Description

The glass fiber-reinforced polycarbonate matrix material
Technical field
The present invention relates to the matrix material preparing technical field, especially a kind of glass fiber-reinforced polycarbonate matrix material.
Background technology
Matrix material has very important effect for the development of modern science and technology, and its characteristics are high strength, low density, easy-formation and easy to process etc.Polycarbonate is preferably non-crystalline type engineering plastics of a kind of transparent and impact resistance, after adopting glass fibre that polycarbonate is strengthened, the tensile strength of matrix material, flexural strength and modulus in flexure have had raising to a certain degree, but its impact resistance but has certain decline.Be applied to the polycarbonate composite material of high-modulus high impact resistance environment for some, need to add the toughner that MBS etc. improves its shock resistance in the process of its preparation, but the cost of general toughner is higher, therefore, the low-cost toughening technology of researching and developing a kind of glass fiber-reinforced polycarbonate matrix material is necessary.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of glass fiber-reinforced polycarbonate matrix material that contains low-cost toughner is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of glass fiber-reinforced polycarbonate matrix material, by mass percentage, its component comprises: 48-90% polycarbonate, 1-40% glass fibre, 0.5-10% maleic anhydride grafted polyethylene, 0.01-2% antioxidant.
Described polycarbonate is copolymerization or polycarbonate homopolymer, and the melting index scope is 1-60g/10min.
Described glass fibre is alkali free glass fibre or medium-alkali glass fibre, and diameter range is 1-20 μ m, and the surface is untreated, also can partly or entirely pass through one or more coupling agent treatment.
Described maleic anhydride grafted polyethylene is to be formed through maleic anhydride graft by polyethylene, maleic anhydride content is 0.0001-10%, polyethylene is one or both the mixture in high density polyethylene(HDPE), Low Density Polyethylene or the super-high density polyethylene, or is side chain or straight linear polyethylene or both mixtures.
Described antioxidant is vapour bar irgasfos 168.
A kind of glass fiber-reinforced polycarbonate composite manufacture method, concrete steps are:
1) prepares by mass percentage following material: 48-90% polycarbonate, 1-40% glass fibre, 0.5-10% maleic anhydride grafted polyethylene, 0.01-2% antioxidant;
2) according to preseting ratio, from charging opening material is added dual-screw-stem machine, melt temperature is set to 290 ℃, and screw speed is 500rmp/min, finishes granulation through behind mixing, the underwater cutpellet;
3) injection temperature is set to 300 ℃, the injection moulding test bars.
Beneficial effect: glass fiber-reinforced polycarbonate matrix material of the present invention is take maleic anhydride grafted polyethylene as toughner; gained matrix material shock resistance is better, is conducive to reduce production costs, and enhances productivity; the simple environmental protection of preparation method of the present invention is fit to large-scale production.
