Anti-aging and water-proof roll and preparation method

Abstract

The invention discloses an anti-aging and water-proof roll and belongs to the field of water-proof rolls. The water-proof roll comprises the following structure: a base material layer, first and second water-proof layers are arranged on upper and lower surfaces of the base material layer respectively, an anti-corrosion layer is also arranged on the upper surface of the first water-proof layer, a first anti-aging layer is arranged on the upper surface of the anti-corrosion layer, and a second anti-aging layer is arranged on the lower surface of the second water-proof layer. The preparation method of the anti-aging and water-proof roll comprises the steps as follows: (1) preparation of self-bonding SBS modified asphalt; (2) preparation of an epoxy resin / graphene nano composite; (3) preparation of a graphene modified polyurethane coating; (4) preparation of the water-proof roll. The water-proof roll has the better water-proof effect, better thermal stability, corrosion resistance and oxidative aging resistance and longer service life, reduces the labor cost and the use cost and has higher application value.

Description

technical field [0001] The invention relates to the field of waterproof coiled materials, in particular to an anti-aging waterproof coiled material and a preparation method thereof. Background technique [0002] Waterproof materials are widely used in the engineering waterproofing of roofs and basements of various industrial and civil buildings, as well as engineering waterproofing of municipal and water conservancy facilities such as subways, tunnels, highway bridges, etc. The current waterproof membranes have poor resistance to damage and are prone to puncture Or tear phenomenon, need to spend manpower, material resources to repair, shorten the service life of waterproof material, cause the waste of resources and funds. [0003] Waterproof membrane is a kind of building material commonly used in building construction. In the construction of road bridges, roofs or buildings that need waterproofing, waterproof membranes need to be laid in advance. At present, the commonly u...

AI Technical Summary

Problems solved by technology

In the application places with high fire protection level requirements, the required waterproof membrane is required to have certain fire and flame retardant properties, while the fire and flame retardant properties of ordinary polymer modified asphalt are poor and cannot meet the requirements for use.

[0004] Waterproof membrane is the first barrier for the waterproofing of the whole project, and it plays a vital role in the whole project. The main products are asphalt waterproof membrane and polymer waterproof membrane. The aging of waterproof membrane has become a problem for the application of waterproof membrane. The biggest threat of the membrane is that the aging of the membrane not only directly leads to a greatly reduced waterproof effect, but also makes the membrane brittle and hard, greatly reducing the value of use

The common manifestations of the aging of waterproof membranes are different degrees of shrinkage, cracking, or shrinkage and decay of the membranes. The aging of the membranes has a major impact on the quality of the project. It will cause adverse effects, and the re-laying of the membrane will cause inconvenience to users. Therefore, trying to reduce the impact of waterproof membranes on aging and slow down the aging speed has become one of the key points of current research on waterproof membranes.

[0005] Although the traditional asphalt waterproofing membrane is low in cost, it has poor tensile strength, low elongation, and poor temperature stability. The short lifespan indirectly increases the user's cost of use
