Modified asphalt coating material and preparation method thereof and mineral pellet-modified asphalt waterproof coil material and preparation method of mineral pellet-modified asphalt waterproof coil material

Abstract

The invention discloses a modified asphalt coating material and a preparation method thereof and a mineral pellet-modified asphalt waterproof coil material and a preparation method of the mineral pellet-modified asphalt waterproof coil material. The modified asphalt coating material includes: in parts by mass, 45-50 parts of petroleum asphalt, 5-10 parts of hot-mix asphalt, 12-15 parts of SBS, 2-4parts of polyethylene wax, 2-5 parts of tackifying resin and 20-35 parts of filler. Through the mineral pellet-modified asphalt waterproof coil material, the defects of insufficient base strength ofexisting waterproof coil materials, poor adhesion of mineral pellets, no owning of fluidity and heat resistance of the coating material and the like can be overcome, the use demands of passive buildings for special mineral pellet surface modified asphalt waterproof coil materials can be satisfied, and the gap in the domestic market is filled up, so that a relevant technology is provided for special waterproof coil materials of passive buildings in China, a guiding significance is achieved.

Description

Technical field [0001] The invention belongs to the technical field of modified asphalt waterproof coiled materials, and more specifically relates to a modified asphalt coating material and a preparation method thereof, and a mineral pellet modified asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] Passive ultra-low energy building (passive building) refers to the full use of natural environment and resources, and various passive energy-saving methods such as natural ventilation, natural lighting, solar radiation and indoor non-heating heat sources, etc. A building constructed by combining energy-saving technologies. Conventional green buildings generally have an energy-saving effect of 50% to 75%, while passive buildings have an energy-saving effect of more than 90%, which is an important way to save energy and reduce emissions in future buildings. Combining green energy is meaningful for the sustainable development of society. A...

Problems solved by technology

[0004] At present, due to the main disadvantages of the existing mineral granule modified bitumen waterproofing membranes are as follows: 1. Common mineral granule surface modified bitumen waterproofing membranes use polyester tires, which are easily deformed by external stress after construction, resulting in rolls The material shrinks or tears; 2. The mineral granules of the ordinary mineral granule surface modified asphalt waterproofing membrane have poor adhesion to the coating material, and the colored shale is easy to fade after being exposed to wind, sun, and ultraviolet rays; 3. Ordinary The coating material of the modified asphalt waterproofing membrane with mineral grain surface has a high viscosity, and the tire base will be narrowed and deformed during the production process; 4. The heat resistance of the coating material of ordinary mineral grain surface modified asphalt waterproof membrane It is difficult to balance the performance and fluidity. At present, there is no coating material that can meet the heat resistance requirements of the modified asphalt waterproofing membrane for passive houses while ensuring good fluidity; The aging resistance of permanent asphalt waterproofing membrane cannot meet the requirements of the use of modified asphalt waterproofing membrane for passive houses

[0005] To sum up, the stability and aging resistance of the current ordinary mineral granular surface modified asphalt waterproofing membrane cannot meet the requirements of passive houses, and there is no special modified asphalt waterproofing membrane suitable for passive houses.
