Description
One, technical field
The present invention relates to a kind of pipeline anti-corrosive paint, exactly is a kind of coal mine gas pipe alloy anticorrosive composite coating.
Two, background technology
Methane gas is one of principal element of harm coal mine production safety, and the extraction of methane gas is most important in the Coal Production.At present, the gas drainage pipe in the colliery divides nonmetal pipeline and steel pipe.Nonmetal pipeline mainly comprises Glass Steel Tube, polyvinyl chloride (PVC) pipe, polyethylene (PE) pipe.There are shortcomings such as fragility is big, shock resistance difference in Glass Steel Tube, and the pressure-bearing of polyvinyl chloride (PVC) pipe, polyethylene (PE) pipe is not strong, and ageing-resistant performance is relatively poor.Therefore, the gas drainage pipe in the colliery is a steel pipe mostly at present, but there was dampness in the air under the coal mine, there are inflammable easily sudden and violent dust and gas, various corrosive gases and liquid, steel pipe is perishable, need carry out rotproofing to steel conduit, to improve its work-ing life and safety.
In steel tube surface plastic-coated or coating is a kind of effective way of colliery with steel pipe corrosion-proof, has overcome the defective of easily the getting rusty of steel pipe itself existence, burn into high pollution.Patent CN201028165 discloses a kind of underground mine use polymer steel-plastic composite pressure pipe, is provided with the corrosion protection coating that high-molecular polythene or epoxy are made at stainless steel tube or weldless steel tube tube wall.Patent CN200993270 discloses the steel-plastics composite pipe of a kind of mine, oil field use, is coated with the polypropylene corrosion-resistant coating at metal body inner-wall surface.CN201014071 discloses a kind of underground mine use polyethylene coating composite steel tube, is compounded with the anti-electrostatic flame-retardant polyvinyl coating in the inner and outer circumferential surfaces of steel pipe.CN201225492 discloses a kind of mining steel pipe that has aliphatics polyureas coating, utilizes aliphatics polyureas coating that the steel pipe inside and outside wall is covered.These bibliographical informations colliery steel pipe corrosion-proof technology, but the high molecule plastic shock-resistance of steel-plastics composite pipe is not high, come off easily after being impacted in the transportation installation work, and the corrosion resistance nature of single corrosion protection coatings such as epoxy, aliphatics polyureas often can not satisfy the requirement for anticorrosion of gas drainage pipe.
Three, summary of the invention
The present invention aims to provide a kind of long-life coal mine gas pipe, and technical problem to be solved is that the inside and outside wall at gas pipe imposes compound coating, and this coating had both had strong adhesion, shock resistance, had antistatic, fire-retardant and non-corrosibility again.
Thinking of the present invention is to be superposeed regularly by ultra-fine squamous zinc powder and aluminium powder in steel tube surface to form, with the mineral compound is binding agent, stick to the metallic surface, behind sintering, form splendid aluminium zinc chrome (alloy) coating of one deck protection against corrosion impact resistance, antistatic at its surface-coated one deck then, fire retardant, anticorrosive coating form the alloy anticorrosive composite coating.
Gas pipe alloy anticorrosive composite coating of the present invention is composited by aluminium zinc-chromium coating I and flame-retardant and anti-static corrosion protection coating II.The coating of coating I by A, B component by 1: the 1.0-2.0 mass ratio mixes, and disperses, is sprayed on that sintering forms coating I on the tube wall through physics.
The A component comprises each component of following weight part:
The B component comprises each component of following weight part:
