Abstract
The invention provides a polyvinyl chloride/nitrile rubber alloy special material. The material is prepared by the following steps: adopting an advanced production technology, taking polyvinyl chloride as the basic material, mixing nitrile rubber into polyvinyl chloride according to a certain ratio, adding auxiliary agents such as cold-resistant plasticizer, stabilizing agent, anti-aging agent, and the like, and finally subjecting the mixture to a special treatment so as to make into granules. Because nitrile rubber is added, the prepared polyvinyl chloride-nitrile composite plastic has the characteristic of rubber flexibility (thermoplastic elastomer); at the same time, because rubber has an excellent oil resistant property and can be used as a macromolecular plasticizer, the polyvinyl chloride-nitrile composite plastic has the advantages of oil resistance, cold resistance, solvent resistance and mobility resistance, can be used to manufacture motor cables, various kinds of oil-resistant wires and mobility-resistant wires, and the like; and is especially suitable for being used under low-temperature environment.
Description
Technical field
The present invention relates to polymer modification technology, especially polyvinyl chloride/nitrile-butadiene rubber alloy PP Pipe Compound.
Background technology
Polyvinyl chloride (PVC) starting material wide material sources, goods cost is low, quality is light, construction and maintaining convenient, be to occupy second general-purpose plastics.But PVC material has the shortcoming such as poor toughness, poor heat resistance, restrict its development in the higher field of performance requriements.
For many years, people have obtained larger progress at aspects such as PVC Blending Toughening Modifications.Wherein NBR (butadiene-acrylonitrile random copolymers also claims paracril) is because of good with PVC consistency, and the toughness of material, the oil-proofness that obtain are excellent and gain great popularity, and rubber plastic blend formula therefore how to seek a kind of economical and efficient is real in necessary.
Summary of the invention
The invention provides polyvinyl chloride/nitrile-butadiene rubber alloy PP Pipe Compound, it is take polyvinyl chloride as base-material, mixes a certain proportion of paracril, and adds the auxiliary agents such as cold resistant plasticizer, stablizer, protective agent, through the special pellet of being processed into.First add high-speed mixer high speed to mix the polyvinyl chloride measuring and nitrile rubber, in the time that temperature rises to 145 ℃, stop mixing; After again the auxiliary agents such as the softening agent measuring, stablizer, protective agent being put into high-speed mixer high speed mix in the time that temperature being down to 125 ℃, through twin screw extruder extruding pelletization.This product is owing to there being the use of mixing of paracril, and product has the flexibility (thermoplastic elastomer) of rubber.Because rubber has good oil resistance, and the effect of tool macromole softening agent, therefore this product has good oil resistant, cold-resistant, resistance to solvent and resistance to migration.For as motor lead and all kinds of oil resistant electric wires, the electric wire of resistance to migration etc., be particularly useful for low temperature resistant environment.
