Description
Technical field
The present invention relates to a kind of stationary seal ring material.
Background technology
Ship is a kind of composite with stern shaft seal static ring material, is mainly used in screw shaft of ship sealing.Due to the material
Need to use in water for a long time, water absorption rate, expansion rate of water absorption are had higher requirements, and the material is by friction effect,
Need that there is good anti-wear performance and intensity.The wear-resisting of material is mainly increased by calcium carbonate in the existing composite
Performance is wiped, but calcium carbonate is unfavorable for the reduction of stationary ring and rotating ring frictional force, causes the rotary power of rotating ring to increase, power consumption；Separately
Outside, existing stationary ring can also increase the certain water absorption rate of material by nylon fiber, but whole fibre strength is relatively low.
The content of the invention
For in place of above-mentioned the deficiencies in the prior art, the present invention solve the problems, such as be：It is small, wear-resisting to provide a kind of frictional force
Wipe, the stationary seal ring material that intensity is high.
To solve the above problems, the technical scheme that the present invention takes is as follows：
A kind of stationary seal ring material, including phenolic resin, reinforcing fiber, filler；Described reinforcing fiber include nylon fiber and
Glass fibre；Described nylon fiber and glass fibre, which are twisted together, to be formed；Described filler include crystal whisker of gypsum, polytetrafluoroethylene (PTFE),
Alundum (Al2O3)；Described phenolic resin and the mass ratio of filler are 1：2~1：3.
Further, the line footpath of described nylon fiber and glass fibre is 0.2~0.3mm.
Further, described reinforcing fiber includes two strands of nylon fibers and one glass fibre.
Further, the mass ratio of the crystal whisker of gypsum in described filler and polytetrafluoroethylene (PTFE) is 2：1~3：1；Described fills out
The mass ratio of alundum (Al2O3) and polytetrafluoroethylene (PTFE) in material is 1：2~1：3.
Further, the draw ratio of described crystal whisker of gypsum is 1nm.
Beneficial effects of the present invention
The reinforcing fiber of the present invention by nylon fiber and glass fibre be twisted together and formed, and nylon fiber can strengthen water suction
Rate, glass fibre can strengthen intensity and corrosion resistance, be had complementary advantages by nylon and the twisted of glass fibre；In addition,
The filler of the present invention includes crystal whisker of gypsum, polytetrafluoroethylene (PTFE), alundum (Al2O3), in being used as by the alundum (Al2O3) of porosity characteristic
Between medium crystal whisker of gypsum and polytetrafluoroethylene (PTFE) are sufficiently mixed, polytetrafluoroethylene (PTFE) has certain lubricant effect, abrasion-resistant
Effect is fabulous；Crystal whisker of gypsum has fixed shape of cross section, complete profile, perfect internal structure, has strong well
Degree, and friction sealed effect is good；So the sealing of whole product is enhanced by the cooperation of crystal whisker of gypsum and polytetrafluoroethylene (PTFE)
Anti-wear performance and intensity.
