Problems solved by technology

The two types of products in the prior art are APP modified asphalt waterproofing membrane and SBS modified asphalt waterproofing membrane. The former is not suitable for use in northern regions due to insufficient low temperature resistance, low temperature flexibility and low temperature strength. Insufficient high temperature resistance performance, continuous high temperature for a long time, softening and flowing, not suitable for use in southern regions
And both of them have low puncture resistance, cyclic load resistance and bonding performance

Abstract

The invention belongs to the technical field of organic polymer composite materials and particularly relates to a polybasic polymer resin and petroleum asphalt blending material and a waterproof roll prepared from the same. According to the technical scheme, the polybasic polymer resin and petroleum asphalt blending material is characterized in that polybasic polymer resin comprises the following components in parts by weight: 6-12 parts of heat-resisting reinforced resin, 12-15 parts of thermoplastic resin, 2-8 parts of low-carbon petroleum resin, 4-8 parts of engine oil, 10-20 parts of mineral powder and 40-50 parts of asphalt. The polybasic polymer resin and petroleum asphalt blending material has high tensile strength, heat resistance, binding performance and low-temperature toughness.

Description

technical field [0001] The invention belongs to the technical field of organic polymer composite materials, and in particular relates to a multi-component polymer resin and petroleum asphalt blend material and a prepared waterproof coiled material. Background technique [0002] Polymer modified bitumen waterproofing membrane is one of the most important types of materials used in waterproofing projects, and is widely used in various waterproofing projects. Its typical products are SBS elastomer modified bitumen waterproofing membrane and APP plastomer modified bitumen waterproofing membrane, which are respectively suitable for waterproofing projects of common roofs in low temperature areas and high temperature areas. However, in recent years, there have been many special waterproofing projects in the construction field. For example, the top surface of a large underground parking garage is a ground square or a parking lot, and its load and deformation are relatively complicat...
