Abstract
The invention discloses a polyamide (PA)/acrylonitrile butadiene styrene (ABS) composite material. The PA/ABS composite material comprises the following components in parts by weight: 55-65 parts of PA, 40-50 parts of ABS, 5-8 parts of modified polystyrene (PS), 1-2 parts of initiators and 0.1-0.3 part of an antioxidant. The PA/ABS composite material is provided and used for solving the problem of poor compatibility of a blend of PA and ABS in the prior art.
Description
Technical field
The present invention relates to a kind of polyblend, particularly a kind of PA/ABS matrix material.
Background technology
Polyamide (PA) is commonly called as nylon, is a kind of thermoplastic engineering plastic that is widely used in fields such as automobile, electronics, machinery.PA has good wear resistance, shock resistance and self lubricity, to the tolerance of number of chemical medicine, but not anti-highly basic, and water-intake rate is big, heat-drawn wire is low, creep properties is big.These shortcomings have limited its application to a great extent.(ABS) carries out blending and modifying to nylon with acrylonitrile-butadiene-styrene (ABS), improved the shortcoming of nylon, widened the Application Areas of nylon.By the PA/ABS matrix material that blend makes, both had wear resistance, shock resistance and the self lubricity of nylon, have toughness and the rigidity of ABS again.But nylon is the polymkeric substance of a kind of crystallinity, strong polarity, and ABS is the polymkeric substance of a kind of amorphism, low-pole, and both solubility parameters differ bigger, so the blend of PA and ABS exists the relatively poor shortcoming of consistency.
Summary of the invention
The object of the present invention is to provide a kind of PA/ABS matrix material, with the relatively poor problem of blend compatibility of PA and ABS in the solution prior art.Technical scheme is as follows:
A kind of PA/ABS matrix material comprises following component with the weight part number scale:
PA 55-65 part
ABS 40-50 part
Modification PS 5-8 part
Initiator 1-2 part
Oxidation inhibitor 0.1-0.3 part
Described modification PS handles through tensio-active agent.
Described tensio-active agent is silane coupling agent or titanate coupling agent.
Described initiator is dimethylaminoethyl acrylate methyl ammonia ethyl ester or accelerine.
Described oxidation inhibitor is four (β-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic acid) pentaerythritol ester, β-(4-hydroxy phenyl-3, the 5-di-t-butyl) the positive octadecanol ester of propionic acid, 2,6 ditertiary butyl p cresol or 4,4 '-thiobis (the 6-tertiary butyl-3-(methyl) phenol).
The present invention adopts through surfactant-modified polystyrene (PS) later and PA and ABS blend, PS is the low-pole superpolymer, the molecular chain softness, consistency through the PS of modification and PA and ABS is good, can effectively reduce the interfacial tension of PA and ABS two-phase, impel two-phase evenly to disperse, under action of evocating, crosslinking reaction take place, form the equal phase structure of stable state, make PA and ABS get consistency and improve.And PS has difficult characteristic of being corroded by strong acid and strong base, and its adding can improve the corrosion resistance nature of PA/ABS matrix material.
Embodiment
In order better to understand and to implement, describe the present invention in detail below in conjunction with embodiment.
Embodiment 1
With PA55 part, ABS40 part, modification PS5 part, 1 part of initiator dimethylaminoethyl acrylate methyl ammonia ethyl ester, oxidation inhibitor four (β-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic acid) pentaerythritol ester is being pre-mixed in high-speed mixer for 0.1 part, extrudes cooling granulation then by the parallel double-screw mixing extruder.
Embodiment 2
With PA58 part, ABS43 part, modification PS6 part, 2 parts of initiator dimethylaminoethyl acrylate methyl ammonia ethyl esters, oxidation inhibitor β-(4-hydroxy phenyl-3, the 5-di-t-butyl) the positive octadecanol ester of propionic acid is being pre-mixed in high-speed mixer for 0.2 part, extrudes cooling granulation then by the parallel double-screw mixing extruder.
Embodiment 3

Embodiment 4
With 65 parts of PA, 50 parts of ABS, 8 parts of modification PS, 2 parts of initiator accelerines, oxidation inhibitor 4,4 '-thiobis (the 6-tertiary butyl-3-(methyl) phenol) 0.2 part in high-speed mixer, be pre-mixed, extrude cooling granulation then by the parallel double-screw mixing extruder.
The comparative example
With PA65 part, ABS50 part, 2 parts of initiator dimethylaminoethyl acrylate methyl ammonia ethyl esters, oxidation inhibitor four (β-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic acid) pentaerythritol ester is being pre-mixed in high-speed mixer for 0.3 part, extrudes cooling granulation then by the parallel double-screw mixing extruder.
Test previous embodiment 1-4 and comparative example's products obtained therefrom obtain result as shown in table 1.Wherein the Izod shock strength is pressed the ISO-180 standard testing; Tensile strength is pressed the ISO-527 standard testing, and draw speed is 50mm/min; Water-intake rate is pressed the ISO62-2008 standard testing.
Table 1
As shown in Table 1, the mechanical property that adding modification PS does not add the PA/ABS matrix material of modification PS relatively increases, and this shows that modification PS can impel PA and ABS two-phase evenly to disperse, thereby obtains mechanical property preferably.
The above only is preferred embodiment of the present invention, does not limit the present invention, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
