Embodiment 1

[0014] The anti-radiation conductive plastic is composed of: 100 parts of bis(polyethylene glycol methacrylate), 30 parts of bis(polyethylene glycol methacrylate), 15 parts of lead methacrylate, 20 parts of lead octoate, 20 parts of galvanized carbon black.

[0015] After mixing the above-mentioned monomers and additives uniformly, heat and stir at 70 degrees Celsius for 10 minutes to prepare a uniform solution. Then cool to 40 degrees Celsius, then add 0.1%wt tert-butyl peroxybenzoate to prepare a slurry, cast a mold, polymerize at 80 degrees Celsius for 3 hours, then heat up to 120 degrees Celsius, and continue polymerization for 2 hours to obtain a finished product.

Abstract

The invention relates to a ray proof conductive plastic, which comprises the following components by mass proportion 50-100 parts of di(methacrylic acid polyethylene glycol), 30-50 parts of di(methacrylic acid polyacid neopentylene glycol ester) and 10-15 parts of methacrylic acid lead, 15-20 parts of lead octoate and 10-20 parts of galvanized carbon black. The ray proof conductive plastic has the advantages of excellent electromagnetic waves resistance, ray function resistance, high mechanical strength, scratch resistance and good heat resistance.

Description

[0001] technical field [0002] The invention belongs to the technical field of conductive plastics, in particular to a radiation-proof conductive plastic. [0003] Background technique [0004] Superconducting carbon black can improve the conductivity and processing performance of conductive plastics, and its efficiency is 6-8 times higher than that of ordinary carbon black-filled conductive plastics. Using superconducting carbon black to produce antistatic pellets can minimize the loss of properties, and using it to produce conductive pellets can overcome defects in mold filling, warpage and surface quality. The superconducting carbon powder produced by Aksu Chemical Company in the Netherlands has excellent conductivity due to its large surface area, which is about 6 times that of traditional furnace carbon black. When the Dutch DSM Engineering Plastics Company produces a new PC product (PC-50 / EC) that eliminates static electricity, it only uses carbon black with a mass ...
