Abstract

The invention relates to the technical field of waterproof coiled materials, in particular to a high-durability SBS (styrene-butadiene-styrene) modified asphalt waterproof coiled material which comprises a base layer, SBS modified asphalt coating materials coated on the upper surface and the lower surface of the base layer, and isolating membranes covered on the surfaces of the coating materials, the SBS modified asphalt coating material comprises the following components in parts by mass: 100 parts of petroleum asphalt, 4-9 parts of vegetable asphalt, 9-15 parts of SBS and SIS, 0.4-1 part of a warm mixing agent, 4-8 parts of talcum powder, 1-3.5 parts of zinc borate and 5-9 parts of vegetable oil.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled materials, in particular to high-durability SBS modified asphalt waterproof coiled materials. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis There is no seepage connection with the building, which is the first barrier for the waterproofing of the whole project and plays a vital role in the whole project; the products mainly include asphalt waterproofing membrane and polymer waterproofing membrane. [0003] At present, SBS modified bitumen waterproofing membrane is one of the most important and common waterproofing membrane products with moderate price, good waterproofing effect and convenient construction. However, as the waterproof engineering design requires that it...
