Non-cured asphalt mastic

Abstract

The invention requests to protect non-cured asphalt mastic comprising the following components in percentage by weight: 35-55 asphalt, 15-30 naphthenic oil, 3-10 polymer modifying agent, 55-20 gelatin powder, 3-10 diisononyl phthalate and 10-20 tackifying resin. The non-cured asphalt mastic can be independently used or can be used with the matched coil to form a waterproof system and can effectively solve the problem of water leakage caused by the crack of a waterproof layer due to the deformation of a base layer.

Description

Technical field: [0001] The invention relates to a non-curing asphalt glue, in particular to a non-curing rubber asphalt glue used in waterproof engineering of building structures. Background technique: [0002] Due to its mature technology, high level of industrialization, stable performance, convenient construction and simple maintenance of equipment, bitumen waterproofing membrane is widely used in domestic and foreign construction. Asphalt waterproof membrane (referred to as asphalt membrane) is a layer of waterproof layer laid on the surface of the building, or between the building base and the decorative surface. An important technical means of service life. Asphalt waterproofing membrane is widely used in industrial and civil buildings at home and abroad because of its simple structure, less maintenance workload, long service life, and long-term waterproofing effect in one construction. Although the existing asphalt waterproofing membrane also has a certain degree o...

AI Technical Summary

Problems solved by technology

Although the existing asphalt waterproofing membranes also have a certain degree of elongation, when there are cracks in the base of the building or deformation of the building structure, it is still easy to cause the waterproof layer to crack.

Moreover, in areas with complex structures, it is difficult to achieve full stickiness, which leads to the phenomenon of water stringing
