Description
Technical field
The invention belongs to halogen-free flame retardant PC/ABS alloy material, be specifically related to a kind of polynite synergistic fire retardation PC/ABS alloy material and preparation method thereof.
Background technology
The alloy material of PC/ABS is a kind of modified engineered plastic by mixing rear synthesis.The alloy of PC/ABS can overcome the shortcoming of two kinds of raw materials self, develop the advantage of the other side, after both are blended, one can improve the thermotolerance of PC/ABS, impact and tensile strength, it two can reduce polycarbonate melt viscosity, improves processing characteristics, reduces PC notch sensitivity, improve PC stress cracking situation, reduce production cost.
In recent years, in order to meet at electronics, the particular requirement of the Application Areas fire safeties such as electric product, PC/ABS alloy must with the flame retardant properties of excellence, and the flame-retarded technology of PC/ABS alloy becomes the focus of people's research.Along with people are grown to even greater heights to the cry of environmental protection and safety, require more and more higher to material environment friendly, the non-halogen cry of fire retardant material is day by day surging, domestic and international investigator starts all kinds of halogen-free flame retardants to be applied to PC/ABS alloy, to obtaining the halogen-free flame retardant PC/ABS product of few cigarette, low toxicity, high-efficiency environment friendly green.
At present, the halogen-free flame-retardant system of PC/ABS alloy comprises phosphorous system, nitrogen system, silicon-series five-retardant, inorganic fire-retarded system and Intumescent Retardant System.Aluminium hydroxide and magnesium hydroxide are the two kinds of inorganic combustion inhibitors commonly used the most, have nontoxic, press down cigarette, the advantage such as cheap, but the flame retarding efficiency of inorganic powdered filler is lower, addition reaches more than 40% and just likely reaches UL94V-0 flame retardant rating, inorganic combustion inhibitor and PC/ABS alloy poor compatibility in addition, high amount of inorganic filler makes the mechanical properties decrease of material in PC/ABS alloy resin serious, and outward appearance and processing characteristics and electrical property sharply worsen.Intumescent Retardant System mainly comprises acid source, charcoal source and source of the gas three elements, wherein with ammonium polyphosphate, tetramethylolmethane and trimeric cyanamide for representative, have nontoxic, press down the advantage such as cigarette, but there is exudative and water miscible problem in tetramethylolmethane, and Intumescent Retardant System is incompatible with polymkeric substance, mechanical property and the water tolerance of polymkeric substance also can be reduced, so Intumescent Retardant System is also restricted in the application of PC/ABS after adding.
Polynite takes off soil series smectite clay (comprising calcium base, sodium base, Sodium/Calcium base, magnesium base illiteracy clay) and forms through dispersion of delaminating, remodeling of purifying, super-fine classified, special organic composite, average wafer thickness is less than 25nm, is the inorganic polymer class thickening material having commercial use most.There is good dispersing property, can widespread use macromolecular material industry as the additive of nanometer polymer macromolecular material, improve shock resistance, antifatigue, dimensional stability and gas barrier property etc., thus play the effect strengthening polymkeric substance comprehensive physical performance, improve materiel machining performance simultaneously.Application in the polymer can be added when polymkeric substance, also can the blended interpolation when melting (employing screw rod is blended usually).Mainly include machine polynite, inorganic polynite, sodium-based montmorillonite, nano organic montmorillonite etc., all can be used for halogen-free flameproof, fire-retardant, activeness and quietness.
For above-mentioned reason, select the phosphorus flame retardant of the higher and water-tolerant of thermostability and in phosphorus flame retardant, introduce the flame retarding efficiency that synergist and polynite can improve PC/ABS alloy effectively.
Summary of the invention
The object of the invention is low for the flame retarding efficiency of halogen-free flame retardants to PC/ABS alloy and thermostability and poor water resistance shortcoming, a kind of polynite phosphorus system synergistic halogen-free flame retardant PC/ABS alloy material is provided, the fire retardation PC provided in the present invention/ABS alloy material adopts phosphorus system and nitrogenated flame retardant or phosphorus flame retardant and silicon system synergist is collaborative uses, and it is fire-retardant to add polynite synergistic, the flame retarding efficiency of halogen-free flame retardant PC/ABS alloy material can be improved, promote the comprehensive mechanical property, thermotolerance, electrical property etc. of halogen-free flame retardant PC/ABS alloy material; And the poisonous gas discharged in minimizing combustion processes, the few poison of low cigarette.Therefore the polynite synergistic fire retardation PC/ABS alloy material in the present invention is a kind of environmentally friendly fire retardant material.
