Abstract
The invention discloses a high-pressure-resistant HDPE (high-density polyethylene) water supply pipe material, which is prepared from the following raw materials in parts by weight: 80-120 parts of HDPE, 10-30 parts of modifier, 5-15 parts of fire retardant, 2-10 parts of metal oxide and 5-15 parts of white carbon black. A HDPE water supply pipe made by adopting special material disclosed by the invention has good high-pressure-resistant property and anti-impact property, is good in moulding effect and has no pollution and low energy consumption during production.
Description
Technical field
The invention belongs to vinyon tubing technical field, be specifically related to a kind of HDPE water service pipe material.
Background technology
Compare with traditional metal tube, cement pipe, plastic pipe has the advantages such as quality is light, corrosion-resistant, flow resistance is little, synthesis energy saving good, easy transportation and installation, long service life.The material that plastic pipe uses mainly contains PVC, PE and polypropylene etc.Compare with other plastics tubing, high density polyethylene(HDPE) (HDPE) tubing has that density is low, good toughness, corrosion-resistant, good insulation preformance, be easy to the advantages such as construction and installation, is widely used in the fields such as building water supply and drainage, combustion gas, heat supply heating, electric wire threading, agricultural water-saving irrigation of having stable political situation, city.
HDPE tubing can be divided into penstock and non-pressure pipe by Application Areas, and wherein penstock comprises gas line, indoor and outdoor water service pipe and sandwich tube.At present, the engineerings such as the water supply in cities and towns, sea water desaltination adopt HDPE tubing more and more.Along with improving constantly of city tap-water popularity rate, will be increasing to the demand of HDPE water-feeding pipes with good high voltage performance.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of HDPE water service pipe material with good high voltage performance and flame retardant properties is provided, also provide this HDPE water-feeding pipes preparation method for material simultaneously, the method production cost is low, and environmental pollution is little.
Above-mentioned purpose of the present invention is achieved by the following scheme:
A kind of high pressure resistant HDPE water service pipe material, its raw material by following weight parts is made: HDPE80～120 part, 10～30 parts of properties-correcting agent, 5～15 parts of fire retardants, 2～10 parts of metal oxides, 5～15 parts of white carbon blacks.
For further improving the product performance of HDPE water service pipe material, to count by weight percentage, the combinatorial optimization of raw material is: HDPE100 part, 20 parts of properties-correcting agent, 10 parts of fire retardants, 4 parts of metal oxides, 10 parts of white carbon blacks.
Above-mentioned properties-correcting agent is chloride 20% CPE.
Above-mentioned fire retardant is comprised of main flame retardant and auxiliary fire retardant, and wherein main flame retardant is Sb
2O
3, auxiliary fire retardant is zinc borate, the weight ratio of main flame retardant and auxiliary fire retardant is 10: 1～5: 1.
Above-mentioned metal oxide is selected from one or both among MgO or the CaO.
Above-mentioned White Carbon black particle diameter is 800～2000 orders.
A kind of preparation method of product of high pressure resistant HDPE water service pipe material is as follows:
(1) preparation raw material
Put into mixer after taking by weighing various raw material pulverizing according to needed weight part, mixer is heated to 40 ℃～50 ℃, adopt 540～600 rev/mins rotating speed to stir 60～70 seconds, stirring mixes, then continue mixer is heated, at this moment, adopt 1000 rev/mins rotating speed to stir, until the temperature of mixer reaches 120 ℃～130 ℃;
(2) extrusion profile
The raw material that mixes is sucked in the loading hopper of screw machine, extrusion profile with bonding jumper, is provided with fin at this bonding jumper in a side of this section bar, has the groove with this fin coupling at the cavity interval of the opposite side that is positioned at described section bar body;
(3) make plastic section bar spiral winding pipe
With the section bar spiral winding of extruding, described fin is snapped in the described groove;
(4) repair and make finished product
To make the polishing of plastic section bar spiral winding pipe edge, make finished product.
Compared with prior art, the beneficial effect that the present invention has is: the HDPE water service pipe that adopts PP Pipe Compound of the present invention to make has good high voltage performance and shock resistance, and good forming effect, and is pollution-free during production, energy consumption is low.Simultaneously, the HDPE water service pipe flame retardant effect that adopts PP Pipe Compound of the present invention to make is obvious.
