Description

The preparation method of 100 grades of orange gas line tag line PP Pipe Compound of a kind of polyethylene
Technical field
The invention belongs to coloring plastic technical field, especially relate to the preparation method of 100 grades of orange gas line tag line PP Pipe Compound of a kind of polyethylene.
Background technology
China starts to produce plastic pipe from 20 century 70s, the beginning of the eighties, starts to apply in engineering construction, and over nearly 30 years, plastic pipe not only quantitatively but also in kind and specification is all greatly developed.Enter 21 century; polyvinyl plastic pipeline development is rapidly unprecedented; in life and industrial application; with its Environmental Safety, more and more favored; bringing into play important, irreplaceable effect, especially in construction industry, plastic pipe in a large number Dai Gang, Dai Mu, for traditional construction material; but also have energy-conservation, material-saving, protection ecological, improve living environment, improve building function and quality, reduce structural weight per square meter, the advantage such as convenient of being completed, be widely used in gas pipeline transportation art.Tubing tag line is as identification tubing purposes and pipe grade, producer often directly adds toner when producing, and can cause very large pollution to production environment like this, and toner is because the form with coacervate exists, cause bad dispersibility, thereby affect the quality of tubing.
Summary of the invention
The object of the invention is: the preparation method that a kind of 100 grades of orange gas line tag line PP Pipe Compound of polyethylene of good dispersity are provided.
Technical scheme of the present invention is: the preparation method of 100 grades of orange gas line tag line PP Pipe Compound of a kind of polyethylene, carries out according to following steps:
(1) pigment of proportioning, lubricant, oxidation inhibitor are added in 5L high-speed mixer, first use stirring at low speed 3 to 6 minutes, then within 25 minutes, make pigment wetted coated by high-speed stirring;
(2) said mixture material transferred in 100L high-speed mixer and add 100 level high-density polyethylene resins, first stirring at low speed 3 to 5 minutes, then high-speed stirring 10 minutes, fully mix material;
(3) compound of step (two) is extruded at the equidirectional parallel double-screw extruder of use temperature 180--240 ℃, through cooling, pelletizing, made PP Pipe Compound;
Above-mentioned composition used is by weight percentage: 100 level high-density polyethylene resins are 95%～96%, lubricant is 0.05%～0.1%, oxidation inhibitor is antioxidant 1010 and irgasfos 168, wherein antioxidant 1010 is 1%～2%, irgasfos 168 is 1%～2%, pigment is orange pigments and titanium dioxide, and wherein orange pigments is 0.6%～1%, titanium dioxide is 0.7%～1%.
Further, lubricant is Zinic stearas.
The invention has the beneficial effects as follows: the pigment of proportioning, lubricant, oxidation inhibitor are added in little high-speed mixer, first stirring at low speed, use again high-speed stirring, make pigment wetted coated after, transfer in large high-speed mixer, and add vector resin-100 level high-density polyethylene resin, first stirring at low speed, high-speed stirring, by equidirectional parallel double-screw extruder extruding pelletization, obtains PP Pipe Compound again.Shearing force by high-speed mixer and equidirectional parallel double-screw extruder is opened pigment agglomerate, and pigment is carried out to Forced Dispersion processing, has improved pigment-dispersing, greatly reduces environmental pollution.By adding a certain amount of oxidation inhibitor, improved the resistance to deterioration of product, stable performance.Antioxidant 1010, chemical name: four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester, can effectively prevent the thermooxidative degradation of polymer materials in long-term aging process, also be a kind of efficient processing stabilizers simultaneously, can improve the discoloration-resistant of polymer materials under high temperature process condition.Irgasfos 168, chemical name: three [2.4-di-tert-butyl-phenyl] phosphorous acid ester is auxiliary antioxidant, composite with primary antioxidant 1010, has good synergistic effect, can effectively prevent the thermal destruction of polyethylene in extruding, gives the extra long-effective protection of polymkeric substance.The present invention's composition proportion used is reasonable, the PP Pipe Compound good dispersity of producing, the PP Pipe Compound production gas line tag line that client can directly use the present invention to prepare, base-material without interpolation oneself, avoided owing to mixing the inhomogeneous aberration causing, this PP Pipe Compound and client tubing base-material used consistency is good, the resistance to migration of pigment, heatproof, have excellent weather resistance, and solve directly use toner produced pollution problem.
