Abstract
The invention relates to a sealing strip capable of resisting high-temperature high-pressure water vapor, which is prepared from the following raw materials in parts by weight: 100 parts of ethylene propylene diene monomer 301T, 1-3 parts of anti-aging agent RD, 50-70 parts of carbon black N660, 45-60 parts of spray carbon black, 4-10 parts of dioctyl phthalate, 0.4-1 part of cross-linking assistant TAIC and 3-5 parts of dioctyl phthalate peroxide. The invention has the following advantages: 1) on the premise of not influencing the properties of the sealing strip, the low-cost raw materials are adopted; 2) the sealing strip has favorable the compressive deformation property, the shape can not change severely under the working conditions of high temperature and high pressure, and the 125 DEG C*70H permanent compressive deformation is less than 8%; 3) the sealing strip can be well applicable to sealing of high-temperature high-pressure water vapor, and can resist a high temperature of 160 DEG C; and when the amount of precompression of the O ring is 0.8mm, the high-pressure chamber can reliably implement 60mpa sealing.
Description
Technical field
The present invention relates to a kind of sealed strip, especially relate to a kind of sealed strip of high temperature high voltage resistant water vapour.
Background technology
Present sealed strip all can not reach the requirement of operating mode in tensile strength at yield, tensile yield, tear strength, compression set, and especially its above-mentioned defective is more obvious under the water vapour situation of sealing HTHP.
Summary of the invention
First technical problem that the present invention will solve provides a kind of sealed strip of high temperature high voltage resistant water vapour; The sealing bar adopts low-cost raw material under the prerequisite that does not influence performance; The pressure sex change of sealing bar can be better, and under the high temperature and high pressure condition condition, shape can not change too big, can better be applicable to the sealing of high-temperature high-pressure steam.
For solving the problems of the technologies described above, the sealed strip of a kind of high temperature high voltage resistant water vapour of the present invention, form by the raw material of following parts by weight:
100 parts of terpolymer EP rubber 301T, 1～3 part of anti-aging agent RD,
50～70 parts of carbon black N660,45～60 parts of spray carbon blacks,
4～10 parts of DOPs, 0.4～1 part of crosslinking coagent TAIC,
3～5 parts of peroxo-DOPs.
Above-mentioned raw materials is the commodity of selling in the market.
The present invention refines through existing technology and both gets product.
The priced catalogue of above-mentioned raw materials of the present invention: 25 yuan/kg of terpolymer EP rubber 301T; 18 yuan/kg of anti-aging agent RD, 7.5 yuan/kg of carbon black N660,9.3 yuan/kg of spray carbon black; 13 yuan/kg of DOP; 35 yuan/kg of crosslinking coagent TAIC, this prescription cost of manufacture is at 16-18 unit/kg, well below 26 yuan/kg of present market value.
The present invention has following beneficial effect:
1) sealed strip of the present invention adopts low-cost raw material under the prerequisite that does not influence performance, and raw materials cost practices thrift nearly 30%;
2) the pressure sex change of sealed strip of the present invention can be better, and under the high temperature and high pressure condition condition, shape can not change too big, its 125 ℃ of x70H condition lower compression tension sets less than 8%;
3) sealed strip of the present invention can better be applicable to the sealing of high-temperature high-pressure steam, its ability 160 degree high temperature, and when the pre compressed magnitude of O type circle is 0.8mm, hyperbaric chamber can reliably be realized the sealing of 60mpa.
