Description
Technical Field
The utility model relates to a waterproof coiled material, in particular to a modified asphalt waterproof coiled material, and belongs to the field of waterproof coiled materials.
Background
The waterproof coiled material is a coiled sheet waterproof material, and can be divided into an asphalt waterproof coiled material, a high polymer modified waterproof coiled material and a synthetic high polymer waterproof coiled material according to main waterproof constituent materials. Traditional asphalt felt and other waterproof materials are gradually eliminated because of the defects of toxicity, poor high and low temperature resistance and the like. At present, the polymer waterproof coiled material has been widely used in recent years due to its excellent waterproof and construction properties. However, the traditional polymer waterproof coiled material, such as a polyvinyl chloride waterproof coiled material, is made of single-layer polyvinyl chloride, so that the compression resistance and the deformation resistance of the coiled material are poor, the coiled material is contracted and expanded due to temperature change, and the coiled material is easy to break to form micropores, so that the waterproof performance of the waterproof coiled material is affected.
Disclosure of Invention
In order to solve the problems, the utility model designs the modified asphalt waterproof coiled material which has the advantages of low production cost, simple structure, elasticity, good fracture resistance effect, durability, high structural strength, good waterproof effect and convenient use.
The technical scheme of the utility model is as follows:
the utility model provides a modified asphalt waterproofing membrane, includes modified asphalt layer, modified asphalt layer is equipped with the upper and lower three-layer, namely goes up modified asphalt layer, well modified asphalt layer and lower modified asphalt layer, can effectually provide each attached point for the functional layer in the modified asphalt coiled material through setting up the modified asphalt layer of multilayer to each functional layer is in the same place through powerful gluey bonding connection, makes coiled material inside more stable firm, last modified asphalt layer and well modified asphalt layer between be equipped with the PE layer, the PE layer have mechanical strength height, ageing-resistant, puncture resistance is strong, coefficient of friction is big, flexible, corrosion-resistant etc. characteristics, well modified asphalt layer and lower modified asphalt layer between be equipped with polyester child layer, have good low temperature flexibility and ductility, the deformability that adaptation basic unit stress produced is strong, adopt the product of polyester child base to have characteristics such as big and crack resistance are good, lower modified asphalt layer bottom still is equipped with the plastic film layer, the plastic film layer has the isolation protection effect, go up modified asphalt layer top still be equipped with thin sand layer, can effectively be laid the coiled material when the surface of the coiled material can not be scratched by the firm ground surface by the surface of the coiled material through setting up reinforcing sand layer.
The PE layer contains impact resistance, puncture resistance modifier EVA or glass fiber for improving fracture resistance.
The thickness of the PE layer is 1mm-2 mm.
The plastic film layer is one of a polyvinyl chloride film layer, a polypropylene film layer and a polystyrene film layer.
The particle diameter of the fine sand layer is 0.5-2mm.
The utility model has the advantages that: low in production cost, simple in structure, flexible, good in fracture resistance effect, durable in use, high in structural strength, good in waterproof effect and convenient to use.
The utility model is further described below with reference to the drawings and examples.
