Waterproof coiled material with sterilizing effect and preparation method thereof

Abstract

The invention discloses a waterproof coiled material with bactericidal effect and a preparation method, belonging to the technical field of waterproof coiled materials. The waterproof coiled material comprises a base layer, a first bactericidal layer arranged on the upper surface of the base layer and a first waterproof layer arranged on the lower surface of the base layer, the upper surface of the first sterilizing layer is provided with a second waterproof layer, and the second waterproof layer is arranged on the upper surface of the base layer. A protective layer is provided on the upper surface of the layer, a second bactericidal layer is provided on the lower surface of the first waterproof layer, and a PE protective layer is provided on the surface of the second bactericidal layer. Wherein, the first and second waterproof layers are both SBS modified asphalt self-adhesive waterproof layers, and the first and second bactericidal layers are both TiO2 / graphene modified polyurethane nano-bactericidal coatings. The waterproof coiled material can effectively avoid the growth of bacteria on the waterproof coiled material, and has a good bactericidal effect, and the preparation method has simple process, mild conditions and good application prospects.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material, in particular to a waterproof coiled material with bactericidal effect 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 p...

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.

In addition, since the construction of the waterproof membrane uses adhesives to bond the waterproof membrane, there are many disadvantages, which will not only pollute the environment, but also due to the limited strength of the waterproof layer and anti-aging sheath of the ordinary polymer waterproof material, the long-term It is easy to breed bacteria, the service life is low, and the waterproof performance is not ideal. Therefore, the bactericidal performance is also one of the urgently needed performances of waterproof membranes.
