Abstract
The present invention relates to a composite glass fiber reinforced polyester (PET) material and a preparation method thereof. The composite glass fiber reinforced polyester (PET) material uses PET as a substrate, and glass fibers processed by a nylon nucleating agent, an epoxy resin toughening and chain extender, an antioxidant and epoxy resin with water solubility, or glass fibers processed by the water miscible liquid of epoxy resin are added; thereby, the composite glass fiber reinforced polyester (PET) material is melted and extruded in a composite mode at 250 to 280 DEGC by granulating the PET and the glass fibers. The composite material has the characteristics of easy processing, high impact strength and high tensile strength.
Description
The present invention relates to matrix material with glass-fiber-reinforced polyester (PET).
Polyester (PET) has good wear resistance, thermotolerance, chemical proofing, be particularly useful for making fiber and film, but, PET is as the engineering plastics time spent, the shortcoming that exists is that its crystallization velocity is slow, shock resistance and poor processability, this has hindered its widespread use as engineering plastics, " synthetic resins and plastics handbook chemical industry press version in 1991 has been reported the mechanical property and the processing characteristics of going REINFORCED PET with glass fibre, as the complicated and low shortcoming of mechanical property of processing characteristics of product grade Rynite530 (content of glass fiber is 30%).
In order to overcome the complicated and low shortcoming of mechanical property of above-mentioned processing characteristics, the present invention adopts cheap commercially available organism as components such as nucleator, toughner, chainextenders, and it is simple to obtain a kind of preparation technology, and cost is low, the matrix material of the glass fibre REINFORCED PET of excellent performance.
This matrix material be with PET as matrix, be equipped with the nylon-type polymkeric substance as nucleator, Resins, epoxy is as toughness reinforcing, chainextender, surface treated glass fibre is as toughener, each component (weight %) proportioning is as follows:
PET 60-66
Nylon-type nucleator 1-3.5
Resins, epoxy chainextender 0.1-1.0
Antioxidant 1010 or 1222 0.05-0.2

(diameter is 6-17 μ m)
Above-mentioned nylon is nylon 6, nylon 66, and one or more in the nylon 1010, above-mentioned Resins, epoxy are the 2-4 functional group epoxy resin, above-mentioned PET intrinsic viscosity is a 0.60-0.65 Grams Per Minute liter.Above-mentioned glass fibre is the glass fibre of water-soluble epoxy resin processing and the glass fibre that the Resins, epoxy water miscible liquid is handled.
With pre-dry PET 60-66, nylon 1-3.5, oxidation inhibitor 0.05-0.2, Resins, epoxy 0.1-1.0 (weight %), after in super mixer, do mixing, again in twin screw extruder with glass fibre 25-35 (weight %) at 250-280 ℃, extrude through fusion is compound, granulation forms.
Polyester of the present invention (PET) is strong with the glass fibre interfacial adhesion, because Resins, epoxy is effective to the PET chain extension, nucleator nylon is fast to the PET crystallization rate simultaneously, make the composite materials property excellence that makes, and cost is low, easily processing.
