Abstract
The present invention relates to an atactic copolymerization polypropylene aluminum plastic composite pipe. An outer layer is made from atactic copolymerization polypropylene PP-R or block copolymerization polypropylene. An inner layer is made from the atactic copolymerization polypropylene PP-R or the block copolymerization polypropylene. A middle layer is made of an aluminum material. Polypropylene hot-melt adhesive is added between the outer layer and the middle layer. The polypropylene hot-melt adhesive is added between the inner layer and the middle layer. The weight percentage of the materials used by the atactic copolymerization polypropylene aluminum plastic composite pipe is 10 to 40% of inner layer polypropylene, 40 to 70% of outer layer polypropylene, 10 to 40% of middle layer aluminum material and 0.5 to 15% of aluminum-plastic hot-melt adhesive. The present invention has the advantages of easy producing process, easy production and no need of special equipment addition. The atactic copolymerization polypropylene aluminum plastic composite pipe has the advantages of a common PP-R pipe and a common aluminum-plastic compound pipe, and simultaneously, also overcomes the disadvantages of the low strength of the common PP-R pipe, the no hot melt connection of the common aluminum-plastic compound pipe, etc. The atactic copolymerization polypropylene aluminum plastic composite pipe can be widely applied to various fields to replace metal pipes, and has large social and economic benefits.
Description
Technical field:
The present invention relates to PAP, a kind of atactic copolymerized polypropylene aluminium composite pipe and preparation method thereof is provided especially.
Background technology:
PAP is owing to have plastic pipe anticorrosive property and the high advantage of metal pipe material 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 multiple tube, adopt pipe fitting to connect between the tube and tube, the leakage problems of junction is the greatest problem during PAP is used all the time, 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, PAP has the advantage of plastic pipe and metal pipe material concurrently, but the PAP 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, form by five layers, skin is atactic copolymerized polypropene PP-R or block copolymerization polypropylene, internal layer is atactic copolymerized polypropene PP-R or block copolymerization polypropylene, the intermediate layer is an aluminium material, dose the polypropylene thermal melten gel between skin and the aluminium lamination, dose the polypropylene thermal melten gel between internal layer and the aluminium lamination, the percentage by weight of the used material of multiple tube is:
Internal layer polypropylene 10-40%
Outer polypropylene 40-70%
Middle aluminium material layer 10-40%
PUR 0.5-15% between plastic-aluminum
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.
In the atactic copolymerized polypropylene aluminium composite pipe of the present invention, used PUR is acrylic acid or maleic anhydride modified polypropylene.
The present invention also provides the preparation method of above-mentioned atactic copolymerized polypropylene aluminium composite pipe, adopt overlap welding formula PAP extruder to form the PAP of producing plastic layer, it is characterized in that preparation process is: on the production line, after the aluminium strip uncoiling moulding, the inner plastic layer extruder is extruded the atactic copolymerized polypropene inner plastic layer, interior adhesive linkage extruder extrudes acrylic acid or maleic anhydride modified polypropylene thermal melten gel at inner plastic layer pipe outer wall, aluminium strip wraps on the internal plastic tube that scribbles acrylic acid or maleic anhydride modified polypropylene thermal melten gel, 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, extrude by the outer plastic layer extruder simultaneously and contain the atactic copolymerized polypropene plastic layer, processing temperature is between 190-240 ℃, and extruded velocity is that the PAP that 8-10 rice part will be contained atactic copolymerized polypropene at last cools off by tank, cutting, the packing back becomes finished product.
Manufacturing process of the present invention is simple, produces easily, need not to increase special installation, and the tubing of production is except that the advantage that has common PP-R pipe and PAP 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 material to have very big social benefit and economic benefit.
