Abstract
The invention relates to a permanent anti-static electricity acrylonitrile butadiene styrene (ABS) composite material and a preparation method of the permanent anti-static electricity ABS composite material. The material comprises the following components and part by weight contents: 3-8 parts of a self-control anti-static electricity master batch, 80-95 parts of the ABS and 1-5 parts of a compatilizer. Raw materials are weighed and taken according to the weight ratio. The raw materials are placed in a high mixing machine and the raw materials are blended for 2-5 minutes. The raw materials are discharged. Then pelletings are squeezed from a double screw rod extruder. The machining temperature is 190-225 DEG C. The number of revolutions of a screw rod is 35-40 HZ. Compared with the prior art, the permanent anti-static electricity ABS composite material has the advantages that the anti-static electricity effect is permanent and the effect of permanent anti-static electricity is achieved. The anti-static electricity effect is good. Analyse mechaniscs performance is high. The permanent anti-static electricity ABS composite material is close to the pure ABS performance. Color is light. The permanent anti-static electricity ABS composite material can be matched to various kinds of colors. The permanent anti-static electricity ABS composite material has the advantages of being low in cost, good in heat resistance and the like. Surface electrical resistivity of the permanent anti-static electricity ABS composite material can be arrived at 106-108 omega-m.
Description
technical field [0001] The invention relates to an antistatic composite material and a preparation method thereof, in particular to a permanent antistatic ABS composite material and a preparation method thereof. Background technique [0002] ABS resin is a yellowish solid with a certain toughness and a density of about 1.04-1.06g / cm 3 . It has strong resistance to acid, alkali and salt corrosion, and can also tolerate organic solvent dissolution to a certain extent. [0003] ABS resin can perform normally in the environment of -25 ℃ ~ 60 ℃, and has good formability. The processed product has a smooth surface and is easy to dye and electroplate. It is suitable for making general mechanical parts, corrosion-resistant parts and automobile and electrical parts. But ABS, like most polymer materials, has good electrical insulation, and its surface resistivity is generally around 10. 13 -10 15 Ω.m, the conductivity is much smaller than that of metal materials. It is easy to a...
