Description
Technical field
The present invention relates to a kind of tubing polybutene material and preparation method thereof, belong to new type polyolefin Material Field technical field.
Background technology
Polybutene (PB) is a kind of polymer inert polymer, belongs to polyolefins hemicrystalline thermoplastic material.Due to its stability at high temperature and high-flexibility under cryogenic, PB is made to become one of the chemical material of advanced person the most in the world today.The polybutene-1 (iPB) of high isotactic high-crystallinity is called as " gold in plastics ", and having outstanding heat-resisting creep properties, high temperature resistant, environmental stress crack resistance and good toughness, is the best materials as tubing and web member thereof.
The granulating working procedure that has to pass through the iPB powder produced from polymeric kettle changes particle into could keep its satisfactory stability and application performance, is further used as tubing raw material and uses.When preparing polybutene material, for adjusting the performance of material, need to add auxiliary agent in granulation process, the polybutene material prepared is improved in mechanical property, ageing-resistant performance and moulding processability etc.Therefore, the formula developing a kind of new polybutene material extruding pelletization is of great significance for preparing novel tube tool.
Summary of the invention
For above-mentioned prior art, the object of this invention is to provide a kind of tubing polybutene material and preparation method thereof, the proportioning of various adjuvant component by a large amount of optimum experimental, and filter out the iPB powder of suitable melt index, thus prepare the tubing polybutene material of excellent performance.
For achieving the above object, the present invention adopts following technical scheme:
A kind of tubing polybutene material, its raw material consists of:
Polymer resin 100 parts, filler 0.2-10 part, oxidation inhibitor 0.2-5 part, photostabilizer 0.1-3 part, lubricant 0.1-3 part, nucleator 0.05-3 part, look female 1-5 part.

The present invention also provides the preparation method of aforementioned tubes polybutene material, comprising:
(1) above-mentioned each component is mixed;
(2) by the above-mentioned material mixed by twin screw extruder extruding pelletization; Its technique is: a district 150-155 DEG C; Two district 150-155 DEG C; Three district 155-160 DEG C; Four district 155-160 DEG C; Five district 155-160 DEG C; Seven district 160-165 DEG C; Eight district 160-165 DEG C; Nine district 165-170 DEG C; Head 165-170 DEG C; Engine speed 25HZ, feeding rotating speed 5-6HZ, obtain tubing polybutene material.
Above-mentioned polybutene material is also protection scope of the present invention preparing the application in tubing.
Beneficial effect of the present invention:
(1) the tubing polybutene material that prepared by the present invention is obtained for raising in tensile strength, shock strength and flexural strength, PB tubing prepared by it all have passed the internal performance testing standard of tubing enterprise, material has the ageing resistance be close with Basel's material, greatly exceed the working life that tubing prepared by existing polybutene material.
(2) the high-speed molding excellent property of polybutene material of the present invention, the tubing rigidity of preparation, thermotolerance and creep resistant are good, and withstand voltage properties is excellent; Without macroscopic irregularitys such as tiger fur lines, preparation technology is simple, and cost is low.
Accompanying drawing illustrates:
Fig. 1 is that the mode of appearance of the PB particle that Basel prepares with the embodiment of the present invention 1 and comparative example 1 contrasts.Can find out, Basel (in Fig. 1 (a)) and the embodiment of the present invention 1 prepare the form of two kinds of PB particles of (in Fig. 1 (b)), color all relatively, and surface is smoother, fine and smooth, the color of each particle does not have difference; PB particle (in Fig. 1 (C)) form prepared by comparative example 1 is then comparatively large with the above two difference, and surface irregularity.This each component disperses of PB material internal illustrating prepared by the embodiment of the present invention is even, stable.
