Petroleum coke high polymer modified asphalt waterproof coiled material and preparation method thereof

Abstract

The invention discloses an asphalt waterproof coiled material added with petroleum coke as a modifier. The asphalt waterproof coiled material comprises a tire base layer and self-adhesive coating layers arranged on the upper surface and the lower surface of the tire base layer, an upper surface covering layer is arranged above the self-adhesive coating layer on the upper surface of the tire base layer, and a lower surface covering layer is arranged below the self-adhesive coating layer on the lower surface of the tire base layer; wherein the self-adhesive coating layer is prepared from the following components in parts by weight: 35 to 45 parts of 70# to 100# petroleum asphalt; 2-8 parts of SBS thermoplastic elastomer rubber; 1.5-5 parts of SBR butadiene styrene rubber powder; 5-10 parts of base oil; 2-5 parts of a tackifier; 1-3 parts of a silane coupling agent; 10-20 parts of rubber powder; 1-5 parts of petroleum coke; and 20-30 parts of filler. Herein, the petroleum coke is used for partially replacing petroleum asphalt and also serves as an asphalt modifier and filler to improve the stability and weather resistance of the coiled material and improve the plasticity, wear resistance and mechanical strength performance of the coiled material, so that the prepared coiled material is good in tensile strength, high in extensibility and excellent in self-healing performance and waterproof performance. The invention also discloses a preparation method of the asphalt waterproof coiled material.

Description

technical field

[0001] The invention belongs to the field of building waterproof materials, and more specifically relates to a petroleum coke high polymer modified asphalt waterproof coiled material and a preparation method thereof. Background technique

[0002] Waterproof membrane is mainly used in building walls, building basements, floors, roofs, tunnels, roads, landfills, etc., to resist the penetration of external rainwater and groundwater. It is a flexible building material product that can be rolled into rolls. , as the non-leakage connection between the engineering foundation and the building, it is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. Common waterproofing membranes mainly include polymer modified asphalt waterproofing membranes and polymer waterproofing membranes. Polymer-modified asphalt waterproofing membrane is a medium-to-high-end waterproofing material due to its excellent high and low temp...
