Description
Technical Field
The invention belongs to the technical field of waterproof materials, and relates to a high polymer modified asphalt waterproof coiled material and a production process thereof.
Background
The high polymer modified asphalt waterproof coiled material is made up by using modified asphalt as material for dip-coating coiled material. The common petroleum asphalt material is easy to become hard and brittle and crack under the low temperature condition, has strong temperature sensitivity, and is softened at high temperature in summer under the action of ultraviolet light irradiated by sunlight for a long time so as to cause thermal desorption and repeated thermal expansion and cold contraction to cause the change of asphalt internal stress. Under the combined action of oxygen, ozone and the like, the chemical components in the asphalt are continuously transformed into a result, namely, oil volatilizes, the content of asphalt mastic is reduced, the plasticity is reduced, the brittleness is increased, the binding power is reduced, and cracks are generated to cause aging. The traditional petroleum asphalt waterproof material is difficult to meet the requirement of the waterproof service life of a building, so that the asphalt needs to be modified, and a certain amount of high polymer modifier is added into the asphalt, so that the inherent disadvantages of easy brittle fracture at low temperature and easy flowing at high temperature of the asphalt are improved.
The high polymer modified asphalt waterproof coiled material is used for waterproofing of railway bridge decks, highway bridge decks, building roofs and tunnels, and therefore, the requirements on waterproofness, extensibility and tear resistance of the high polymer modified asphalt waterproof coiled material are high. However, the existing high polymer modified asphalt waterproof coiled material has poor waterproofness, is easy to tear and leak after being used for a period of time, and has poor use effect.
Therefore, it is necessary to design a polymer modified asphalt waterproof coating with simple production process and good waterproof property and tear resistance to solve the above problems.
Disclosure of Invention
The invention provides a high polymer modified asphalt waterproof coiled material and a production process thereof, which solve the problem that the high polymer modified asphalt waterproof coiled material in the prior art is low in waterproofness and tear resistance.
The technical scheme of the invention is realized as follows:
the high polymer modified asphalt waterproof coiled material comprises a base course layer, a modified asphalt coating layer and an isolation layer, wherein the modified asphalt coating layer is prepared from the following raw materials in parts by weight:
