Abstract
The invention relates to a alloy material of nylon and ABS, which comprises: 30-75% nylon 6 section, 15-30% ABS, 5-30% SAN, 1-10% solvent, 0.1-1% anti-oxidant, and 0.1-0.5% lubricant. The preparation method comprises: weighting materials to mix in strong mixer for 2-5min; out feeding to extrude and granulate in screw machine with rotation speed of 180-600r/min at 160-260Deg. This invention has both the advantages of nylon 6 and ABS.
Description
Technical field
The present invention relates to a kind of nylon and ABS alloy material and preparation method thereof, can be used for injection moulding automobile wheel cover, panel board circle frame and other electronic products belong to nylon/ABS technical field of alloy material.
Technical background
Nylon/ABS alloy is released by the Borg Warner Chemicals company and the Monsanto company of the U.S. the earliest, has heat-drawn wire than PA height, and the higher characteristics of vicat softening temperature, thereby become the ideal material of making trolley parts such as body of a motor car coverboard.
Advantages such as PA6 has wear-resisting, anti-solvent, oil resistant, use temperature are wide, but have also that water-absorbent is big, deficiency such as poor dimensional stability, low temperature and dry state shock strength are low, limited its use greatly.With PA6 and ABS blend, can make the toughness of existing ABS, again the alloy of thermotolerance and the oil-proofness of PA be arranged.This kind alloy is widely used in automobile, electronic apparatus, home-use device etc.But because the polymkeric substance that PA6 is a kind of crystallinity, strong polarity, melt viscosity is very low, and ABS is the polymkeric substance of a kind of amorphism, low-pole, the solubility parameter of the two differs bigger, it is incompatible to belong to thermodynamics, simple worker mixes and causes two-phase interface tension force very big, thereby cause mechanical property relatively poor, thereby will obtain nylon with practical value/ABS alloy material, must carry out morphology Control and interface modification.
Summary of the invention
The object of the present invention is to provide a kind of dimensional stabilizing that has, the intensity height, outward appearance is good, high workability, the nylon of chemical-resistant and ABS alloy material and preparation method thereof.
For realizing above purpose, technical scheme of the present invention provides a kind of nylon and ABS alloy material, it is characterized in that, it is made by following materials of weight proportions:
Nylon 6 slice 30-75%
ABS 15-30％
SAN 5-30％
Compatilizer 1-10%
Oxidation inhibitor 0.1-1%
Lubricant 0.1-0.5%
The relative viscosity of described nylon 6 slice is 2.4-3.8;
Described ABS is vinyl cyanide, divinyl, styrene copolymer;
Described SAN is the multipolymer of vinylbenzene and vinyl cyanide, and its melting index is 15-40g/10min;
Described compatilizer is vinylbenzene, vinyl cyanide and copolymer-maleic anhydride (SAM), and maleic anhydride grafting ratio is 6-20%;
Described oxidation inhibitor is the compound of a kind of Hinered phenols antioxidant and a kind of Hinered phenols antioxidant and phosphite ester kind antioxidant.
Described lubricant is the ultra-high molecular weight polysiloxane.
The preparation method of a kind of nylon and ABS alloy material is characterized in that, its method is as follows:
(1) weighs raw material by weight ratio;
(2) all raw materials are put into high-speed mixer and mixing 2-5 minute;
(3) discharging;
(4) raw materials mixed is placed screw rod machine extruding pelletization, the rotating speed of screw rod machine is 180-600 rev/min, and temperature is 160-260 ℃.
Nylon 6 has advantages such as wear-resisting, anti-solvent, oil resistant, use temperature be wide, is the engineering plastics of current production rate maximum.
Vinyl cyanide, divinyl and styrene copolymer have been gathered rigidity that glossiness that vinylbenzene has and formability, vinyl cyanide have and resistance to chemical reagents and excellent mechanical property, shock-resistance that divinyl has, can improve dimensional stability, shock strength, chemical resistant properties and the processing characteristics of nylon with nylon blending.
SAN has excellent flowing performance and anti-medicine performance and rigidity, and is compatible with the nylon part, can improve the rigidity and the flowing property of alloy material.
Because nylon and ABS belong to the thermodynamics incompatible material, the adding of vinylbenzene, vinyl cyanide and copolymer-maleic anhydride can improve both consistencies, improve the shock strength and the elongation at break of material, but because the fragility of vinylbenzene, vinyl cyanide and copolymer-maleic anhydride self, add excessive vinylbenzene, vinyl cyanide and copolymer-maleic anhydride and can reduce the impact property of material on the contrary, relatively Shi Yi addition is 1-10%, and better addition is 3-8%.
Oxidation inhibitor is a kind of Hinered phenols antioxidant, can be 1076 and the compound of a kind of Hinered phenols antioxidant and phosphite ester kind antioxidant, can be 1010 and 168 (1: 1), 1010 are mainly used in the oxidation that prevents ABS/SAN, and 168 mainly prevent the oxidation of PA6.
The ultra-high molecular weight polysiloxane improves the materials processing flowability as lubricant, reduces frictional coefficient, improves smooth property, improves surface luster.
The present invention adopts nylon 6 and ABS resin, has prepared a kind of dimensional stabilizing that has, the intensity height, outward appearance is good, high workability, the nylon of resistance to chemical reagents/ABS alloy material, size instability, the easily shortcoming of warpage, and the inconsistent characteristics of thermodynamics of nylon 6 and ABS material of nylon material have been solved.
Advantage of the present invention is the characteristic that has had nylon 6 and ABS concurrently, and scantling is stable, the intensity height, and outward appearance is good, high workability, resistance to chemical reagents.
