Abstract

The invention relates to a modified asphalt waterproof coiled material and a preparation method thereof. The modified asphalt waterproof coiled material comprises an isolating layer, a lower surface modified asphalt layer, a padding layer, an upper surface modified asphalt layer and a particle layer. The lower surface modified asphalt layer is made from the following raw materials: asphalt 90#, butadiene styrene rubber, polymethyl silicone, APAO, vermiculite powder, cordierite micro powder, tetracosanoic acid, alkyl polyglucosides, DMHAC10, a softener and a stabilizer; and the upper surface modified asphalt layer is made from the following raw materials: asphalt 90#, butadiene styrene rubber, AEO, Carbomer, APAO, spodumene powder, vermiculite powder, cordierite micro powder, a softener, aplasticizer and a stabilizer. Different modified asphalt layers are arranged on the two sides of the padding layer of the waterproof coiled material to reduce the phenomenon that the waterproof coiledmaterial slips during the following using process after construction of a vertical wall and also avoid the phenomenon that the waterproof coiled material is aged due to long-time irradiation after construction of the vertical wall.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled materials, in particular to a modified asphalt waterproof coiled material for building exterior walls and a preparation method thereof. Background technique [0002] Waterproof membrane is a rollable sheet waterproof material. It is one of the important varieties of waterproof materials for construction projects. According to its main waterproof composition materials, it can be divided into three categories: asphalt waterproof materials, polymer modified waterproof membranes and synthetic polymer waterproof membranes. Bitumen waterproofing membrane is a rollable sheet-shaped waterproof material made by dipping asphalt on the base tire and then spreading powdery or sheet-like isolation materials on the surface. [0003] The main components of asphalt are asphaltenes and resins, followed by high-boiling mineral oil and a small amount of oxygen, sulfur and chlorine compounds. Asphalt is ...
