The PA/PP alloy material is PA/PP-GF material with PP content more than 20%, and the melt stability and the melt strength are improved by matching the components, so that the appearance of the product has no tiger skin lines and obvious layering effect. In addition, the impact strength of the product obtained by adopting the PA/PP alloy material is obviously improved. The PA/PP alloy material provided by the invention can be used for preparing automobile structural parts, such as fans, wind protection rings, water chambers and the like.
Description
Technical Field
The invention relates to the technical field of high polymer materials, in particular to a PA/PP alloy material and a preparation method and application thereof.
Background
The PA/PP alloy material has the advantages of simultaneously keeping the advantages of the strength, toughness and heat resistance of the PA resin, and the PP resin has the advantages of low density, no water absorption and the like, becomes a material with better comprehensive performance, and can be widely applied to automobile parts such as engine decorative covers, door handles and the like. The content of PP in the PA/PP alloy in the industry is generally less than 15 percent so as to ensure the island phase structure, so that the composite material has excellent strength, toughness and appearance. The higher the PP content is, the more obvious the weight reduction of the material is, but when the PP content is too high, the impact strength of the material is generally lower due to poor compatibility of PA and PP, and the PA/PP alloy material is layered due to lower melt strength and lower melt stability of a PA/PP system, so that tiger stripes appear on the appearance of the product. The tiger skin patterns are defects of alternate bright and dark specks on the surface of a manufactured part caused by unstable melt flow due to stretching and shearing deformation of the material in the melt flow process, and are similar to tiger patterns. The patent CN106147008A adds the polystyrene polyolefin crosslinking elastomer into the PP-TD series material, so that the occurrence of tiger stripes of the PP-TD composite material is avoided; CN105219005a adds thermoplastic polyolefin or a mixture of thermoplastic polyolefin and epoxy fatty acid methyl ester to PP-TD composite material to improve tiger skin line. All the patents improve tiger stripes in a PP-TD system, and the tiger stripes are easy to appear in a PA/PP-GF system, and the improvement of the tiger stripes is rarely reported.

The melt flow rate MFR of the copolymer polypropylene may be from 5 to 110g/10min. The melt flow rate MFR of the polypropylene copolymer was measured according to ISO 1133-2011 at 230℃under 2.16Kg.
Preferably, the elastomer is a polyamide elastomer with PA6 as the hard segment. The polyamide elastomer taking the PA6 as a hard segment has higher compatibility with polyamide resin, especially the PA6 resin, has more stable melt flow, is not easy to generate phase analysis phenomenon under high-speed shearing, and is not easy to generate tiger skin line phenomenon.
Preferably, the auxiliary agent is 0.3-1 part of antioxidant and/or 0.3-1 part of lubricant.
Preferably, the antioxidant is one or more of amines, phosphites, semi-hindered phenols and cyclic aromatics.
The lubricant is one or more of montan esters, metal soaps, stearic acid composite esters and amides.
The invention also provides a preparation method of the PA/PP alloy material, which comprises the following steps: premixing polyamide resin, polypropylene resin, polyacrylamide, elastomer, ethylene-vinyl acetate-maleic anhydride and an auxiliary agent, adding glass fiber, blending and extruding, bracing, cooling and granulating to obtain the PA/PP alloy material.
Preferably, the cooling is water cooling and then air cooling.
Preferably, the blending extrusion adopts a double screw extruder, and the extrusion temperature is 150-280 ℃.
Preferably, the extrusion temperature of the PA6 alloy is 150-170 ℃,180-200 ℃,200-215 ℃,210-225 ℃,220-230 ℃,220-240 ℃,220-240 ℃,225-245 ℃,225-245 ℃ and 225-245 ℃ respectively; the extrusion temperature of the PA66 alloy is respectively 200-220 ℃,230-250 ℃,240-255 ℃,250-260 ℃,260-280 ℃,260-280 ℃,260-280 ℃,265-280 ℃,260-280 ℃ and 260-280 ℃. The invention also provides application of the PA/PP alloy material in preparing an automobile structural member. The automobile structural member can be a fan, a wind protection ring, a water chamber and the like.
Compared with the prior art, the invention has the beneficial effects that:
the PA/PP alloy material is PA/PP-GF material with high PP content, and has no tiger skin lines and obvious layering. According to the invention, the problem of insufficient impact strength of the PA/PP alloy material is solved by adding the elastomer, and the melt stability is improved: the elastomer has high compatibility with PA, and phase separation phenomenon can not occur under the shearing action; the elastomer and the PP are incompatible due to different polarities, so that the PP phase part of the injection molding part is more difficult to form tiger stripes; by adding ethylene-vinyl acetate-maleic anhydride, the crosslinking point can be formed by reacting with amino groups at the end of the polyamide resin, so that the effect of increasing the melt strength of the material is achieved; the polyacrylamide and ethylene-vinyl acetate-maleic anhydride terpolymer are compounded to play a role in compatibilizing PA and PP resins, so that layering is avoided; the elastomer, the ethylene-vinyl acetate-maleic anhydride and the polyacrylamide are blended to form a network-shaped molecular structure formed by covalent bonds, hydrogen bonds and molecular entanglement, so that the tiger stripes on the appearance of the product are avoided.
