The invention relates to a polyphenylene oxide/polyamide 66 (PPO/PA66) synthetic plastic. The synthetic plastic comprises the following components by weight percent: 25-35% of PPO, 25-35% of PA66, 15-20% of carbon fiber, 8-12% of carbon black, 5-10% of a compatilizer, 5-10% of a toughening agent and 0.5-1.5% of additives.
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 PPO/PA66 synthetic plastics, percentage composition comprises the polyphenylene oxide of following component: 25-35% by weight, the nylon 66 of 25-35%, the carbon fiber of 15-20%, the carbon black of 8-12%, the compatilizer of 5-10%, the toughner of 5-10%, the auxiliary agent of 0.5-1.5%.
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, so that the interface mixes more between carbon fiber, carbon black, PPO and the PA66, 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, so that the intensity of PPO/PA66 synthetic plastics is improved, the synthetic materials antistatic property significantly promotes simultaneously.
Embodiment
Below describe the content of the technical program in detail by specific embodiment.
