Abstract
The invention provides a novel PC/ABS alloy composite reinforced by cyclic carbon fiber filaments. The composite is composed of the cyclic carbon fiber filaments (1) on the outer layer and internal PC/ABS alloy (2) and comprises, by weight, 60-80 parts of PC, 20-40 parts of ABS, 5 parts of compatilizer and 5-20 parts of cyclic carbon fiber filaments. The composite is prepared through the steps that 1, the surface-treated cyclic carbon fiber filaments are dried for use, and meanwhile the PC and the ABS are dried for use; 2, the PC, the ABS and the compatilizer are evenly mixed for use; 3, the PC, ABS and compatilizer mixture is added into a double-screw extruder, the cyclic carbon fiber filaments are added from a side feeding port of the double-screw extruder, extrusion granulation is performed, and a PC/ABS alloy composite melt reinforced by the cyclic carbon fiber filaments is obtained; 4, the extruded PC/ABS alloy composite melt reinforced by the cyclic carbon fiber filaments is cooled, blow-dried and then cut into granules, and the granules are dried. Under the effect of the cyclic carbon fiber filaments, the tensile strength of the PC/ABS alloy is improved, and the elongation and heat distortion temperature of the PC/ABS alloy are increased.
Description
Technical field
The present invention relates to a kind of novel carbon fiber circulation silk and strengthen PC/ABS alloy composite materials, belong to technical field of alloy material.
Background technology
PC/ABS, polycarbonate and acrylonitrile-butadiene-styrene copolymer and mixture, it is the thermoplastic plastic rubber by polycarbonate (Polycarbonate) and polyacrylonitrile (ABS) alloy, combine the excellent specific property of bi-material, the formability of ABS material and the character such as the mechanicalness of PC, shock strength and heatproof, uvioresistant (UV), can be widely used on automotive interior parts, Business Machine, the communication apparatus, electrical home appliances and set lights.
PC and ABS has certain consistency, but the consistency of PC and ABS affects very large by the model of two components, the factor such as proportioning and complete processing.In order to effectively improve interface compatibility, most effectual way adds compatilizer in co-mixing system.Common expanding material has: the multipolymer, amido, SAN, two-pack increase-volume etc. of the grafts of maleic anhydride MAH grafting POE, ABS, PE grafts, SMA graft copolymer (SMA), acrylic or methacrylic acid esters.
PC/ABS alloy can comprehensive both premium properties.Improve thermotolerance and the tensile strength of ABS on the one hand, reduce PC melt viscosity on the other hand, improve processing characteristics, minimizing goods internal stress and shock strength are to the susceptibility of products thickness
The weak point of PC/ABS alloy is: tensile strength, elongation and heat-drawn wire decline to some extent.
Carbon fiber is the tencel material of the high strength of a kind of carbon content more than 95%, high modulus fibre.It to be piled up along fiber axial direction due by organic fibres such as flake graphite crystallites to form, the micro crystal graphite material obtained through carbonization and graphitization processing.Carbon fiber " soft outside but hard inside ", quality is lighter than metallic aluminium, but intensity is higher than iron and steel, and has characteristic that is corrosion-resistant, high-modulus, defence and military and civilian in be all important materials.It not only has the intrinsic intrinsic property of carbon material, has both again the soft workability of textile fibres, is fortifying fibre of new generation.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, provide a kind of novel carbon fiber circulation silk to strengthen PC/ABS alloy composite materials.
Novel carbon fiber circulation silk of the present invention strengthens PC/ABS alloy composite materials, be made up of outer field carbon fiber circulation silk (1) and inner PC/ABS alloy (2), each component concentration is as follows: PC is 60-80 weight part, ABC is 20-40 weight part, compatilizer is 5 weight parts, carbon fiber circulation silk 5-20 weight part
Novel carbon fiber circulation silk of the present invention strengthens the preparation method of PC/ABS alloy composite materials, comprises the steps:
1) by surface treated carbon fiber circulation silk dry for standby; Simultaneously by PC and ABS dry for standby;
2) PC, ABS and compatilizer are mixed for subsequent use;
3) PC, ABS and compatilizer mixture are added twin screw extruder; And the silk that circulated by carbon fiber adds at the side spout of twin screw extruder, extruding pelletization, obtain carbon fiber circulation silk and strengthen PC/ABS alloy composite materials melt;
4), after being dried up by the carbon fiber circulation silk extruded enhancing PC/ABS alloy composite materials melt cooling, pelletizing is dried, and obtains carbon fiber circulation silk and strengthens PC/ABS alloy composite materials.
Novel carbon fiber circulation silk of the present invention strengthens PC/ABS alloy composite materials, due to the effect of carbon fiber circulation silk, improves PC/ABS alloy tensile intensity, elongation and heat-drawn wire.
