Embodiment 1

[0030] This embodiment provides a polyvinyl chloride plasticized antistatic agent, which is prepared by the following method:

[0031] (1) Dissolve 0.6 g of potassium tert-butoxide and 6 g of allyl glycidyl ether in anhydrous tetrahydrofuran. The solution was polymerized at 60°C for 24 hours. After that, hydrochloric acid was added to the system to terminate the polymerization reaction. The precipitate was removed by filtration. The organic solvent was removed by a rotary evaporator to obtain the intermediate product of polyallyl glycidyl ether (PAGE).

[0032] (2) 2.5 g of the above intermediate product PAGE, 4 g of n-butanethiol, 8.12 mg of terpyridyl ruthenium chloride and 73.63 mg of p-toluidine were dissolved in N-methylpyrrolidone. The solution was left at room temperature and irradiated with blue light for 0.5 h to complete the reaction. After the reaction, unreacted n-butanethiol, solvent and catalyst were removed by dialysis in ethanol. Ethanol is removed by rota...

Embodiment 2

[0034] This embodiment provides a polyvinyl chloride plasticized antistatic agent, which is prepared by the following method:

[0035] (1) Dissolve 0.6 g of potassium tert-butoxide and 3 g of allyl glycidyl ether in anhydrous tetrahydrofuran. The solution was placed at 60°C for 2 hours to polymerize. After that, sulfuric acid was added to the system to terminate the polymerization reaction. The precipitate was removed by filtration. The organic solvent was removed by a rotary evaporator to obtain the intermediate product of polyallyl glycidyl ether (PAGE).

[0036] (2) 2.5 g of the above-mentioned intermediate product PAGE, 2 g of n-butanethiol, 8.12 mg of terpyridyl ruthenium chloride and 73.63 mg of p-toluidine were dissolved in N,N-dimethylformamide. The solution was left at room temperature and irradiated with blue light for 0.5 h to complete the reaction. After the reaction, unreacted n-butanethiol, solvent and catalyst were removed by dialysis in ethanol. Ethanol is...

Embodiment 3

[0038] This embodiment provides a polyvinyl chloride plasticized antistatic agent, which is prepared by the following method:

[0039] (1) Dissolve 0.6 g of potassium tert-butoxide and 60 g of allyl glycidyl ether in anhydrous toluene. The solution was placed at 40°C for 24 hours to polymerize. After that, phosphoric acid was added to the system to terminate the polymerization reaction. The precipitate was removed by filtration. The organic solvent was removed by a rotary evaporator to obtain the intermediate product of polyallyl glycidyl ether (PAGE).

[0040] (2) 2.5 g of the above intermediate product PAGE, 5 g of n-butanethiol, 8.12 mg of terpyridyl ruthenium chloride and 73.63 mg of p-toluidine were dissolved in ethanol. The solution was left at room temperature and irradiated with blue light for 2 hours to complete the reaction. After the reaction, unreacted n-butanethiol, solvent and catalyst were removed by dialysis in ethanol. Ethanol is removed by rotary evapora...

Abstract

The invention relates to a polyvinyl chloride plasticizing antistatic agent and a preparation method thereof. The preparation method comprises the following steps: dissolving potassium tert-butoxide and allyl glycidyl ether in an anhydrous solvent; polymerizing the solution for 2-24 hours at the temperature of 40-80 DEG C; then adding an acidic material into the system to terminate the polymerization reaction, performing filtering to remove the precipitate, and removing the organic solvent by using a rotary evaporator to obtain a polyallyl glycidyl ether intermediate product; and 2, dissolving the intermediate product PAGE, n-butyl mercaptan and a photocatalyst in an organic solvent, placing the solution at room temperature, irradiating the solution with blue light for 0.5-2 hours to complete a reaction, dialyzing the solution in ethanol to remove unreacted n-butyl mercaptan, the solvent and the catalyst after the reaction is finished, and removing the ethanol by rotary evaporation to obtain the novel polyvinyl chloride plasticizing antistatic agent. According to the invention, the technological process in the actual processing process can be reduced, the addition cost of the additive is saved, and the composite function of the additive is realized.

Description

technical field [0001] The invention relates to the technical field of fine chemical additives, in particular to a polyvinyl chloride plasticizing antistatic agent and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the most widely used polymer materials. However, due to its insufficient performance, some additives are usually added during the processing of its products to improve its processing performance and product performance. Commonly used additives include plasticizers, antistatic agents, heat stabilizers, etc. [0003] Plasticizer is an essential and most used additive in the processing of soft PVC. Traditional phthalate plasticizers have been restricted in many fields due to their high toxicity and poor migration resistance, such as children's toys, medical products, etc. Compared with traditional small molecule plasticizers, polymer plasticizers have the advantages of low toxicity and good migration resistance, and ...
