Abstract
The invention discloses a macromolecule sealing material for equipment leaking stoppage with temperature and pressure and a preparation method of the macromolecule sealing material. The macromolecule sealing material comprises the following raw materials in parts by mass: 70 parts of polytetrafluoroethylene, 10 pars of graphite, 10 parts of silica, 4 parts of ethylene glycol, 4 parts of glycerin and 2 parts of rare earth nano material. Compared with the welding technology, the macromolecule sealing material has the advantages that the leaking stoppage is successfully performed and the operation can be carried out on the premise of no halt, and economic loss of enterprises caused by accidents are reduced; and compared with other macromolecule sealing materials for pipeline leaking stoppage with temperature and pressure, the macromolecule sealing material has the characteristics of long duration, good leaking stoppage effect and easy disassembly.
Description
Technical field
The present invention relates to high molecule sealing materials, specifically, is a kind of high molecule sealing materials be used to be installed with standby leak stopping with the temperate zone and preparation method thereof.
Background technology
The high molecule sealing materials of existing leak stopping is a lot, but normally is used for the leak stopping of normal temperature and pressure, for being with warm equipment with pressure, usually equipment need to be shut down, and carries out at normal temperatures and pressures leak stopping, thus very inconvenient, and increase maintenance cost.
Summary of the invention
Technical problem to be solved by this invention is that a kind of high molecule sealing materials be used to be installed with standby leak stopping with the temperate zone and preparation method thereof is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of high molecule sealing materials be used to be installed with standby leak stopping with the temperate zone and preparation method thereof is comprised of the raw material of following mass fraction: 70 parts of tetrafluoroethylene, 10 parts in graphite, 0 part of silica 1,4 parts of ethylene glycol, 4 parts of glycerol, 2 parts of rare earth nano materials.
The above-mentioned preparation method who is used for being installed with the temperate zone high molecule sealing materials of standby leak stopping comprises the following steps:
(1) the tetrafluoroethylene extended band is broken, be fibrous;
(2) be 70 parts of fibrous tetrafluoroethylene extended bands after getting 10 parts in graphite, 0 part of silica 1,4 parts of ethylene glycol, 4 parts of glycerol, 2 parts of rare earth nano materials, fragmentation by the quality proportioning of raw material, send in the stirrer and stir the mixture of formation mud shape;
(3) check, packing, warehouse-in.
The invention has the beneficial effects as follows:
(1) compare with welding technique, can be under the prerequisite of not stopping operation and shutoff success, the financial loss that the reduction accident is brought to enterprise.
(2) press leak stopping specialty high molecule sealing materials to compare with other pipeline band temperate zones, possess the plugging effect longer duration, easily detachable characteristics.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail:
High molecule sealing materials be used to be installed with standby leak stopping with the temperate zone of the present invention is comprised of the raw material of following mass fraction: 70 parts of tetrafluoroethylene, 10 parts in graphite, 0 part of silica 1,4 parts of ethylene glycol, 4 parts of glycerol, 2 parts of rare earth nano materials.
The preparation method comprises the following steps: (1), the tetrafluoroethylene extended band is broken to be fibrous; (2), be 70 kilograms of fibrous tetrafluoroethylene extended bands after getting 10 kilograms in graphite, 0 kilogram of silica 1,4 kilograms of ethylene glycol, 4 kilograms of glycerol, 2 kilograms of rare earth nano materials, fragmentation by the proportioning of raw material, send in the stirrer and stir the mixture of formation mud shape; (3), check, packing, warehouse-in.
In the high molecule sealing materials pharmaceutical formulation, add an amount of rare earth nano material, with its dimensional effect and chemically reactive, sulfidation is not fully exerted component property, makes it produce higher cross-linking density, it is mobile to have improved injection technique, strengthens preparation to the adaptability of different working conditions.
High molecule sealing materials of the present invention has good medium-resistance, next swelling for different media, erosion, dissolving etc.All processes can accomplish not produce any spark when using high molecule sealing materials of the present invention to stop a leak, and does not need to get angry, and guarantees safety.Structure is detachable, does not destroy original sealed structure.
The present invention can in the sealed structure that the equipment leakage position rebulids, transmit extruding and contact not lay-by temperate zone means of press seals operation of reality with leaking medium.Can satisfy the shutoff operation under the different condition, product can satisfied temperature from-180 ℃ to 900 ℃ various dielectric leakages sealings.In the product application process, by the integrated use to multi-subject knowledges such as mechanics, materialogy, hydraulic technique, rheologys, in the situation that does not affect the normal operation of equipment, the effectively leakage of the media such as prevention equipment generation fluid, gas, can under the condition that the maintenance facilities safety and steady is produced, satisfy the needs that rear emergency first-aid repair occurs accident.Product is mainly used in the pipeline of the Process Industries such as oil, chemical industry, chemical fertilizer, metallurgy, medicine, chemical fibre, coal gas, water supply, heat supply.
Above-described embodiment only is used for illustrating technological thought of the present invention and characteristics, its purpose is to make those skilled in the art can understand content of the present invention and implements according to this, can not only limit claim of the present invention with present embodiment, be equal variation or the modification that all disclosed spirit is done, still drop in the claim of the present invention.
