Embodiment 1

[0010] Anti-corrosion fillers include thickeners and inert inorganic fillers added to liquid rubber, which are clay-like anti-corrosion fillers.

[0011] In weight percent, polyisoprene 14%, polyalphaolefin 5%, antioxidant 1%, organic bentonite 5%, aluminum hydroxide 44%, calcium carbonate 31%. Described antioxidant is antioxidant 565 (commercially available product)

Embodiment 2

[0013] Anti-corrosion fillers include thickeners and inert inorganic fillers added to liquid rubber, which are clay-like anti-corrosion fillers.

[0014] In weight percent, polyisoprene 16%, polyalphaolefin 4%, antioxidant 1%, organic bentonite 3%, aluminum hydroxide 43%, calcium carbonate 33%. Described antioxidant is antioxidant 565 (commercially available product)

[0015] The anti-corrosion filler obtained in the above-mentioned embodiment 1 and embodiment 2 has the same effect. The hardness change is small at low temperature and high temperature, and the workability is excellent; it does not drip at high temperature, and the molding state is good; it is also flame retardant. It is suitable for the filling and molding of various special-shaped pipelines, protruding edges, grooves, gaps, valves and other special parts and objects with complex shapes. It is also a good auxiliary material for anti-corrosion tapes when pasting and winding.

Abstract

The invention relates to an anti-corrosion filling material, and in particular relates to an oxidative polymerization type anti-corrosion filling material. The anti-corrosion filling material is a clayey anti-corrosion filling material which is formed by adding liquid rubber into a thickener and an inert inorganic filler. Compared with petrolatum, the anti-corrosion filling material is narrow in hardness change range at low temperature and high temperature and high in operability, does not drip at the high temperature, is in a good molding state, and is flame-retardant. The oxidative polymerization type anti-corrosion filling material is applicable to filling molding of special parts and objects in a complex shape structure such as various specially-shaped pipelines, nibs, grooves, gaps and valves, and is a good auxiliary material for an anti-corrosion adhesive tape during adhesion and winding.

Description

technical field [0001] The invention relates to an anti-corrosion filler, in particular to an oxidation-polymerization type anti-corrosion filler. Background technique [0002] Steel structures such as Binhai Power Plant, mechanical equipment, and storage tanks exposed to the outdoors are severely corroded. In order to ensure its safe operation and save resources, it is necessary to formulate targeted anti-corrosion countermeasures. The anti-corrosion methods used in the past, such as coating anti-corrosion paint, anti-corrosion paste, metal spraying, epoxy coating, cement coating, anti-corrosion tape and other coating methods, are suitable for various special-shaped pipelines, protruding edges, grooves, and gaps , Valves and other special parts and objects with complex shapes and structures, even if more anti-corrosion materials are added, it is difficult to match the protected object, the sealing is limited, the shape is not good, the cost is high, the anti-corrosion effe...
