Abstract
The utility model provides a polyurethane waterproof coating, including substrate layer, anti -corrosion coating, waterproof layer, the surface is equipped with anti -corrosion coating about the substrate layer, the anti -corrosion coating surface is connected with the waterproof layer, wherein, the substrate layer is the non -woven fabrics layer, anti -corrosion coating is graphite alkene epoxy resin coating, the waterproof layer is the polyurethane waterproof layer. Polyurethane waterproof coating, adopt graphite alkene epoxy resin coating as anti -corrosion coating because graphite alkene has lamella conjugated structure, the compact isolation layer of stack formation can effectively restrain infiltration and the infiltration of water to filming layer upon layer, plays the physics preservation, the electric conductive property of graphite alkene makes its and metal form the electrolytic bath for the metal loses the electron and to the coating surface, prevents the emergence of corroding. Waterproof coating, the bindability is good between each layer, and preparation technology is simple, is fit for the industrial production, has higher using value.
Description
Technical field
This utility model is related to a kind of polyurethane waterproof coating.
Background technology
Waterproof material is widely used in various industry and the roofing of civil buildings, the engineering waterproofing of basement, and subway,
In the engineering waterproofing of the municipal administration such as tunnel, highway bridge and water conservancy projects, current waterproof roll collapse resistance power is poor, easily occurs puncturing
Or tear phenomenon, need labor intensive, material resources to be repaired, shorten the service life of waterproof material, cause resource and fund
Waste.
Existing waterproof roll is water-repellent paint of coating outside paper tire, and its toughness, cracking resistance are poor, sealer with
Between matrix, bonding force is poor, and service life is short, is susceptible to seepage accident.Though also having some rubber and EPDM waterproof rolled sheet
Good water-proof effect, but expensive, it is unsuitable for industrial applications.
Polyurethane water-proof paint has the title of " liquid rubber ", is one of best water-repellent paint of current combination property, can use
Waterproof, seepage control in long-term position of soaking.This material is thought of as waterproof membrane by reacting fixed line after brushing at the construction field (site), is a kind of
, easily there is became uneven, steal in long-life waterproofing process, but the restriction because of job site operating procedure, monitoring means itself
The problems such as work material reducing, it is used alone the query easily receiving from customer, monitoring party.
The Chinese patent application of Publication No. cn203766159u provides a kind of polyurethane coating film waterproof roll, this volume
Material passes through to increase fiberglass reinforced aluminium foil and dual-component polyurethane film layer on asphaltic base waterproof layer top, bottom increases self-adhesive layer and
Isolating membrane forms a kind of multi-layer compound structure to lift its performance.This coiled material increased on the basis of asphaltic base waterproof layer
Four layers of construction, complex manufacturing, though can make moderate progress in material performance itself, its construction reliability is to be carried by essence
Rise.
The Chinese patent application of Publication No. cn204183986u provides a kind of anti-corrosion waterproof roll of polyurethane coating film, this
Plant coiled material and be provided with mono-component polyurethane film layer, mono-component polyurethane film layer and high molecular sheet in macromolecule waterproof lamella both sides
It is provided with enhancement layer it is adaptable to some occasions to waterproof material occasion serious corrosion, such as refuse landfill, dirt between material layer
Water treatment plant etc..This coiled material both sides mono-component polyurethane film layer is not formed there through entirety it is impossible to realize its package action, with
The risk of separation failure after long-term use is deposited between enhancement layer, macromolecular sheet material layer.
Therefore, find a kind of cohesive good, the not only polyurethane coating film of waterproof but also antiseptical excellent combination property, have important
Meaning, be also research emphasis be located.
Utility model content
For defect of the prior art, the purpose of this utility model is to provide a kind of polyurethane waterproof coating, Neng Gou great
Big raising water resistance and anticorrosive, anti-permeability performance, and cost is relatively low, suitable industrialized production.
This utility model solves technical problem and adopts the following technical scheme that
This utility model is related to a kind of polyurethane waterproof coating, including substrate layer, corrosion-resistant coating, waterproof layer, described base material
Layer upper and lower surface is provided with corrosion-resistant coating, and described corrosion-resistant coating outer surface is connected with waterproof layer.
Preferably, described substrate layer is nonwoven layer.
Preferably, described corrosion-resistant coating is Graphene epoxy coating.
Preferably, described waterproof layer is polyurethane water-proof layer.
Compared with prior art, this utility model has a following beneficial effect:
A kind of polyurethane waterproof coating described in the utility model, using Graphene epoxy coating as anticorrosion
Layer, because Graphene has lamella conjugated structure, is layering and forms fine and close isolation layer, can effectively suppress water to film
Infiltration and infiltration, play physical preservation effect；The electric conductivity of Graphene makes itself and metal form electrolyzer so that metal loses
Electronics, to coating surface, stops the generation of corrosion.Described waterproof coating, between each layer, cohesive is good, preparation process is simple, is suitable for
Industrialized production, has higher using value.
Brief description
By reading detailed description non-limiting example made with reference to the following drawings, of the present utility model other special
Levy, objects and advantages will become more apparent upon:
Fig. 1 is the structural representation of polyurethane waterproof coating described in the utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, this utility model is expanded on further.These embodiments are merely to illustrate this
Utility model rather than restriction scope of the present utility model.
As shown in figure 1, a kind of polyurethane waterproof coating of this utility model preferred embodiment, including substrate layer 1, anticorrosion
Layer 2, waterproof layer 3, described substrate layer 1 upper and lower surface is provided with corrosion-resistant coating 2, and described corrosion-resistant coating 2 outer surface is with waterproof layer 3 even
Connect.Wherein, described substrate layer 1 is nonwoven layer, and described corrosion layer 2 is Graphene epoxy coating, and described waterproof layer 3 is poly-
Urethane waterproof layer.
Polyurethane waterproof coating described in the utility model, using Graphene epoxy coating as corrosion-resistant coating, by
In Graphene, there is lamella conjugated structure, be layering and form fine and close isolation layer, can effectively suppress the infiltration to film for the water
With infiltration, play physical preservation effect；The electric conductivity of Graphene makes itself and metal form electrolyzer so that metal loses electronics
To coating surface, stop the generation of corrosion.Described waterproof coating, between each layer, cohesive is good, preparation process is simple, is suitable for industry
Metaplasia is produced, and has higher using value.
Above specific embodiment of the utility model is described.It is to be appreciated that this utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can make various modifications or modification within the scope of the claims,
This has no effect on flesh and blood of the present utility model.
