Description

High-strength high polymer modified asphalt waterproof coiled material, waterproof system, preparation method and application
Technical Field
The invention belongs to the field of modified asphalt waterproof coiled materials, and particularly relates to a high-strength high polymer modified asphalt waterproof coiled material, a waterproof system, a preparation method and application.
Background
The high polymer modified asphalt waterproof coiled material is a waterproof coiled material which is prepared by taking asphalt as a main body waterproof material, adding modifiers such as SBS, IPP, APAO and the like into the asphalt to improve the high-temperature anti-flowing performance and the low-temperature anti-brittle-cracking performance of the asphalt to obtain modified asphalt, coating the modified asphalt on the upper surface and the lower surface of a middle layer matrix such as a polyester matrix, a glass fiber matrix or a glass fiber reinforced polyester matrix, coating an isolating material, and curling. The middle layer matrix plays a role of an asphalt coiled material framework and endows the asphalt coiled material with higher tensile strength and maximum tensile strength elongation.
The strength of the middle layer carcass is improved along with the increase of the fiber amount and the thickness of the carcass base, and the currently common thickest polyester tire has the specification of 310g/m2Continuing to increase the thickness affects the impregnation of the base, the compactness of the intermediate layer, and the waterproofing function of the intermediate layer.
Taking roof waterproofing as an example, for important building waterproofing engineering, two waterproof materials must be used for waterproofing to achieve I-level waterproofing, and the currently selectable schemes mainly include three schemes of coiled material + coiled material, coiled material + asphalt coating, coating + enhancement layer + coating.
The coiled material + coiled material scheme has double-deck protection, is the strongest combination scheme, however because the higher heat resistance of pitch coiled material, no matter the coiled material is hot melt construction or self-adhesion construction, the full construction of gluing of coiled material and basic unit all has certain strict condition restriction, realizes the difficulty.
The scheme of the coiled material and the asphalt coating is that the asphalt coating layer lacks deformation resistance.
The scheme of coating, the reinforced layer and the coating has excellent deformation resistance, but the operation is troublesome, and the construction period is too long.
According to the composite construction scheme of the coiled material and the polyurethane coating, the molecular structure difference of the main material is large, the bonding effect is poor, and the use quality requirement of composite construction cannot be met.
Therefore, in order to solve the problem that the existing waterproof system is difficult to achieve the I-level waterproof grade, a novel modified asphalt waterproof coiled material, a waterproof system, a preparation method and application thereof are urgently needed to be provided.
