Problems solved by technology

Among them, asphalt coatings mainly include solvent-based and water-emulsion-based, which are widely used in various waterproof projects, but there are three fatal problems in the process of use: long construction period, health problems caused by volatile substances and poor impermeability
However, hot-melt modified asphalt waterproof coatings also have some disadvantages: firstly, the hot-melt construction temperature is high, causing serious volatilization of asphalt smoke, which is a waste of energy and not environmentally friendly; secondly, the adaptability to the base layer is limited and cannot be applied to deformation Seams and other places where large and frequent deformations are foreseeable

Abstract

The invention discloses hot melt type modified asphalt waterproof paint, which has the advantages that the creep performance is high, the basic layer deformation resistance capability is high, the fatigue resistance is good, the bonding strength is high, and in addition, good self healing capability is realized. Simultaneously, on the premise of 90 DEG C heat resisting experiments, the construction temperature of the paint is controlled to be lower 120 DEG C, the asphalt smoke is effectively reduced, and energy sources are saved. The paint can be coated for more than 3mm once and is independently used as a flexible waterproof layer with creep capability; and the paint can also be coated for more than 1mm to be used as a waterproof layer in a composite system, and a reliable composite waterproof layer is formed.

Description

technical field [0001] The invention relates to a hot-melt modified asphalt waterproof coating and a preparation method thereof. Its excellent creep properties enable it to effectively deal with the adverse effects of base layer deformation on the waterproof layer, and belongs to the field of building waterproof materials. Background technique [0002] Humans have a long history of using asphalt for waterproofing, and asphalt waterproofing materials still occupy an important position. Common asphalt waterproofing products in China include polymer modified asphalt waterproofing membranes and modified asphalt coatings, which have their own advantages and disadvantages in application range, construction conditions, and waterproof effect. Among them, asphalt coatings mainly include solvent-based and water-emulsion-based, which are widely used in various waterproof projects, but there are three fatal problems in the process of use: long construction period, health problems caused...
