Technical field
The present invention relates to plastic pipe technical field, specifically a kind of polyvinyl chloride for tubing and polyethylene blend alloy.
Background technology
Along with the continuous propelling of Urbanization Construction, the demand of buried pollution discharge drainage pipe is expanded thereupon.The ring stiffness of polyvinyl chloride blowdown water shoot is better, cheap, but its resistance to impact shock is poor, more responsive to temperature.Polyethylene is that a kind of light weight is nontoxic, and have excellent mechanical property and the thermoplastic material of resistance to chemical corrosion, and it is cheap, resistance to impact shock is good, and forming process is easy.Thus, alloy material polyvinyl chloride and polyethylene blend obtained has good realistic meaning for the preparation of tubing and promotes practical value.
Summary of the invention
The object of the present invention is to provide a kind of polyvinyl chloride for tubing and polyethylene blend alloy, its good combination property, cost is low, and has had polyvinyl chloride and poly advantage well concurrently.
The technical solution adopted for the present invention to solve the technical problems is: a kind of polyvinyl chloride for tubing and polyethylene blend alloy, and its component by mass percent proportioning is: PVC 40% ~ 50%, PE 25% ~ 30%, wollastonite 4% ~ 10%, DOP 6% ~ 9%, ACR 3% ~ 6%, PTW 2% ~ 5%, UV-326 0.5% ~ 2%, calcium-zinc composite stabilizing agent 0.5% ~ 1.5%, EVA wax 0.5% ~ 1%, antioxidant 1010 0.1% ~ 0.5%.
The mean polymerisation degree of described PVC 800 ~ 1200, weight-average molecular weight is in 50000 ~ 120000 scopes.
Described PE is molecular weight 20 ~ 400,000, the low-pressure high-density polyethylene of density 0.95 ~ 0.97g/cm3.
Described wollastonite be surface through silane coupler modified process and diameter 6 ~ 25 μm, length 10 ~ 500 μm, length-to-diameter ratio is at the fibrous wollastonite of 3 ~ 100 scopes.
Described DOP is plasticizer phthalic acid two (2-ethylhexyl ester).
Described PTW is expanding material Ethylene-butyl Acrylate-methacrylic Acid Glycerin Ester Copolymer, and the content of glycidyl methacrylate copolymer accounts for 3wt% ~ 8wt%.
Described UV-326 is photostabilizer 2-(2 '-hydroxyl-3 '-tertiary butyl-5 '-aminomethyl phenyl)-5-chlorinated benzotriazole.
Described antioxidant 1010 is four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester.
The preparation method of above-mentioned a kind of polyvinyl chloride for tubing and polyethylene blend alloy, comprises the following steps:
(1), each component is taken by weight ratio;
(2), PVC, DOP and calcium-zinc composite stabilizing agent are added barrel temperature in the mixing machine of 80 DEG C ~ 90 DEG C, 20 ~ 30min is stirred according to rotating speed 50 ~ 80r//min, add PE, PTW and EVA wax again, stir 10 ~ 20min, then other component is added, stir 10 ~ 30min, after mixing completely, discharging;
(3), by the compound that step (2) obtains add the mixing rear extrusion moulding of twin screw extruder, namely obtain described a kind of polyvinyl chloride for tubing and polyethylene blend alloy.
The invention has the beneficial effects as follows, the present invention combines polyvinyl chloride and polyethylene original advantage separately, and overcome the deficiency that both one-components exist, but also significantly improve mechanical property, ageing-resistant performance and processing characteristics etc., its cost is low, wide accommodation.
