Description
Technical field
The present invention relates to a kind of rubber pipe and production technology thereof, particularly a kind of fibre wound coreless rubber pipe and production technology thereof.
Background technique
At present China's method of producing spiral rubber hose has been the core method or core centreless and usage has been arranged, and it is to adopt the soft core of rubber to make mould that the core method is arranged, in carrying out glue extrude, semi-cure, through fiber winding, sheath hose outer and vulcanization process, make finished product.This method also needs the demoulding to remove the flexible glue core.Two during the last ten years the most of producers of China adopt this kind method always.The major defect of this method is, complex procedures, and equipment needed thereby is many, and labor strength is big, the cost of production height, energy consumption is big.Employed flexible glue core generally can only use about 10 times just to be scrapped, and wastes greatlyyer, and the glue core is easily pulled apart during the demoulding, causes substandard products or waste product.Therefore, some producers are to some small-bore sebific ducts in recent years, as Φ 6mm～10mm, adopt the centreless method to produce, and promptly without the flexible glue core, directly extrude, twine, sulfuration and make finished product, but the circularity of sebific duct, the adhesion inequality of fiber.And to larger caliber, as the sebific duct of Φ 10mm～30mm still with there being the core method to produce.Number of patent application is 88105007, and denomination of invention discloses a kind of manufacturing process of fibre wound coreless rubber pipe for the Chinese patent application of " a kind of manufacturing process of fibre wound coreless rubber pipe ".This technological process is: with behind the sizing material heat refining of working good → through extruder extrude inner glue layer → send into carry out in the sulfurizing pot semi-cure → carrying out fiber twine in kiss-coating starch → send drying room drying → through T type extruder head sheath hose outer → send in the sulfurizing pot once more and vulcanize, it is characterized in that: a, before entering sulfurizing pot once more charges into the air of 1～8kg/cm ↑ (2) pressure in spiral rubber hose.B, in the shutoff of the two ends of the sebific duct that charges into air, and seal, with the holding tube internal pressure with clamping element.Its deficiency is: production technology is complicated, cost height, technological operation inconvenience.
Summary of the invention
The objective of the invention is to be included in the design in the sizing compound formula for a kind of novel Coreless Twining Rubber Pipe And Its Preparation Method is provided.Sebific duct directly carries out fibre threads and twines after extruder is extruded hose lining, need not to be coated with kiss-coating slurry and drying process, and wrap wire and hose lining are directly bonding.After T type extruder is extruded outer layer glue, at pan vulcanization.Adopt the bursting pressure 〉=3.0Mpa of the sebific duct of novel centreless winding method production, internal diameter is φ 5～30mm.
Purpose of the present invention can take following method to realize:
A kind of Corelesss winding hose, pipe rubber layer in comprising, crust rubber layer and manage fibre threads enhancement layer between rubber layer and the crust rubber layer described in is characterized in that:
