Flame retardant permanent anti-static acrylonitrile butadiene styrene (ABS) /polyethylene terephthalate (PET) alloy and preparation method thereof

Abstract

The invention discloses a flame retardant permanent anti-static acrylonitrile butadiene styrene (ABS) / polyethylene terephthalate (PET) alloy and a preparation method thereof. The flame retardant permanent anti-static ABS / PET alloy includes the following components of, by weight, 45% to 72% of ABS resins, 2% to 10% of PET, 10% to 20% of permanent anti-static agents and 15% to 25% of flame retardants. The preparation method includes adding each of the components according to the ratio into a high speed mixer for evenly mixing, feeding the mixtures into a double-screw extruder, and subjecting the mixtures to mixing, extruding, drawing, cooling and granule-cutting, and obtaining the flame retardant permanent anti-static ABS / PET alloy. The flame retardant permanent anti-static ABS / PET alloy has a good tenacity, an excellent flame retardant performance and an excellent anti-static performance, and is capable of greatly reducing product costs on the premise of meeting basic applications.

Description

technical field [0001] The invention belongs to the technical field of functional polymer materials, and in particular relates to a flame-retardant permanent antistatic ABS / PET alloy and a preparation method thereof. Background technique [0002] ABS resin has excellent comprehensive properties and is widely used in household appliances, electronic appliances, office equipment, automobile industry, etc., and is one of the five general-purpose plastics. However, the oxygen index (OI) of ABS is 18, which is a flammable material. Therefore, flame retardant modification must be carried out when it is used in electrical appliances; Electrostatic breakdown products will cause personal injury and death more seriously. Therefore, it is necessary to eliminate static electricity for ABS materials. PET is also a widely used material, its price is lower than that of ABS, and it is easy to recycle. At present, the recycling of PET has formed a relatively complete industrial system. Fro...

Problems solved by technology

[0003] Chinese patent document CN 101709126 A discloses that brominated flame retardants and antimony-based flame retardants are compounded in ABS resin to achieve flame retardant effects, and antistatic effects are achieved by adding small-molecule antistatic agents, but small-molecule antistatic agents The antistatic effect of antistatic agent is easy to fade gradually with the extension of time, and the antistatic effect is very dependent on the environmental humidity, which affects the practical application of the material

Although the above-mentioned modification measures have improved the mechanical properties of the ABS / PET blend system, due to the high price of the compatibilizer and toughener used, the cost of the material has been greatly increased, which greatly limits its application in industry.
