Abstract
The invention relates to the field of polyethylene pipes and belongs to a polyethylene pipe. According to weight proportion, raw materials are 100 parts of polyethylene resin, 3 to 6 parts of active nanometer calcium carbonate, 2 to 4 parts of polyester of adipic acid, 1,2-propanediol, and 2 to 2.5 parts of black master batch. The polyethylene pipe of the invention uses the active nanometer calcium carbonate with low price as filling materials, thus greatly reducing the production cost of the polyethylene pipe. Compared with a polyethylene pipe without the filing materials, the price of the invention can be reduced by 5 percent, thus enhancing the market competitive of the polyethylene pipe. In addition, the intensity of the polyethylene pipe is strengthened to some extent without reducing the toughness to lead the performance to be more superior, thus broadening the application range of the polyethylene pipe.
Description
One, technical field:
The present invention relates to the polyvinyl piping materials field, is a kind of polyvinyl piping materials.
Two, background technology:
At present, polyethylene tube is one of most popular plastic pipe in the world, also be a kind of tubing that is only second to polyvinyl chloride at home. and the composition major part of polyvinyl piping materials does not have stopping composition. the tenacity excellent of polyethylene tube, shock resistance, nontoxic, but its tube wall is thicker, general under same operating pressure situation, tube wall is 130% of a polyvinyl chloride pipe, price general than with directly with the polyvinyl chloride pipe of pressure expensive 30%.Therefore, in a sense, price factor has influenced a large amount of uses of polyvinyl piping materials.Polyvinyl piping materials toughness is very excellent simultaneously, but insufficient strength has limited its range of application greatly.The purpose that adds stopping composition in the polyethylene tube prescription has two; The one, reduce the polyvinyl piping materials production cost, the 2nd, increase tubing intensity, make it have the advantage of polychloroethylene pipes concurrently, enlarge its use range. but general mineral filler mostly is hydrophilic oleophobic, very poor with the polyethylene consistency, therefore, it also is vital selecting which type of a kind of stopping composition.
Three, summary of the invention:
The invention provides a kind of polyvinyl piping materials, overcome the defective of existing polyvinyl piping materials, not only reduced production cost, and improved intensity.
Technical scheme of the present invention is achieved like this: a kind of polyvinyl piping materials, it consists of the polyvinyl resin of 100 weight parts, the active nano-calcium carbonate of 3 weight part to 6 weight parts, hexanodioic acid 1,2 propylene glycol of 2 weight part to 4 weight parts by parts by weight of raw materials is the black masterbatch of polyester, 2 weight part to 2.5 weight parts.
It is the black masterbatch of polyester, 2.2 weight parts that above-mentioned polyvinyl piping materials becomes the polyvinyl resin of 100 weight parts, the active nano-calcium carbonate of 4.5 weight parts, hexanodioic acid 1,2 propylene glycol of 3 weight parts by the parts by weight of raw materials best group.
The resulting polyvinyl piping materials of the present invention, use the not high active nano-calcium carbonate of price to do stopping composition, greatly reduce the production cost of polyethylene tube, reduce about 5%, increased the market competitiveness of polyethylene tube than the polyvinyl piping materials price that does not add stopping composition.Do not reducing on the polyethylene tube flexible basis, raising to a certain degree the intensity of polyethylene tube, make its performance more superior, thereby enlarge the use range of polyethylene tube.
Five, embodiment:
The present invention is not subjected to the restriction of following embodiment, can determine concrete embodiment according to technical scheme of the present invention and actual needs.
Embodiment 1: it is the black masterbatch of polyester, 2 weight parts that this polyvinyl piping materials consists of the polyvinyl resin of 100 weight parts, the active nano-calcium carbonate of 3 weight parts, hexanodioic acid 1,2 propylene glycol of 3 weight parts by parts by weight of raw materials.
Embodiment 2: it is the black masterbatch of polyester, 2.5 weight parts that this polyvinyl piping materials consists of the polyvinyl resin of 100 weight parts, the active nano-calcium carbonate of 4 weight parts, hexanodioic acid 1,2 propylene glycol of 2 weight parts by parts by weight of raw materials.
Embodiment 3: it is the black masterbatch of polyester, 2 weight parts that this polyvinyl piping materials consists of the polyvinyl resin of 100 weight parts, the active nano-calcium carbonate of 6 weight parts, hexanodioic acid 1,2 propylene glycol of 4 weight parts by parts by weight of raw materials.
The foregoing description 1 to 3 still adopts existing known production polyvinyl piping materials method to obtain needed polyvinyl piping materials, and according to national standard (standard No.: GB/T10002.1-2006) detect, its every performance index are all qualified, and concrete detection method is as follows:
Elongation at break 〉=200% is measured according to GB8804.1～8804.2-88 " thermoplastic plastic pipe Erichsen test method ".
Vertically relaxation shrinkage≤3% is measured according to GB/T6671-2001 " mensuration of the vertical relaxation shrinkage of thermoplastic plastic pipe ".
The sanitation performance index meets GB/T17219-1998 " the safety evaluation standard of Drinking Water transmission ﹠ distribution equipment and protective material ".
Hydrostatic intensity experiment is measured according to GB/T6111-2003 " fluid is carried with thermoplastic plastic pipe internal pressure-resistant experimental technique ".
The filler that uses among the present invention is active nano-calcium carbonate, and common stopping composition is generally hydrophilic oleophobic, and with organic molecule consistency extreme difference, and they self easy reunion forms macromole together.Active nano-calcium carbonate has reached transformation from hydrophilic to lipophilic, has also reduced the reunion between the molecule simultaneously, is a kind of good filler.
The resulting polyvinyl piping materials of the present invention, use the not high active nano-calcium carbonate of price to do stopping composition, use main component to be the elastomeric hexanodioic acid 1 of F simultaneously, 2 propylene glycol are that (resistance is extruded in main reduction to polyester as processing aid, increase the tube surfaces glossiness, simultaneously also can balance increase the energy consumption that stopping composition brings), greatly reduce the production cost of polyethylene tube on the original basis, the polyvinyl piping materials price that does not add stopping composition on year-on-year basis reduces amplitude about 5%, has increased the market competitiveness of polyethylene tube.Simultaneously, active nano-calcium carbonate also plays a kind of effect of toughener, the active nano-calcium carbonate molecule organically combines with the polyethylene molecule, do not reducing on the polyethylene tube flexible basis, the intensity of raising polyethylene tube to a certain degree, make its performance more superior, thereby enlarged the use range of polyethylene tube.
