Description

A kind of polypropylene pipe and preparation method thereof
Technical field
The present invention relates to a kind of tubing, particularly to a kind of polypropylene pipe and preparation method thereof, Belong to pipe technology field.
Background technology
Poly-sustainable development is the target that Present Global is common, reduces the consumption of the energy, protection ring Border, it is to avoid hinder society's normal activity increasingly to come into one's own.Cost at plastic pipe work Expense and energy resource consumption are laid link and usually occupies critical role.The big portion of plastic tube outside building Dividing is buried laying and suspension bracket laying, and traditional suspension bracket is laid, adopted according to designed lines With mechanically or manually operation, suspension and support is installed at the scene, then in suspension and support, installs pipeline also Complete connecting test.
Suspension bracket laying technology proposes new requirement to tubing and material thereof, and suspension bracket is laid and is different from Tradition is laid, and its distinct issues are the problem on deformation of tubing, pipeline in laying due to suspension bracket Being supported by suspension and support, pipeline spot film accepts, the problem installed due to suspension and support, easily makes Pipeline discontinuity, thus be deformed, make pipeline receive damage and concentration may be born Point load.
Summary of the invention
The technical problem to be solved is to provide a kind of hardness good, no for above drawback Yielding polypropylene pipe, and its preparation method is provided.
For solving above-mentioned technical problem, the technical scheme is that
A kind of polypropylene pipe, its constituent is counted as follows by weight:
A kind of polypropylene pipe, it is preferred that its constituent is counted as follows by weight:
A kind of preparation method of polypropylene pipe tubing, its preparation method is as follows:
(1) by anti-ageing to copolymerization grade polypropylene, melamine resin, toughener, plastics Stirring in agent and water addition blender, mixing speed is 650-750 rev/min, stirring 6-10 minute；
(2) mixture in step (1) is added prepared granule in double screw extruder；
(3) granule prepared in step (2) is added poly-third extruded in single screw extrusion machine Alkene tubing germule, the temperature of extruder cylinder of single screw extruder is 125-155 DEG C, and the temperature of mould is 156-175 DEG C, die temperature is 135-145 DEG C；
(4) by nano ceramics powder liquid even application in tubing germule periphery, in temperature Carry out at 95-150 DEG C drying to obtain polypropylene pipe finished product.
Above-mentioned a kind of polypropylene pipe and preparation method thereof, wherein, described toughener is by nanometer One or both compositions in titanium dioxide, ABS resin, polyvinyl alcohol.
Above-mentioned a kind of polypropylene pipe and preparation method thereof, wherein, described nano-ceramic powder liquid The preparation method of body is: is added by nano-ceramic powder in aqueous epoxy resin emulsion, stirs, Its mixing speed is 550-650 rev/min, stirs 5-10 minute, nano-ceramic powder and aqueous The weight ratio of epoxy resin latex is 11-15:100.
The invention have the benefit that the water-tolerant of cymel material, can improve heat-resisting Property and mechanical strength, simultaneously can also improve hardness；Nano ceramics powder liquid can significantly improve Product hardness, hardness is the highest up to 6-8H, owing to its nanometer particle size is the most tiny, therefore Either which kind of solvent is all transparent, plastic anti-aging agent is nonflammable, not burn into storage steady Qualitative good, the compatibility of unsaturated-resin is good, has long-acting antioxygen, yellowing-resistant effect propety concurrently, Increase substantially the ageing resistace of product.The polypropylene pipe gone out by above manufacture of materials is with general Logical polypropylene pipe is compared, and in the case of other performances are constant, its heat distortion temperature can improve 35-40 DEG C, the rigidity of tubing is greatly improved, and its hardness can improve more than 2 times.
Detailed description of the invention
Below by way of specific embodiment, the detailed description of the invention of the present invention is made further details of Explanation.
Melamine resin of the present invention is purchased from the happy safe limited public affairs of chemical industry in Tianjin Development Zone Department；Described nano-ceramic powder is purchased from Shanghai Li Sheng International Trading Company Ltd；Described water-base epoxy Resin emulsion is purchased from Fujian Zhong Ke great achievement Chemical Industry Science Co., Ltd, and described plastic anti-aging agent is purchased In Qingdao Hua En Chemical Co., Ltd..
Example one:
A kind of preparation method of polypropylene pipe, its preparation method is as follows:
(1) toughener is prepared, by nano titanium oxide and ABS resin with the ratio of 1:1.5 Example mix homogeneously；
(2) by the copolymerization grade polypropylene that parts by weight are 100 parts, the tripolycyanamide first of 45 parts Urea formaldehyde, 10 parts of toughener, 12 parts of plastic anti-aging agents and 80 parts of water addition blenders stir Mixing uniformly, mixing speed is 650 revs/min, stirs 10 minutes；
(3) mixture in step (2) is added prepared granule in double screw extruder；
(4) granule prepared in step (3) is added poly-third extruded in single screw extrusion machine Alkene tubing germule, the temperature of extruder cylinder of single screw extruder is 135 DEG C, and the temperature of mould is 165 DEG C, die temperature is 145 DEG C；
(5) prepare nano ceramics powder liquid, nano-ceramic powder is added aqueous epoxy resins breast In liquid, stirring, its mixing speed is 550-650 rev/min, stirs 5-10 minute, Nano-ceramic powder is 15:100 with the weight ratio of aqueous epoxy resin emulsion；
(6) by nano ceramics powder liquid even application that parts by weight are 22 parts at tubing germule Periphery, carries out drying to obtain polypropylene pipe finished product at temperature 120 DEG C.
Example two:
A kind of preparation method of polypropylene pipe, its preparation method is as follows:
(1) toughener is prepared, by nano titanium oxide and polyvinyl alcohol with the ratio of 1.2:1 Mix homogeneously；
(2) by the copolymerization grade polypropylene that parts by weight are 100 parts, the tripolycyanamide first of 30 parts Urea formaldehyde, 8 parts of toughener, 10 parts of plastic anti-aging agents and 65 parts of water addition blenders stir Mixing uniformly, mixing speed is 650 revs/min, stirs 10 minutes；
