2010 China's new type of roof waterproof material classification and application

With the development of society, in order to meet more consumer demand, building waterproofing now occupies a very important position in architectural design. It has always been one of the most complaints in construction projects. Leakage of floors, leakage of toilets, leakage of kitchens, leakage of external walls, and leakage of basements are considered to be “cancers” in buildings. However, some designers or construction units do not attach importance to waterproof design. They think that as long as the buildings are beautiful and the internal functions are reasonable, they are good buildings. However, if the waterproofing of the building is not done well, it will not only affect the overall quality of the project, but also increase the total project final accounts, causing unnecessary losses to the country and households, and will also have a great impact on the service life of the building. Waterproofing is an important division of a building. Level waterproofing technology is a science and technology that protects the structure of a building from water erosion and protects the interior space from water damage. So, how to completely cure this "cancer", which is related to the quality of the waterproof material. Therefore, we must pay attention to waterproof materials and construction processing.

With the changes of the times, the people's concept of building water resistance has changed from a single emphasis on a single economic cost concept to a functional concept, while also taking into account the construction cost and the service life of the waterproofing project. So, in this state of consciousness, why are there many tricks in the current waterproofing projects, but they still leak more often? What is the reason for this?

First of all, we must have a general understanding of the current situation of building waterproof materials in China and the types of building waterproof materials.

Since China began to apply asphalt linoleum membrane material in the 1950s, asphalt waterproof material has always been the leading product of China's building waterproof material, regardless of variety, quality or output have been rapidly developed. At present, the proportion of new waterproofing materials in China is still based on asphalt-based waterproof materials, which account for 80% of all waterproof materials. Polymer waterproofing membranes account for about 10%. Waterproof coatings and other waterproof materials account for 10%. about.

2010 Classification and Application of New Type Roofing Waterproof Materials in China

China's new building waterproof material is usually divided into five categories. Namely: waterproof membrane, waterproof coating, sealing material, rigid waterproof, and plugging and sealing material.

First, waterproof membrane

Classification of waterproofing membranes: Asphalt Coil, Polymer Modified Asphalt Based Waterproof Coil, and Polymer Coil

1 Asphalt coils

2Polymer modified bitumen-based waterproof coiled materials

The polymer modified bitumen-based waterproofing membranes mainly include bitumen paper felt and polymer modified bitumen waterproofing membranes.

A. Asphalt paper tire felt production and application

The production of bitumen felt in China has been declining year by year, and the current production and sales volume is very small.

China's petroleum bitumen linoleum was used since the early 1950s, and its output reached 190 million m2 by 1958. By the early 1980s when the reform and opening up began, the output of linoleum felt had risen to 530 million m2. With the reform and opening up, oil The rapid development of industry and construction industry, linoleum production enterprises through technological transformation, increase the production capacity of oxidized asphalt, to 1995, asphalt paper tire linoleum has a production emblem of up to 1.22 billion m2. As the construction of paper tar felts is still a traditional practice for many years, hot asphalt mastic is used as the bonding material. Environmental pollution has occurred in the hot mastic fat melting process and construction operations. Due to environmental reasons, some provinces and cities have expressly banned the use of paper tar felt construction in urban areas in recent years, and replaced them with high polymer modified bituminous waterproofing membranes. The paper felt linoleum, so the production bin of the paper felt fell to about 800 million m2, which greatly reduced the ratio.
