Problems solved by technology

Although the waterproof rain cloth can have better anti-aging shape and certain cohesiveness, because the adhesive layer is tape-like, it cannot realize the performance of long-term bonding, and then cannot achieve the effect of long-term waterproofing, and further research is needed.

Abstract

The invention discloses a waterproof rain cloth and a preparation method thereof, belonging to the technical field of waterproof materials. The waterproof rain cloth includes a base layer, which is a non-woven fabric layer, and also includes a waterproof coating arranged on the upper surface of the base layer, and an elastic waterproof layer arranged on the lower surface of the base layer, and the elastic waterproof layer and The base layers are connected by a bonding layer. Wherein, the waterproof coating is a graphene-modified polyurethane coating, the elastic waterproof layer is a titanium dioxide / natural rubber nanocomposite material layer, and the adhesive layer is a graphene-modified epoxy resin adhesive layer. The preparation method comprises: preparation of graphene-modified polyurethane paint; preparation of titanium dioxide / natural rubber nanocomposite material; preparation of graphene-modified epoxy resin binder; preparation of waterproof rain cloth. The waterproof rain cloth not only has a good waterproof effect, but also has high toughness and elasticity. The preparation method is simple in process, mild in conditions, and has good application prospects.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to a waterproof rain cloth and a preparation method. 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] With the development of buildings, people have put forward higher requirements for the quality of the building of the living room and the waterproof and leakproof of the construction project. For example, in the existing external wall door and window project, the gap b...
