1、 What are the requirements for enterprises to pass the evaluation of green building materials for waterproofing membranes.

1. The enterprise has not had any major environmental pollution accidents or major production safety accidents within the past three years.

2. Enterprises need to provide comprehensive management system certification certificates, product type inspection reports, safety production standardization certificates, effective third-party environmental monitoring reports, EPD environmental impact and carbon footprint testing reports, and related enterprise application technical documents.

3. The storage and disposal of enterprise solid waste and hazardous mobile phones must strictly comply with relevant regulations such as GB18599 and GB18597.

2、 What harmful substances do SBS waterproofing membranes need to be tested for in order to pass the green building material evaluation.

According to the regulations in T/CECS10038-2019, waterproofing membrane products must not contain harmful substances. Specific testing items include benzene, ethylene glycol ethers and their esters, diamines, organic solvents, ketones, persistent organic pollutants, ozone depleting substances, phthalates, surfactants, polychlorinated biphenyls, perfluoroalkyl compounds, etc.

3、 What are the evaluation indicators for green building materials of asphalt waterproofing membrane.

1. Resource attribute: Fresh water consumption.

2. Energy attribute: energy consumption per unit product.

3. Environmental attribute: Total suspended particulate matter concentration.

4. Quality attributes: PVC waterproofing membrane asphalt softening point, water resistance (soaking time, tensile strength retention rate), hot air aging performance (time, tensile performance retention rate, low-temperature flexibility).

4、 What are the evaluation indicators for green building materials using polymer waterproofing membranes.

1. Resource attribute: Fresh water consumption.

2. Energy attribute: energy consumption per unit product.

3. Environmental attribute: Total suspended particulate matter concentration.

4. Quality attributes: water resistance (soaking time, tensile strength retention rate), hot air aging performance (elongation standard, tensile performance retention rate, low-temperature bending performance), artificial climate accelerated aging performance (time, tensile performance retention rate, TPO waterproof membrane low-temperature bending performance), thermal insulation performance (near-infrared emission ratio, solar emission ratio).

For products that meet the evaluation standards of green building materials for waterproofing membranes, production enterprises can use the "Green Building Selection Product" certification trademark. The "Green Building Selection Product" certification mark is issued by the National Building Materials Testing Center of China Construction Technology Center, which is used to prove that building material products meet the requirements of green building and green building material evaluation and are protected by law. Baien Testing can help enterprises carry out the evaluation of green building materials for waterproofing membranes. As long as they obtain the green building material evaluation report, it will play a positive role in promoting the application, procurement, brand building and transformation upgrading of polymer self-adhesive membrane waterproofing membranes for enterprises.

Classification.

The waterproof material product made by impregnating asphalt or polymer waterproof materials on the tire body, provided in the form of a roll, is called a waterproof roll. According to the main composition materials, it is divided into asphalt waterproof roll, polymer modified asphalt waterproof roll, and synthetic polymer waterproof roll. According to the different tire bodies, it is divided into non tire body roll, paper tire roll, glass fiber tire roll, glass cloth tire roll, and polyethylene tire roll.

Waterproof coiled material is required to have good water resistance, stability to temperature changes (no flowing, bubbling, stirring, and embrittlement at high temperature), certain mechanical strength, extensibility, and fracture resistance of liquid coiled material, as well as certain flexibility and aging resistance, [1]。

Waterproof roll material is a curled sheet waterproof material and one of the important varieties in building waterproofing materials.

According to its main waterproof components, it can be divided into three categories: asphalt waterproof materials, polymer modified waterproof rolls, and synthetic polymer waterproof rolls (SBC120 polyethylene polypropylene composite rolls). There are various waterproof rolls such as PVC, EVA, PE, ECB, etc.

Asphalt waterproofing membrane is a rollable sheet-like waterproofing material made by immersing asphalt on the base tire (such as raw paper, fiber fabric) and then spreading powdered or sheet-like insulation material on the surface.
