[0003] At present, the domestic elastomer (SBS) modified asphalt waterproofing membrane is still the mainstream product, especially when it is used on the exposed roof, because of its superior high temperature resistance, it is difficult to be replaced by other materials. The waterproof membrane needs to be hot-melt during construction. There is a great fire hazard when the open flame is baked by the blowtorch. During the baking process, the burning of the surface PE film and the decomposition of some modified asphalt rubber will also produce some secondary substances. Oxygens, hydrocarbons, etc., causing serious pollution to the environment
[0004] Self-adhesive membrane is a new type of waterproof material that can be constructed at room temperature and does not require hot-melt construction. It is currently favored by the market, and its growth rate far exceeds that of elastomer (SBS) modified bitumen waterproof membrane. However, this self-adhesive membrane The heat resistance of the adhesive membrane is only 70°C, while on the roof, due to the characteristics of heat absorption and heat storage of the waterproof material, it is easy to reach above 70°C in summer. The life of the modified asphalt coil has been affected by the long-term high-heat environment. In view of some disadvantages of these two materials, the present invention aims to achieve safe, convenient, environmentally friendly and durable through formula adjustment and special coil structure.

Abstract

The invention discloses a self-adhesive waterproof asphalt coil material. The coil material comprises a mineral aggregate layer, a first high-heat-resistant elastomer modified asphalt size layer, a polyester base layer, a second high-heat-resistant elastomer modified asphalt size layer, a self-adhesive high-heat-resistant asphalt size layer and an isolation membrane layer, which are arranged sequentially from top to bottom. According to the coil material, the remarkable high-temperature resistance of the product is realized by using the mineral aggregate layer, the two high-heat-resistant elastomer modified asphalt size layers and the polyester base layer; the bottom layer is coated with the self-adhesive high-heat-resistant asphalt size layer, so that the construction is convenient, and meanwhile, the high-temperature resistance of the product is further improved.

Description

technical field [0001] The invention relates to a self-adhesive asphalt waterproof coiled material, which belongs to the fields of building waterproof materials and civil engineering waterproofing. Background technique [0002] SBS thermoplastic elastomer first appeared in the United States in the early 1960s, and soon developed SBS modified asphalt in France and named it elastic asphalt. Because SBS modifier has a variety of excellent characteristics, it spread rapidly in Europe and spread to Japan and the United States. Currently, SBS is still the first choice for modified asphalt materials. The combination of SBS elastomer modified bitumen and filament polyester non-woven fabric makes the performance of SBS modified bitumen waterproof membrane more perfect and enters the ranks of high-grade waterproof materials, and is widely used in the field of waterproofing. In countries such as Germany, France, Finland and Norway, SBS modified bitumen waterproofing membrane accounts...
