Abstract

The invention relates to a modified asphalt waterproof coiled material with an excellent flame-retardant property. The modified asphalt waterproof coiled material is provided with five layers of structures, the middle of the modified asphalt waterproof coiled material is a blank base layer, an upper flame-retardant modified asphalt layer and a lower flame-retardant modified asphalt layer are arranged on the upper side and the lower side of the blank base layer respectively, and surface isolation layers are arranged on the outer side of the upper flame-retardant modified asphalt layer and the outer side of the lower flame-retardant modified asphalt layer correspondingly; and the modified asphalt waterproof coiled material is characterized in that the upper flame-retardant modified asphalt layer and / or the lower flame-retardant modified asphalt layer are / is prepared from the following raw material of, in parts by mass, 50-70 parts of 100 model asphalt, 10-15 parts of an SBS modifier, 10-15 parts of softening oil, 5-10 parts of a silane coupling agent and 3-8 parts of a montmorillonite-based organophosphorus flame retardant. According to the modified asphalt waterproof coiled material, the organophosphorus flame retardant is stably attached to the surface of the montmorillonite powder in advance and then added into the modified asphalt, so that the flame retardance of the modifiedasphalt can be obviously improved, the flame retardant level of the waterproof coiled material is increased, and the waterproof coiled material has an excellent effect.

Description

technical field [0001] The invention belongs to the field of waterproof coiled materials, and relates to a modified asphalt waterproof coiled material with excellent flame retardancy and a preparation method thereof. Background technique [0002] Waterproof membranes are usually used on the top and side of various buildings, which can effectively block the penetration and leakage of external water into the interior of the building. At present, there are many types of waterproof membranes on the market with different performances. Classification from the base material of waterproof membranes, there are three main categories: polymer plastic waterproof membranes, such as PVC waterproof membranes, TPO waterproof membranes, etc.; rubber waterproof membranes, such as butyl rubber waterproof membranes, ternary B Propylene rubber waterproofing membrane, etc.; modified asphalt waterproofing membrane, such as SBS elastomer modified asphalt waterproofing membrane, APP plastic body mo...
