2005版“建筑業(yè)十項(xiàng)新技術(shù)”之八
建筑防水新技術(shù)
8.1 新型防水卷材應(yīng)用技術(shù)
新型防水卷材是具有特定的長度、寬度和厚度的柔性防水材料。根據(jù)防水
卷材的主要原料可分為兩大類：高聚物改性瀝青類防水卷材、合成高分子
防水卷材。
8.1.1 高聚物改性瀝青防水卷材應(yīng)用技術(shù)
(1) 主要技術(shù)內(nèi)容
高聚物改性瀝青防水卷材，是以高聚物改性瀝青為涂蓋物以聚酯胎、玻纖
胎等為胎體，表面覆以聚乙烯膜、鋁箔膜、砂粒或頁巖片的防水卷材。
主要品種：1）SBS（彈性體）改性瀝青防水卷材：以SBS 改性瀝青類防水
卷材為主的彈性體改性瀝青防水卷材還包括SBR、EPDM 等彈性體改性瀝青
防水卷材等；2）APP（塑性體）改性瀝青防水卷材：以APP 改性瀝青類防
水卷材為主的塑性體改性瀝青防水卷材還包括APAO、或APO 改性瀝青防水
卷材等。SBS 改性瀝青防水卷材的低溫性能較好可達(dá)25℃， 可在溫度較
低條件下施工，耐高溫性能為90℃～100℃。APP 改性瀝青防水卷材耐高
溫的能力強(qiáng)可達(dá)110℃～130℃不流淌，低溫性能可在﹣15℃～﹣10℃。適
用于溫度較高環(huán)境及外露使用。高聚物改性瀝青防水卷材的胎體性能對應(yīng)
用效果影響極大；應(yīng)首選強(qiáng)度和延伸率均好的長纖維聚酯胎或無堿、低堿
玻纖胎高聚物改性瀝青防水卷材。高聚物改性瀝青防水卷材應(yīng)重點(diǎn)推廣達(dá)
到標(biāo)準(zhǔn)中Ⅱ型指標(biāo)要求的SBS（APP）改性瀝青防水卷材產(chǎn)品。重點(diǎn)推廣厚
度達(dá)到4mm、3mm 以上規(guī)格的產(chǎn)品和熱熔施工法，一般可根據(jù)設(shè)防要求分
別采用雙層(4mm+4mm；4mm+3mm；3mm+3mm)或單層(4mm)作法。
(2) 主要技術(shù)指標(biāo)
高聚物改性瀝青防水卷材執(zhí)行《彈性體改性瀝青防水卷材》GB18242-2000
和《塑性體改性瀝青防水卷材》GB18243-2000 等標(biāo)準(zhǔn)的規(guī)定。
(3) 適用范圍
SBS（APP）改性瀝青防水卷材適用于工業(yè)與民用建筑的屋面與地下1～4
級防水設(shè)防。
(4) 已應(yīng)用的典型工程
SBS（APP）改性瀝青防水卷材已在國內(nèi)外廣泛應(yīng)用于工業(yè)與民用建筑的屋
面與地下防水工程。目前年用量達(dá)6000～7000 萬m2。典型工程如：首都
機(jī)場2、3 號航站樓地下防水、中關(guān)村西區(qū)、北京新聞中心、
2005 Edition "construction ten new technology" of 8
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
SBS (APP) modified asphalt waterproofing membrane for industrial and civil buildings in the roof and the ground 1 to 4
Waterproof fortification level.
(4) has been applied in a typical project
SBS (APP) modified asphalt waterproofing membrane has been widely used in domestic and foreign industrial and civil construction of the house
Surface and underground waterproofing. Current annual capacity of 6000 with 70 million m2. Typical projects such as: the capital
Airport Terminal 2,3 underground water, Zhongguancun District, Beijing News,
