Abstract

The invention relates to the construction material field, in particular to a waterproof asphalt sealing material used outdoor, and provides a waterproof asphalt sealing material which can be used outdoor and has the properties of being waterproof, corrosion resistance and ageing resistance and has the component and weight percentage: 40 to 70 of asphalt, 14 to 20 of naphthenic oil, 4 to 12 of SBS, 5 to 10 of xylene, 5 to 10 of turpentine, 1 to 7 of zinc oxide, 0.1 to 1 of 2, 4-dihydroxybenzophenone, 0.05 to 3 of 4, 4'-thiobis(2, 6-di-tert-butylphenol), 0.1 to 1 of 4-benzoyloxy-2, 2, 6, 6-tetramethylpiperidine, and marginal water. By adopting the technical proposal, the waterproof asphalt sealing material can remain paste shape in normal temperature, can be used by opening the tank at any time, can be covered on the surface of a building or solidified after gapping, and can experience being waterproof, light resistance, corrosion resistance for more than 20 years, is resistant in water, cold, and high temperature, and can achieve good waterproof and sealing effect.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a waterproof asphalt sealing material used outdoors. Background technique [0002] At present, the waterproofing of buildings, such as gaps in bridges, gaps in steel structures, buildings, etc., generally use waterproof membranes. However, the use of waterproof membranes generally requires the surface of the laying to be treated, such as leveling, cleaning, and primer application. If the sealing degree is high, other liquid sealing materials should be used to seal the edge of the coil. In short, the use of membranes does not completely solve the problem of waterproof sealing. Especially in some extreme conditions, such as dryness, deserts with large temperature differences, humidity, etc., it is more difficult to find suitable sealing and waterproof materials that can resist aging for a long time. Contents of the invention [0003] The object of the present invention is to ...
