The low-temperature resistant and high impact PVC pipe is prepared by the following raw materials by weight: 200 parts of PVC resin powder, 2-3 parts of an organic tin stabilizer, 15-25 parts of light calcium carbonate, 0.5 part of stearic acid, 1-1.9 parts of PE wax, 1.5-4 parts of an impact agent, 3-4 parts of titanium dioxide, 1-4 parts of epoxidized soybean oil, 0.3 part of carbon black and 1 part of aluminium oxide. The PVC pipe obtained by the invention has the characteristics of low-temperature resistance, high strength and high toughness. Product components are cheap and have strong market competitiveness.
Description
Technical field
The present invention relates to plastic pipe technical field, relate in particular to a kind of low temperature resistant high-impact pvc pipe material.
Background technology
Hard polyvinylchloride tubing processed is conventional water delivery tubing, because its tensile strength, compressive strength, flexural strength, the performance such as heat insulation are all better, and price is also cheaper, also there is light weight, bright and clean, attractive in appearance, water resistance is little, assembly is flexible, the features such as time saving and energy saving are installed, and has been subject to users' favor.But in actual use, pvc pipe material firmly processed usually there will be the phenomenon that hydrostatic test and falling weight impact test can not be simultaneously up to standard.Qualified and the drop impact performance inconsistency lattice of the pvc pipe material that most enterprises is produced or pressure-bearing, or drop impact performance is qualified and load performance is defective.Because these two indexs of hard pvc pipe material processed are defective, caused that " booster " phenomenon has appearred in the pvc pipe material using in many water-saving engineerings.The defective tubing that must cause of drop impact of pvc pipe material occurs breaking owing to being subject to the scraped finish of stone sand grains in the process of carrying or in the process of installing, and hydrostatic performance inconsistency lattice cause pvc pipe material because meeting hydraulic pressure, to break when water flowing.In addition, the weathering resistance of tubing is also the problem that enjoys client to pay close attention to, although in standard for the ageing-resistant performance of pvc pipe material is stipulated, in reality follow the tracks of to be used, find, pvc pipe material is used about 2 years laying, and because problem of aging produces, gives a tongue-lashing water phenomenon.
Summary of the invention

The particle diameter of described aluminum oxide is 1000 orders.
The preparation method of a kind of low temperature resistant high-impact pvc pipe material as above, comprises the following steps:
(1) by weigh various raw materials by proportioning;
(2) each component is dropped into the speed with 40 ~ 60rpm in high-speed mixer and stir, obtain compound, set machine barrel Heating temperature and start heating, when described mixture temperature reaches 115 ~ 125 ℃, put into the cold mixed stirrer of low speed with 20 ~ 40 the cold mixed stirring of speed rpm, when the temperature of compound reaches 35 ~ 45 ℃, discharging, and drop in the Double-screw forcing machine of taper, in machine barrel Heating temperature, it is 120 ~ 200 ℃, die temperature is 120 ~ 200 ℃, screw speed is 10 ~ 50rpm, reinforced rotating speed is under the condition of 5 ~ 50rpm, extrude successively according to a conventional method machine-shaping, vacuum sizing, traction, finally be cooled to after room temperature according to required length and cut off the line pipe material enlarging and get final product of going forward side by side.
The present invention compared with prior art has the following advantages:
1, polyvinyl chloride resin powder of the present invention adopts SG-5 type, therefore, has strengthened the resistance to low temperature of pvc pipe material.
2, the present invention adds anti-impact agent in pvc pipe material, improves the low temperature brittleness of macromolecular material, can effectively improve the shock resistance of tubing, gives the toughness that tubing is higher.
3, the present invention adds aluminum oxide to be used for improving the thermal conductivity of pvc pipe material in pvc pipe material, thereby improves pvc pipe material ageing-resistant performance, improves the quality of pvc pipe material.
4, through reality test, the feature (referring to table 1) that the pvc pipe material of gained of the present invention has is low temperature resistant, high strength and high tenacity are laid equal stress on, product component is cheap and the market competitiveness is large.
