Problems solved by technology

[0006] The Chinese invention whose publication number is CN101157781A discloses an antistatic polystyrene composition, a preparation method and a sheet. Insufficient: Sodium perchlorate, a strong oxidant, is used in its preparation method, which causes the product to be easily oxidized and cause discoloration during processing above 120 degrees Celsius. It is not suitable for materials with a processing temperature higher than 200 degrees, such as a melting point higher than 240 degree of PET

Embodiment 1

[0028] 100 parts of polyethylene glycol monomethyl ether methacrylate, 80 parts of methyl methacrylate, 10 parts of sodium methacrylate, 5 parts of sodium silicate and 0.5 part of AIBN, mix in a closed reaction pot, add anhydrous Stir 30 parts of ethanol until dissolved, heat up to 70°C, condense and reflux, take out of the pot after reacting for 2 hours, pour it into an evaporation container, react at 90°C for 1 hour, and react at 120°C for 4 hours, and finally obtain high-temperature resistant polyester ether polymer type anti-corrosion Static agent. Under the condition of temperature 21.5℃ and relative humidity R.H60%, the measured surface resistivity of the sample (according to ASTM D257 standard) is 6×10 6 Ω / sq.

[0029] The sodium methacrylate in this example can be replaced by a mixture whose molar ratio is methacrylic acid:sodium carbonate=2:1, and the same surface resistivity can be obtained.

Abstract

The invention belongs to the polymer material field and in particular to a poly(ester-ether) polymer antistatic agent. The polymer antistatic agent mainly comprises the following raw materials in parts by weight: 100 parts of poly(ethylene glycol) methyl ether methacrylate, 30-250 parts of methylmethacrylate, 2-50 parts of the mixture of sodium methacrylate or methacrylic acid and sodium carbonate, 1-30 parts of sodium silicate and 0.1-5 parts of azodiisobutyronitrile (AIBN). In the preparation method in the invention, unstable and poisonous sodium perchlorate is not adopted, thus the production process becomes more environmentally friendly. In addition, by adopting the preparation method, the temperature resistance characteristics of the product can be increased and the application rangecan be expanded; and the polymer antistatic agent can be used in the antistatic materials such as polyethylene terephthalate (PET), polybutyleneterephthalate (PA), polybutylene (PB), poly ethylene (PE), propene polymer (PP), poly styrene (PS), acrylonitrile butadiene styreneacrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC) and polyethylene (PLA). In the preparation method in the invention, the solid antistatic agent suitable for granulation can be obtained without adding coupling agent, thus the cost is lower, the electrical property is better and the surface resistivity is up to 106-107 omega/sq.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a polyester ether polymer antistatic agent. Background technique [0002] At present, plastic products are widely used in the packaging and transportation of electronic products, but the surface resistance of ordinary plastics is greater than 10 12 Ω or more, the conductivity is extremely poor, and static electricity is easily generated during the packaging and transportation of electronic products and is not easy to conduct away, causing great harm to electronic products. Therefore, it is imperative to develop and produce modified antistatic plastics. The surface resistivity of ordinary antistatic plastics produced at present is mostly in the range of 10 9 -10 11 Ω / sq, although it has certain antistatic properties, it can only meet the needs of low-end electronic products with low electrostatic sensitivity. However, with the development of the electronics industry...
