Abstract
The invention provides a modified asphalt interface adhesive and a preparation method thereof. The preparation raw materials of the modified asphalt interface adhesive comprise the following components; wherein the component A is prepared from asphalt, rheological rubber, a tackifier, rare earthpowder, an antioxidant and an ultravioletlight absorber; preferably, the preparation raw materials comprise the following components in parts by mass: 15 to 25 parts of asphalt, 30 to 45 parts of rheological rubber, 30 to 45 parts of tackifier, 0.5 to 1 part of rare earthpowder, 0.5 to 1 part of antioxidant and 0.5 to 1 part of ultravioletlight absorber. The modified asphalt interface adhesive is high in bonding strength, has good water resistance, weather resistance and acid and alkali resistance, can automatically repair waterproof layer damage and the like caused by infirm bonding and external force influence, and ensures good bonding performance in a humid environment and a low-temperature environment.
Description
technical field [0001] The invention belongs to the technical field of waterproof materials, and in particular relates to a modified asphalt interface adhesive and a preparation method thereof. Background technique [0002] At present, domestic asphalt waterproofing membranes are roughly divided into two types: modified asphalt waterproofing membranes and self-adhesive waterproofing membranes, which have a history of many years. Modified asphalt waterproofing membrane and self-adhesive waterproofing membrane have problems such as poor adhesion to the base surface and water channeling during construction, resulting in damage to the waterproof layer. Bond repair. However, the current existing asphalt interface adhesives have low bonding strength with cement dry base or wet base, poor water resistance, weather resistance, acid and alkali resistance, and repair problems still exist after bonding in humid environment and low temperature environment. Firm, waterproof layer damag...
