Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a conductive anti-aging ABS composite plastic and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer (ABS) is synthesized from three chemical monomers of acrylonitrile, butadiene and styrene. The polymerization of the three monomers produces a terpolymer with two phases. One is a continuous phase of styrene-acrylonitrile, and the other is a dispersed phase of polybutadiene rubber. ABS combines the different characteristics of each monomer. It has high strength, thermal stability and chemical stability, impact resistance, easy processing, high finish and high strength. It is easy to paint and color, and can also be used for various mechanical applications. It is widely used in automobiles, electronic appliances, machinery, instrumentation and construction, and is one of the most widely used general-purpose plastics. [0003] Howev...

Problems solved by technology

[0003] However, since the ABS molecule contains double bonds, it will be oxidatively degraded during use due to ultraviolet light, oxygen, acid, high temperature, etc., which will cause the material to change color and age, and shorten the overall service life of ABS composite plastics.

In addition, due to the insulation of the plastic material itself, it is easy to accumulate charges, resulting in the inability to release the static charge accumulated on the surface of the plastic product, thereby forming a static voltage, which is easy to absorb dirt such as dust. When the static voltage reaches a certain level, electrostatic discharge and electric shock will occur Phenomenon

In the electronics industry, precision electronic devices will be damaged or even scrapped due to electrostatic breakdown. If the accumulated static electricity is not released well, it will bring more serious consequences such as fire or explosion.
