Abstract
A composite atactic copolypropylene-aluminium pipe is composed of internal plastic layer (polyethylene), internal adhesive layer (maleic acid) anhydride grafted polyethylene as thermosol), aluminium layer, external adhesive layer (acrylic acid or maleic acid, anhydride modified polypropylene as thermosol), and external plastic layer (atactic or block copolypropylene plastics). Its advantages are simple proparing process, high strength and hot fusible joint.
Description
Technical field:
The present invention relates to aluminium-plastic composite pipe, a kind of atactic copolymerized polypropylene aluminium composite pipe and preparation method thereof is provided especially.
Background technique:
Aluminium-plastic composite pipe is owing to have plastic tube anticorrosive property and the high advantage of metal pipe intensity concurrently, and is widely used in various fields such as building, petrochemical industry.The aluminum current plastic composite is generally the polyethylene aluminium plastic composite pipe, adopt pipe fitting to connect between the tube and tube, the leakage problems of joint is the greatest problem during aluminium-plastic composite pipe is used all the time, in order to prevent that the pipe fitting design of various structures from having appearred in seepage, but leakage problems never can fundamentally solve.Common atactic copolymerized polypropene PP-R pipe has good antiseptic property, and can carry out the hot melt connection, but because intensity is low, has also limited it and both required intensity at some, the surrounding medium application in the place of more complicated again simultaneously.In general, aluminium-plastic composite pipe has the advantage of plastic tube and metal pipe concurrently, but the aluminium-plastic composite pipe that contains atactic copolymerized polypropene does not appear in the newspapers so far.
Summary of the invention:
The invention provides a kind of atactic copolymerized polypropylene aluminium composite pipe, by inner plastic layer, interior adhesive layer, aluminium lamination, outer adhesive layer, outer plastic layer is superimposed constitutes, it is characterized in that: it is outer to be atactic copolymerized polypropene or block copolymerization polypropylene plastics, outer adhesive layer is acrylic acid or maleic anhydride modified polypropylene thermal colloidal sol, interior adhesive layer is the polyethylene thermosol of modified by maleic acid anhydride graft, internal layer is a polyethylene, and used material of composite pipe and weight percentage are:
Outer polypropylene 40-70%
Inner layer polyethylene 10-40%
Middle aluminium layer 10-40%
Outer adhesive layer polypropylene thermal colloidal sol 0.5-10%
Interior adhesive layer polyethylene thermosol 0.5-10%.
In the atactic copolymerized polypropylene aluminium composite pipe of the present invention, used polyethylene is high density polyethylene (HDPE), medium density polyethylene, LLDPE.
In the atactic copolymerized polypropylene aluminium composite pipe of the present invention, the aluminum used matter layer aluminium strip trade mark is 8011A, 8001,1145,1235,1100,1200,1050,1060, the high-grade soft aluminium of state O or H22, annealing degrease.
The present invention also provides the preparation method of above-mentioned atactic copolymerized polypropylene aluminium composite pipe, manufacturing equipment adopts lap welding formula aluminium-plastic composite pipe to extrude unit, it is characterized in that preparation process is: on the production line, after the aluminium strip uncoiling moulding, inner plastic layer extruder polyethylene extrusion plastic layer, interior adhesive layer extruder extrudes the modified by maleic acid anhydride graft polyethylene hot-melt adhesive at inner plastic layer pipe outer wall, aluminium strip wraps on the polyethylene hot-melt adhesive internal plastic tube that scribbles modified by maleic acid anhydride graft, with ultrasonic welding machine continuously after lap-joint welding, coat outer acrylic acid or maleic anhydride modified polypropylene thermal melten gel by the outer layer glue extruder again, processing temperature is between 190-240 ℃, extrude atactic copolymerized polypropene PP-R plastic layer by the outer plastic layer extruder simultaneously, processing temperature is between 190-240 ℃, extruded velocity 8-10 rice/minute, will contain atactic copolymerized polypropene PP-R modification aluminium-plastic composite pipe at last and cool off by tank, cutting, the packing back becomes finished product.
Advantage of the present invention is that manufacturing process is simple, produces easily, need not to increase special equipment, and it is except that the advantage that has common PP-R pipe and aluminium-plastic composite pipe concurrently, and also having solved common PP-R simultaneously, to manage intensity low, the conventional aluminium plastic composite can not the hot melt connection etc. shortcoming.Can be widely used in various fields, replace metal pipe to have very big social benefit and economic benefit.
