Abstract
The invention discloses a composite material of green environment protective flameproof ABS alloy and making method, which is composed of ABS and PVC, wherein fitful quantity of heat stabilizer and lubricant are added into co-blending system, which improves flameproof property with fire retardant within Sb2O3 and halogen fire retardant; the composite material reinforces extending property, bending property and hinging property, which improves mechanic strength and electric property obviously.
Description
Technical field:
Patent of the present invention belongs to the polymer composite field, relate to a kind of green environmental protective flame-proof ABS alloy matrix material and preparation method thereof, the present invention has increased the range of application of ABS resin, have good economic benefit and social benefit, be specially green environmental protective flame-proof ABS alloy matrix material and preparation method thereof.
Background technology:
ABS resin typically refers to the graft copolymer of polybutadiene rubber and monomer styrene and propylene hydrocarbon, have shock resistance, high rigidity, oil-proofness, lower temperature resistance, chemical proofing, characteristics such as physical strength and excellent electrical properties, but the flame retardant properties of ABS is also bad, the method that obtains green environment-protective flame-retardant ABS is to add an amount of stagnant combustion type polymer P VC in ABS, not only can reduce the consumption of inorganic combustion inhibitor, can also improve compound matter PVC, improve the mechanical property of compound system.Its injection, extrusion moulding product have been widely used in fields such as building, automobile, electronics, electrical equipment and medicine equipment.
Summary of the invention:
For shortcoming such as the flame retardant properties that overcomes ABS is bad, patent of the present invention is with brand-new fire-retardant, enhancing, toughness reinforcing, anti-aging technology, integrated use is in the ABS resin modification, the particularly application of novel flame-retardant system, material modified physical and mechanical properties and thermal-oxidative aging property all are greatly improved, make this novel material all be better than existing common ABS resin, and significantly reduce product cost at every aspect of performance.
The objective of the invention is that deficiency at the ABS resin aspect of performance provides that a kind of flame retardant resistance, intensity are big, good toughness, good weatherability, the ABS/PVC matrix material that ageing-resistant performance is good.
Embodiment:
The preparation method of green environmental protective flame-proof ABS alloy of the present invention is: the ABS/PVC system has " island " structure, and PVC constitutes external phase with SAN, and the rubber particles among the ABS is as disperse phase in the blend process, and its particle diameter does not have to change substantially.When material was subjected to external impacts, rubber particles became focal point of stress, made material bring out crazing, but simultaneously rubber particles again disproportionation, stop crazing or bring out new crazing, thereby improved the erosion-resisting characteristics of material.
The flowability of ABS/PVC co-mixing system is poor than ABS, and the thermostability of PVC is bad, and in the course of processing, the shearing force of being heated is easily degraded, so should add an amount of thermo-stabilizer and lubricant in co-mixing system.Heat stabilizing system commonly used is metallic soap class and lead salt stabilising system, and lubricating system adopts paraffin.Experimental results show that employing metallic soap and color articles are preferable, the lubrication that paraffin and metallic soap heat stabilizing system are used is that the stablizer mating reaction is good more than lead salt.Suitably adopt lower molecular weight polyvinyl chloride resin that co-mixing system stability is obviously improved simultaneously.Because reduce with the PVC molecular weight, Intermolecular Forces weakens, and melt viscosity descends, thereby reduces intermolecular heat of friction, reduces the heat of friction effect, and the system thermostability is improved.
Claims (6)
1, the green environmental protective flame-proof ABS alloy matrix material is a kind of new modified engineering plastics, by ABS and PVC alloy composition, adds an amount of thermo-stabilizer, lubricant and fire retardant in co-mixing system.
