The invention relates to a
flame retardant and antistatic steel mesh skeleton
polyethylene composite
pipe for mining and a manufacturing method thereof. The method is characterized in that the
polyethylene composite
pipe is obtained by the manufacturing processes of subjecting dedicated composite modified
polyethylene plastics to
flame retarding and antistatic treatment in two steps,
compositing the treated plastics with a high-strength steel mesh skeleton and a
hot melt adhesive bond for several times, and heating and vacuuming the composite for several times. At least two
layers of high-strength steel wires are wound to be
reticulate in an oblique crossing manner, arranged between the outer wall of the inner layer and the inner wall of the outer layer as a skeleton, and tightly combined with the
pipe body of the inner and outer
layers into an integral whole by means of a
hot melt adhesive, thus forming a composite pipe for underground
coal mines, which is
flame-retardant and antistatic and has relatively high
mechanical strength and
pressure resistance, long service life and other excellent properties. As the pipes are connected through
welding by electric melting pipe fittings, the flame retardant and antistatic steel mesh skeleton polyethylene composite pipe for mining has high overall properties and convenience in laying, is applicable to the
coal mine industry with strict property requirements in all aspects, and is also applicable to
water supply and drainage,
fire protection and gas delivery in the municipality and construction.
