The present invention discloses a kind of preparation method of high abrasion scratch resistance polypropylene pipe.Include following components in percentage by weight: PP resin 70 ~ 85%, calcium sulfate crystal whiskers 8 ~ 20%, silicone powder 1 ~ 3%, aluminium oxide 2 ~ 8%, fluorine-containing auxiliary agent 0.1 ~ 3%, antioxidant 0.1 ~ 0.5%.Polypropylene pipe of the present invention has the characteristics that high abrasion scratch resistance and excellent in mechanical performance, while extrusion pressure when can reduce processing, reduces energy consumption, eliminates melt fracture, improves the processing performance of material.
Description
Technical field
The present invention relates to a kind of preparations of high abrasion scratch resistance random copolymerization polypropylene pipe.
Background technique
Polypropylene random copolymer pipe (PPR pipe), have light weight, excellent shock resistance, long-term creep resistance it is good,
Pressure-and heat-resistance, it is resistant to chemical etching the advantages that, be the energy saving and environment friendly plastic pipe of a new generation.But what PPR pipe was used to convey for a long time
When, tube wall can cause scratch, abrasion because of the erosion of fluid, and scratch will lead to stress concentration, and abrasion causes wall thickness thinning,
The mechanical property for thereby reducing tubing makes tubing rupture and leakage.Simultaneously PPR pipe since molecular weight is larger, poor processability,
It is easy to produce melt fracture, " sharkskin " phenomenon occurs；Phenomena such as production efficiency is low, die head buildup.
Fluoropolymer additive is that have extremely low surface energy using fluorine compounds, can be reduced and adds in plastic processing
Interior friction between work molecular resin increases the morphotropism of melting rate and melt, reduces apparent melt viscosity, improves overall plasticizing
Effect.Simultaneously it processing resin in solubility it is lower, incompatible, bath surface is exuded to from melt in process,
Separation layer is formed at resin-equipment interface, reduces the adhesion strength of melt and body, die orifice metal surface, is reduced melt and is being transported
The friction generated during dynamic with wall improves the uneven state of bath movement in process.
Summary of the invention
It is an object of the invention to prepare a kind of high abrasion scratch resistance random copolymerization polypropylene pipe and preparation method thereof, lead to
It crosses and adds the processing performance that a fluorine auxiliary agent improves tubing, reduce extrusion pressure, reduce energy consumption, improve the production effect of tubing
Rate.
To achieve the above object, the technical scheme adopted by the invention is as follows: PP resin 70 ~ 85%, calcium sulfate crystal whiskers 8 ~ 20%, silicon
Ketone powder 1 ~ 3%, aluminium oxide 2 ~ 8%, fluorine-containing auxiliary agent 0.1 ~ 3%, antioxidant 0.1 ~ 0.5%.
Preferably, PP resin 75 ~ 80%, preferably atactic copolymerized polypropene (PPR).
Preferably, antioxidant preferably three [2.4- di-tert-butyl-phenyl] phosphite ester: four [β-(3,5- di-t-butyl -4- hydroxyls
Base phenyl) propionic acid] pentaerythritol ester=1:2.
Preferably, aluminium oxide is α-nano aluminium oxide.
Preferably, fluorine-containing auxiliary agent is fluoroelastomer, and fluoropolymer mass fraction is 99%.
Preferably, the fluorine-containing auxiliary agent is the copolymer of Fluorine containing olefine or the copolymer of fluoroolefin and other alkene.
Preferably, it is extruded as twin-screw extrusion, extrusion process is 160 ~ 170 DEG C of area's temperature, two area's temperature 165 ~ 175
DEG C, three 170 ~ 180 DEG C of area's temperature, four 170 ~ 180 DEG C of area's temperature, five 170 ~ 180 DEG C of area's temperature, 170 ~ 185 DEG C of head temperature, master
300 ~ 450 revs/min of machine revolving speed.
The invention has the benefit that
PPR pipe of the invention has high abrasion scratch resistance, and excellent in mechanical performance, surface is smooth, high production efficiency.It simultaneously can
Extrusion pressure when reducing processing reduces energy consumption, eliminates melt fracture, improves the processing performance of material.
