Abstract

The invention relates to a polymer modified asphalt waterproof coiled material with good aging resistance and a preparation method thereof. The polymer modified asphalt waterproof coiled material comprises a base layer, the upper and lower surfaces of the base layer are both provided with modified asphalt layers, and the upper and lower modified asphalt layers are both covered with isolation layers. The spodumene powder and the silicon carbide powder are added into the modified asphalt layer of the waterproof coiled material; the spodumene powder contains a large amount of LiO2 and a small amount of Al2O3, SiO2 and CeO2; on one hand, the spodumene powder can be used as a filler, and on the other hand, Al2O3, SiO2, CeO2 and SiC in the spodumene powder have mutually matched band gap energy,so that absorption and heat dissipation of ultraviolet rays can be realized, aging of the asphalt layer caused by the ultraviolet rays is prevented, and the waterproof coiled material has excellent aging resistance.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material, in particular to a polymer-modified asphalt waterproof coiled material with good aging resistance 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. Aspha...
