Abstract
The invention relates to a PA66 (polyamide 66) plastic which is prepared from the following components in percentage by weight: 29% of polyphenylether, 29% of nylon 66, 10% of carbon fiber, 8% of glass fiber, 10% of carbon black, 6.5% of compatilizer, 6.5% of toughener and 1.0% of assistant.
Description
Technical field
The invention belongs to polymeric material field, refer to especially a kind of PPO/PA66 synthetic plastics.
Background technology
PPO (polyphenylene oxide) resin and PA66 (nylon 66) resin is one of widely used engineering plastics.PPO has high heat-resisting, dimensional stabilizing, and electric insulating quality is good, but its processing fluidity is poor, not organic solvent-resistant.PA66 belongs to crystalline material, good fluidity, organic solvent-resistant, but its easy suction, poor dimensional stability.
The PPO/PA66 synthetic plastics combines the performance of PPO and PA66, with its excellent thermotolerance, and good processibility, but sprayabilities etc. are used widely.At present, most enhancement type PPO/PA66 synthetic plasticss adopt glass fibre to strengthen, and the density of material that makes is larger, and strength enhancing is inadequate, does not possess antistatic effect.
Summary of the invention
The purpose of this invention is to provide a kind of PPO/PA66 synthetic plastics, solve the not strong problem of existing PPO/PA66 synthetic plastics intensity and antistatic property.
The present invention is achieved through the following technical solutions:
A kind of PA66 plastics, percentage composition comprises following component by weight: 29% polyphenylene oxide, the carbon fiber of 29% nylon 66,10%, 8% glass fibre, 10% carbon black, 6.5% compatilizer, 6.5% toughner, 1.0% auxiliary agent.
Described auxiliary agent includes oxidation inhibitor, lubricant and thermo-stabilizer; Described oxidation inhibitor: lubricant: the thermo-stabilizer weight ratio is 1: 2: 2.
Compatilizer is selected from the PPO-g-MAH that percentage of grafting is 0.8-1.5%, the polyphenylene oxide grafted maleic anhydride, by adding compatilizer, strengthened the interface compatibility of PPO and PA66, make that between carbon fiber, carbon black, PPO and PA66, the interface mixes more, realize the even mixing of each component in the PPO/PA66 synthetic plastics.
Toughner is selected from the SEBS-g-MAH that percentage of grafting is 0.8-1.5%, and the SEBS grafted maleic anhydride has improved toughness and over-all properties by doping plasticizing agent in synthetic plastics.
The invention has the beneficial effects as follows:
By doping carbon fiber and carbon black, make the intensity of PPO/PA66 synthetic plastics be improved, the synthetic materials antistatic property significantly promotes simultaneously.
Embodiment
Below describe the content of the technical program in detail by specific embodiment.
A kind of PA66 plastics, percentage composition comprises following component by weight: 29% polyphenylene oxide, the carbon fiber of 29% nylon 66,10%, 8% glass fibre, 10% carbon black, 6.5% compatilizer, 6.5% toughner, 1.0% auxiliary agent.
Described auxiliary agent includes oxidation inhibitor, lubricant and thermo-stabilizer; Described oxidation inhibitor: lubricant: the thermo-stabilizer weight ratio is 1: 2: 2.
A kind of preparation method of PA66 synthetic plastics comprises the following steps:
At first, percentage composition comprises following component by weight: 29% polyphenylene oxide, and the carbon black of 29% nylon 66,10%, 6.5% compatilizer, 6.5% toughner, 1.0% auxiliary agent mixes, and makes mixture;
Secondly, the screw extrusion press skill that is 25-40 with length-to-diameter ratio under temperature 230-250 ℃ condition with this mixture goes out processing, obtains the PPO/PA66 synthetic plastics, extrudes in treatment step at this, and adding weight percentage is 10% carbon fiber, 8% glass fibre.
In the present invention, described polyphenylene oxide chemical name is called for short PPO for poly-2,6-dimethyl-Isosorbide-5-Nitrae-phenylate; The chemical name of described nylon 66 is polyhexamethylene adipamide, is called for short PA66.
Compatilizer is selected from the PPO-g-MAH that percentage of grafting is 0.8-1.5%, the polyphenylene oxide grafted maleic anhydride, by adding compatilizer, strengthened the interface compatibility of PPO and PA66, make that between carbon fiber, carbon black, PPO and PA66, the interface mixes more, realize the even mixing of each component in the PPO/PA66 synthetic plastics.
Toughner is selected from the SEBS-g-MAH that percentage of grafting is 0.8-1.5%, and the SEBS grafted maleic anhydride has improved toughness and over-all properties by doping plasticizing agent in synthetic plastics.
The length of carbon fiber is restriction not, is preferably short carbon fiber, and length is 5-10mm, by doping PPO/PA66 synthetic plastics, makes the mechanical property of synthetic plastics significantly improve, and has higher physical strength, and antistatic effect promotes simultaneously.Carbon black selects existing carbon black can satisfy the requirement of technical scheme.That oxidation inhibitor is selected from triglycol is two-and propylene is fine, four [methyl-β-(3 for 3-(the 3-tertiary butyl-4 hydroxy-5-methyl base phenyl), 5-di-t-butyl-4 hydroxy phenyl) propionic ester] one or more combinations in pentaerythritol ester, three (2,4-di-tert-butylphenol) phosphorous acid ester.
Lubricant is selected from one or both combinations in tetramethylolmethane stearate or the two stearic amides of ethyl.
Thermo-stabilizer is selected from one or both combinations in zinc oxide or zinc sulphide.
