Problems solved by technology

The coating has high requirements on the surface treatment, at least up to St2.0 level. If the surface treatment of the substrate is not clean, it will lead to poor adhesion performance, and the coating will peel off quickly and fail to play an effective protective role.
But in the valve well, the space is narrow and slippery, the construction work is difficult, and the surface of the valve is irregular, so it is difficult to clean the surface thoroughly
In addition, general anti-corrosion coatings contain a certain amount of volatile solvents. When construction in the valve well, the ventilation conditions are poor, which may easily cause fire and explosion safety hazards, and pose a threat to the health of construction workers.
There are a huge number of metal valves in buried pipelines, which belong to the control equipment for efficient transmission and distribution of the pipeline network. The annual maintenance and management consume a lot of manpower and material resources, but it still cannot effectively solve the corrosion problem

preparation example Construction

[0061] According to another aspect of the present invention, there is provided a method for preparing the flexible anti-corrosion material according to the present invention, comprising the following steps:

[0062] The low melting point component in the flexible anticorrosion material component is melted, mixed uniformly, and added to other components in the flexible anticorrosion material component to obtain the flexible anticorrosion material.

[0063] The low melting point components refer to petrolatum, barium petroleum sulfonate, and chlorinated paraffin.

Embodiment approach

[0064] According to one embodiment of the present invention, the preparation method of flexible anticorrosion material comprises the following steps:

[0065] Weigh vaseline, barium petroleum sulfonate, chlorinated paraffin, antimony oxide, additives, talcum powder, organic bentonite, and foam particles by weight percentage;

[0066] Heating to melt vaseline, barium petroleum sulfonate, and chlorinated paraffin;

[0067] After the vaseline, barium petroleum sulfonate and chlorinated paraffin are completely melted and mixed evenly, cool down slowly;

[0068] Antimony oxides, additives, talcum powder, organic bentonite and foam particles are added to obtain the flexible anticorrosion material.

[0069] According to another embodiment of the present invention, when no flame retardant and additives are included, the preparation method of the flexible anti-corrosion material comprises the following steps:

[0070] Weigh vaseline, barium petroleum sulfonate, talcum powder, organic...

Abstract

The invention relates to the technical field of anti-corrosion materials and in particular relates to a flexible anti-corrosion material, a preparation method and a metal valve. The flexible anti-corrosion material provided by the invention comprises the following components in percentage by weight on the basis of a total weight of the flexible anti-corrosion material: 40-60% of Vaseline, 10-30% of talcum powder, 3-10% of organic bentonite, 3-15% of barium petroleum sulfonate and 1-5% of foamed granules.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion materials, in particular to a flexible anti-corrosion material, a preparation method and a metal valve. Background technique [0002] With the continuous acceleration of China's urbanization process, the demand for natural gas clean energy is increasing. As the main transportation route of natural gas, the number of natural gas pipeline networks has increased sharply, and the coverage has continued to expand. The number of pipelines and pipeline ancillary equipment such as valves is huge, and their safe operation is related to the energy lifeline of the city. [0003] Most of the gas pipelines are laid in the soil, and the valve equipment as key nodes and process control is placed in the underground valve well. The buried pipeline itself has a good coating protection, and combined with the cathodic protection system to form a strict protection system, so that the pipeline itself is protect...
