Description

Technical Field

[0001] The utility model belongs to the field of waterproof coiled materials, and more specifically, relates to a modified asphalt waterproof coiled material that can be exposed outdoors. Background Art

[0002] The waterproof coiled material is a composite material with waterproof function. After decades of development, it has become an industry with an industrial scale of 200 billion yuan. Among them, the modified asphalt waterproof coiled material, as a type of product in the waterproof coiled materials, has a wide range of applications, a moderate price, and has good application prospects.

[0003] The modified asphalt waterproof coiled material is mainly divided into two types: hot-bonding type and cold-bonding type according to the construction method. The hot-bonding type modified asphalt waterproof coiled material uses heating to melt the modified asphalt layer and bond it with the base layer. The construction operation is relatively troublesome, and it requires energy such as gas for heating, with high energy consumption and high construction cost. However, the modified asphalt material of the hot-bonding type coiled material has a lower penetration and better heat resistance. It can resist being stepped on by people in summer when the temperature is relatively high. If the upper surface is coated with mineral aggregates, it can meet the requirements for outdoor use. The cold-bonding type modified asphalt coiled material does not require heating and can be constructed after tearing off the release film. The operation is convenient and the construction cost is relatively low. However, the cold-bonding type coiled material has a lower penetration and lower heat resistance requirements. It is softer at high temperatures and is prone to deformation after being stepped on by people, and cannot meet the outdoor requirements.

[0004] The coiled material that can be exposed outdoors has good application prospects and the market demand is increasing day by day. Therefore, a modified asphalt waterproof coiled material that can be constructed by the cold-bonding method, with fast and convenient construction, saving construction costs, and meeting the outdoor use requirements has good market prospects.
