Description
【Technical field】
The invention belongs to technical field of polymer, and in particular to a kind of environment-friendly flame-resistant ABS resin and preparation method thereof.
【Background technology】
Styrene-butadiene-acrylonitrile (ABS) resin is with the rigidity and heat resistance of acrylonitrile, the light of polystyrene
The features such as pool property and processability and the impact resistance of polybutadiene, can be widely applied to household electrical appliance, office equipment, instrument instrument
The fields such as table, communications and transportation, construction material, household utensils and packaging material.But the oxygen index (OI) of ABS resin only has 18, belongs to
Combustible material.In order to improve its burning behavior, keep its chance fire fire retardant or from fiery self-extinguishment, it is necessary to be carried out to ABS flame-retardant modified.But it is right
In the electric appliance casings such as motor, hair-dryer, power pack, micro-wave oven, electric cooker, socket or parts, in addition to requiring material that there is resistance
While combustion, also require material that there is certain heat resistance.
(acrylonitrile-butadiene-styrene copolymer, ABS are Acrylonitrile Butadiene to ABS resin
The acronym of Styrene) it is a kind of intensity height, good toughness, thermoplastics type's high molecular material easily processed into type.ABS trees
Fat is the grafting of acrylonitrile (Acrylonitrile), 1,3-butadiene (Butadiene), styrene (Styrene) three kinds of monomers
Copolymer.Its molecular formula can be written as (C8H8C4H6C3H3N) x, but actually be often that the grafting containing butadiene is total
The mixture of polymers and acrylonitritrile-styrene resin, wherein acrylonitrile accounts for 15%~35%, and butadiene accounts for 5%~30%,
Styrene accounts for 40%~60%, and most common ratio is A:B:S=20:30:50, ABS resin fusing point is 175 DEG C at this time.But ABS
The oxygen index (OI) of resin only has 18 or so, easily causes burning and leads to fire.The day realized with social development and social safety
Benefit improves, and social consensus is had become using flame-proof ABS in field of electronics.Currently, the fire retardant of production flame-proof ABS is mainly adopted
With the compound (polymer material science and engineering, 2005, volume 27, the 3rd phase) of polybrominated diphenyl ethers and antimony trioxide.From
Europe in 1986 finds polybrominated diphenyl ethers substance first, and in burning, there may be the double benzodioxans of four bromos and four bromos
Double benzofurans (plastics, 2005, volume 34.1st phase) etc. carcinogens, endangered when fire-retardant personnel safety and pollution environment,
Therefore, European Union promulgates《About being forbidden to use certain Hazardous Substances Directives in electronic electric equipment》(referred to as《RoHS refers to
It enables》), it is specified that the content of polybrominated biphenyls and polybrominated diphenyl ethers contained in flame retardant plastics must not exceed 1000PPM.
Some scholars are in order to improve the heat resistance of flame-proof ABS, usually with reinforcing agent glass fibre (GF), wollastonite, talcum
Powder etc. to flame-proof ABS carry out heat resistance modification, but this method improve flame-proof ABS heat resistance simultaneously, resistance can be significantly reduced
The toughness and mobility of ABS are fired, while ABS resin being made to lose high-luster, it is difficult to be applied in appearance member field.Another method
It is to be blended by heat-resistant agent, fire retardant and other processing aids, then prepared by double screw extruder extruding pelletization high heat-resisting
Flame-proof ABS, but since heat-resistant agent is different with fire retardant heat resistance, temperature is less than under the conditions of 240 DEG C, and heat-resistant agent dispersion is uneven, temperature
Degree is higher than 240 DEG C, and fire retardant decomposes seriously, makes the plastic particles serious yellow coloration of preparation, while specified flame retardant effect is not achieved.
There is a method in which then alloy is formed by ABS resin and other resins, such as fire retardation PC/ABS alloy, ABS/SMA alloys etc..Though
So such alloy can improve the heat resistance of flame-proof ABS resin and keep good appearance simultaneously, but the tired energy of its processing, while cost is inclined
Height is not suitable for large-scale popularization application on the market.
