A modified asphalt waterproof coiled material and a manufacturing method thereof

Abstract

A modified asphalt waterproof coiled material and a manufacturing method thereof are disclosed. The coiled material comprises an upper cover layer, a lower cover layer, modified asphalt layers and a middle matrix layer. One of the modified asphalt layers is disposed between the upper cover layer and the middle matrix layer and the other modified asphalt layer is disposed between the lower cover layer and the middle matrix layer. The upper cover layer comprises following raw materials by weight: 180-270 parts of 90# asphalt, 30-90 parts of rubber powder, 10-40 parts of SBS, 10-20 parts of SBR, 8-18 parts of hydrogenated petroleum resin, 35-55 parts of naphthenic oil, 70-90 parts of mountain flour, 0.1-1.5 parts of an ultraviolet ray absorber and 0.2-1 part of an antioxidant. The modified asphalt layers comprise following raw materials by weight: 60-120 parts of 90# asphalt, 5-15 parts of 10# asphalt, 12-18 parts of active silica regenerated powder, 4-6 parts of SBR, 30-40 parts of cut 3 machine oil and 20-30 parts of APP. According to the coiled material and the method, a high-temperature anti-flowing property and a low-temperature cracking property of the modified asphalt waterproof coiled material are largely improved, the modified asphalt waterproof coiled material is provided with a self-adhesion elastomer, and using performance of the coiled material is enhanced.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to a modified asphalt waterproof coiled material and a manufacturing method thereof. Background technique [0002] Waterproof membrane is a commonly used building material in building construction. Through years of practical application engineering statistics, asphalt waterproof membrane ranks first, and it is a common waterproof material that is most widely used in buildings in my country. It is popular in construction and design departments because of its low price and convenient use. It is used in a large and wide range. It is mainly used for foundation waterproofing at the bottom of buildings, and some are used for exposed parts such as roofs; traditional modified bitumen waterproofing membranes are based on SBS is mainly modified. If you add more, the cost will increase. If you add less, the performance will be unstable and the storage time will be short. However, th...

[0002] Waterproof membrane is a commonly used building material in building construction. Through years of practical application engineering statistics, asphalt waterproof membrane ranks first, and it is a common waterproof material that is most widely used in buildings in my country. It is popular in construction and design departments because of its low price and convenient use. It is used in a large and wide range. It is mainly used for foundation waterproofing at the bottom of buildings, and some are used for exposed parts such as roofs; traditional modified bitumen waterproofing membranes are based on SBS is mainly modified. If you add more, the cost will increase. If you add less, the performance will be unstable and the storage time will be short. However, the coil often needs to be heated to make it melt during the laying process, which requires the coil to have high temperature. The anti-flow ability, when waterproofing, requires the membrane to have low-temperature cracking ability, so it is necessary to design a modified asphalt membrane with low production price and high stability when encountering temperature changes to solve the above problems
