Problems solved by technology

The DOP of PVC products in medical devices is released into the patient's body, which will cause greater harm to the patient
In 2005, the European Union issued a warning: the baby bottle teat originating in China contains DOP, which does not meet the relevant hygienic standards and is prohibited from sale.

Embodiment 1

[0015] Take 100 parts of 1,3-diglycidyl-S-triazinetrione, put it into a 1000mL single-necked flask, add 2 parts of diethylenetriamine and 1 part of carbonamide, and turn on the rotary evaporator to heat up (oil bath heating) , the speed is 3°C / min, the temperature is raised to 60°C, the temperature is stopped, and the stirring is continued for 20 minutes, then 0.1 part of IPDI, 0.01 part of antioxidant AT215, 0.01 part of dibutyltin dilaurate are added, the temperature is raised to 130°C, and rotary distillation is obtained for 3 hours to obtain Viscous plasticizer after modification.

Embodiment 2

[0017] Take 100 parts of 1,3-diglycidyl-S-triazinetrione, put it into a 1000mL single-necked flask, add 4 parts of diethylenetriamine and 3 parts of carbonamide, turn on the rotary evaporator to heat up (oil bath heating) , the speed is 2°C / min, after the temperature rises to 70°C, stop the heat rise, continue to stir for 30 minutes, then add 0.4 IPDI, 0.03 antioxidant DSTDP, 0.3 stannous octoate and tetrabutyl titanate, heat up to 130°C, and rotate to distill 3h, the viscous plasticizer after modification was obtained.

Embodiment 3

[0019] Take 100 parts of 1,3-diglycidyl-S-triazinetrione into a 1000mL single-necked flask, add 5 parts of diethylenetriamine and 4 parts of carbonamide, turn on the rotary evaporator to heat up (oil bath heating), The speed is 2°C / min. After the temperature rises to 80°C, stop the temperature rise and continue to stir for 30 minutes, then add 0.9 parts of IPDI, 0.07 parts of antioxidant AT215 and antioxidant DSTDP (the mixing ratio of the two is 1:1), 0.7 parts of dilaurel dibutyltin titanate and tetrabutyl titanate (the mixing ratio of the two is 1:1), heated up to 140°C, and rotated for 5 hours to obtain a viscous plasticizer after modification.

Abstract

The invention discloses a soft poly vinyl chloride (PVC) plasticizer and a preparation method thereof. The method comprises enabling 1,3-diglycidyl-S-triazine triketone to serve as a raw material, adding diethylenetriamine, carbamide, isophorone diisocyanate (IPDI), an antioxidant and a catalyst, and obtaining the viscous plasticizer after oil bath heating and rotating distillation. The plasticizer prepared through the method is non-toxic, environment-friendly, good in compatibility with PVC resin, low in production cost, high in plasticization efficiency and good in durability and environment-friendliness.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a soft PVC plasticizer and a preparation method thereof. Background technique [0002] Plasticizer is the largest production and consumption variety of processing aids in the plastics industry. Its output accounts for about 60% of the total plastic additives. It is mainly used in polyvinyl chloride products, and its consumption accounts for 80% of the total plasticizers. %. At present, the plasticizers used by the vast majority of plastic companies in my country are DOP (dioctyl phthalate), DINP (diisononyl phthalate) and DBP (dibutyl phthalate), etc. This type of plasticizer is also widely used in soft products such as PVC hoses, artificial leather, and films. Since the content of some metal elements in plasticizers exceeds the standard, strictly speaking, they are not new environmental protection materials, and it is difficult to meet the requirements in many propert...
