified bitumen membrane. Polymer modified asphalt waterproofing membrane over key promotion
To the standard indicators of the requirements of type Ⅱ SBS (APP) modified asphalt waterproofing membrane products. Focus on promotion of thick
Degree to 4mm, 3mm or more specifications of products and hot-melt construction method, and can be divided according to the requirements for fortification
Do not use double-layer (4mm +4 mm; 4mm +3 mm; 3mm +3 mm) or single-layer (4mm) approach.
(2) Main technical index
The implementation of polymer modified asphalt waterproofing membrane "elastomer modified asphalt waterproofing membrane" GB18242-2000
And "plastic modified bitumen waterproofing membrane" GB18243-2000 and other standards.
(3) Scope
