Embodiment 1

[0011] The formula of typical polyvinyl chloride resin given according to the present invention is as follows table 1,

[0012] Table 1

[0013]

[0014] Note: A is a suspended polyvinyl chloride with a K value of 70.

[0015] When using the mixtures in Table 1 to produce calendered sheets, the calendered sheets added with epoxidized soybean oil and alkylpyrrolidone were softer and more transparent than those added with dioctyl phthalate. The plate with added tetradecylpyrrolidone is the most plastic.

Embodiment 2

[0017] Provide the formula of following table 2 according to the present invention,

[0018] Table 2

[0019]

[0020] Note: A is a suspended polyvinyl chloride with a K value of 70.

[0021] When using the mixtures in Table 2 to produce calendered sheets, the calendered sheets added with epoxidized soybean oil and alkylpyrrolidone were softer and more transparent than those added with dioctyl phthalate. The plasticity of the composition containing 10% epoxidized soybean oil was the best.

Embodiment 3

[0023] Provide the formula of following table 3 according to the present invention,

[0024] table 3

[0025]

[0026] Note: B is a suspended polyvinyl chloride with a K value of 71.

[0027] The temperature of 200° C. was used to produce the calendered sheet with the mixtures of various proportions in Table 3, so Ca / Zn stabilizers were added.

[0028] The Shore A hardness of the calendered sheet produced by using the mixture of various proportions in Table 3 was measured, as shown in Table 4 below. It can be seen from Table 4 that adding 40phr of the composition and adding 80phr of dioctyl phthalate The same Shore A hardness can be obtained, that is, the composition can bring the polyvinyl chloride resin to the desired plasticized state more easily than dioctyl phthalate.

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 theplasticizer 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 polyvinylchloride 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 [0001] The invention relates to a composition used as a plasticizer for polyvinyl chloride resin, and a specific use method when the composition is used as a plasticizer. Background technique [0002] It is well known that some commonly used thermoplastic polymers have a glass transition temperature (Tg) higher than room temperature. Below this temperature, the polymer exhibits a brittle state similar to glass. properties and impact strength. In order for a polymer to have practical value, its glass transition temperature must be lowered below the use temperature. Plasticizers are a class of additives introduced into polymers to solve this problem. [0003] The plasticizer in polyvinyl chloride resin plays a plasticizing role by reducing the cohesive energy density between polymer chains and the polar attraction between halogen atoms in polyvinyl chloride resin. [0004] At present, a large number of organic compounds have been reported as plasticizers for...
