Abstract
The invention relates to a power cable protection pipe. The power cable protection pipe is prepared from the following raw materials in part by weight: 50-85 parts of PP-B, 10-50 parts of PP-R, 5-15 parts of fillers, 0.2-0.25 parts of an antioxidant and 1.5-2.0 parts of color master batch. A preparation method of the power cable protection pipe comprises the steps of stirring and mixing the PP-B, the PP-R, the filler, the antioxidant and the color master batch into a mixer, conveying the mixture into a pipe extruding machine for extrusion, then carrying out vacuum cooling and forming to obtain the product. According to the power cable protection pipe, the PP-B and the PP-R with certain ratio are mixed, then certain parts of the fillers, the antioxidant and the color master batch are added, so that the tensile strength and the welding tensile strength of the obtained pipes after processing are greatly improved, and other mechanical properties are also improved to a certain extent; the technical indexes of the power cable protection pipe are superior to those of the ideal underground trenchless pipes, and the products are difficult to deform after being formed.
Description
Technical field
The present invention relates to a kind of plastic pipe, particularly a kind of power cable protecting pipe.
Background technology
Current power cable protecting pipe tubing is all to use MPP directly to pass through extruder for shaping basically.Owing to there not being the MPP raw material designed for producing MPP electric power protection pipe specially on market, so the electric power protection pipe of producing has a lot of performances not reach standard-required, especially tensile strength and welding tensile strength.And tensile strength and welding tensile strength to be non-excavation buried by of paramount importance performance index in pipe technology, so this class tubing does not reach technical requirements.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of reasonable in design, tensile strength and the large power cable protecting pipe of welding tensile strength.
Technical problem to be solved by this invention is to realize by following technical scheme, the present invention is a kind of power cable protecting pipe, be characterized in: it is to be made by the raw material of following parts by weight: PP-B:50 ~ 85, PP-R:10 ~ 50, weighting agent: 5 ~ 15, oxidation inhibitor: 0.2 ~ 0.25, colour batch: 1.5 ~ 2.0; During preparation, PP-B, PP-R, weighting agent, oxidation inhibitor and colour batch are added in mixer and be uniformly mixed, first under 200 ~ 500r/min speed, stir 2.5-3.5min, stir 1.5-2.5min again under 60 ~ 200r/min speed, after be transported in pipe extruder, through pipe extruder extrude, vacuum cooling typing obtains product.
Technical problem to be solved by this invention can also further realize by following technical scheme, 1, described weighting agent is calcium carbonate;
2, described weight of calcium carbonate umber is 8 ~ 10;
3, the order number of described calcium carbonate >=1200 orders;
4, described oxidation inhibitor is antioxidant 1010;
5, described colour batch is orange or safran colour batch;
6, the parts by weight of described colour batch are 1.5.
The PP-B raw material is block copolymerization polypropylene, and the PP-R raw material is atactic copolymerized polypropene.
The present invention is mixed PP-B according to a certain percentage with PP-R, and PP-B has preferably snappiness but undercapacity, and PP-R has higher intensity but the snappiness deficiency.Bi-material is organically combined can be complementary not enough, thereby the material over-all properties is effectively improved.
Compared with prior art, the present invention mixes PP-B and PP-R according to a certain percentage, the weighting agent, oxidation inhibitor and the colour batch that add certain umber simultaneously, through the resulting tubing of processing treatment, on tensile strength and welding tensile strength, be greatly improved, other mechanical property also obtains certain raising simultaneously, and can surpass the buried technical indicator with pipeline of desirable non-excavation, and its production technique is simple, production cost reduces, product is not yielding after moulding.
