Abstract
The invention discloses a nontoxic plasticizer compound which can reduce the melt temperature of polyvinyl chloride resin, increase the softness of polyvinyl chloride resin and an application method of the plasticizer compound. The mass percentages of the components of the compound are 10 to 90 percent epoxy soybean oil and 10 to 90 percent alkyl pyrrolidone C12-C18. The content of compound as the plasticizer of the polyvinyl chloride resin in the polyvinyl chloride resin is 10 to 100 phr. The nontoxic plasticizer compound has the advantages that: when the compound is added into the polyvinyl chloride resin, the polyvinyl chloride resin has a performance of less than 100 Shore A hardness, the polyvinyl chloride resin with the compound is suitable for manufacturing calendering plates, plastisol, film, nominal tubes and tube fittings.
Description
Technical field
The present invention relates to a kind of composition as the polyvinyl chloride (PVC) RESINS softening agent, and the concrete using method of said composition during as softening agent.
Background technology
As everyone knows, some thermoplastic polymers commonly used have the second-order transition temperature (Tg) that is higher than room temperature, and below the temperature, polymkeric substance shows as the glazed brittle state of class at this, more than the temperature, then present bigger rebound resilience, snappiness and shock strength at this.Make polymkeric substance have practical value, its second-order transition temperature is dropped to below the use temperature.Softening agent is exactly an analog assistant of introducing in the polymkeric substance for addressing this problem.
Softening agent in the polyvinyl chloride (PVC) RESINS is to play plastification by the polar attraction power that reduces between the halogen atom in polymkeric substance interchain cohesive energy density(CED) and the polyvinyl chloride (PVC) RESINS.
At present, a large amount of organism has been in the news and has can be used as the softening agent of polyvinyl chloride (PVC) RESINS.Comprising Tetra hydro Phthalic anhydride and C
4-C
15Ester class, epoxy soybean oil, trimellitate, benzoate and citrate and halohydrocarbon etc. that Fatty Alcohol(C12-C14 and C12-C18) (straight or branched) reaction obtains.The high-molecular weight polyester that dibasic alcohol and hexanodioic acid or sebacic acid reaction obtain also is used as softening agent.In these softening agent, the most extensive with the use of phthalic ester plasticizer.Also there are some shortcomings in above-mentioned softening agent, if any carinogenicity arranged, cause endocrine regulation easily, bigger etc. to genotoxicity; The low-temperature pliability of resin, ductibility are good etc. after the use that has.
Summary of the invention
A technical problem to be solved by this invention is: will provide a kind of nontoxic, can reduce the polyvinyl chloride (PVC) RESINS melt temperature, improve the composition as the polyvinyl chloride (PVC) RESINS softening agent of polyvinyl chloride (PVC) RESINS flexibility, another problem that the present invention will solve is: the concrete using method that above-mentioned composition will be provided.
For solving above-mentioned first problem, the technical solution used in the present invention is: as containing mass percent in the composition of polyvinyl chloride (PVC) RESINS softening agent is 10～90% epoxy soybean oil, preferred 20～80%, especially preferred 20～60%; Contain 10～90% C in the composition
12-C
18Alkyl pyrrolidone, preferred 20～80%, especially preferred 40～80%.
For solving above-mentioned second problem, the technical solution used in the present invention is: the concrete using method of above-mentioned composition is: as the softening agent of polyvinyl chloride (PVC) RESINS, and the amount of said composition in polyvinyl chloride (PVC) RESINS is 10～100phr (with respect to the add-on of per hundred parts of resins), especially preferred 20～80phr.
Advantage of the present invention is: composition of the present invention has nontoxic, as to reduce polyvinyl chloride (PVC) RESINS melt temperature, raising polyvinyl chloride (PVC) RESINS flexibility advantage.After composition of the present invention added polyvinyl chloride (PVC) RESINS, can make polyvinyl chloride (PVC) RESINS have Shore A hardness less than 100 performance.Composition of the present invention can be used in polyvinyl chloride (PVC) RESINS separately or with one or more primary plasticizers or extender plasticizer, and these polyvinyl chloride (PVC) RESINS are fit to make calendering sheet material, plastisol, film, nominal pipe or tube members etc.
