Abstract
The invention discloses a sealant, aims to provide the sealant with wide temperature resistance range, high tensile strength, good injection manufacturability, good filling quality and sealing effect. The sealant comprises the following compositions by weight portion: 20 portions of nitrile rubber, 6 portions of semi reinforcing carbon black, 14 portions of iron oxide red, 18 portions of talcum powder, 2 portions of rare-earth nanometer material, 15 portions of dioctyl ester, 5 portions of diantimony trioxide, 5 portions of chlorcosane, 3.5 portions of zinc oxide, 2 portions of stearic acid, 1.5 portions of accelerating agent CI, 3 portions of antioxidant A, and 5 portions of wire. By selection of a base material and various accessory ingredients as well as the exertion of component performance, the sealant improves the cross-linking density in sulfidation process, improves physical mechanical performance, has wide temperature resistance range and high tensile strength, and widens the application field. The sealant has excellent process flowability and mouldability at beginning stage of injection, can be easily filled in each position of a sealing cavity, avoids generation of a dead angle, has good filling quality, and ensures long-term stability of the sealing effect.
Description
Technical field
The present invention relates to a kind of sealing agent, in particular, relate to a kind of sealing agent that under the pressure sealing environment, uses.
Background technology
In industrial production,, need to use sealing agent outside band temperature, band are pressed to, under the spray regime leakage point to be carried out sealing and plugging when valve, when pipeline takes place to leak.In order to adapt to different working mediums and environment, it is ZL00129800.3 that our company has developed the patent No., and denomination of invention is the sealing and plugging product of " sealing agent ", and it can adapt to different media, can obtain good effect.Along with the raising of country's big-and-middle-sized flow process business equipment turnover rate, the variation that varies is also taking place in working condition.For the variation of adaptation condition condition, the temperature resistant range of sealing agent and density, tension are torn intensity and had higher requirement, to guarantee the success ratio of all flow process enterprise operations.
Summary of the invention
The present invention is in order to overcome weak point of the prior art, to provide a kind of temperature resistant range wide, and tension is torn the intensity height, and injection technique is good, the sealing agent of filling quality and good sealing effect.
The present invention is achieved through the following technical solutions:
A kind of sealing agent is characterized in that, is made up of following component by weight: 20 parts of paracrils, 6 parts of semi-reinforcing hydrocarbon blacks, 14 parts of red iron oxides, 18 parts of talcum powder, 2 parts of rare earth nano materials, 15 parts of dioctyl esters, 5 parts of antimonous oxides, 5 parts of clorafins, 3.5 parts in zinc oxide, 2 parts of stearic acid, accelerant C I1.5 part, 3 parts of antioxidant As, 5 parts in wire.
Wherein, wire is the fine copper silk, and length is 15mm, and diameter is 0.3mm-0.5mm, is extruded out-of-shape with other components.
Described rare earth nano material is neodymium (Nd).
The present invention has following technique effect:
1. the present invention has done best configuration according to the characteristics of body material to vulcanization system.Make temperature resistant range reach-195
-900 ℃.The present invention makes sealing agent have good heat resistance, the vulcanization system of selecting the low-sulfur height to help raise efficiency, condition with the performance of adaptive zone means of press seals injecting whole process technology efficiency, make sealing agent of the present invention possess good preservation, and the process flowability of in the injecting process, bringing into play and mold and satisfy the tensile strength of technical requirements, make sealing agent after injection initial stage, mistake are moulded process and be converted into elastomerics, set up effective sealed structure.
2. in the prescription of the present invention, adding wiry is under the scope situation for Applicable media system temperature, pressure broad, and, can prevent from that anchor clamps from coincideing to implement under the overproof condition in gap that wire plays barrier effect, prevents that sealing agent is extruded.Material wiry, diameter, suitable length injecting advance, and prevent the stifled injection gun outlet of card.
The present invention by screening fill, supporting material, make sealing agent of the present invention fill the annular seal space process, can bear leaking medium rush to summit and finish injecting after set up enough bearing capacities.
4. added rare earth nano material in the prescription of the present invention, utilized the activity of the little and rare earth element of nano-grain particle diameter, component property is not fully exerted, the heatproof of sealing agent of the present invention, media-resistant and mechanical property have had tangible improvement.Because the dimensional effect of nano material, be beneficial to and overcome the space body resistance, produce good dispersion and contact effect; The active chemical property of rare earth element, promote the cross-linking effect of sulfidation, make the higher cross-linking density of generation in the sealant structure of the present invention, strengthen and suppress the molecular conformation variation, make structural sheet more stable, heatproof, medium-resistance and physical and mechanical properties are significantly improved.Good through injecting extrusion structure layer compactness, medium is difficult for being penetrated into inside, the part that extexine contacts with medium, formed sane valence link after active group is crosslinked, no longer with medium generation chemical reaction, be difficult for being corroded, to having more tangible adaptability under different media and the special operation condition condition by medium.
5. sealing agent of the present invention passes through the selection of body material and various Synergist S-421 95s and the performance of component property, and temperature resistant range is wide, and density and tension are torn the intensity height, and filling quality is good.The injection initial stage has good process flowability and mouldability, is easy to be filled into each position of annular seal space, avoids producing the dead angle.Along with filling progress, possess stretch-proof, the tearing toughness resisting leaking medium and rush to summit, in case dispel outer spray gradually near the major leak point; After overcompaction and completely solidified, possess certain bearing capacity is arranged, the operating unit sealing load that can remain valid guarantees that all flow process enterprise job success ratios reach 100%.
