Embodiment 1

[0027] Under the protection of nitrogen, the 1-tetradecene of 30g is dissolved in toluene, and its mass concentration is 30%, and in the 250ml four-neck flask of packing band stirring device and reflux device, setting temperature is 70 ℃, will 20g of polyethylene glycol-400 acrylate was dissolved in toluene and poured into the reaction system, and stirring was started. After 30 minutes, the initiator 2,2'-azobisisobutyronitrile toluene solution (take 0.5g 2,2' -Azobisisobutyronitrile 10ml toluene), put into the constant pressure dropping funnel, drop in the mixed solution of polyethylene glycol-400 acrylate at a rate of 1 drop per 2 seconds, the solution viscosity gradually increases , After 20 hours of reaction, stop the reaction. Precipitate the product with ethanol, and filter it with ethanol at the same time. After repeated 3-4 times, take out the product and dry it in vacuum at 60°C for 12 hours to obtain the desired antistatic agent.

Embodiment 2

[0029] Under the protection of nitrogen, the 1-octene of 30g is dissolved in toluene, and its mass concentration is 20%, and in the 250ml four-neck flask of packing band stirring device and reflux device, setting temperature is 100 ℃, and 20g Acrylic acid polyethylene glycol-1000 ester is dissolved in toluene and poured in the reaction system, starts to stir, and after 30min, the initiator tert-butyl peroxybenzoate toluene solution (get 0.2g tert-butyl peroxybenzoate 10ml toluene middle), put it into a constant pressure dropping funnel, drop it into the mixed solution of polyethylene glycol-1000 acrylate at a rate of 1 drop per 2 seconds, the viscosity of the solution gradually increases, and stop the reaction after 15 hours of reaction. Precipitate the product with ethanol, and filter it with ethanol at the same time. After repeated 3-4 times, take out the product and dry it in vacuum at 60°C for 12 hours to obtain the desired antistatic agent.

Embodiment 3

[0031] Under the protection of nitrogen, the 1-tetradecene of 20g and the 1-hexene of 10g are dissolved in toluene, and its mass concentration is 30%, and in the 250ml four-neck flask of packing band stirring device and reflux device, set Set the temperature at 100°C, dissolve 20g of polyethylene glycol-800 acrylate in toluene and pour it into the reaction system, start stirring, and after 30min, add the initiator tert-butyl peroxybenzoate toluene solution (take 0.5g over Oxygenated tert-butyl benzoate 10ml toluene), pack in the constant pressure dropping funnel, drop in the mixed solution of polyoxyethylene glycol-800 acrylate with the dripping speed of every 2 seconds, the solution viscosity increases gradually, After 15 hours of reaction, the reaction was stopped. Precipitate the product with ethanol, and filter it with ethanol at the same time. After repeated 3-4 times, take out the product and dry it in vacuum at 60°C for 12 hours to obtain the desired antistatic agent. ...

Abstract

The invention relates to a polyethylene glycol antistatic agent and a preparation method thereof. The polyethylene glycol antistatic agent comprises the following components in parts by weight: 20-60 parts of alpha-olefin, 20-60 parts of polyethylene glycol acrylate, and 0.1-1 part of an initiator; the preparation method comprises the following steps: adding polyethylene glycol acrylate to long-chain alpha-olefin at an appropriate proportion, and generating the antistatic agent under action of the initiator. According to the invention, polyethylene glycol acrylate and long-chain alpha-olefin are copolymerized to generate a random copolymer; the random copolymer adjusts the compatibility of polyethylene glycol acrylate and polyethylene resin, can improve the antistatic property of PE resin apparently, and makes the antistatic effect more durable.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a polyethylene glycol antistatic agent for polyethylene resin and a preparation method thereof. Background technique [0002] Polyethylene (PE) is one of the most widely used polymer materials because of its wide source, low price, good resistance to chemicals and solvents, and easy processing. However, polyethylene will generate static electricity due to friction during production, processing, and use. However, polyethylene has a large volume resistance and surface resistivity, and poor conductivity, so it is difficult to eliminate charges in a short time. The accumulation of these charges will Affect the production and use of the product, cause vacuuming, electric shock, and even vicious accidents such as sparks and explosions. [0003] For polyethylene, an effective way to prevent the generation and accumulation of static electricity is to add an antista...
