Problems solved by technology

[0005] The coil + coil scheme has double-layer protection, which is the strongest combination scheme. However, due to the high heat resistance of the asphalt coil, no matter whether the coil is hot-melt construction or self-adhesive construction, the full-adhesion construction of the coil and the base layer exists. There must be strict conditions and restrictions, and it is difficult to realize
[0006] Coil + asphalt coating solution, the asphalt coating layer lacks deformation resistance
[0007] Coating + reinforcing layer + coating scheme, with excellent anti-deformation ability, but troublesome operation and long construction period
[0008] The composite construction scheme of coil material and polyurethane coating cannot meet the quality requirements of composite construction due to the large difference in the molecular structure of the main material and the poor bonding effect
[0009] Therefore, in order to solve the problem that the current waterproof system is difficult to achieve the first grade of waterproofing, it is urgent to propose a new type of modified bitumen waterproofing membrane and waterproofing system, as well as its preparation method and application.

Abstract

The invention belongs to the field of modified asphalt waterproof coiled materials, and discloses a high-strength high polymer modified asphalt waterproof coiled material, a waterproof system, a preparation method and application. The high-strength high polymer modified asphalt waterproof coiled material comprises an upper covering isolation material layer, an upper surface modified asphalt coating layer, a middle reinforcement layer, a lower surface modified asphalt coating layer and a lower covering reinforcement layer which are sequentially arranged; the upper covering surface isolation material layer comprises an upper covering surface isolation film and an overlapping edge film arranged at one end of the upper covering surface isolation film; and the lower covering enhancement layer is a non-woven fabric. The modified asphalt waterproof coiled material disclosed by the invention has excellent tensile property, super-strong tear resistance and relatively strong perforation resistance, and can be fully compounded with a coating layer to form a novel 'one-roll, one-cloth and one-coating' waterproof system which is high in strength, tear-resistant and puncture-resistant.

Description

technical field [0001] The invention belongs to the field of modified asphalt waterproof coiled material, and in particular relates to a high-strength polymer modified asphalt waterproof coiled material, a waterproof system, a preparation method and an application. Background technique [0002] Polymer modified asphalt waterproofing membrane is a kind of waterproof material with asphalt as the main body, and SBS, IPP, APAO and other modifiers are added to the asphalt to improve the high-temperature anti-flow performance and low-temperature anti-brittle performance of asphalt. Then apply the modified asphalt on the upper and lower surfaces of the middle layer carcass such as polyester tire, glass fiber tire or glass fiber reinforced polyester tire, and then cover the insulation material, and curl the waterproof membrane. Among them, the middle layer carcass acts as the skeleton of the asphalt coil, endowing the asphalt coil with higher tensile strength and maximum tensile str...
