Problems solved by technology

[0003] At present, most self-adhesive asphalt waterproofing membranes are elastomer-modified rubber materials. The cohesive force of the asphalt rubber material is relatively large, and it cannot fully bond with the fine cracks and potholes in the base layer, especially when the cracks in the base layer expand. The zero-extension fracture length of the rubber material of the coil is limited, and the self-adhesive layer is under stress for a long time, which accelerates the aging of the coil. It is easy to fall off from the base layer and will not leave glue on the base layer, thus losing the waterproof performance

Abstract

The invention relates to a creeping self-adhesive asphalt water-proof coiled material and a preparation method thereof. An asphalt sizing material used for the creeping self-adhesive asphalt water-proof coiled material has good adhesive property and creeping property, and the asphalt sizing material is prepared from the following raw materials in percentage by weight: 35%-55% of petroleum asphalt, 5%-25% of softening agent, 5%-25% of modifying agent, 2%-8% of tackifying agent, 0.1%-2% of interface agent, 0.1%-3% of anti-aging agent and 5%-20% of filling agent. The self-adhesive asphalt water-proof coiled material disclosed by the invention has very good initial adhesion, can be well adhered with a base layer under the conditions of the wet base layer and lower temperature even if a little dust is positioned on the surface of the base layer, is difficult to strip after being adhered, and can ensure that a complete sizing material can be retained on the base layer after being stripped, thus meeting the requirement for water-proof property.

Description

technical field [0001] The invention belongs to the building waterproof material technology, in particular to a creep type self-adhesive asphalt waterproof coiled material and a preparation method thereof. technical background [0002] Self-adhesive bitumen waterproof membrane is a new type of waterproof material developed in recent years. It is suitable for roofs, basements, interiors, municipal works and reservoirs, swimming pools and subway tunnel waterproofing, wooden and metal structure roofs of industrial and civil buildings. It is especially suitable for military facilities that require cold construction and waterproof projects such as oil depots, chemical plants, textile mills, and grain depots that are not suitable for using open flames. [0003] At present, most self-adhesive asphalt waterproofing membranes are elastomer-modified rubber materials. The cohesive force of the asphalt rubber material is relatively large, and it cannot fully bond with the fine cracks an...
