Embodiment 1

[0022] The release paper is kraft paper coated with silicone oil on both sides, the thickness is 0.08mm, and the butyl rubber is butyl sealant with a shear strength of 0.10MPa and a thickness of 1mm (MF2000M butyl sealant, Zhengzhou Zhongyuan Applied Technology Research and Development Co., Ltd.) , the aluminum foil layer is selected 0.06mm aluminum foil, rolled together to form butyl tape, silicone glue (MF965F silicone anti-corrosion sealant, Zhengzhou Zhongyuan Applied Technology Research and Development Co., Ltd.), the two form the anti-corrosion composite material of the present invention.

Embodiment 2

[0024] When the anticorrosion composite material in Example 1 is in use, first clean up the surface of the concrete or steel structure, then tear off the release paper of the butyl tape, stick the butyl adhesive with aluminum foil on the surface of the steel structure or concrete, and build The joint width is not less than 20mm to form a fully covered state. Then, put the silicone glue in a spray gun and spray it on the surface of the aluminum foil to form a silicone glue layer with a thickness of about 1 mm. After the silicone glue is cured, the anti-corrosion coating of the present invention is obtained. Such as figure 1 As shown, the anti-corrosion coating sequentially includes a butyl rubber layer 1 , an aluminum foil layer 2 and a silicone glue 3 .

Abstract

The invention provides an anticorrosion composite material. The anticorrosion composite material is used for steel structures or concrete structures and comprises a butyl rubber tape and silicone adhesive. The silicone adhesive is used for being coated on the surface of the butyl rubber tape. The invention further provides an anticorrosion coating. The anticorrosion composite material and the anticorrosion coating have the advantages that the anticorrosion composite material can be applied to realizing anticorrosion effects for the steel structures or the concrete structures, accordingly, destruction due to external corrosive media can be prevented, and the steel structures and the concrete structures can be effectively protected; the anticorrosion coating can be formed on the steel structures or the concrete structures by the anticorrosion composite material and is good in sealing performance, and accordingly the steel structures and the concrete structures can be effectively protected against corrosion; the anticorrosion composite material and the anticorrosion coating are excellent in weather resistance and difficult to age or fail or fall off, and simple, convenient and attractive construction effects can be realized.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion materials, in particular to an anti-corrosion composite material and the obtained anti-corrosion coating. Background technique [0002] At present, the method of "surface derusting + painting" is often used for anticorrosion of steel structures. This method is cumbersome to construct, and the anticorrosion effect is not optimistic. Under natural aging conditions, the spray paint often falls off. Concrete is a porous structure, and it is prone to cracks and spalling under the action of water, oxygen or corrosive gases. From the concrete structure painting practice in our country, the system of "epoxy sealer + epoxy miracic iron intermediate paint + acrylic polyurethane topcoat" occupies a dominant position. This system has complex construction and high requirements for workers, and it is difficult to cope with the freeze-thaw cycle in the alpine region, so it also has certain disadvantages....
