Description

Hot-melt rubber asphalt waterproof coating, preparation method thereof, hot-melt rubber asphalt waterproof coating sealing tape and waterproof coiled material lap joint method
Technical Field
The invention belongs to the technical field of waterproofing, and in particular relates to a hot-melt rubber asphalt waterproof coating and a preparation method thereof, a hot-melt rubber asphalt waterproof coating sealing tape and a waterproof coiled material lap joint method.
Background
In recent years, the non-cured hot-melt rubber asphalt waterproof coating is widely applied to the domestic waterproof market, has strong self-healing capacity, and can effectively solve the water quick-boiling problem when being used as a bottom auxiliary coating and a coiled material in a combined way. However, non-cured asphalt coatings still suffer from the following drawbacks: 1) Because of the characteristic of never solidification, the waterproof material is easy to deform and flow at high temperature, thereby further limiting the application of the waterproof material in the fields of building waterproofing such as sloping roofs, standing walls, compounding with exposed coiled materials and the like. 2) Because the non-cured hot melt rubber asphalt waterproof coating has lower strength, although the crack and capillary holes of the base layer can be well sealed, the bonding strength is lower, the water pressure is not resistant, when the non-cured hot melt rubber asphalt waterproof coating is applied to underground waterproof engineering with pressure-bearing water, the base layer and the waterproof layer are easily peeled off, and the composite upper waterproof layer is leaked once the composite upper waterproof layer is leaked, so that the leakage of a 'coil coating' composite waterproof system is caused, and the risk is high. 3) At present, aiming at a non-cured coil coating composite system, after non-cured construction is finished, the joint edges still need to be treated independently, open fire construction cannot be completely avoided, and the construction efficiency is affected. Based on the current market environment demands, open fire construction is more and more limited, which can certainly have great influence on the application of SBS modified asphalt waterproof coiled materials and non-curing coiled coating composite systems.
In view of the problems of low strength and non-film formation of the non-cured hot melt rubber asphalt waterproof coating, a high-strength anti-slip water-based asphalt coating mainly comprising more asphalt latex is developed in the current market, however, the water-based asphalt coating has low solid content, long film forming time and needs to be thick for multiple times, and the construction process is seriously influenced by re-open flame construction after film formation.
Asphalt waterproof coiled materials are waterproof products with the largest application amount in the current building waterproof market and most trusted by customers, however, the short-side lap joint problem of the modified asphalt waterproof coiled materials with fine sand and mineral particles on the surfaces is the biggest waterproof weak point: the waterproof coiled material with fine sand or mineral aggregate on the surface is prepared by using a traditional sand setting process when the short edges are overlapped, roasting the mineral aggregate on the short edges by fire, pressing down the fine sand or mineral aggregate, flooding asphalt oil, and then carrying out short edge overlapping, wherein the requirement on the technical level of construction workers is high, sand is pressed to a base, water leakage and hidden danger are easily caused, the short edge overlapping of the fine sand and the mineral aggregate is not limited by the national standard at present, and the peeling strength of the messy image of the short edge overlapping of the asphalt waterproof coiled material is far lower than the requirement of the national standard on long edge overlapping (more than or equal to 1.5N/mm). Based on the water leakage hidden trouble of the modified asphalt waterproof coiled material of fine sand and mineral particles is greatly increased.
