Embodiment 1

[0030] This embodiment provides a polyvinyl chloride plasticizing 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 left to polymerize 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. Using a rotary evaporator to remove the organic solvent, a polyallyl glycidyl ether (PAGE) intermediate product was obtained.

[0032] (2) 2.5 g of the above-mentioned intermediate product PAGE, 4 g of n-butanethiol, 8.12 mg of ruthenium terpyridine 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 hours to complete the reaction. After the reaction, unreacted n-butanethiol, solvent and catalyst were removed by dialysis in ethanol. Usi...

Embodiment 2

[0034] This embodiment provides a polyvinyl chloride plasticizing 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 allowed to polymerize at 60°C for 2 hours. After that, sulfuric acid was added to the system to terminate the polymerization reaction. The precipitate was removed by filtration. Using a rotary evaporator to remove the organic solvent, a polyallyl glycidyl ether (PAGE) intermediate product was obtained.

[0036] (2) 2.5 g of the above-mentioned intermediate product PAGE, 2 g of n-butanethiol, 8.12 mg of ruthenium terpyridine 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 hours to complete the reaction. After the reaction, unreacted n-butanethiol, solvent and catalyst were removed by dialysis in ethanol. Usi...

Embodiment 3

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

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

[0040] (2) 2.5 g of the above intermediate product PAGE, 5 g of n-butanethiol, 8.12 mg of ruthenium terpyridine 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. Using rotary evaporation to re...

Abstract

A polyvinyl chloride plasticizer and antistatic agent and a preparation method thereof. The potassium tert-butoxide and allyl glycidyl ether are dissolved in an anhydrous solvent; the solution is placed at 40-80 DEG C for polymerization for 2-24 hours; , adding an acidic substance to the system to terminate the polymerization reaction, filtering to remove the precipitate, and using a rotary evaporator to remove the organic solvent to obtain the polyallyl glycidyl ether intermediate product; Step 2: the above intermediate product PAGE, n-butanethiol and The photocatalyst is dissolved in an organic solvent, the solution is placed at room temperature, and the reaction is completed by irradiating it with blue light for 0.5 to 2 hours. Evaporate and remove ethanol to obtain polyvinyl chloride plasticizing antistatic agent. The invention can reduce the technological process in the actual processing process, save the cost of adding the auxiliary agent, and realize the composite function of the auxiliary agent.

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 properties, some additives are usually added during the processing of its products to improve its processing properties and product properties. Commonly used additives include plasticizers, antistatic agents, heat stabilizers, etc. [0003] Plasticizers are an indispensable and largest type of additives in the processing of soft PVC. Traditional phthalate plasticizers have been limited in many fields due to their high toxicity and poor migration resistance, such as children's toys and medical products. Compared with traditional small-molecule plasticizers, polymer plasticizers have the advantages of low toxicity and good migration resistance,...
