Description
Technical Field
The invention relates to the technical field of high polymer materials, in particular to a high-rigidity low-warpage permanent antistatic reinforced PPO/LCP compound and a preparation method thereof.
Background
Polyphenylene Oxide (PPO) is a thermoplastic resin obtained by oxidative coupling polymerization of 2, 6-disubstituted phenol, and is generally in the form of an earthy yellow powder. Polyphenylene ethers synthesized from 2, 6-dimethylphenol are commonly used, and have an excellent combination of properties, such as non-toxicity, low relative density, excellent mechanical strength, stress relaxation resistance, creep resistance, heat resistance, water resistance, dimensional stability, and flame retardancy and self-extinguishing properties; but has the biggest characteristics of excellent dimensional stability and outstanding electric insulation under long-term load; and the use temperature range is wide, and the product can be used for a long time within the range of-127-121 ℃. PPO is therefore particularly suitable for use in an epicyclic tray in the manufacture of IC chips, but PPO has good electrical insulation and must be antistatic modified.
The Liquid Crystal Polymer (LCP) has a structure of wholly aromatic polyester and copolyester, and also has a structure of densely arranged linear polymer chains, and the formed product has the characteristic of good unidirectional mechanical properties. LCP has good high temperature performance (heat distortion temperature of 121-355 ℃), flame retardancy, corrosion resistance, high dimensional stability, low hygroscopicity, extremely low linear expansion coefficient, high impact strength and rigidity (the strength of LCP is more than that of steel, but the rigidity is only 15% of that of steel according to the same weight comparison).
The Chinese patent of invention CN201810959831.X discloses an alloy antistatic material for a tray for a wafer, and because the alloy antistatic material adopts conductive carbon black as an antistatic agent, the conductive carbon black can generate a powder-shedding phenomenon in the repeated use process for many times, which can seriously pollute the wafer in the tray; meanwhile, the mechanical property of the prepared material is seriously influenced because the inorganic powder of the conductive carbon black is added into the system.
The invention of Chinese patent application CN201110376995.8 discloses a permanent antistatic PBT/PPO alloy and a preparation method thereof, because PBT is a highly crystalline polymer, the addition of PBT into a system can cause severe warp deformation of materials during injection molding of flat plate products, and particularly, the warp deformation is more severe when reinforced glass fibers are added, which can seriously affect the application range of the materials.
Therefore, there is a need to develop a PPO/LCP composite and a method for preparing the same to enhance the high rigidity, low warpage and permanent antistatic properties of the material.
