Problems solved by technology

Hot-melt construction of SBS modified asphalt waterproofing membrane on shale surface will produce asphalt fume and cause air pollution; cold self-adhesive construction is convenient and pollution-free, but there is a problem of poor self-adhesive effect of self-adhesive layer
[0003] The preparation process of modified asphalt waterproofing membrane on shale surface mainly includes polyester base impregnation-oiling-edge film-cloth sand-water bed cooling-covering isolation film or polyester base impregnation-oiling-edge film -Water bed cooling-cloth sand-covering isolation film; Among them, water cooling after spreading first has the problems of uncontrollable overlapping edges and easy water immersion in the cooling process, and then the surface temperature of the spreading process is low, which will lead to weak shale bonding; And in the prior art, both sides of the polyester subbase of the waterproofing membrane produced by this dipping and oiling production method must be the same kind of asphalt coating material, and it is impossible to realize the production of different asphalt coating materials on the upper and lower sides of the polyester subbase, so , the shale surface self-adhesive modified bitumen waterproofing membrane produced by the existing process is either a pure self-adhesive system whose exposed heat resistance does not meet the requirements, or a sandwich system, that is, SBS is first coated on the upper and lower sides of the polyester base Modified asphalt layer, and then self-adhesive asphalt layer on the lower surface of the modified asphalt layer, although such a sandwich system can meet the requirements of exposed temperature resistance, but the thickness of the self-adhesive coating is not easy to control, which affects the bonding effect

preparation example Construction

[0017] One aspect of the present invention provides a method for preparing a composite self-adhesive shale surface modified asphalt waterproof membrane, the preparation method comprising:

[0018] The polyester tire is pre-impregnated, squeezed, coated with surface modified asphalt coating material, edge covering film, cloth sand, roller compaction, turning roll turning, and coated with the second knife coating box in the first knife coating box. The self-adhesive modified asphalt coating material on the lower surface, the isolation film, and the roll are cooled and shaped to obtain the composite self-adhesive shale surface modified asphalt waterproofing membrane.

[0019] The production of modified asphalt waterproofing membranes in the prior art mainly adopts the dipping-oiling process. Based on the problems existing in the existing dipping-oiling process, the present invention realizes scraping-coating of asphalt on the upper and lower surfaces of the polyester base by scrap...

Abstract

The invention discloses a composite self-adhesive shale surface modified asphalt waterproof roll and a preparation method thereof. The preparation method comprises the steps that a polyester base is sequentially subjected to preimpregnation and squeezing, the upper surface of the polyester base is coated with a modified asphalt masking material by a first scraping-coating box, side membranes are applied, sand application is performed, rolling compaction is performed, a turning roller turns, the lower surface of the polyester base is coated with a self-adhered modified asphalt masking materialby a second scraping-coating box, an isolating membrane is applied, roller cooling is performed for formation, and the composite self-adhesive shale surface modified asphalt waterproof roll is obtained. The polyester base modified asphalt waterproof roll is produced by adopting a scraping-coating process through process innovation, and modified asphalt waterproof rolls with upper and lower surfaces made of different asphalt masking materials can be produced. In addition, the links such as discharging from an oil bath, roller heating and water cooling are omitted, and the energy consumption ofa production line is effectively reduced by 20% or above.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled materials, and more specifically relates to a composite self-adhesive shale surface modified asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] The modified asphalt waterproofing membrane for shale surface is currently the only one of the modified asphalt waterproofing membranes that is mass-produced and exposed. The construction methods are divided into hot-melt construction and cold self-adhesive construction. Hot-melt construction of SBS modified asphalt waterproofing membrane on shale surface will produce asphalt smoke and cause air pollution; cold self-adhesive construction is convenient and pollution-free, but there is a problem of poor self-adhesive effect of self-adhesive layer.
