Problems solved by technology

However, due to the disadvantages of poor flexibility, low elongation, easy cracking at low temperature, especially hot flow and brittleness of asphalt, the above two modified asphalt coatings have defects to varying degrees during use.
Among them, the production method of water-emulsified asphalt paint is cumbersome, and the biggest disadvantage is that because the paint is water-based, the film-forming compactness is poor, so the water resistance and aging resistance are poor; solvent-based asphalt paint cannot be used indoors due to the presence of a large amount of organic matter.
Especially in poorly ventilated kitchens and bathrooms and buildings, one is to prolong the period of construction work, and the other is to cause health effects on workers

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to an asphalt-based waterproof coating for construction, which is mainly used in various construction waterproofing projects. Background technique [0002] Asphalt has a long history of being used for waterproofing. This is because asphalt has good waterproofness and durability. It is still an important material for building waterproofing. It has cheap and abundant raw materials, easy construction, strong waterproof function, and long waterproofing period. Salient features. Domestic modified asphalt coatings are mainly solvent-based and water-emulsion modified asphalt waterproof coatings. However, because asphalt has the disadvantages of poor flexibility, low elongation, easy cracking at low temperature, especially hot flow and brittleness, the above two modified asphalt coatings have defects in varying degrees during use. Among them, the production method of water-emulsified asph...
