Description
Technical field
The present invention relates to a kind of PC/ABS matrix material, be specifically related to a kind of high dispersive type environment-friendly high-efficiency PC/ABS composite flame-proof material and preparation method thereof.
Background technology
Polycarbonate (PC) transparency is high, and light specific gravity has excellent mechanical property, Heat stability is good, flame retardant properties is good, is used as fire retardant material widely, but its maximum shortcoming is to wear no resistance, easily stress cracking, not acid and alkali-resistance, governs applying of PC flame retardant products.In order to improve the performance of PC material, often carry out modification to it, acrylonitrile-butadiene-styrene copolymer (ABS) has the advantages such as heat-resisting, shock-resistant resistance, hardness are high, good stability of the dimension, is usually used in the modification of PC.
Mostly existing environmental protection class fire retardation PC material is directly in preparation process, to add fire retardant on the market, result in fire retardant skewness in the material, raw material availability is on the low side, flame retardant effect is barely satisfactory, therefore necessary conventional formulation and technique to be improved, obtained gratifying flame retardant effect.
Summary of the invention
The object of the invention is to, provide a kind of high dispersive type environment-friendly high-efficiency PC/ABS composite flame-proof material and preparation method thereof, improve the flame retardant properties of matrix material, to achieve these goals, the technical solution used in the present invention is as follows:
A kind of high dispersive type environment-friendly high-efficiency PC/ABS composite flame-proof material and preparation method thereof, it is characterized in that, this compound material is made up of the raw material of following weight part: PC 40-50, ABS 15-20, glass flake 2-4, mesopore molecular sieve 5-8, triphenylphosphate 2-3, methyl-silicone oil 2-3, glycidyl methacrylate 5-8, distearyl pentaerythrityl diphosphite 0.1-0.2, the different phenylpropyl alcohol 0.1-0.2 of peroxidation two, silane coupling agent 0.1-0.2, nano aluminium oxide 3-5.
Described a kind of high dispersive type environment-friendly high-efficiency PC/ABS composite flame-proof material and preparation method thereof, it is characterized in that, described preparation method comprises following steps:
(1) first the methyl-silicone oil of glass flake with 1-2 weight part is mixed, after stirring, it is mixed with PC, drop in high speed mixer together and mix, send into extruding pelletization in dual-screw pelletizer, obtain modification PC master batch for subsequent use;
(2) methyl-silicone oil that nano aluminium oxide and remainder are measured is mixed, after stirring, it is mixed with ABS, drop in high speed mixer together and mix, send into extruding pelletization in dual-screw pelletizer, obtain modified ABS master batch for subsequent use;
(3) by mesopore molecular sieve, silane coupling agent, triphenylphosphate mixing; 20-30min is left standstill after stirring completely; subsequently it is mixed with the modification PC master batch of step (1) gained, the modified ABS master batch of step (2) gained and other remaining component; send into extruding pelletization in dual-screw pelletizer, obtain PC/ABS matrix material.
Beneficial effect: the present invention is first by PC, ABS first carries out pre-modification respectively, material modified mechanical property after process and consistency improve, last again by modified PC, ABS masterbatch is cross-linked mixing granulation, and using mesopore molecular sieve as solid support material, by the load of fire retardant triphenylphosphate thereon, fire retardant after such process disperses more even between master batch, utilization ratio is improved, the finished product compound material prepared not only combines the advantage of PC and ABS efficiently, flame retardant properties gets a promotion further, the consumption of fire retardant also must reduce, production cost is controlled.
