Description
Technical field
The present invention relates to a kind of a kind of high durable protective materials for aerial pipeline of outdoor aerial pipeline field application
And preparation method thereof.
Background technique
In the modern life and production process, pipeline is used widely as a kind of delivery means, can convey water,
Natural gas, oil product and a variety of chemical mediators, and pipeline corrosion protection is the important means for guaranteeing pipeline and running steadily in the long term.According to application
The characteristics of environment, aerial pipeline because being exposed in atmospheric environment for a long time, since ultraviolet light is strong, cause pipeline atmosphere thermo-oxidative ageing and
Ozone aging is violent.In the environment over strait that borders on the sea, tide may be also faced with and splashed and high sea salt environment, the weatherability of material is special
It is UV resistant and ozone ability is the emphasis that design of material must be taken into consideration.
Traditional aerial steel pipe carries out external anti-corrosion in such a way that multilayer epoxy anticorrosive paint forms composite armor.
However epoxy molecule main chain contains benzene ring structure, is easy to absorb ultraviolet light and aging dusting occurs, it is final to lose anti-corrosion and protection function
Energy.On the other hand, the anti-corrosion effect of epoxy-based lacquers and brushing thickness and film curing degree are closely related, under normal circumstances, anti-corrosion
Layer, which needs repeatedly to brush can be only achieved, requires thickness, and construction period is longer and film curing state is inconsistent, leads to anti-corrosion effect
It is unstable.
Another main corrosion-inhibiting coating of steel pipe is 3PE, and cladding material is mainly polyethylene.Polyethylene ultraviolet light,
It is easy degradation dusting under ozonization, protection is caused to fail, anti-corrosion failure.
Summary of the invention
The technical problem to be solved by the present invention is to provide the one of a kind of weather-proof antiseptic property for effectively improving outdoor aerial pipeline
Kind is used for the high durable protective materials of aerial pipeline.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of high durable protective materials for aerial pipeline, including outer layer and internal layer, the outer layer are functional weather-proof
Protective layer, the material of the outer layer are chlorosulfonated polyethylene backing, the internal layer for realizing, sealing bonding with pipeline and
Antisepsis, the material of the internal layer are butyl rubber base waterproof gasket cement；
The chlorosulfonated polyethylene backing by mass fraction include: chlorosulfonated polyethylene be 100 parts, polyethylene be 50~
125 parts, ethylene-vinyl acetate copolymer is 5~15 parts, and titanium dioxide is 3~15 parts, and magnesia is 2~15 parts, and light stabilizer is
0.1~0.3 part, antioxidant is 0.1~0.6 part, and rubber antiager RD is 0.5~2.0 part, and kaolin is 10~55 parts, season penta
Tetrol is 1~4 part, and promotor is 1~3 part；
The butyl rubber base waterproof gasket cement by mass fraction include: butyl rubber be 100 parts, polyisobutene be 10~
40 parts, naphthenic oil is 5~15 parts, and C5 Petropols are 25~45 parts, and zinc oxide is 0.5~2 part, alkyl phenolic resin 0.5
~5 parts, rubber antiager RD is 0.5~2 part, and carbon black is 0.5~5 part.
The present invention includes internal layer and outer layer double-layer structure, carries out the production of protective materials first in use, is guaranteed
The protection effect up to standard of protective materials.Then protective materials can be realized bonding with pipeline by internal layer, simplify protection behaviour
Make step, improves the operation up to standard of pipeline protection efficiency and protection.The material is resistance to using chlorosulfonated polyethylene as backing simultaneously
Time property is excellent, effectively increases pipeline protection effect, ensure that the normal service life of aerial pipeline, matches resource rationally
It sets.
Further, the light stabilizer is 770 stabilizers.
