This composite of continuous fiber thermoplastics rosin provided by the invention improves its resinousness greatly after being added the micro glass bead, nucleater and modifier. Therefore, this continuous fiber thermoplastics material of the invention is characterized with high rigidity, tensile-and- bending strength and the high shock resistance and heat distortion temperature at low and high temperature, which increases the material's tensile strength from 220MPa to 300MPa and bending modulus from 15GPa to 22GPa, which is increased by nearly 50%.

Description

Continuous fiber reinforced thermoplastic composite material
Technical field
The present invention relates to a kind of continuous glass fibre enhanced thermoplastic composite.
Background technology
In continuous fiber reinforced thermoplastic resin composite material, the existing way of fiber is not only successive, but also arranges in the mode of almost parallel.Fiber can be given full play to the high-strength and high-modulus characteristic of fiber on its length direction.The level that can reach steel alloy that has is so it is substituting steel in the use aspect a lot.
Existing continuous fiber reinforced thermoplastic composite material has better comprehensive mechanical property, because it does not consider the improvement to resin property, so its rigidity, flexural strength and tensile strength often do not reach requirement.The technology that disclose as Chinese patent 01145415 and 88102218 are owing to the adhesive property of only considering fiber surface and resin and fiber have been ignored improvement to resin by the impregnability of resin.
Summary of the invention
The technology that the present invention need solve is to disclose a kind of continuous fiber reinforced thermoplastic composite material, to overcome the not high defective of rigidity of material, flexural strength and tensile strength that prior art exists.
Technical conceive of the present invention is such:
Rigidity, flexural strength and the tensile strength of the present invention in order to promote continuous fiber reinforced thermoplastic composite material added glass microballon and nucleator in matrix material, thereby obtained comparatively ideal results.
The fiber-reinforced thermoplastic resin matrix material, its performance is by the performance decision of strongthener and resin two aspects.The arrangement mode of continuous fibre and almost parallel thereof is not fully exerted its performance in matrix material, but because resin itself also is the important component part of material, its performance has restricted the overall performance of material to a great extent.
Technical scheme of the present invention:
The said continuous fiber reinforced composite materials of the present invention comprises following component and content (parts by weight):
Continuous fibre 25~80
Thermoplastic resin 20~75
Glass microballon 0~10
Nucleator 0.05~1.5
Said thermoplastic resin comprises current commercial all thermoplastic resin kinds, comprise a kind of and composition thereof in nylon, polycarbonate, polypropylene, polyethylene, polystyrene type, polyphenylene oxide, polyphenylene sulfide, polyoxymethylene, the polymethylmethacrylate etc., or resin alloy, to satisfy various needs, the optimization polypropylene grafts, as maleic anhydride inoculated polypropylene, or the blend of polypropylene and polycarbonate
Said continuous fibre comprises wherein one or more such as glass fibre, carbon fiber, steel fiber, and they exist in sheet material in a continuous manner.
Said glass microballon is a kind of uniqueness and the nonpoisonous and tasteless nonmetal hollow minute particle of stable performance, sky contains rare gas elementes such as nitrogen and carbonic acid gas, mainly be made up of silicon-dioxide and aluminium sesquioxide etc., particle size range is 10~250um, and tap density is 0.35~0.45g/cm 3Hollow glass micropearl has characteristics such as easily disperse, good fluidity, proportion are little, wear-resisting, high temperature resistant, acid and alkali-resistance because of its special structure.So, add the density that hollow glass micropearl has reduced material, improved the stretching and the flexural strength of matrix material, improved the heat-drawn wire of material.
Said nucleator can be an inorganic additives, such as talcum powder, silicon-dioxide, kaolin; The organic compound nucleator is such as monobasic or polycarboxylate, organophosphate, diphenylmethylene sorbyl alcohol, rosin based nucleator; The NA series nucleator of polymer novel material company limited is moulded by preferred Shanghai section, is the nucleator of NA-45, NA-9930T such as the trade mark.Thermoplastic resin is exactly the poor rigidity of material with respect to the weakness of a maximum of thermosetting resin.This is because most of thermoplastic resins all are unformed shape or half hitch crystalline state, lacks crosslinked cause between the macromole.In the present invention,, impel its quick nucleation, crystallization, improve percent crystallization in massecuite and crystal grain thinning and make its arrangement regular, reach and improve intensity and inflexible purpose by adding NA series nucleator.
Continuous fiber reinforced thermoplastic resin composite material provided by the invention adds after the properties-correcting agent owing to added glass microballon and nucleator in resin, and resin property is significantly improved.So continuous fibre enhanced thermoplastic composite of the present invention has shock resistance high under very high rigidity, stretching and flexural strength and low, the high temperature and high heat-drawn wire, make the tensile strength of material bring up to 400Mpa from 220Mpa, modulus in flexure rises to 30Gpa by 15Gpa, has improved nearly 100%.
Continuous fiber reinforced thermoplastic composite material provided by the invention can conventional employing powder electrostatic absorption method also can adopt conventional melt impregnation and reaction method preparation.Continuous fibre fully plastifies by baking oven and high temperature die head through after fully flooding, and is pressed into flaky composite material through multi-rolling mill again, and its thickness is preferably between 0.3~2.0mm.Sheet material is cut into certain-length and width, and on demand angle and mode stack, and place mould compression moulding, obtain the goods that need.
Embodiment
Below in conjunction with embodiment, the performance of continuous fiber reinforced thermoplastic resin flaky composite material is described in further detail.
In the following example, antioxidant 1010 is: four (β-(3,5-di-tert-butyl-4-hydroxy phenyl) propionic acid) pentaerythritol ester; Oxidation inhibitor DSTP is: thio-2 acid (octadecyl ester); Nucleator NA-45, NA-9930T mould the NA series nucleator trade mark of polymer novel material company limited for Shanghai section.
