Problems solved by technology

As mentioned above, trimethylolpropane esters have poor physical properties because one-component esters have too many weak bonds to function as plasticizers, even in the absence of compatibility with PVC resins Also (US Patent No. 3939201)

Embodiment 1

[0030] (Preparation of plasticizer composition containing trimethylolpropane ester)

[0031] 268.36 grams of trimethylolpropane, 576.84 grams of 2-ethylhexanoic acid, 366.39 grams of benzoic acid, 50 grams of xylene as an entrainer substance, and 2.83 grams of tetraisopropyl titanate as a catalyst were added to a 2 In a 4-neck round bottom flask equipped with a stirrer and a condenser, the reaction was carried out for 10 hours by raising the temperature of the mixture to 220°C.

[0032] After the reaction, use a vacuum pump to evacuate the flask to 2mmHg at 200°C, remove unreacted acid, and neutralize the contents of the flask with 5% by weight of sodium hydroxide, wash and dry, and then add absorbent to the resultant , and filtered to obtain a mixture of trimethylolpropane esters.

[0033] The composition ratio of the composition is 18.21% by weight of trimethylolpropane-tri-2-ethylhexanoate, 42.82% by weight of 2,2-bis-2-ethylhexanoylmethoxybutyl benzoate, 31.23% by weight...

Embodiment 2

[0047] Trimethylolpropane esters and samples were prepared by the same method as in Example 1, except that the raw materials and quantities are shown in Table 1 below, and the results of measuring the esters for physical properties are shown in Table 2 below.

[0048] The composition ratio of the ester mixture is 25.65% by weight of trimethylolpropane tri-2-ethylhexanoate, 44.72% by weight of 2,2-bis-2-ethylhexanoylmethoxybutyl benzoate, 24.05% by weight of 2,2-bis-benzoylmethoxybutyl 2-ethylhexanoate, 3.47% by weight trimethylolpropane tribenzoate, and 2.11% by weight other ingredients.

Embodiment 3

[0050] Trimethylolpropane esters and samples were prepared by the same method as in Example 1, except that the raw materials and quantities are shown in Table 1 below, and the results of measuring the esters for physical properties are shown in Table 2 below.

[0051] The composition ratio of the ester mixture is 34.51% by weight trimethylolpropane tri-2-ethylhexanoate, 44.56% by weight 2,2-bis 2-ethylhexanoyl methoxybutyl benzoate, 17.52% by weight 2,2-bis-benzoylmethoxybutyl 2-ethylhexanoate, 1.38% by weight of trimethylolpropane tribenzoate, and 2.03% by weight of other ingredients.

Abstract

The present invention relates to a trimethylolpropane ester-based plasticizer composition for polyvinyl chloride resin, more particularly a plasticizer composition comprising trimethylolpropane ester capable of using as plasticizer of polyvinyl chloride resin. The present invention can prepare polyvinyl chloride resin having superior tensile strength, elongation, migration, and sheet heating loss etc. by using the plasticizer composition.

Description

field of invention [0001] The present invention relates to a trimethylolpropane ester-based plasticizer composition, more particularly a trimethylolpropane ester-based plasticizer composition used as a plasticizer in the preparation of polyvinyl chloride resin. Background technique [0002] Polyvinyl chloride (PVC) is a common resin, properly mixed with some additives, such as stabilizers, fillers, pigments and plasticizers, it can obtain various physical processing properties. Polyvinyl chloride, which has various physical processing properties, is widely used as a raw material for various items such as wallpaper, gloves, and toys, and is also used for pipes, wire insulation materials, and artificial leather. In order to impart various physical properties to polyvinyl chloride resin, such as processability, flexibility, electrical insulation, etc., plasticizers are necessary additives for the preparation of polyvinyl chloride. [0003] Typic...
