Description
Technical field
The present invention relates to a kind of high-impact high fire-retardance HIPS composite and preparation method thereof, specially one kind can be applied to
The high-impact high fire-retardance HIPS composite of automobile function part, electronic apparatus parts, belongs to polymer modification and manufacture field.
Background technology
Polystyrene (HIPS) is the relatively low general-purpose plastics of current price, and it has excellent mechanics, heat resistance, resistance toization
Solvent borne, and easy processing are learned, its outstanding cost performance has in multiple fields such as automobile, household electrical appliance, food utensils widely should
With.
Yet with the structure of polystyrene itself, its oxygen index (OI) is low, and easy firing, burning velocity are fast and existing with drippage
As, it is susceptible to fire and is difficult to extinguish, this receives its application field greatly to limit, especially in household electrical appliance side
Face, its housing requirement material possesses strict fire retardant performance (UL94V0), and conventional poly styrene composite material is also very
Difficulty meets this requirement.Meanwhile, household electrical appliance also have comparing requirement high when actually used to the shock resistance of material.
The content of the invention
The invention provides a kind of high-impact high fire-retardance HIPS composite and preparation method thereof, ensure that material has
While excellent shock resistance, its fire resistance is greatly improved, and anti-flammability can bring up to UL94V0 grades, can be answered extensively
For automobile function part, electronic apparatus parts etc..
The purpose of the present invention is achieved through the following technical solutions：
A kind of high-impact high fire-retardance HIPS composite and preparation method thereof, including percentage by weight meter following raw material：
Described HIPS resins are injection polystyrene.
Described halogenated flame retardant is bromide flame retardant.Preferably TDE, deca-BDE and eight bromo ether
In one kind.
Described flame retardant is antimony oxide.
Described bulking agent is selected from (styrene/acrylonitrile) copolymer, (ethylene/acrylic acid) copolymer, styrene-grafted
One kind in copolymer-maleic anhydride, SBS.
The preparation method of above-mentioned high-impact high fire-retardance HIPS composite, its step is：
(1) raw material is weighed by above-mentioned percentage by weight, is well mixed；
(2) in the raw material after mixing being put into the main barrel of double screw extruder, screw diameter 35mm, draw ratio L/D
=36, machine barrel Discrete control temperature, from charge door to head outlet for 170 DEG C, 175 DEG C, 175 DEG C, 175 DEG C, 175 DEG C, 175
DEG C, engine speed is 300 revs/min, by obtaining product after the operations such as melting extrusion, tank cooling, dried process, pelletizing.
By the high-impact high fire-retardance HIPS composite prepared by the present invention, ensure that material has excellent anti-impact
While hitting performance, its fire resistance is greatly improved, and anti-flammability can bring up to UL94V0 grades, can be widely applied to automobile work(
Energy part, electronic apparatus parts etc..
Specific embodiment
Below by specific embodiment, the present invention is further illustrated, but the embodiment is merely to illustrate the present invention
Rather than limitation of the present invention.
The embodiment of the present invention is raw materials used：
HIPS resins：Polystyrene, model PH88, Zhenjiang Qi Mei companies；
Fire retardant：TDE, Shanghai Heng Mu companies.

Bulking agent：Elastomer, model YH792, China Petrochemical Industry Company；
Properties of product are tested：
Tensile strength is tested：Carried out by ISO 527-2 standards, specimen size is 170*10*4mm, draw speed is 50mm/
min。
Bending strength is tested：Carried out by the standards of ISO 178, specimen size is 80*10*4mm, rate of bending is 2mm/min,
Span is 64mm.
Notch impact strength is tested：Carried out by ISO 179-1 standards, specimen size is 80*10*4mm.
Vertical combustion grade：By UL94 standard testings, the sample of 1.6 mm of thickness.
The formula and properties test result of embodiment and comparative example see below each table：
The embodiment 1~5 of table 1 and material prescription table (weight %) of comparative example 1~3
The embodiment 1~5 of table 2 and the test result of comparative example 1~3
By comparing embodiment 1,2,3 and comparative example 1,2,3, the addition of fire retardant significantly improves HIPS materials
Anti-flammability, and with the gradually increase of fire retardant, the anti-flammability of HIPS materials is gradually stepped up.By comparing embodiment 2,4,5
Understand that the addition of bulking agent significantly improves the shock resistance of HIPS materials with comparative example 1,2,3, and with bulking agent
Gradually increase, the shock resistance of HIPS materials gradually strengthens.
By the high-impact high fire-retardance HIPS composite prepared by the present invention, ensure that material has excellent anti-impact
While hitting performance, its fire resistance is greatly improved, and anti-flammability can bring up to UL94V0 grades, can be widely applied to automobile work(
Energy part, electronic apparatus parts etc..
