Description
Technical field
The invention belongs to hydraulic rubber technical field of hoses, more particularly to a kind of enhanced hydraulic rubber flexible pipe with protective case.
Background technology
With expanding economy, industry is more and more flourishing, hydraulic rubber flexible pipe can be all used in many equipment, machine more particularly with diesel oil as the energy, during using these machines, due to the high temperature and corrosive nature of diesel oil, the sebific duct of general material is by after prolonged fuel feeding, the failures such as corrosion leakage can occur, the use of machine is influenceed.
The structure of hydralic hose is mainly made up of the synthetic rubber outer glue-line of the synthetic rubber inner glue layer of resistant to liquid, mesoglea, multilayer enhancement layer, resistance to weather；Hydralic hose presses material and is divided to quality of rubber materials and the major class of rubber and plastic material two；By production technology point wire braided hose, wire spirally-wound hose, line braided construction hose and fabric hose etc..
The outer glue-line of hydralic hose is mainly synthetic rubber, there are problems that it is not ageing-resistant, be easily cracked, no.If hydralic hose unprotect overcoat, directly contacts when using with environment, the hydralic hose for especially being used in engineering machinery; it is chronically exposed under sun direct projection; receive ultraviolet and ozone aging, and often with the debris friction such as sandstone, easily cause hydralic hose outer glue-line damaged.Sebific duct outer layer is mostly using water cloth vulcanization is twined, and there is woven design on sebific duct surface, unsightly, and is easily polluted by dust, not easy to clean；Most traditional sheath molding mode to be wound on tank body by hand after independent extrusion spiral sheath, but this artificial mode cost of labor for wearing sheath is high, and efficiency is low and length and shape of to tubing have certain requirement, and thickness is thicker, and the cost of raw material is higher.
The content of the invention
The present invention makes up the deficiencies in the prior art, there is provided a kind of enhanced hydraulic rubber flexible pipe with protective case aiming above mentioned problem；The present invention not only has the advantages that oil resistant, heat-resisting, toughness are strong etc., and the present invention realizes the preparation of hydraulic rubber flexible pipe using expressing technique, and saving raw material improve production efficiency, saved cost of labor.
To realize above-mentioned purpose of the invention, the present invention uses technical scheme as follows.
A kind of enhanced hydraulic rubber flexible pipe with protective case; including the resistance to oil reservoir, refractory layer, fiber braiding layer, steel wire braid, the outer compound protective layer that set gradually from inside to outside, linked together using extrusion vulcanization between the steel wire braid and outer compound protective layer；Linked together using extrusion vulcanization between the outer wall of the refractory layer and the inwall of fiber braiding layer.
Used as a preferred embodiment of the present invention, the mass ratio between the fiber braiding layer and steel wire braid is 2:3.
Used as another preferred scheme of the invention, the resistance to oil reservoir is made using fluorubber with polysulfide rubber.
Used as another preferred scheme of the invention, the refractory layer is made using chlorohydrin rubber with lactoprene.
Further, the thickness of the resistance to oil reservoir is 2~3mm, and the thickness of the refractory layer is 2.5~3mm.
Used as another preferred scheme of the invention, the fiber braiding layer is 5~6mm with the thickness of steel wire braid.
Used as another preferred scheme of the invention, using the one kind in silicon rubber, butadiene rubber and isoprene rubber, the thickness of the outer compound protective layer is 5.5~6.5mm to the outer compound protective layer.
Beneficial effects of the present invention compared with prior art.
A kind of enhanced hydraulic rubber flexible pipe with protective case that the present invention is provided; the fluorubber and polysulfide rubber used by resistance to oil reservoir; the chlorohydrin rubber that refractory layer is used and polyacrylate rubber; and the fiber braiding layer with good toughness is made with steel wire braid, have the advantages that oil resistant, heat-resisting, toughness are strong etc.；The present invention realizes the preparation of hydraulic rubber flexible pipe using expressing technique, saves raw material, improves production efficiency, has saved cost of labor.
