Problems solved by technology

However, there are also some confusions, misoperations, and material deficiencies in design, construction, waterproof materials and waterproof engineering quality control, and the waterproof quality is not satisfactory. CN110406187A discloses ARF-999 gold steel armor macromolecule Pre-paved waterproof membrane, the obtained polymer pre-paved waterproof membrane has better compactness, good waterproof and adhesion
[0004] However, the amount of pre-laid anti-adhesive medium-polymer self-adhesive film is the largest on the construction site, and the problem is also more prominent. It is easy to damage the coiled material during the process of lifting steel bars and binding steel bars on the polymer self-adhesive film. Once the waterproof layer If the water is damaged, the water will flow everywhere, it is difficult to find the penetration point, the maintenance is very difficult, and it may even lead to the failure of the waterproof layer as a whole. pre-laid rolls

Abstract

The invention relates to C09J, in particular to a polymer modified asphalt material, emery coated asphalt and an anti-sticking waterproof coiled material. The high-molecular modified asphalt material is prepared from the following raw materials in percentage by weight: the balance of asphalt, a high-molecular polymer, a dispersing agent and a mineral filling agent. Polyolefin such as thermoplastic polyolefin is added as a modified polymer, so that the high temperature resistance of the modified material is improved, the chemical resistance can be improved, and the use of the modified material on a pre-paved waterproof coiled material is promoted. The dispersing agent, the filler and the like are added, so that the dispersion effect of macromolecules in the asphalt grinding process can be promoted, particularly, the proper dispersing agent is used, and the selection of the macromolecules and the asphalt is controlled, so that the dispersion effect can be promoted while the needle penetration is improved without adding an oil agent, and the formed asphalt material is used in the waterproof coiled material; and the pre-paving anti-sticking requirement is met, and meanwhile, high penetration resistance, tear resistance and thermal and chemical stability are achieved.

Description

technical field [0001] The invention relates to C09J, more specifically, the invention relates to a polymer modified asphalt material, emery-coated asphalt, and anti-adhesive waterproof coiled material. Background technique [0002] Underground waterproofing is an important part of building construction. Using traditional SBS modified asphalt waterproofing materials as the waterproof layer is difficult to maintain when the building leaks, and the source of leakage is often not found. The success of the basement waterproofing project is also related to Whether the building can be put into use perfectly. The traditional SBS modified asphalt waterproof material is used to lay on the cushion layer, then make a protective layer, and then pour the structural bottom plate. The waterproofing layer does not form a bond to the structural base. When the waterproof layer is damaged, groundwater will flow between the waterproof layer and the structural layer. Since the structural bott...
